When user 1 wishes to use the TWS earphone to make a call, he can open the cover of the earphone box of the TWS earphone. The left and right earbuds of the TWS earbuds are turned on automatically, or turned on after the function key is pressed. If the Bluetooth pairing between the left earbud and the right earbud has not been completed before, the left earbud and the right earbud can automatically perform Bluetooth pairing, or the left earbud and the right earbud can perform Bluetooth pairing after the pairing function key is pressed. If the Bluetooth pairing of the left earbud and the right earbud has been completed before, the Bluetooth pairing process can be omitted. After the Bluetooth pairing is completed, a control link 1 can be established between the left earbud and the right earbud using Bluetooth. Wherein, the control link 1 may be the first control link in this application.

Among the left and right earplugs of the TWS earphone, the earplug (such as the right earplug) serving as the main earplug establishes a control link 2 with the mobile phone 1 .

Among them, any of the left and right earplugs of the TWS headset can be used as the main earplug. In some embodiments, the earplug that is taken out of the earphone box among the left and right earplugs can be used as the main earplug, and the other earplug can be used as the secondary earplug. Alternatively, the left and right earplugs include a pairing function key, the earplug whose pairing function key is pressed first can be used as the main earplug, and the other earplug can be used as the secondary earplug. Alternatively, the earplug that is worn on the ear first among the left and right earplugs can be used as the main earplug, and the other earplug can be used as the secondary earplug. Or, which of the left and right earplugs is the main earplug and which earplug is the secondary earplug is pre-defined. For example, when the TWS headset leaves the factory, one of the left and right earplugs is configured as the primary earplug, and the other earplug is the secondary earplug. Wherein, the main earplug may be the first earplug in this application, and the secondary earplug may be the second earplug in this application.

Take determining the primary and secondary earplugs according to the order in which they are worn on the ears as an example. Exemplarily, the right earbud of the TWS earphone is first worn by user 1 on the ear. For example, a proximity light sensor is included in the right earbud. When the right earplug is worn on the ear, the right earplug can use the proximity light sensor to detect that there is an object near the right earplug, thereby determining that the right earplug is worn by the user. After it is determined to be worn, the right earbud can serve as the main earbud of the TWS headset and send a pairing broadcast to the outside world. If the mobile phone 1 has turned on the Bluetooth function, the mobile phone 1 can receive the pairing broadcast and prompt the user that a related Bluetooth device (such as a TWS earphone) has been scanned. When the TWS headset on mobile phone 1 is selected as the connection device, mobile phone 1 can perform Bluetooth pairing with the right earbud as the main earbud. After the Bluetooth pairing is completed, the mobile phone 1 can establish a control link 2 with the right earbud as the main earbud using Bluetooth. Of course, if the Bluetooth pairing between the mobile phone 1 and the right earbud of the TWS headset has been completed before, the Bluetooth pairing process can be omitted. That is to say, after receiving the above-mentioned pairing broadcast, the mobile phone 1 can automatically establish a control link 2 with the right earbud as the main earbud by using Bluetooth. Wherein, the control link 2 may be the second control link in this application.

In the embodiment of this application, the control link 1 established between the left and right earbuds of the TWS headset, and the control link 2 established between the right earplug as the main earbud and the mobile phone 1, are used to transmit control data (such as answering call, hang up, etc.). To realize the transmission of voice data during a call, Bluetooth is also required to establish a voice link between the left and right earbuds of the TWS headset, and between the right earbud as the main earbud and the mobile phone 1 . In some embodiments, the voice link between the left and right earbuds (such as called voice link 1, voice link 1 can be the first voice link in this application), can be established after the confirmation of the primary and secondary earplugs , can also be established when there is a voice service (such as receiving an incoming call, receiving an operation of answering a call, or receiving an operation of making a call). The voice link between the right earbud as the main earplug and the mobile phone 1 (such as called voice link 2, which can be the second voice link in this application), can be the mobile phone 1 and the mobile phone 1 as the main earplug. It can be established after the Bluetooth pairing of the right earbud is completed, or it can be established when there is a voice service.

In some embodiments, among the left and right earplugs of the TWS earphone, the earplug that is the main earplug can also turn on the microphone of the earplug for sound signal collection. Exemplarily, after the right earbud is determined to be worn, the right earbud may also turn on the microphone of the right earbud. When the right earplug is used as the main earplug of the TWS headset, the left earplug is used as the secondary earplug of the TWS headset.

In addition, since the TWS earphone is used as a pair of binaural earphones to realize the call, the left and right earplugs of the TWS earphone are usually used by one user (such as user 1), that is, only the sound signal of one user needs to be collected. Therefore, among the left and right earplugs of the TWS earphone, only the microphone of the earplug that is the main earplug is turned on, and the microphone of the earplug that is the secondary earplug may not be turned on. For example, the microphone of the right earbud serving as the main earbud is turned on, and the microphone of the left earbud serving as the secondary earbud is not turned on. In some embodiments, the right earplug can notify the left earplug as the secondary earplug through the above-mentioned control link 1 that the right earplug is the main earplug of the TWS earphone. In this way, even if the left earbud is worn on the ear, the left earbud will not turn on the microphone of the left earbud.

