As used in this specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural referents unless the context clearly dictates otherwise.

It should also be further understood that the term "and/or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations .

As used in this specification and the appended claims, the term "if" may be construed as "when" or "once" or "in response to determining" or "in response to detecting" depending on the context . Similarly, the phrase "if determined" or "if [the described condition or event] is detected" may be construed, depending on the context, to mean "once determined" or "in response to the determination" or "once detected [the described condition or event] ]” or “in response to detection of [described condition or event]”.

Currently, for a dual-connection wireless Bluetooth headset, wireless communication connections can be established with two or more devices at the same time. However, due to the connection-back mechanism, after the headset is unpacked, it is necessary to make a connection-back judgment to the device that was connected last time. As shown in (a) of Figure 1, mobile phone A and mobile phone B are examples of dual-connected electronic devices. Within the connection range, when the earphone is opened, it will send back connection requests to mobile phone A and mobile phone B respectively based on the fixed connection sequence in the back connection mechanism. According to the request, after the mobile phone B reports that the connection is successful, the communication channel between the headset and mobile phone A and mobile phone B officially starts to work.

However, as shown in (b) of Figure 1, a scenario where the status of the mobile phone is determined and does not connect back first. When the state of one of the electronic devices (such as mobile phone A) is uncertain, such as mobile phone A is not within the connectable range of the headset or the Bluetooth is turned off, after the headset is unpacked, it still needs to be based on the connection sequence of the original fixed connection mechanism , first initiate a connection back request to mobile phone A, and wait for the feedback to time out before ending the connection back process to mobile phone A; only when the connection back to mobile phone A fails will it initiate a connection back request to mobile phone B, and then After the mobile phone B reports that the connection is successful, it starts to work based on the communication channel with the mobile phone B. Due to the long waiting time in the judgment process of mobile phone A with an uncertain state, the connection time between the headset and mobile phone B is too long, which makes the response of the headset and electronic equipment slow, which affects the user experience.

Moreover, as shown in (c) in Figure 1, a mobile phone status is determined and the scene is connected back first. When the status of mobile phone B is uncertain, for example, mobile phone B is not within the connectable range of the headset or the Bluetooth of mobile phone B is turned off, after the headset is opened, it will successfully reconnect with mobile phone A based on the fixed connection sequence in the original connection mechanism. Finally, initiate a connection back request to mobile phone B. Since the status of mobile phone B is uncertain, it is determined that mobile phone B has failed to connect back after waiting for a timeout, and it will start working based on the communication connection between mobile phone A and the headset after it is determined that mobile phone B has failed to connect back. , making it take a long time to respond to the work after the earphone is connected back to the electronic device, and the response efficiency is low, which also affects the user experience.

In view of the above defects, the present application provides an earphone reconnection system, which can shorten the reconnection time between the earphone and the electronic device, and improve the efficiency of the reconnection between the earphone and the electronic device and the work response efficiency.

Please refer to FIG. 2 . FIG. 2 is a structural diagram of an earphone connection system provided by an embodiment of the present application. As shown in FIG. 2 , the system may include a first electronic device 10 , an earphone 20 and a second electronic device 30 .

Exemplarily, in some application scenarios, the system may only include one electronic device and an earphone, such as the first electronic device 10 and the earphone 20, or the second electronic device 30 and the earphone.

As shown in FIG. 2 , if the first electronic device 10 and the second electronic device 30 are in a connectable state, the headset 20 can respectively establish a communication connection with the first electronic device 10 and the second electronic device 30 after unpacking. In order to improve the efficiency of establishing a connection back between the earphone 20 and the electronic device, in the embodiment of the present application, when the earphone is closed, the target broadcast signal sent by the electronic device can be scanned to determine the connectable device within the connection range, and when the box is opened Quickly initiate a connection request to a connectable device. Alternatively, when the electronic device is disconnected from the earphone, the earphone can send a target broadcast signal of Bluetooth Low Energy in the closed state, and the electronic device can actively initiate a response to the earphone when the earphone is opened based on the scanned target broadcast signal. connection request to establish a communication connection.

