Detailed ways

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

It should be noted that in the examples of the present application, "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

At present, most electronic devices, such as computers, mobile phones, etc., can play and pick up audio data. With the development of science and technology and the increase in user demand, electronic devices can be connected to external audio acquisition devices, so that the electronic devices can collect audio data (sound signals) through external audio acquisition devices. Among them, the audio acquisition device may include headphones, microphones, etc. with microphones. The above-mentioned audio acquisition device can collect audio data and transmit the collected audio data to the electronic device for processing. For example, the collected audio data can be transmitted to other electronic devices via the network via the electronic device. Among them, the electronic device can be connected to the audio acquisition device by wire or wirelessly, which is not specifically limited here.

When actually using an audio acquisition device to collect audio data and transmit it to an electronic device, users often use headphones with wireless communication to collect and transmit audio data, for example, headphones that use Wireless Fidelity (WiFi) communication, or headphones that use Bluetooth (BT) communication to collect and transmit audio data. Especially for users with higher demands, audio data can be collected and played through TWS headphones with wireless separation of the left and right channels. The above-mentioned TWS headphones can realize true wireless separation of the Bluetooth left and right channels, that is, neither of the two headphones of the TWS headphones requires a wired connection.

Among them, the TWS headset is composed of a master headset and a slave headset. The working principle is that the electronic device is connected to the master headset via Bluetooth, and the master headset and the slave headset are connected via near magnetic field induction technology (NFMI for short) or TWS protocol. In the downlink scenario, the data signal on the electronic device is transmitted to the master headset via Bluetooth, and then transmitted from the master headset to the slave headset via NFMI or TWS protocol, so that the left and right headsets receive the data signal transmitted by the electronic device; or, in the downlink scenario, the data signal on the electronic device is transmitted to the master headset via Bluetooth, and the slave headset can be disguised as the master headset to listen to and receive the data signal sent by the electronic device to the master headset, or, the slave headset can also receive the data signal sent by the electronic device to the master headset forwarded by the master headset. In the uplink scenario, the master headset works directly and the slave headset does not work, and the master headset transmits the collected audio data directly to the electronic device via Bluetooth.

In the single-earphone usage scenario of TWS earphones, in order to ensure that the TWS earphones work in the master earphone mode, the master-slave relationship of the TWS earphones is determined by wearing detection. Generally, wearing detection is achieved through a light sensor or a capacitive sensor. However, wearing detection may have detection errors. For example, when wearing a TWS earphone for a call, when the main earphone is removed and placed on the desktop, the main earphone may be placed on the desktop and mistakenly detected as being worn on the ear, resulting in the inability to switch between the main earphone and the slave earphone. The main ear is far away from the user, and the collected sound signal is weak. The user can only wear the slave earphone and cannot pick up the call sound, resulting in the other party reporting that the call volume is low or silent, reducing the quality of the user's call.

In view of the above problems, the inventor has discovered after long-term research and proposed the master-slave switching method, device, Bluetooth headset and storage medium provided in the embodiments of the present application. By controlling the switching of the master and slave headsets based on the sound signals collected by the master headset and the slave headset, the accuracy of the master-slave headset switching can be improved and the cost of the Bluetooth headset can be reduced. The specific master-slave switching method of the headset is described in detail in the subsequent embodiments.

The following describes an application environment of the master-slave switching method for the headset provided in an embodiment of the present application.

Please refer to Figure 1, which shows a schematic diagram of an application environment of a master-slave switching method for a headset provided in an embodiment of the present application. As shown in Figure 1, it includes a first Bluetooth headset 100, a second Bluetooth headset 200, and an electronic device 300. As one way, the first Bluetooth headset 100 can be used as a master headset to establish a first Bluetooth link for audio data transmission with the electronic device 300, and the second Bluetooth headset 200 can be used as a slave headset to establish a second Bluetooth link for audio data transmission with the first Bluetooth headset 100. At this time, the second Bluetooth headset 200 can establish a monitoring link for monitoring audio data transmission between the electronic device 300 and the first Bluetooth headset 100 with the electronic device 300. As another way, the second Bluetooth headset 200 can be used as a master headset to establish a first Bluetooth link for audio data transmission with the electronic device 300, and the first Bluetooth headset 100 can be used as a slave headset to establish a second Bluetooth link for audio data transmission with the second Bluetooth headset 200. At this time, the first Bluetooth headset 100 can be used as a slave headset to establish a monitoring link for monitoring audio data transmission between the electronic device 300 and the second Bluetooth headset 200 with the electronic device 300.

In some embodiments, the first Bluetooth headset 100 may be a headset that plays left channel audio data, and the second Bluetooth headset 200 may be a headset that plays right channel audio data; the second Bluetooth headset 200 may be a headset that plays left channel audio data, and the first Bluetooth headset 100 may be a headset that plays right channel audio data.