When wanting to implement a multi-person conference call, for example, when user 3 wants to access a call through mobile phone 1, one of the left and right earplugs of the TWS headset can be shared with user 3 for use. That is to say, user 1 and user 3 can respectively use the left and right earbuds in the TWS headset to make a call. In the process of multiple people conducting a conference call, there is not only a demand for collecting the voice signal of user 1, but also a demand for collecting the voice signal of user 3. Therefore, it is not only necessary to turn on the microphone of the earplug as the main earplug in the TWS earphone, but also the microphone of the earplug as the secondary earplug. In the embodiment of the present application, the user can perform the first operation to turn on the microphones of the earplugs serving as the pair of earplugs, so that the microphones of the left and right earplugs of the TWS earphone are all turned on.

For example, if the left earplug serving as a pair of earplugs is not worn, user 1 will usually share the left earplug with user 3 for use. After the user performs the first operation, the left earplug as a pair of earplugs can turn on the microphone of the left earplug, so that the microphones of the left and right earplugs of the TWS earphone are all turned on.

For another example, if the left earbud as a pair of earbuds is worn by user 1, user 1 may share the right or left earbud of the TWS headset with user 3 for use.

If user 1 wants to share the left earbud as a pair of earbuds with user 3, after the user performs the first operation, the left earbud as a pair of earbuds can turn on the microphone of the left earbud, so that the microphones of the left and right earbuds of the TWS headset are all on state.

If user 1 wants to share the right earplug as the main earplug with user 3, the user first removes the right earplug from the ear, and then performs the first operation. Then, when user 1 removes the right earplug from the ear, the right earplug The earbuds can detect that the right earbud has changed from being worn to not being worn. At this time, the left and right earbuds can switch roles. After the primary and secondary roles are swapped, the left earbud acts as the primary earplug of the TWS headset, and the right earplug acts as the secondary earplug of the TWS headset. And, the right earbud as the auxiliary earbud needs to turn off the microphone of the right earbud, and the left earbud as the main earbud needs to turn on the microphone of the left earbud. Then, after the user performs the first operation, the right earplug as the auxiliary earplug can turn on the microphone of the right earplug, so that the microphones of the left and right earplugs of the TWS earphone are all turned on.

If user 1 wants to share the right earplug as the primary earplug with user 3, the user first performs the first operation, and then removes the right earplug from the ear. Then, after the user performs the first operation, the left earplug as the secondary earplug You can turn on the microphone of the left earbud so that the microphones of the left and right earbuds of the TWS headset are all on. Then, when the user 1 removes the right earplug from the ear, the right earplug can detect that the right earplug has changed from being worn to not being worn, and at this time, the left and right earplugs can switch roles of the primary and secondary roles. After the primary and secondary roles are swapped, the left earbud will be the primary earplug of the TWS headset, and the right earplug will be the secondary earplug of the TWS headset. In some embodiments, when the user 1 takes the right earbud off the ear, the left and right earbuds may not be switched between the primary and secondary roles.

In some embodiments, when the right earbud as the master earbud detects that the right earbud is changed from being worn to not being worn, the specific process for the role exchange of the left and right earbuds may be: the right earbud currently serving as the master earbud transmits status information to left earplug. The status information may include the Bluetooth address (such as MAC address) of the TWS earphone. This status information can be used to instruct the left earbud to use the Bluetooth address of the TWS earphone instead of the right earbud as the main earbud, and take over the Bluetooth connection between the right earbud and the mobile phone 1 (ie control link 2).

In addition, in the embodiment of the present application, if only the microphone of the earplug as the primary earplug is turned on among the left and right earplugs of the TWS earphone, then only the primary earplug needs to send voice data to the secondary earplug during a call. Therefore, the above voice link 1 may be a one-way voice link from the primary earbud to the secondary earbud. And if the microphones of the left and right earbuds of the TWS headset are turned on, during a call, not only the main earbuds will need to send voice data to the secondary earbuds, but also the secondary earbuds will need to send voice data to the main earbuds. Therefore, the above-mentioned voice link 1 can be a two-way voice link from the main earbud to the auxiliary earbud, and from the auxiliary earbud to the main earbud. In some embodiments, Bluetooth is used to establish a voice link 1 between the left and right earplugs. Specifically, it can be: after the main and secondary earplugs are confirmed or when there is a voice service or after Bluetooth pairing is completed, a two-way voice link is established using Bluetooth. . In some embodiments, the two-way voice link may be a Bluetooth synchronous connection-oriented/extended synchronous connection-oriented (synchronous connection-oriented/extended SCO, SCO/eSCO) voice link, and the voice link is configured as a two-way link road. Or, between the left and right earbuds, after the primary and secondary earplugs are confirmed or when there is a voice service, Bluetooth is first used to establish a one-way voice link from the primary earplug to the secondary earplug (for example, the one-way voice link can be Bluetooth SCO/eSCO voice link, and the voice link is configured as a one-way link), and then, after receiving the user's first operation, use Bluetooth to establish a one-way voice link from the secondary earbuds to the main earbuds (for example, the one-way voice link The voice link may be a link established by using a Bluetooth serial port profile (Serial Port Profile, SPP), so that a two-way voice link between the left and right earbuds is established. Or, between the left and right earbuds, after the primary and secondary earplugs are confirmed or when there is a voice service, Bluetooth is first used to establish a one-way voice link from the primary earplug to the secondary earplug (for example, the one-way voice link can be Bluetooth SCO/eSCO voice link, and the voice link is configured as a one-way link), and then, after receiving the user's first operation, first remove the previously established one-way voice link, and then use Bluetooth to establish the primary earbud to secondary earbud Earbuds, and a two-way voice link from the secondary earbud to the primary earbud (eg, the two-way voice link is a Bluetooth SCO/eSCO voice link, and the voice link is configured as a two-way link). It should be noted that, in the embodiment of the present application, for the establishment process of the SCO/eSCO voice link, reference may be made to the description of the corresponding content in the Bluetooth standard protocol, which will not be described in detail here. For the above-mentioned voice link 2, whether the TWS headset only turns on the microphone of one of the earbuds, or the microphones of both earbuds are turned on, during the call, there is a demand for the main earbud to send voice data to the mobile phone 1, and the mobile phone 1 to the main phone. Earbuds are required to send voice data, so the voice link 2 above is a two-way voice link. That is, the mobile phone 1 can send voice data to the main earbud through the voice link 2, and the main earbud can also send voice data to the mobile phone 1 through the voice link 2.