Exemplarily, the target broadcast signal is a broadcast signal that the electronic device and the earphone have known and can identify and respond to. For example, the target broadcast signal may contain an encryption protocol agreed upon by the earphone and the electronic device. Generated when the pairing connection is established for the first time. After the headset is unpacked, communication connections can be established with the first electronic device and the second electronic device respectively, as shown in Figure 2, the connection status of the connected headset can also be displayed on the display interface of the first electronic device and the second electronic device and battery status information.

Exemplarily, the electronic device establishing a wireless communication connection with the earphone may be a terminal capable of wireless communication such as a mobile phone, a tablet, and a notebook computer, and the type of the electronic device is not limited here.

It should be noted that the above-mentioned target broadcast signal based on low-power Bluetooth broadcast, scanning and identification of the target broadcast signal, and the process of connecting back can be applied to the scene where a single electronic device establishes a connection back with the headset, or can be applied to two or more The scene where multiple devices establish a connection back with the earphone; based on the above connection back mechanism, it can improve the defect that the original connection back mechanism has too long waiting time due to the uncertain state of the electronic device based on the fixed connection sequence, and improves the connection between the earphone and the headset. The speed of the connection back of the electronic device; there is no need to wait for the connection back judgment of other electronic devices in an uncertain state, so that the headset can quickly enter the business state.

Aiming at the scene where the earphone and the electronic device have already established a pairing connection, and the communication connection is disconnected and reconnects again, the implementation process of quickly establishing a reconnection between the earphone and the electronic device will be introduced in detail through specific embodiments below. The mobile phone B is the first electronic device, and the mobile phone A is the second electronic device.

Firstly, the earphone is used as the scanning end, and the electronic device is used as the broadcasting end, so that the earphone and the electronic device are connected back.

Embodiment one

As shown in FIG. 3 , the earphone connection system includes an earphone and a first electronic device (the mobile phone B is taken as an example for description below). Wherein, after the mobile phone B is disconnected from the earphone, it sends out the first target broadcast signal with the first broadcast frequency, for example, sends a first target broadcast signal of Bluetooth Low Energy every 10 seconds. When the earphone is in the closed state, it wakes up regularly at the first scanning frequency, and continuously scans the target broadcast signal for a certain period of time; for example, when the earphone is in the closed state, it wakes up every 20 minutes and scans for 15 seconds.

Exemplarily, the above-mentioned first target broadcast signal may be an encrypted broadcast including an encryption protocol. The encryption protocol may be generated by agreement when the headset and the electronic device are paired and connected for the first time; the first target broadcast signal may include identification information of the electronic device that sends out the broadcast, such as the model or name of mobile phone B, and the like.

In some embodiments, after the earphone scans the first target broadcast signal in the closed state, it can be determined that the mobile phone B is within a connectable range and is in a connectable state. When the earphone is unpacked, it can first send a communication connection signal to the mobile phone B based on the scanned first target broadcast signal, initiate a connection back request to the mobile phone B, and establish a communication connection with the mobile phone B.

Exemplarily, when the earphone is in the closed state and the first electronic device is disconnected from the earphone, it can enter the Bluetooth low energy working state, for example, when the earphone is in the closed state The device enters the signal broadcast state of Bluetooth low energy when it is disconnected from the headset.

Exemplarily, the first electronic device may be a wireless communication terminal such as a mobile phone, a tablet computer, or a notebook computer. The first broadcast frequency of the first electronic device can be set based on the user's usage time period habits, for example, the low-power broadcast is turned on during the day and turned off at night; or different broadcast frequencies are set for different time periods during the day.