Please refer to Figure 2, which shows a schematic flow chart of a master-slave switching method for headphones provided in an embodiment of the present application. The method is used to control the switching of master-slave headphones based on the sound signals collected by the master headphone and the slave headphone, which can improve the accuracy of the master-slave headphone switching and reduce the cost of the Bluetooth headphone. In a specific embodiment, the master-slave switching method of the headphone is applied to the master-slave switching device 400 of the headphone as shown in Figure 10 and the first Bluetooth headphone 100 (Figure 11) equipped with the master-slave switching device 400 of the headphone. The following will take the Bluetooth headphone as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the Bluetooth headphone used in this embodiment may include a true wireless stereo (TWS) headphone. In this embodiment, when the first Bluetooth headphone is used as the master headphone to establish a first Bluetooth link with the electronic device, the second Bluetooth headphone is used as the slave headphone to establish a second Bluetooth link with the first Bluetooth headphone, and the first Bluetooth headphone includes a first microphone, and the second Bluetooth headphone includes a second microphone. The process shown in Figure 2 will be described in detail below. The master-slave switching method of the headphone may specifically include the following steps:

Step S110: Acquire the sound signal collected by the first microphone as the first sound signal.

In this embodiment, a first Bluetooth headset is used as a master headset to establish a first Bluetooth link with an electronic device. At this time, a second Bluetooth headset is used as a slave headset to establish a second Bluetooth link with the first Bluetooth headset to achieve data interaction between the first Bluetooth headset and the electronic device, and between the first Bluetooth headset and the second Bluetooth headset.

As a method, when the second Bluetooth headset and the electronic device have not established a monitoring link for monitoring the transmission of audio data between the electronic device and the first Bluetooth headset, if the electronic device sends audio data to the Bluetooth headsets (the first Bluetooth headset and the second Bluetooth headset), the electronic device can send the audio data to the first Bluetooth headset through the first Bluetooth link. When the first Bluetooth headset receives the audio data sent by the electronic device, it can send the audio data to the second Bluetooth headset through the second Bluetooth link, so that both the first Bluetooth headset and the second Bluetooth headset can obtain the audio data sent by the electronic device.

As another way, when the second Bluetooth headset and the electronic device establish a monitoring link for monitoring the audio data transmission between the electronic device and the first Bluetooth headset, the electronic device can send the audio data to the first Bluetooth headset through the first Bluetooth link, and the second Bluetooth headset can be disguised as the first Bluetooth headset based on the monitoring link to monitor and receive the audio data sent by the electronic device to the first Bluetooth headset via the first Bluetooth link, so that the first Bluetooth headset and the second Bluetooth headset can simultaneously obtain the audio data sent by the electronic device to reduce the delay between the first Bluetooth headset and the second Bluetooth headset. In some embodiments, the first Bluetooth headset can transmit relevant communication parameters to the second Bluetooth headset through the second Bluetooth link, so that the second Bluetooth headset can monitor the communication data of the first Bluetooth link through the relevant communication parameters, wherein the relevant communication parameters may include but are not limited to the communication connection address of the electronic device, the encryption parameter information of the communication connection, etc., so that the second Bluetooth headset does not need to perform pairing and establishment of the communication connection, but can be disguised as the first Bluetooth headset to monitor and receive the audio data sent by the electronic device via the first Bluetooth link.

In some implementations, when the electronic device needs to collect sound signals, for example, when the electronic device needs to make a call, it can be determined that the electronic device needs to collect sound signals. At this time, it is necessary to determine the main earphone from the first Bluetooth earphone and the second Bluetooth earphone to collect the sound signal. In this embodiment, the sound signal can be collected by the first Bluetooth earphone as the main earphone, and the sound signal collected by the first Bluetooth earphone is transmitted to the electronic device through the first Bluetooth link, so that the electronic device processes the sound signal collected by the first Bluetooth earphone.

In some embodiments, the first Bluetooth headset may include a first microphone. The first Bluetooth headset may control the first microphone to collect sound signals, and obtain the sound signals collected by the first microphone as the first sound signal. The first sound signal may include a voice input by a user. The number of microphones included in the first microphone may be one or more, which is not limited here.

Step S120: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

In some embodiments, the second Bluetooth headset may include a second microphone. The second Bluetooth headset may control the second microphone to collect sound signals, and obtain the sound signals collected by the second microphone as the second sound signal. The second sound signal may include a voice input by a user. The number of microphones included in the second microphone may be one or more, which is not limited here.

As an implementable manner, the second microphone of the second Bluetooth headset and the first microphone of the first Bluetooth headset can both be in working state, and the second Bluetooth headset can directly collect the sound signal through the second Bluetooth headset.

As an implementable method, if the second microphone of the second Bluetooth headset is in a sleep state, the first Bluetooth headset can send a sound signal collection instruction to the second Bluetooth headset through the second Bluetooth link, and the second Bluetooth headset can respond to the sound signal collection instruction, wake up the second microphone and control the second microphone to collect sound signals.

In some embodiments, when the second Bluetooth headset collects a sound signal through the second microphone, the sound signal collected by the second microphone can be transmitted to the first Bluetooth headset through the second Bluetooth link. Correspondingly, the first Bluetooth headset can obtain the sound signal collected by the second microphone through the second Bluetooth link, and use the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

Step S130: When the first sound signal and the second sound signal meet a preset signal condition, a switching instruction is sent to the second Bluetooth headset through the second Bluetooth link, wherein the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as a master headset.