In the embodiment of the present application, there may be multiple implementation manners for the foregoing first operation.

Method 1: The earbuds or earphone box of the TWS headset are equipped with function keys, which are called meeting mode function keys or other names, which are not limited in the embodiment of the present invention. The function key is a newly added button on the earplug or the earphone box, or reuses an existing button on the earplug or the earphone box. The first operation is to trigger the function key, for example, press, or toggle, or touch, or tap the function key to trigger the function key. The following uses the meeting mode function key as an example to illustrate. In this mode, after the function key is triggered, the specific implementation of the auxiliary earbuds turning on the microphone of the auxiliary earbuds can be: Function keys, the earphone box saves the primary and secondary role information of the left and right earbuds as an example. When the meeting mode function key is triggered, the headphone box of the TWS earphone can send an instruction to the main earbud, and the instruction is used to instruct the secondary earphone to turn on the microphone of the secondary earphone. The main earplug can send the indication to the secondary earplug through the above-mentioned control link 1 . Alternatively, the earphone box may also send the indication to the pair of earbuds. The pair of earbuds can turn on the microphone of the pair of earbuds according to the received instruction. It should be noted that the earphone box can send the above indication to the main earbuds or the secondary earbuds through a wireless connection (such as a Bluetooth connection) with the main earbuds or the secondary earbuds. When the auxiliary earplugs are not taken out of the earphone box, the earphone box may also send the above indication to the auxiliary earplugs through a wired connection with the auxiliary earplugs. As another example, take the conference mode function keys configured on the earplugs of the TWS headset as an example. When the conference mode function key of the secondary earbuds (wherein the conference mode function key of the secondary earplugs may be the first function key in this application) is triggered, the secondary earplugs can turn on the microphone of the secondary earplugs. Or, when the meeting mode function key of the main earbud (the meeting mode function key of the main earbud can be the second function key in this application) is triggered, the main earbud can send an instruction to the auxiliary earbud through the above-mentioned control link 1 . The pair of earbuds can turn on the microphone of the pair of earbuds according to the received instruction.

Method 2: The mobile phone 1 is equipped with a hardware function key, which is called a conference mode function key or other names, which is not limited in the embodiment of the present invention. The hardware function key may be the third function key in this application. The function key is a newly added key on the mobile phone 1, or reuses an existing key on the mobile phone 1 (such as a volume key, or a power key, etc.). The first operation is to trigger the function key, for example, press, or toggle, or touch, or tap the function key to trigger the function key. The function key of the conference mode is used as an example for illustration below. In this mode, after the function key is triggered, the specific implementation of the secondary earbuds to turn on the microphone of the secondary earplug can be: for example, when the function key of the conference mode is triggered, the mobile phone 1 An instruction can be sent to the main earbud of the TWS headset through the above-mentioned control link 2, and the instruction is used to instruct the secondary earphone to turn on the microphone of the secondary earphone. The main earplug can send the indication to the secondary earplug through the above-mentioned control link 1 . The pair of earbuds can turn on the microphone of the pair of earbuds according to the received instruction.