In a possible implementation, the above connection-back mechanism is also applicable to mobile phone A, that is, the first electronic device may also be the electronic device that ranks first in the connection sequence in the historical connection information, and the earphone scans when the mobile phone A is in the closed state. After opening the box, it will first establish a connection back with mobile phone A after opening the box; and when the target broadcast signal of mobile phone B is not scanned, it will not try to connect back to mobile phone B after successfully establishing a connection with mobile phone A , after the successful reconnection with mobile phone A, it will directly enter the working state, and there is no need to judge the reconnection with mobile phone B again. That is, regardless of whether the device to be connected currently scanned by the headset is the first or last electronic device in the original inherent connection sequence, when the headset is closed and only scans the target broadcast signal of one electronic device, it will only be prioritized and only connected to the scanned The one electronic device establishes a connection back, and after the connection back is successful, the connection back status of the other electronic device is no longer judged. As shown in Figure 7, on the headset setting display interface of the electronic device (mobile phone B), only the device connected to the headset is displayed on the dual-device connection control interface; or as shown in Figure 8, the headset has been established with multiple electronic devices For the first connection of pairing, you can only highlight one of your own devices (mobile phone B) that has established a communication connection with the headset when you connect back, and you can also display other connected devices (mobile phone A and tablet iPad), but you can pass the grayscale The display indicates that other connected devices (mobile phone A and tablet iPad) are currently not connected.

Through the above method, after the headset is disconnected from the electronic device, the headset scans the target broadcast signal sent by mobile phone B in the closed state, and the status of mobile phone B can be determined based on the target broadcast signal, and then the mobile phone B can be sent to mobile phone B in time after the box is opened. When initiating a connection back request, there is no need to confirm whether mobile phone B is the first connection order based on the order of connection with other electronic devices in the historical connection information, and there is no need to wait for the time to judge the connection back with other electronic devices in the historical connection information. When only one electronic device is in the connectable range and in a connectable state, the connection speed of the dual-connection headset can be greatly improved, and after the connection is established, it can immediately enter the working state without waiting for the time to connect back to other electronic devices, etc. , to improve the response efficiency of the headset entering the business state after the connection is established.

Embodiment two

As shown in Figure 4, the earphone connection system may also include an earphone, a first electronic device, and a second electronic device; wherein, after the second electronic device is disconnected from the earphone, it may also send a low-power bluetooth signal, that is, the first Two target broadcast signals, the second target broadcast signal may include the second encryption protocol and the device identification of the second electronic device, such as device model or name and other information. In the following, the mobile phone B as the first electronic device and the mobile phone A as the second electronic device are used as an example for illustration.

Exemplarily, mobile phone B sends a first target broadcast signal with a first broadcast frequency, and mobile phone A sends a second target broadcast signal with a second broadcast frequency; the first broadcast frequency and the second broadcast frequency may be the same broadcast frequency, or may be are different broadcasting frequencies; the earphone scans the target broadcasting signal at the first scanning frequency in the closed state.

As shown in Figure 4, in the current certain period of time, the solid line corresponding to mobile phone B represents the target broadcast signal sent within the scannable range of the earphone; the dotted line part corresponding to mobile phone A is not sent within the scannable range of the earphone The target broadcast signal, the solid line part corresponds to the target broadcast signal sent within the scannable range of the earphone, that is, the solid line part corresponds to the target broadcast signal that the earphone can scan in the closed state, and the dotted line part corresponds to the target broadcast signal that the earphone cannot scan target broadcast signal.

In a possible implementation manner, during the scanning process of the earphone in the closed state, the time node when the target signal is scanned for the first time may also be recorded, or the number or frequency of the target signal scanned is recorded by a counter. For example, within a certain period of time, the headset can record the time node of mobile phone B scanned for the first time in the off-box state, and determine based on this time node to initiate a connection back request to mobile phone B after opening the box; or record the time node scanned during the scanning process. The number or frequency of the target broadcast signal, for example, mobile phone B is always within the scannable range of the earphone, then you can count 5 target broadcast signals sent by mobile phone B, while mobile phone A is not always within the scannable range of the earphone, the earphone The target broadcast signal sent by mobile phone A may only be scanned twice; based on the number of scanned target broadcast signals, it is determined that mobile phone B is a device to be connected in a stable state. Mobile phone B first sends out a communication connection signal, establishes a connection back with mobile phone B first, and then initiates a connection back request to mobile phone A to establish a communication connection with mobile phone A after the connection is successful.