In some embodiments, the first Bluetooth headset may be pre-set and store a preset signal condition, and the preset signal condition is used as a basis for judging the first sound signal and the second sound signal. Therefore, in this embodiment, after obtaining the first sound signal and the second sound signal, the first Bluetooth headset may compare the first sound signal and the second sound signal with the preset signal condition to determine whether the first sound signal and the second sound signal meet the preset signal condition.

As a method, when it is determined that the first sound signal and the second sound signal do not meet the preset signal conditions, it can be considered that the first Bluetooth headset is more suitable as the master headset and the second Bluetooth headset is more suitable as the slave headset. The first Bluetooth headset can be maintained as the master headset to establish a first Bluetooth link with the electronic device, and the second Bluetooth headset can be maintained as the slave headset to establish a second Bluetooth link with the first Bluetooth headset. At this time, the first sound signal collected by the first Bluetooth headset can be transmitted to the electronic device so that the electronic device can process the first sound signal.

As another way, when it is determined that the first sound signal and the second sound signal meet the preset signal conditions, it can be considered that the first Bluetooth headset is more suitable as a slave headset and the second Bluetooth headset is more suitable as a master headset, and the master headset and the slave headset can be switched, so that the first Bluetooth headset is switched from the master headset to the slave headset, and the second Bluetooth headset is switched from the slave headset to the master headset. At this time, the second sound signal collected by the second Bluetooth headset can be transmitted to the electronic device for the electronic device to process the second sound signal. The first Bluetooth headset can send a switching instruction to the second Bluetooth headset via the second Bluetooth link, and the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as the master headset.

In some embodiments, after sending a switching instruction to the second Bluetooth headset, the first Bluetooth headset may switch itself to the slave headset and disconnect the Bluetooth link with the electronic device only after receiving the indication information sent by the second Bluetooth headset to indicate that the second Bluetooth headset is ready to establish a Bluetooth connection with the electronic device, and send the connection indication information to the second Bluetooth headset at the same time as starting to switch to the slave headset, and the second Bluetooth headset immediately establishes the connection with the electronic device after receiving the connection indication information. Since the first Bluetooth headset does not switch to the slave headset immediately after sending the switching instruction, but switches after the second Bluetooth headset is ready, it can avoid the problem that the second Bluetooth headset has not established a Bluetooth link with the electronic device, but the first Bluetooth headset has disconnected the Bluetooth link with the electronic device, resulting in interruption of data transmission.

As an implementable manner, when it is necessary to switch the first Bluetooth headset from a master headset to a slave headset, and to switch the second Bluetooth headset from a slave headset to a master headset, the first Bluetooth headset can send the link information of the first Bluetooth link to the second Bluetooth headset through the second Bluetooth link; when the second Bluetooth headset receives the link information of the first Bluetooth link sent by the first Bluetooth headset, it can reply a confirmation mark (such as an ACK confirmation mark) to the first Bluetooth headset; when the first Bluetooth headset receives the confirmation mark sent by the second Bluetooth headset, it can send a switching instruction to the second Bluetooth headset through the second Bluetooth link; the second Bluetooth headset is connected to the electronic device by establishing a third Bluetooth link according to the received link information of the first Bluetooth link; when the second Bluetooth headset receives a data packet of the third Bluetooth link sent by the electronic device, the second Bluetooth headset can send a confirmation mark of successful packet reception to the first Bluetooth headset; the first Bluetooth headset can delete the first Bluetooth link and disconnect from the electronic device, so as to achieve seamless switching between the master and slave headsets and provide users with a better user experience.

In the embodiment of the present application, since the master earphone determines whether it is necessary to switch between the master and slave earphones based on the sound signal collected by the microphone of the master earphone and the sound signal collected by the microphone of the slave earphone, there is no need to set up other sensors for detecting wearing, which can reduce the cost of the Bluetooth earphone. In addition, since the master earphone is based on the sound signal collected by the microphone of the master earphone and the sound signal collected by the microphone of the slave earphone, the problem of detection errors of other sensors set up for detecting wearing can be avoided, and the accuracy of switching between the master and slave earphones can be improved.

Please refer to Figure 3, which shows a schematic flow chart of a method for switching between a master and a slave of a headset provided in an embodiment of the present application. The method is applied to a first Bluetooth headset, when the first Bluetooth headset as a master headset establishes a first Bluetooth link with an electronic device, the second Bluetooth headset as a slave headset establishes a second Bluetooth link with the first Bluetooth headset, the first Bluetooth headset includes a first microphone, and the second Bluetooth headset includes a second microphone, wherein the second microphone is in a dormant state. The process shown in Figure 3 will be described in detail below, and the method for switching between a master and a slave of a headset may specifically include the following steps:

Step S210: Acquire the sound signal collected by the first microphone as the first sound signal.

The specific description of step S210 can be found in step S110 , which will not be repeated here.

Step S220: Obtain a first sound intensity corresponding to the first sound signal.

In some embodiments, when the first Bluetooth headset obtains the first sound signal, it can process the first sound signal to obtain the sound intensity corresponding to the first sound signal as the first sound intensity. As an implementable manner, when the first Bluetooth headset obtains the first sound signal, it can calculate the first sound signal through a preset intensity algorithm to obtain the sound intensity corresponding to the first sound signal as the first sound intensity.