Mode 3: The mobile phone 1 can display a functional control on the interface. The functional control is called a conference mode control, or a multi-person mode control, or other names, which are not limited in this embodiment of the present invention. The first operation is to trigger the function control, for example, single click, or double click, or heavy pressure, etc. The following takes the conference mode control as an example for illustration. Exemplarily, the conference mode control may be included in the notification bar of the mobile phone 1 . The conference mode control can also be included in the call interface, call interface, answer interface or setting interface displayed on the mobile phone 1 . For example, mobile phone 1 is the calling device, and mobile phone 2 is the called device. The mobile phone 1 can receive the operation of making a call. As shown in FIG. 7 , in response to the operation of making a call, the mobile phone 1 may display a call interface 701 , and the call interface 701 includes a conference mode control 702 . When the mobile phone 1 receives a trigger of the conference mode control 702 from the user, in response to the trigger, the mobile phone 1 can turn on the microphone of the pair of earbuds. In response to the operation of making a call, mobile phone 1 may also send a call request message to mobile phone 2 . When the user of the mobile phone 2 chooses to answer the incoming call, the mobile phone 1 and the mobile phone 2 can communicate. For another example, as shown in FIG. 8 , during a call, the mobile phone 1 may display a call interface 801 , and the call interface 801 includes a conference mode control 802 . When the mobile phone 1 receives the trigger of the conference mode control 802 from the user, in response to the trigger, the mobile phone 1 can turn on the microphone of the pair of earbuds. For another example, mobile phone 1 is the called device, and mobile phone 2 is the calling device. When the mobile phone 1 receives the call request message from the mobile phone 2 , as shown in FIG. 9 , the mobile phone 1 may display an answering interface 901 , and the answering interface 901 includes a conference mode control 902 . When the mobile phone 1 receives the trigger of the conference mode control 902 from the user, in response to the trigger, the mobile phone 1 can turn on the microphone of the pair of earbuds. The answering interface 901 may also include an answering button 903 . The mobile phone 1 can also receive the user's click operation on the answer button 903 , and in response to the click operation, the mobile phone 1 can communicate with the mobile phone 2 . In this way, the specific implementation of the mobile phone 1 turning on the microphone of the secondary earplugs can be: for example, when the conference mode control (such as the above-mentioned conference mode control 702, conference mode control 802, and conference mode control 902) is triggered, the mobile phone 1 can pass The above-mentioned control link 2 sends an instruction to the main earphone of the TWS earphone, and the instruction is used to instruct the secondary earphone to turn on the microphone of the secondary earphone. The main earplug can send the indication to the secondary earplug through the above-mentioned control link 1 . The pair of earbuds can turn on the microphone of the pair of earbuds according to the received instruction.

When the microphones of the left and right earbuds of the TWS headset are turned on, user 1 uses one earbud of the TWS headset (such as the right earbud), user 3 uses the other earplug of the TWS headset (such as the left earbud) and the user of the mobile phone 2 2. The three can talk, and a three-person conference call can be realized. Among them, in combination with Figure 6, continue to take the right earplug as the main earplug of the TWS headset, and the left earplug as the secondary earplug of the TWS headset as an example.

In some embodiments, the mobile phone 2 may collect the voice signal of the user 2 during the speaking process of the user 2 . The mobile phone 2 converts the collected sound signal into voice data, such as voice data 2, which can be sent to the mobile phone 1. Wherein, the voice data 2 may be the second voice data in this application.

After the mobile phone 1 receives the voice data 2 from the mobile phone 2, it can send the voice data 2 to the right earbud as the main earbud of the TWS earphone through the above-mentioned voice link 2.

The left earbud as a pair of earbuds can collect sound signals through the microphone of the left earbud and convert them into voice data, such as voice data 3 . The left earbud can send the voice data 3 to the right earbud through the above-mentioned voice link 1 . It should be noted that, if the user 3 speaks, the voice data 3 may be the voice data obtained by processing the sound signal emitted by the user 3 . If the user 3 does not speak, the voice data 3 may be silent data. Wherein, the voice data 3 may be the third voice data in this application.

The right earplug can perform superposition processing (or called sound mixing processing) on the above-mentioned voice data 2 and voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 2-3. The right earplug can play the voice data 2-3 through the receiver (ie earpiece) of the right earplug.

The right earbud can also collect sound signals through the microphone of the right earbud and convert them into voice data, such as voice data 1 . If the user 1 speaks, the voice data 1 may be the voice data obtained by processing the sound signal emitted by the user 1 . If the user 1 does not speak, the voice data 1 may be silent data. Wherein, the voice data 1 may be the first voice data in this application.

The right earbud can perform superposition processing on the voice data 1 and the received voice data 2 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 1-2. The right earplug can send the voice data 1-2 to the left earplug through the above-mentioned voice link 1. After the left earplug receives the voice data 1-2, the voice data 1-2 can be played through the receiver of the left earplug.

In addition, the right earplug can also perform superposition processing on the above-mentioned voice data 1 and the above-mentioned voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 1-3. The right earbud can send the voice data 1-3 to the mobile phone 1 through the above-mentioned voice link 2. After receiving the voice data 1-3, the mobile phone 1 can send the voice data 1-3 to the mobile phone 2, so that the mobile phone 2 can play the voice data 1-3.