Exemplarily, the headset can also set a threshold for the number of times the target broadcast signal is scanned. When the threshold is not reached, even if the corresponding target broadcast signal is scanned in the off-box state, no reconnection is performed; as shown in Figure 4, If the headset only scans the target broadcast signal of mobile phone A once, and the number of times does not reach the threshold, it is possible that mobile phone A only appears in the connectable range of the headset and then leaves the scene, so it is only based on the scanned target broadcast from mobile phone B The signal is prioritized and only establishes a connection with mobile phone B; thereby ensuring the timeliness of the connection and at the same time ensuring the reliability of the connection, reducing the probability of invalid connection and the time-consuming caused by invalid connection.

Exemplarily, when the headset is unpacked, it sends a communication connection signal to the first electronic device based on scanning the first target broadcast signal, or sends a communication connection signal to the second electronic device based on the scanned second target broadcast signal, respectively. The first electronic device or the second electronic device establishes a communication connection. When the headset has established a pairing connection with multiple electronic devices, and the first electronic device and the second electronic device are two of the multiple electronic devices, when the headset scans the first target broadcast signal or the second target broadcast signal, it can Establish a return connection with only one of the two electronic devices, or establish a return connection with two electronic devices based on the status of the scanned target signal.

As shown in Figure 8, on the headset setting display interface of the electronic device (mobile phone B), the dual-device connection control interface, by highlighting two devices connected to the headset (mobile phone A and mobile phone B, mobile phone B is the priority connection) , and other connected devices can also be displayed at the same time, but the grayscale display indicates that other connected devices are currently not connected, as shown in FIG. 8 , the tablet iPad.

It should be noted that after the headset is successfully connected back to the electronic device, the headset can clear the information such as the time node or the number of times of scanning recorded during the connection back; or after a connection ends, that is, the headset is disconnected from the electronic device After returning to the off-box state, the headset can clear the time node or the number of scanned times recorded during the last connection back; and start recording again when the target broadcast signal is scanned in the next off-box state.

Through the above method, the headset does not need to establish a connection back with the electronic device that can be connected based on the inherent connection order in the historical connection information. The status of the scanned target broadcast signal determines the electronic device that is connected with priority, and improves the timeliness and reliability of the connection between the earphone and the electronic device.

Based on the implementation of the first and second embodiments above, the earphone is used as the scanning end, and wakes up regularly at the first scanning frequency to scan for a period of time. If the target broadcast signal is not scanned at the first scanning frequency, then reduce the scanning frequency, or The duration of one scan is shortened, and the scan is continued with the second scan frequency after the frequency is reduced or the scan time period of one scan is shortened, so as to save the power consumption of the earphone.

Then introduce the earphone as the broadcasting end, and the electronic device as the scanning end, so that the earphone and the electronic device realize the process of connecting back.

Embodiment three

As shown in FIG. 5 , the earphone connection system includes an earphone and a first electronic device (hereinafter, a mobile phone B is taken as an example for description). Wherein, the headset is in the closed state, and sends the first target broadcast signal with the third broadcast frequency, for example, sending a first target broadcast signal of Bluetooth low power consumption every 10 seconds; the target broadcast signal may contain the device identification of the headset, for example Information such as the model or name of the headset. After the mobile phone B is disconnected from the earphone, it wakes up the scanning mechanism regularly at the third scanning frequency, and continuously scans broadcast signals for a certain period of time; for example, when the first electronic device is disconnected from the earphone, it wakes up the scanning mechanism every 20 minutes and scans for 15 Second.

Exemplarily, when the mobile phone B scans the target broadcast signal of the earphone at the third scanning frequency, increase the scanning frequency, wake up the scanning mechanism regularly at the fourth scanning frequency, and continue scanning. Mobile phone B can quickly scan the unboxing broadcast signal, discover the unpacking status of the earphone in time, actively send a communication connection signal to the earphone, initiate a connection back request to the earphone, and after the communication connection is established, the earphone will report back to mobile phone B successfully. Information, and then start to enter the business state.