Step S230: When the first sound intensity is less than or equal to the first intensity threshold, a wake-up instruction is sent to the second Bluetooth headset through the second Bluetooth link, and the wake-up instruction is used to instruct the second Bluetooth headset to control the second microphone to switch from the sleep state to the working state, and collect sound signals through the second microphone.

In some implementations, the second microphone of the second Bluetooth headset is in a dormant state, that is, when the first Bluetooth headset collects sound signals through the first microphone, the second microphone does not collect sound signals, thereby reducing the power consumption of the second Bluetooth headset.

In some embodiments, the preset signal condition may include a first intensity threshold. The first Bluetooth headset may be pre-set and store a first intensity threshold, which is used as a basis for judging the first sound intensity corresponding to the first sound signal collected by the first microphone. Therefore, in this embodiment, after obtaining the first sound intensity, the first Bluetooth headset may compare the first sound intensity with the first intensity threshold to determine whether the first sound intensity is less than or equal to the first intensity threshold. Among them, the first intensity threshold may be a dividing line that characterizes whether the sound signal can be normally received by the user. For example, the first intensity threshold may be a dividing line that characterizes whether the sound signal can meet the normal call requirements in a call scenario, that is, if the sound intensity of the sound signal is less than or equal to the first intensity threshold, it can be determined that the sound signal cannot be normally received by the user, that is, the sound signal does not meet the normal call requirements in the call scenario; if the sound intensity of the sound signal is greater than the first intensity threshold, it can be determined that the sound signal can be normally received by the user, that is, the sound signal meets the normal call requirements in the call scenario.

As a method, when it is determined that the first sound intensity is greater than the first intensity threshold, it indicates that the sound signal collected by the first microphone of the first Bluetooth headset can be normally received by the user, for example, it can meet normal call needs in a call scenario. Therefore, there is no need to switch between the master and slave headsets, that is, continue to keep the first Bluetooth headset as the master headset, and keep the second Bluetooth headset as the slave headset.

As another way, when it is determined that the first sound intensity is less than or equal to the first intensity threshold, it indicates that the sound signal collected by the first microphone of the first Bluetooth headset cannot be normally received by the user, for example, it cannot meet the normal call requirements in a call scenario. Therefore, the second microphone of the second Bluetooth headset can be awakened to collect the sound signal, and determine whether to switch the master and slave headsets based on the sound signal collected by the second microphone. In some embodiments, the first Bluetooth headset can send a wake-up instruction to the second Bluetooth headset via the second Bluetooth link, and accordingly, the second Bluetooth headset can control the second microphone to switch from a dormant state to a working state in response to the wake-up instruction, and control the second microphone to collect sound signals.

Step S240: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

For the detailed description of step S240, please refer to step S120, which will not be repeated here.

Step S250: obtaining a second sound intensity corresponding to the second sound signal.

In some embodiments, when the first Bluetooth headset obtains the second sound signal, it can process the second sound signal and obtain the sound intensity corresponding to the second sound signal as the second sound intensity. As an implementable manner, when the first Bluetooth headset obtains the second sound signal, it can calculate the second sound signal through a preset intensity algorithm and obtain the sound intensity corresponding to the second sound signal as the second sound intensity.

In some embodiments, when the second Bluetooth headset collects the sound signal (second sound signal), it can process the second sound signal, obtain the sound intensity corresponding to the second sound signal as the second sound intensity, and send the second sound intensity to the first Bluetooth headset through the second Bluetooth link. As an implementable manner, when the second Bluetooth headset collects the second sound signal, it can calculate the second sound signal through a preset intensity algorithm, obtain the sound intensity corresponding to the second sound signal as the second sound intensity, and send the second sound intensity to the first Bluetooth headset through the second Bluetooth link.

In some embodiments, when the second Bluetooth headset collects a sound signal (second sound signal), it can process the second sound signal to obtain a sound intensity corresponding to the second sound signal as a second sound intensity, and then compare the second sound intensity with a first intensity threshold to obtain a first comparison result, and send the first comparison result to the first Bluetooth headset via the second Bluetooth link.

Step S260: When the first sound intensity is less than or equal to a first intensity threshold and the second sound intensity is greater than the first intensity threshold, sending the switching instruction to the second Bluetooth headset through the second Bluetooth link.

In some embodiments, the preset signal condition may include a first intensity threshold. The first Bluetooth headset may be pre-set and store a first intensity threshold, which is used as a basis for determining the first sound intensity corresponding to the first sound signal collected by the first Bluetooth headset, and as a basis for determining the second sound intensity corresponding to the second sound signal received by the first Bluetooth headset. Therefore, in this embodiment, after obtaining the first sound intensity, the first Bluetooth headset may compare the first sound intensity with the first intensity threshold to determine whether the first sound intensity is less than or equal to the first intensity threshold; after obtaining the second sound intensity, the first Bluetooth headset may compare the second sound intensity with the second intensity threshold to determine whether the second sound intensity is greater than the first intensity threshold.