It can be seen that the above-mentioned right earplug, which is the main earplug of the TWS headset, needs to superimpose (or mix) the multi-channel voice data. For example, the right earbud needs to superimpose the voice data 2 from the mobile phone 1 and the voice data 3 from the left earbud, the voice data 1 collected by the right earbud and the voice data 2 from the mobile phone 1 need to be superimposed, and the right earbud collects The received voice data 1 and the voice data 3 from the left earbud are superimposed. In the embodiment of the present application, a sound mixer may be added to the right earbud serving as the main earbud of the TWS earphone to perform superimposition processing on multiple channels of voice data. Of course, since any of the left and right earbuds of the TWS headset may be used as the main earplug, a mixer can be added to both the left and right earplugs of the TWS headset. Alternatively, the processor included in the earplug of the TWS earphone can also use a software algorithm to realize the superposition processing of multiple channels of voice data.

In some other embodiments, if user 1 and user 3 are relatively close and can hear each other's voice, then the right earplug as the main earplug may not perform the above-mentioned superposition processing of voice data 2 and voice data 3 , but play the voice data 2 from the mobile phone 1 through the receiver of the right earbud. The right earplug may not perform the above-mentioned superposition processing of the voice data 1 and the voice data 2, but just send the voice data 2 to the left earplug for playback.

In this way, by turning on the microphones of the left and right earbuds of the TWS headset connected to a mobile phone and sharing them with two users, it is more convenient to realize more than two people's calls, that is, to realize multi-person conference calls. In addition, the possibility of environmental noise interfering with the call effect can be reduced.

As shown in Figure 10, in this embodiment, the connection mode of the Bluetooth connection between the TWS headset and the mobile phone 1 is used as the monitoring mode, the user of the mobile phone 1 is called user 1, and the user of the mobile phone 2 is called user 2 as an example. introduce.

The left earbud and the right earbud of the TWS headset establish control link 1. Among the left and right earplugs of the TWS earphone, the earplug (such as the right earplug) serving as the main earplug establishes a control link 2 with the mobile phone 1 . Wherein, the control link 1 may be the first control link in this application. The control link 2 may be the second control link in this application. The primary earplug may be the first earplug in this application, and the secondary earplug may be the second earplug in this application.

Among them, in this embodiment, for the specific description of establishing the control link 1 between the left and right earplugs, and the establishment of the control link 2 between the earplug as the main earplug and the mobile phone 1, you can refer to the implementation shown in Figure 6 respectively. The specific description of the corresponding content in the example will not be described in detail here.

For voice links used to transmit voice data during a call, see, for example, voice link 1 and voice link 2 shown in FIG. 10 . For a specific description of the voice link 2, reference may be made to the specific description of the corresponding content in the embodiment shown in FIG. 6 . Voice link 1 may be the first voice link in this application. Voice link 2 may be the second voice link in this application. The specific description of voice link 1 is similar to the specific description of the corresponding content in the embodiment shown in Figure 6, the difference is that:

The first difference is that in the forwarding mode, the secondary earbuds obtain the voice data from the mobile phone 1 through the forwarding of the main earbuds. In the monitoring mode, the secondary earbuds obtain voice data from the mobile phone 1 by monitoring the voice link (such as voice link 2) between the main earbuds and the mobile phone 1 . Therefore, different from the voice link 1 in the embodiment shown in FIG. 6, in this embodiment, the above-mentioned voice link 1 is used to transmit the voice data obtained by processing the sound signal collected by the right earplug, and the voice data collected by the left earplug. Speech data obtained by sound signal processing. Among them, the voice link 1 will only have voice data transmission when the microphones of the left and right earbuds of the TWS headset are turned on.

Difference 2. In this embodiment, the voice link 1 can be established not only after the primary and secondary earbuds are confirmed, but also when there is a voice service, and can also be established after the Bluetooth pairing of the left and right earbuds is completed. It can also be established after receiving the above-mentioned first Build after operation.

Difference 3. Since the voice link 1 is used to transmit the voice data obtained by processing the sound signal collected by the right earplug, and the voice data obtained by processing the sound signal collected by the left earplug, therefore, in this embodiment, the Once voice link 1 is to be established, a two-way voice link needs to be established.

In addition, in this embodiment, after the right earbud as the main earbud establishes the voice link 2 with the mobile phone 1, the right earbud can also send the connection of the voice link 2 to the left earbud as the secondary earbud through the above-mentioned control link 1. parameter. For example, the connection parameters may include the Bluetooth address of the mobile phone 1, codec parameters, clock parameters, and encryption parameters negotiated between the mobile phone 1 and the main earbud. According to the link parameters, the left earbud can monitor the voice link 2 between the main earbud and the mobile phone 1 to obtain the voice data sent by the mobile phone 1 .

In some embodiments, the earplug serving as the main earplug among the left and right earplugs of the TWS earphone can also turn on the microphone of the earplug for collecting the sound signal of the user (such as user 1). When wanting to implement a multi-person conference call, for example, when user 3 wants to access a call through mobile phone 1, one of the left and right earplugs of the TWS headset can be shared with user 3 for use. That is to say, user 1 and user 3 can respectively use the left and right earbuds in the TWS headset to make a call. In the process of multiple people conducting a conference call, there is not only a demand for collecting the voice signal of user 1, but also a demand for collecting the voice signal of user 3. Therefore, it is not only necessary to turn on the microphone of the earplug as the main earplug in the TWS earphone, but also the microphone of the earplug as the secondary earplug. In the embodiment of the present application, the user can perform the first operation to turn on the microphones of the earplugs serving as the pair of earplugs, so that the microphones of the left and right earplugs of the TWS earphone are all turned on.