In a possible implementation manner, the earphone sends out a third target broadcast signal containing a third encryption protocol at a third broadcast frequency in the closed state; after the first electronic device scans the third target broadcast signal, based on the third The encryption protocol sends a communication connection signal to the earphone to establish a communication connection with the earphone when an open-box broadcast signal is scanned.

Exemplarily, the same as Embodiment 1 and Embodiment 2, the target broadcast signal broadcast by the headset is also an encrypted broadcast signal containing an encryption protocol, and the electronic device can determine that the headset is within a connectable range after scanning the target broadcast signal and increase the scanning frequency to timely discover the unpacking broadcast signal sent by the headset when it is unpacked, and quickly and proactively establish a connection with the headset.

Exemplarily, the third encryption protocol included in the third target broadcast signal may be an encryption protocol generated when the headset and the electronic device are paired and connected for the first time, that is, the headset may broadcast the third target broadcast signal containing the third encryption protocol, thereby The first electronic device can distinguish other scanned broadcast signals, and only after scanning the third target broadcast signal containing the third encryption protocol, the first electronic device determines that the earphones that can be connected are nearby, and after the earphones are unpacked, Respond based on the scanned open-box broadcast signal, and actively initiate a connection back to the headset.

It should be noted that when the mobile phone A is in the scanning state, the implementation principle is the same as that of the mobile phone B, that is, the above connection mechanism is also applicable to the mobile phone A. The first electronic device may also be the electronic device with the highest connection order in the historical connection information. After the mobile phone A scans the target broadcast signal sent by the earphone in the closed state, it increases the scanning frequency, and scans the open-box broadcast signal of the earphone. After that, take the initiative to establish a connection back with the headset; and when the target broadcast signal of mobile phone B is not scanned, after the connection between mobile phone A and the headset is successfully established, the headset will not try to connect back to mobile phone B again. After the connection is successful, it will directly enter the working state, and there is no need to judge the connection with mobile phone B again; since mobile phone B does not participate in the scanning process, mobile phone B will not initiate a connection request; shortening the connection between the earphone and the electronic device The connection time is improved, and the efficiency of the connection between the earphone and the electronic device is improved. That is to say, regardless of whether the electronic device performing the scanning action is the first or the last electronic device in the original intrinsic connection sequence, when there is only one electronic device that scans the target broadcast signal when the headset is closed, only this one electronic device can actively send the broadcast signal to the target broadcast signal. The headset initiates a connection-back request, and after the connection-back is successful, it enters the business state without judging the connection-back status of another electronic device. As shown in Figure 7, on the headset setting display interface of the electronic device (mobile phone B), only the device connected to the headset is displayed on the dual-device connection control interface; or as shown in Figure 8, the headset has been established with multiple electronic devices For the first connection of pairing, you can only highlight one of your own devices (mobile phone B) that has established a communication connection with the headset when you connect back, and you can also display other connected devices (mobile phone A and tablet iPad), but you can pass the grayscale The display indicates that other connected devices (mobile phone A and tablet iPad) are currently not connected.

Through the above method, after the first electronic device scans the third target broadcast signal of the earphone based on the third scanning frequency, it increases the scanning frequency and continues to scan at the fourth scanning frequency, so that when the earphone is unpacked, it can be scanned in a more timely manner. When the headset is opened, the broadcast signal is sent, and the communication connection signal is sent to the headset in time, and the connection with the headset is quickly established, without the need to judge the dual-connection device for each connection and increase the connection time.

Embodiment Four

As shown in Figure 6, the earphone connection system may also include an earphone, a first electronic device, and a second electronic device; wherein, after the second electronic device is disconnected from the earphone, it may also scan the earphone when the earphone is turned off based on low-power bluetooth. The target broadcast signal sent by the box state, the target broadcast signal may contain the encryption protocol and the device identification of the headset, such as the model or name of the headset and other information. In the following, the mobile phone B as the first electronic device and the mobile phone A as the second electronic device are used as an example for illustration.