As a method, when it is determined that the first sound intensity is greater than the first intensity threshold, it indicates that the sound signal collected by the first microphone of the first Bluetooth headset can be normally received by the user, for example, it can meet the normal call requirements in a call scenario. Therefore, the first Bluetooth headset is more suitable as the master headset. At this time, no matter whether the second sound intensity is greater than the first intensity threshold or less than or equal to the first intensity threshold, the master-slave headset switching may not be performed, that is, the first Bluetooth headset can continue to be kept as the master headset, and the second Bluetooth headset can be kept as the slave headset.

As another way, when it is determined that the first sound intensity is less than or equal to the first intensity threshold, and the second sound intensity is less than or equal to the first intensity threshold, it indicates that the sound signal collected by the first microphone of the first Bluetooth headset cannot be normally received by the user, and the sound signal collected by the second microphone of the second Bluetooth headset cannot be normally received by the user. For example, in a call scenario, the sound signal collected by the first Bluetooth headset and the sound signal collected by the second Bluetooth headset cannot meet the normal call requirements. Therefore, it can be considered that the sound input by the user is relatively small, or it can be considered that the first Bluetooth headset and the second Bluetooth headset are not in the wearing state, then the master-slave headset switching can be omitted, that is, the first Bluetooth headset can continue to be kept as the master headset, and the second Bluetooth headset can be kept as the slave headset.

As another way, when it is determined that the first sound intensity is less than or equal to the first intensity threshold, and the second sound intensity is greater than the first intensity threshold, it indicates that the sound signal collected by the first microphone of the first Bluetooth headset cannot be normally received by the user, and the sound signal collected by the second microphone of the second Bluetooth headset can be normally received by the user. For example, in a call scenario, the sound signal collected by the first Bluetooth headset cannot meet the normal call requirements, while the sound signal collected by the second Bluetooth headset meets the normal call requirements. It can be considered that the first Bluetooth headset is more suitable as a slave headset and the second Bluetooth headset is more suitable as a master headset, and the master headset and the slave headset can be switched so that the first Bluetooth headset is switched from the master headset to the slave headset, and the second Bluetooth headset is switched from the slave headset to the master headset.

In this embodiment, when the sound intensity of the sound signal collected by the master earphone is less than or equal to the first intensity threshold, the microphone of the slave earphone is controlled to switch from the sleep state to the working state to collect the sound signal, so as to reduce the power consumption of the slave earphone. In addition, when the signal intensity corresponding to the sound signal collected by the master earphone is less than or equal to the first intensity threshold and the signal intensity corresponding to the sound signal collected by the slave earphone is greater than the first intensity threshold, the master and slave earphones are switched, so that the master earphone can collect the sound signal with the sound intensity meeting the requirement, thereby improving the switching accuracy of the master and slave earphones.

Please refer to FIG4, which shows a schematic flow chart of a method for switching between a master and a slave of a headset provided in an embodiment of the present application. The method is applied to a first Bluetooth headset, when the first Bluetooth headset as a master headset establishes a first Bluetooth link with an electronic device, the second Bluetooth headset as a slave headset establishes a second Bluetooth link with the first Bluetooth headset, the first Bluetooth headset includes a first microphone, and the second Bluetooth headset includes a second microphone. The process shown in FIG4 will be described in detail below, and the method for switching between a master and a slave of a headset may specifically include the following steps:

Step S310: Acquire the sound signal collected by the first microphone as the first sound signal.

Step S320: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

For the detailed description of step S310 to step S320, please refer to step S110 to step S120, which will not be repeated here.

Step S330: obtaining a third sound intensity corresponding to the first sound signal, and obtaining a fourth sound intensity corresponding to the second sound signal.

In some implementations, when the first Bluetooth headset obtains the first sound signal, it may process the first sound signal to obtain the sound intensity corresponding to the first sound signal as the third sound intensity.

As an implementable manner, when obtaining the first sound signal, the first Bluetooth headset may calculate the first sound signal using a preset intensity algorithm to obtain the sound intensity corresponding to the first sound signal as the third sound intensity.

In some embodiments, when the first Bluetooth headset obtains the second sound signal, it can process the second sound signal to obtain the sound intensity corresponding to the second sound signal as the fourth sound intensity. As an implementable manner, when the first Bluetooth headset obtains the second sound signal, it can calculate the second sound signal through a preset intensity algorithm to obtain the sound intensity corresponding to the second sound signal as the fourth sound intensity.

In some embodiments, when the second Bluetooth headset collects a sound signal (second sound signal), it can process the second sound signal to obtain a sound intensity corresponding to the second sound signal as a fourth sound intensity, and send the fourth sound intensity to the first Bluetooth headset through the second Bluetooth link. As an implementable manner, when the second Bluetooth headset collects the second sound signal, it can calculate the second sound signal through a preset intensity algorithm to obtain a sound intensity corresponding to the second sound signal as a fourth sound intensity, and send the fourth sound intensity to the first Bluetooth headset through the second Bluetooth link.

Step S340: When the fourth sound intensity is greater than the third sound intensity, and the difference between the fourth sound intensity and the third sound intensity is greater than a second intensity threshold, a switching instruction is sent to the second Bluetooth headset through the second Bluetooth link, wherein the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as a main headset.