In this embodiment, for the microphones of the left and right earbuds of the TWS earphones are turned on, and the specific description of the implementation of the first operation, you can refer to the specific description of the corresponding content in the embodiment shown in FIG. 6 , this embodiment No more details are given here.

When the microphones of the left and right earbuds of the TWS headset are turned on, user 1 uses one earbud of the TWS headset (such as the right earbud), user 3 uses the other earplug of the TWS headset (such as the left earbud) and the user of the mobile phone 2 2. The three can talk, and a three-person conference call can be realized. Wherein, referring to FIG. 10 , continue to take the right earplug as the main earplug of the TWS headset, and the left earplug as the secondary earplug of the TWS headset as an example.

In some embodiments, the mobile phone 2 may collect the voice signal of the user 2 during the speaking process of the user 2 . The mobile phone 2 converts the collected sound signal into voice data, such as voice data 2, which can be sent to the mobile phone 1.

After the mobile phone 1 receives the voice data 2 from the mobile phone 2, it can send the voice data 2 to the right earbud as the main earbud of the TWS earphone through the above-mentioned voice link 2. Wherein, the voice data 2 may be the second voice data in this application.

The left earbud as a pair of earbuds can collect sound signals through the microphone of the left earbud and convert them into voice data, such as voice data 3 . The left earbud can send the voice data 3 to the right earbud through the above-mentioned voice link 1 . It should be noted that, if the user 3 speaks, the voice data 3 may be the voice data obtained by processing the sound signal emitted by the user 3 . If the user 3 does not speak, the voice data 3 may be silent data. Wherein, the voice data 3 may be the third voice data in this application.

The right earplug can perform superposition processing (or called sound mixing processing) on the above-mentioned voice data 2 and voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 2-3. The right earplug can play the voice data 2-3 through the receiver (ie earpiece) of the right earplug.

The right earbud can also collect sound signals through the microphone of the right earbud and convert them into voice data, such as voice data 1 . If the user 1 speaks, the voice data 1 may be the voice data obtained by processing the sound signal emitted by the user 1 . If the user 1 does not speak, the voice data 1 may be silent data. The right earplug can send the voice data 1 to the left earplug through the voice link 1 mentioned above. Wherein, the voice data 1 may be the first voice data in this application.

The left earbud can also monitor the voice link 2 between the mobile phone 1 and the right earbud to obtain voice data 2 .

The left earbud can superimpose voice data 1 and voice data 2 to achieve a sound mixing effect. For example, the voice data after superposition is called voice data 1-2. The left earplug can play the voice data 1-2 through the receiver of the left earplug.

In addition, the right earplug can also perform superposition processing on the above-mentioned voice data 1 and the above-mentioned voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 1-3. The right earbud can send the voice data 1-3 to the mobile phone 1 through the above-mentioned voice link 2. After receiving the voice data 1-3, the mobile phone 1 can send the voice data 1-3 to the mobile phone 2, so that the mobile phone 2 can play the voice data 1-3.

It can be seen that the above-mentioned right earplug as the main earplug of the TWS earphone and the left earplug as the secondary earplug need to superimpose (or mix) the multi-channel voice data. For example, the right earbud needs to superimpose the voice data 2 from the mobile phone 1 and the voice data 3 from the left earbud, and superimpose the voice data 1 collected by the right earbud and the voice data 3 from the left earbud. The left earbud needs to superimpose the voice data 1 from the right earbud and the monitored voice data 2 . In the embodiment of the present application, mixers can be added to the left and right earbuds of the TWS headset, or the processor included in the earplugs of the TWS headset can use software algorithms to realize the superposition processing of multiple voice data.

In some other embodiments, if user 1 and user 3 are relatively close and can hear each other's voice, then the right earplug as the main earplug may not perform the above-mentioned superposition processing of voice data 2 and voice data 3 , but play the voice data 2 from the mobile phone 1 through the receiver of the right earbud. The right earbud may not transmit the above-mentioned voice data 1 to the left earbud, and the left earbud may not perform the superposition processing of the above-mentioned voice data 1 and voice data 2, but just play the voice data 2 obtained by listening to the voice link 2. The above-mentioned voice link 1 may not be a two-way voice link, but a one-way voice link from the left earplug as the secondary earplug to the right earplug as the main earplug, for transmitting voice data 3 from the left earplug to the right earplug, so that The right earbud mixes the voice data 3 and the collected voice data 1 and sends them to the mobile phone 1 .

In this way, by turning on the microphones of the left and right earbuds of the TWS headset connected to a mobile phone and sharing them with two users, it is more convenient to realize more than two people's calls, that is, to realize multi-person conference calls. In addition, the possibility of environmental noise interfering with the call effect can be reduced.

As shown in Figure 11, in this embodiment, the connection mode of the Bluetooth connection between the TWS earphone and the mobile phone 1 is a dual transmission mode, the user of the mobile phone 1 is called user 1, and the user of the mobile phone 2 is called user 2 as an example Make an introduction.