In a possible implementation, the headset is in the closed state, and sends out a third target broadcast signal containing the desired connection sequence at a third broadcast frequency; when the first electronic device and the second electronic device scan the third target broadcast signal, And after the earphones are unpacked, a communication connection signal is sent to the earphones based on the desired connection sequence, and communication connections are respectively established with the earphones.

Exemplarily, for dual-connection earphones, the above-mentioned third target broadcast signal including the third encryption protocol may also carry the expected connection order of the earphones, and the expected connection order may be set based on the user's time habit or scene of using the earphones, For example, when the headset and the electronic device are paired and connected for the first time or when the electronic device and the headset are connected, the desired connection sequence of the headset can be set based on the electronic device, so that the headset receives the information of the desired connection sequence transmitted by the electronic device, And set according to the corresponding time or scene; so that when the box is closed, the earphone can send out the target broadcast signal with the desired connection sequence based on the corresponding time or scene.

Exemplarily, after the electronic device scans the target broadcast signal broadcast by the earphone, it can also identify the expected connection sequence in the target broadcast signal, and establish a connection back with the earphone based on the expected connection sequence after scanning the open-box broadcast signal .

Exemplarily, the expected connection sequence may include the identifiers of one or two devices to be connected.

As shown in Figure 6, in the first case, when the expected connection sequence contains an identifier of a device to be connected, after the electronic device corresponding to the identifier scans the target broadcast signal, it quickly establishes a connection with the earphone based on the expected connection sequence Connect back, the headset no longer waits for another electronic device to connect back, but directly enters the working state with the electronic device that has been successfully connected back; thus improving the efficiency of the connection between the headset and the electronic device.

As shown in Figure 6, in the second case, when the expected connection sequence contains the identifications of two devices to be connected, the identifications of the two devices to be connected have serial numbers used to indicate successive connections; when the electronic device scans the target After broadcasting the signal and identifying the sequence numbers of successive connections in the target broadcast signal, establish a connection back to the earphones based on the sequence numbers in the expected connection sequence; after receiving the unpacking broadcast signal, the electronic device with the first serial number broadcasts The expected connection order in the signal prioritizes the initiative to initiate a connection back to the headset.

Exemplarily, if the mobile phone B is the first to establish a communication connection in the desired connection sequence, after scanning the broadcast signal of the headset opening box, the mobile phone B actively reconnects the headset based on the desired connection sequence, and receives feedback from the headset that the connection is successful. At the same time, the earphone will initiate a connection back to mobile phone A, and start to enter the business state after receiving the information of successful connection back from mobile phone A; When the connection back is successful, mobile phone A initiates a connection back request to the headset, and after the connection is successfully established, the headset feeds back the connection success information to mobile phone A and enters the business state.

It should be noted that the fourth embodiment above only represents a possible dual-connection application scenario; it is aimed at the reconnection mechanism when the desired connection sequence is stored in the headset and the low-power Bluetooth broadcast is sent out in the closed state. The expected connection sequence in the connection-back mechanism can be set and stored based on usage time or application scenarios when the electronic device is connected to the earphone. For example, when driving to work in the morning, only the earphone and an electronic device (such as mobile phone B ) connection, based on the above connection mechanism, the target broadcast signal with the expected connection sequence sent by the earphone may only contain the device identification information of mobile phone B; if the user returns home from get off work at night, the user may need to connect to the tablet at the same time when using the earphone For two electronic devices, the mobile phone and the mobile phone, the target broadcast signal with the expected connection order sent by the earphone can contain the device identification of the mobile phone and the tablet and sort them, for example, the mobile phone is connected first, and the tablet is connected after; the corresponding time period can be based on the above The connection mechanism quickly realizes the connection between the earphone and the electronic device.

Through the above method, it is not necessary to judge the dual-device connection status every time the headset is connected back to the electronic device, and the expected connection sequence of the headset connection can be preset in advance, and the headset and the electronic device can be quickly connected in a suitable application scenario or time period. Reconnection reduces the probability of invalid reconnection, improves the efficiency of reconnection between earphones and devices, and improves user experience.