In some embodiments, the preset signal condition may include a second intensity threshold. The first Bluetooth headset may be pre-set and store a second intensity threshold, which is used as a basis for judging the difference between the third intensity threshold corresponding to the first sound signal collected by the first Bluetooth headset and the fourth intensity threshold corresponding to the second sound signal collected by the second Bluetooth headset. Therefore, in this embodiment, after obtaining the third sound intensity and the fourth sound intensity, the first Bluetooth headset may compare the third sound intensity with the fourth sound intensity, and calculate the difference between the fourth sound intensity and the third sound intensity to determine whether the fourth sound intensity is greater than the third sound intensity, and determine whether the difference between the fourth sound intensity and the third sound intensity is greater than the second intensity threshold. The second intensity threshold may, for example, include 5 decibels. Among them, the second intensity threshold can be a dividing line that represents the improvement effect brought about by the switching of master and slave headphones on the collection of sound signals, that is, if the difference between the sound intensity corresponding to the sound signal collected by the slave earphone and the sound intensity corresponding to the sound signal collected by the master earphone is greater than the second intensity threshold, it represents that the improvement effect brought about by the switching of master and slave headphones on the collection of sound signals is obvious; if the difference between the sound intensity corresponding to the sound signal collected by the slave earphone and the sound intensity corresponding to the sound signal collected by the master earphone is less than or equal to the second intensity threshold, it represents that the improvement effect brought about by the switching of master and slave headphones on the collection of sound signals is not good.

As a way, when it is determined that the fourth sound intensity is less than the third intensity threshold, it is characterized that the intensity threshold corresponding to the sound signal collected by the first microphone of the first Bluetooth headset is greater than the intensity threshold corresponding to the sound signal collected by the second microphone of the second Bluetooth headset. Therefore, the first Bluetooth headset is more suitable as the master headset. At this time, regardless of whether the difference between the fourth sound intensity and the third sound intensity is greater than the second intensity threshold, the master-slave headset switching may not be performed, that is, the first Bluetooth headset may continue to be maintained as the master headset, and the second Bluetooth headset may be maintained as the slave headset.

As another way, when it is determined that the fourth sound intensity is greater than the third intensity threshold, and the difference between the fourth sound intensity and the third sound intensity is not greater than the second intensity threshold, it is characterized that although the intensity threshold corresponding to the sound signal collected by the second microphone of the second Bluetooth headset is greater than the intensity threshold corresponding to the sound signal collected by the first microphone of the first Bluetooth headset, that is, the first Bluetooth headset may be farther away from the user than the second Bluetooth headset, but because the difference in sound intensity between the sound signals collected by the two headsets is small, in this case, switching between the master and slave headsets does not significantly improve the collection of sound signals, and will also increase the power consumption of the Bluetooth headset. Therefore, the master and slave headsets may not be switched, that is, the first Bluetooth headset may continue to be kept as the master headset, and the second Bluetooth headset may be kept as the slave headset.

As another way, when it is determined that the fourth sound intensity is greater than the third sound intensity, and the difference between the fourth sound intensity and the third sound intensity is greater than the second intensity threshold, it is characterized that the intensity threshold corresponding to the sound signal collected by the second microphone of the second Bluetooth headset is greater than the intensity threshold corresponding to the sound signal collected by the first microphone of the first Bluetooth headset, that is, the first Bluetooth headset may be farther away from the user than the first Bluetooth headset. At the same time, since the difference in sound intensity between the sound signals collected by the two headsets is large, in this case, switching between the master and slave headsets brings a more obvious improvement in the collection of sound signals. Therefore, it can be considered that the first Bluetooth headset is more suitable as a slave headset and the second Bluetooth headset is more suitable as a master headset, and the switching between the master headset and the slave headset can be performed so that the first Bluetooth headset switches from the master headset to the slave headset, and the second Bluetooth headset switches from the slave headset to the master headset.

In this embodiment, when the sound intensity of the sound signal collected by the slave earphone is greater than the sound intensity of the sound signal collected by the master earphone, and the difference between the sound intensity of the sound signal collected by the slave earphone and the sound intensity of the sound signal collected by the master earphone is greater than the second intensity threshold, the master-slave earphone is switched, so that the master earphone can collect the sound signal with the sound intensity meeting the requirement, thereby improving the switching accuracy of the master-slave earphone.

In some embodiments, it is possible to detect whether the electronic device is in a call state. Wherein, when it is detected that the electronic device is in a call state, it is indicated that the sound signal needs to be collected through the main earphone of the first Bluetooth headset and the second Bluetooth headset, and because the first Bluetooth headset is the main earphone, the first Bluetooth headset can control its first microphone to collect the sound signal. Wherein, when it is detected that the electronic device is not in a call state, it is indicated that the sound signal does not need to be collected through the first Bluetooth headset and the second Bluetooth headset, and the first microphone of the first Bluetooth headset and the second Bluetooth headset can be controlled to be in a dormant state.

As an implementable method, the electronic device can monitor in real time whether a call is in progress and send the monitored information to the first Bluetooth headset, wherein the interface of whether the electronic device is in a call when a call is incoming or outgoing can be monitored, wherein, when it is monitored that the mobile terminal is in a call (CALL_STATE_OFFHOOK), it can be determined that the electronic device is in a call state.

Step S420: Acquire the sound signal collected by the first microphone as the first sound signal.