The left earbud and the right earbud of the TWS headset establish control link 1.

Wherein, in this embodiment, for the specific description of establishing the control link 1 between the left and right earbuds, reference may be made to the specific description of the corresponding content in the embodiment shown in FIG. 6 , which will not be repeated here. Wherein, the left earplug can be the first earplug in the present application, and the right earplug can be the second earplug in the present application; or, the left earplug can be the second earplug in the present application, and the right earplug can be the first earplug in the present application. earplugs. The control link 1 may be the first control link in this application.

The left and right earbuds of the TWS earphone establish control links with mobile phone 1 respectively.

For example, as shown in FIG. 11 , the right earbud establishes control link 2 with mobile phone 1 , and the left earbud establishes control link 3 with mobile phone 1 . The control link 2 may be the second control link in this application. The control link 3 may be the third control link in this application. In some embodiments, the specific process of establishing a control link between the left earplug and the right earplug of the TWS earphone and the mobile phone 1 may be: any one of the left and right earplugs (such as the right earplug) of the TWS earphone can send a pairing broadcast to the outside. If the mobile phone 1 has turned on the Bluetooth function, the mobile phone 1 can receive the pairing broadcast and prompt the user that a related Bluetooth device (such as a TWS earphone) has been scanned. When the TWS headset is selected as the connection device on the mobile phone 1, the mobile phone 1 can perform Bluetooth pairing with the right earbud of the TWS headset. After the Bluetooth pairing between the right earbud and the mobile phone 1 is completed, the right earbud can establish a control link 2 with the mobile phone 1 using Bluetooth. Of course, if the Bluetooth pairing between the mobile phone 1 and the right earbud of the TWS headset has been completed before, the Bluetooth pairing process can be omitted. That is to say, after receiving the pairing broadcast, the mobile phone 1 can automatically establish a control link 2 with the right earbud using Bluetooth. The right earbud can send the Bluetooth address of mobile phone 1 to the left earbud, so that the left earbud can establish a control link with mobile phone 1. For example, the right earbud can send the Bluetooth address of the mobile phone 1 to the left earbud through the above-mentioned control link 1, and notify the left earbud to send a pairing broadcast. In this way, the mobile phone 1 can receive the pairing broadcast sent by the left earbud and perform Bluetooth pairing with the left earbud. After the Bluetooth pairing between the left earbud and the mobile phone 1 is completed, the left earbud can establish a control link 3 with the mobile phone 1 using Bluetooth. Of course, if the Bluetooth pairing between the mobile phone 1 and the left earbud of the TWS headset has been completed before, the Bluetooth pairing process can be omitted. That is to say, after receiving the pairing broadcast, the mobile phone 1 can automatically establish a control link 3 with the left earbud using Bluetooth.

It should be noted that the above process of establishing a control link between the left earbud and the right earbud of the TWS earphone and the mobile phone 1 is only an example. In some embodiments, the mobile phone 1 can also perform Bluetooth pairing with the left earbud of the TWS earphone and establish a control link, and then the left earbud sends the Bluetooth address of the mobile phone to the right earbud, and notifies the right earbud to send a pairing broadcast, so that The right earbud performs Bluetooth pairing with mobile phone 1 and establishes a control link. In some other embodiments, the left earbud and the right earbud of the TWS earphone can respectively send pairing broadcasts after being turned on, so that the left earbud and the right earbud can perform Bluetooth pairing with the mobile phone 1 respectively, and each establish a control link with the mobile phone 1 . In addition, in this embodiment of the application, the trigger condition for the left or right earplug of the TWS headset to send a pairing broadcast to the outside world may be that the cover of the earphone box of the TWS headset is opened, or the Bluetooth pairing of the left and right earplugs of the TWS headset is completed, or is the pairing function key is pressed. Wherein, the pairing function key can be set on the earphone box of the TWS earphone. For example, the earphone box of the TWS headset is equipped with a pairing function key. When the pairing function key is pressed, the left or right earbud of the TWS headset can send a pairing broadcast to the outside world. The pairing function key can also be set on the left and right earbuds of the TWS headset. For example, the left earbud and/or the right earbud of the TWS headset is equipped with a pairing function key, and when the pairing function key is pressed, the corresponding earbud sends a pairing broadcast to the outside.

In some embodiments, since the TWS earphone is used as a pair of binaural earphones to implement a call, the left and right earplugs of the TWS earphone are usually used by one user (such as user 1), that is, only the sound signal of one user needs to be collected. Therefore, any one of the left and right earplugs of the TWS earphone can also turn on the microphone of the earplug for collecting the sound signal of the user (such as user 1). For example, in some embodiments, the earplug that is taken out of the earphone box first among the left and right earplugs may turn on the microphone of the earplug, and the microphone of the other earplug may not be turned on. Or, among the left and right earbuds, the earplug that first performs Bluetooth pairing with the mobile phone turns on the microphone of the earbud, and the microphone of the other earbud may not be turned on. Alternatively, the left and right earplugs include a pairing function key, the earplug whose pairing function key is pressed first can turn on the microphone of the earplug, and the microphone of the other earplug can not be turned on. Alternatively, the earplug that is worn on the ear first among the left and right earplugs may turn on the microphone of the earplug, and the microphone of the other earplug may not be turned on.