Step S430: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

Step S440: When the first sound signal and the second sound signal meet a preset signal condition, a switching instruction is sent to the second Bluetooth headset through the second Bluetooth link, wherein the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as a master headset.

For the detailed description of step S420 to step S440, please refer to step S110 to step S130, which will not be repeated here.

In this embodiment, when the electronic device is in a call state, the master-slave switching method of the headset provided in this embodiment is executed, thereby improving the call effect of the electronic device.

Please refer to Figure 6, which shows a schematic flow chart of a master-slave switching method for headphones provided in an embodiment of the present application. The method is applied to a first Bluetooth headset, and when the first Bluetooth headset serves as a master headset and establishes a first Bluetooth link with an electronic device, the second Bluetooth headset serves as a slave headset and establishes a second Bluetooth link with the first Bluetooth headset, and the first Bluetooth headset includes a first microphone, and the second Bluetooth headset includes a second microphone. In this embodiment, the first Bluetooth headset includes a light sensor. The process shown in Figure 6 will be described in detail below, and the master-slave switching method for headphones may specifically include the following steps:

Step S510: determining, based on the light sensor, whether the first Bluetooth headset is in a wearing state.

In this embodiment, the first Bluetooth headset includes a light sensor. The light sensor may include, for example, an ambient light sensor, an infrared light sensor, a sunlight sensor, an ultraviolet light sensor, etc., which are not limited here. The first Bluetooth headset determines whether the first Bluetooth headset is in a wearing state by detecting whether the light sensor is blocked.

In some implementations, the first Bluetooth headset may perform occlusion detection through a light sensor. If the first Bluetooth headset does not detect occlusion through the light sensor, it can be determined that the first Bluetooth headset is not in the ear, that is, the first Bluetooth headset is not in a wearing state, and the master-slave headset switching can be performed, that is, the first Bluetooth headset can be switched from the master headset to the slave headset, and the second Bluetooth headset can be switched from the slave headset to the master headset.

As an implementable manner, when the first Bluetooth headset does not detect occlusion through the light sensor, it can be determined that the first Bluetooth headset is not in the ear, that is, the first Bluetooth headset is not in a wearing state, and then it can be detected whether the second Bluetooth headset is in a wearing state, wherein, when it is detected that the second Bluetooth headset is in a wearing state, the master-slave headset switching can be performed, that is, the first Bluetooth headset can be switched from the master headset to the slave headset, and the second Bluetooth headset can be switched from the slave headset to the master headset. As a manner, the second Bluetooth headset can include a light sensor, and the second Bluetooth headset can detect whether it is in a wearing state through the light sensor included therein. As another manner, the second Bluetooth headset can include a capacitive sensor, and the second Bluetooth headset can detect whether it is in a wearing state through the capacitive sensor included therein. As another manner, the second Bluetooth headset can include a second microphone, and the second Bluetooth headset can detect whether it is in a wearing state through the second microphone.

As an implementable method, when the first Bluetooth headset detects occlusion through the light sensor, it is generally considered that the first Bluetooth headset is in the ear, that is, it is considered that the first Bluetooth headset is in a wearing state. At this time, the switching of the master-slave headset will not be performed, that is, the first Bluetooth headset continues to be kept as the master headset to collect sound signals, and the second Bluetooth headset continues to be kept as the slave headset. However, when the first Bluetooth headset detects occlusion through the sensor, it may also be caused by the first Bluetooth headset being placed somewhere and the light sense is blocked. For example, it may be caused by the first Bluetooth headset being placed on the desktop and the light sense is blocked by the desktop. At this time, although the first Bluetooth headset is detected to be in a wearing state by the light sensor of the first Bluetooth headset, there may still be a possibility of false detection. Therefore, in this embodiment, when it is determined that the first Bluetooth headset is in a wearing state based on the light sensor, it can be obtained and based on the sound signal collected by the microphone of the master headset and the sound signal collected by the microphone of the slave headset, it is determined whether it is necessary to switch the master-slave headset, thereby improving the accuracy of the master-slave headset switching.

Step S520: Acquire the sound signal collected by the first microphone as the first sound signal.

Step S530: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

Step S540: When the first sound signal and the second sound signal meet a preset signal condition, a switching instruction is sent to the second Bluetooth headset through the second Bluetooth link, wherein the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as a master headset.

For the detailed description of step S520 to step S540, please refer to step S110 to step S130, which will not be repeated here.

In this embodiment, when the light sensor determines that the master earphone is in the wearing state, the master-slave switching method of the earphone provided in this embodiment is executed, thereby avoiding false detection of the light sensor and improving the accuracy of the master-slave switching of the earphone.

Please refer to Figure 7, which shows a schematic flow chart of a master-slave switching method for headphones provided in an embodiment of the present application. The method is applied to a first Bluetooth headset, when the first Bluetooth headset serves as a master headset and establishes a first Bluetooth link with an electronic device, the second Bluetooth headset serves as a slave headset and establishes a second Bluetooth link with the first Bluetooth headset, the first Bluetooth headset includes a first microphone, and the second Bluetooth headset includes a second microphone. In this embodiment, the first Bluetooth headset includes a capacitive sensor. The process shown in Figure 7 will be described in detail below, and the master-slave switching method for headphones may specifically include the following steps:

Step S610: determining, based on the capacitive sensor, whether the first Bluetooth headset is in a wearing state.

In this embodiment, the first Bluetooth headset includes a capacitive sensor. The capacitive sensor may include a pressure-type capacitive sensor, for example. The first Bluetooth headset determines whether the first Bluetooth headset is in a wearing state by detecting capacitance through the capacitive sensor provided therein.

In some embodiments, the first Bluetooth headset may detect capacitance through a capacitive sensor. Wherein, when the capacitance detected by the first Bluetooth headset through the capacitive sensor does not meet a preset capacitance, it can be determined that the first Bluetooth headset is not in the ear, that is, the first Bluetooth headset is not in a wearing state, and the master-slave headset switching can be performed, that is, the first Bluetooth headset can be switched from the master headset to the slave headset, and the second Bluetooth headset can be switched from the slave headset to the master headset. Wherein, the preset capacitance can be the capacitance corresponding to when the Bluetooth headset is in the ear.

As an implementable manner, when the first Bluetooth headset detects that the capacitance does not meet the preset capacitance through the capacitive sensor, it can be determined that the first Bluetooth headset is not in the ear, that is, the first Bluetooth headset is not in the wearing state, and then the second Bluetooth headset can be detected whether it is in the wearing state, wherein, when the second Bluetooth headset is detected to be in the wearing state, the master-slave headset switching can be performed, that is, the first Bluetooth headset can be switched from the master headset to the slave headset, and the second Bluetooth headset can be switched from the slave headset to the master headset. As a manner, the second Bluetooth headset can include a light sensor, and the second Bluetooth headset can detect whether it is in the wearing state through the light sensor included therein. As another manner, the second Bluetooth headset can include a capacitive sensor, and the second Bluetooth headset can detect whether it is in the wearing state through the capacitive sensor included therein. As another manner, the second Bluetooth headset can include a second microphone, and the second Bluetooth headset can detect whether it is in the wearing state through the second microphone.

As an implementable method, when the first Bluetooth headset detects that the capacitance meets the preset capacitance through the capacitive sensor, it is generally considered that the first Bluetooth headset is in the ear, that is, it is considered that the first Bluetooth headset is in a wearing state. At this time, the switching of the master-slave headset will not be performed, that is, the first Bluetooth headset continues to be kept as the master headset to collect sound signals, and the second Bluetooth headset continues to be kept as the slave headset. However, when the first Bluetooth headset detects that the capacitance meets the preset capacitance through the sensor, it may also be caused by the position of the capacitive sensor of the first Bluetooth headset held by the user. At this time, although the first Bluetooth headset is detected to be in a wearing state through the capacitive sensor of the first Bluetooth headset, there may still be the possibility of false detection. Therefore, in this embodiment, when it is determined that the first Bluetooth headset is in a wearing state based on the capacitive sensor, it can be obtained and based on the sound signal collected by the microphone of the master headset and the sound signal collected by the microphone of the slave headset, it is determined whether the master-slave headset needs to be switched, thereby improving the accuracy of the master-slave headset switching.

Step S620: Acquire the sound signal collected by the first microphone as the first sound signal.

Step S630: Acquire the sound signal collected by the second microphone through the second Bluetooth link as the second sound signal.

Step S640: When the first sound signal and the second sound signal meet a preset signal condition, a switching instruction is sent to the second Bluetooth headset through the second Bluetooth link, wherein the switching instruction is used to instruct the second Bluetooth headset to establish a Bluetooth link with the electronic device as a master headset.

For the detailed description of step S620 to step S640, please refer to step S110 to step S130, which will not be repeated here.

In this embodiment, when the capacitive sensor determines that the master earphone is in the wearing state, the master-slave switching method of the earphone provided in this embodiment is executed, thereby avoiding false detection of the capacitive sensor and improving the accuracy of the master-slave switching of the earphone.

In this embodiment, when the sound intensity of the sound signal collected by the master earphone is less than or equal to the first intensity threshold, the microphone of the slave earphone is controlled to switch from the dormant state to the working state to collect the sound signal, so as to reduce the power consumption of the slave earphone. In addition, when the signal intensity corresponding to the sound signal collected by the master earphone is less than or equal to the first intensity threshold and the signal intensity corresponding to the sound signal collected by the slave earphone is greater than the first intensity threshold, the master and slave earphones are switched, so that the sound signal with the sound intensity meeting the requirement can be collected by the master earphone, and the switching accuracy of the master and slave earphones is improved. Furthermore, when the signal intensity corresponding to the sound signal collected by the master and slave earphones is less than or equal to the first intensity threshold, the difference between the signal intensity corresponding to the sound signal collected by the slave earphone and the signal intensity corresponding to the sound signal collected by the master earphone is compared with the second intensity threshold, and when the difference between the signal intensity corresponding to the sound signal collected by the slave earphone and the signal intensity corresponding to the sound signal collected by the master earphone is greater than the second intensity threshold, and the signal intensity corresponding to the sound signal collected by the slave earphone is greater than the signal intensity corresponding to the sound signal collected by the master earphone, the master and slave earphones are switched, so that the sound signal with the sound intensity meeting the requirement can be collected by the master earphone, and the switching accuracy of the master and slave earphones is improved.