Take determining which earbud turns on the microphone and which one does not turn on the microphone according to the sequence of Bluetooth pairing with the mobile phone as an example. Exemplarily, if the right earbud is first paired with the mobile phone 1 via Bluetooth, the right earbud can turn on the microphone of the right earbud, and the left earbud can not turn on the microphone of the left earbud. In some embodiments, the right earbud can notify the left earbud through the above-mentioned control link 1 that the right earbud has turned on the microphone. In this way, even if the left earbud is worn on the ear, the left earbud will not turn on the microphone of the left earbud.

When wanting to implement a multi-person conference call, for example, when user 3 wants to access a call through mobile phone 1, one of the left and right earplugs of the TWS headset can be shared with user 3 for use. That is to say, user 1 and user 3 can respectively use the left and right earbuds in the TWS headset to make a call. In the process of multiple people conducting a conference call, there is not only a demand for collecting the voice signal of user 1, but also a demand for collecting the voice signal of user 3. Therefore, not only the microphone of one earbud (such as the right earbud) of the TWS headset needs to be turned on, but also the microphone of the other earbud (such as the left earbud) needs to be turned on. In the embodiment of the present application, the user can perform the first operation to turn on the microphone of the other earbud, so that the microphones of the left and right earbuds of the TWS earphone are both turned on.

For example, in some embodiments, it may be defined that the earplug with the microphone turned on is the primary earplug, and the earplug with the microphone not turned on is the secondary earplug. Correspondingly, for the microphones of the left and right earbuds of the TWS earphones are turned on, and the specific description of the implementation of the first operation, you can refer to the specific description of the corresponding content in the embodiment shown in FIG. Let me go into more detail. In other embodiments, the mobile phone 1 may also record which earplug's microphone is turned on and which earplug's microphone is not turned on among the left and right earbuds of the TWS earphone. After the user performs the first operation, the mobile phone 1 may send an instruction to the earplug through the control link with the earplug whose microphone is not turned on, so as to instruct the earplug to turn on the microphone.

For voice links used to transmit voice data during a call, see, for example, voice link 1, voice link 2, and voice link 3 shown in FIG. 11 . Voice link 1 may be the first voice link in this application. Voice link 2 may be the second voice link in this application. Voice link 3 may be the third voice link in this application. For a specific description of the voice link 2, reference may be made to the specific description of the corresponding content in the embodiment shown in FIG. 6 . The specific description of voice link 1 is similar to the specific description of the corresponding content in the embodiment shown in Figure 6, the difference is that:

The first difference is that in the forwarding mode, the secondary earbuds obtain the voice data from the mobile phone 1 through the forwarding of the main earbuds. In the dual-send mode, the mobile phone 1 can send voice data to the left earplug and the right earplug respectively. Therefore, different from the voice link 1 in the embodiment shown in FIG. 6, in this embodiment, the above-mentioned voice link 1 is used to transmit the voice data obtained by processing the sound signal collected by the right earplug, and the voice data collected by the left earplug. Speech data obtained by sound signal processing. Among them, the voice link 1 will only have voice data transmission when the microphones of the left and right earbuds of the TWS headset are turned on.

Difference 2. In this embodiment, the voice link 1 can be established when there is a voice service, can be established after the Bluetooth pairing of the left and right earbuds is completed, and can also be established after receiving the above-mentioned first operation.

Difference 3. Since the voice link 1 is used to transmit the voice data obtained by processing the sound signal collected by the right earplug, and the voice data obtained by processing the sound signal collected by the left earplug, therefore, in this embodiment, the Once voice link 1 is to be established, a two-way voice link needs to be established.

Difference 4. The voice link 1 can be not only a Bluetooth SCO/eSCO voice link, but also a connected isochronous stream (CIS) chain based on an isochronous (ISO) channel (channel) road. In the embodiment of the present application, for the establishment process of the CIS link based on the ISO channel, reference may be made to the description of the corresponding content in the standard protocol of the ISO channel, and details will not be repeated here.

In addition, in this embodiment, not only the right earbud of the TWS earphone needs to establish a voice link with the mobile phone 1, such as the above-mentioned voice link 2, but also the left earbud needs to establish a voice link with the mobile phone 1, such as the voice link 3. The left earplug can obtain the voice data sent by the mobile phone 1 through the voice link 3 , and can also send the voice data to the mobile phone 1 .

In conjunction with Figure 11, when the microphones of the left and right earplugs of the TWS headset are turned on, user 1 uses one earplug of the TWS headset (such as the right earplug), user 3 uses the other earplug of the TWS headset (such as the left earplug) and uses The user 2 of the mobile phone 2, the three can talk, and the three-person conference call can be realized.

In some embodiments, the mobile phone 2 may collect the voice signal of the user 2 during the speaking process of the user 2 . The mobile phone 2 converts the collected sound signal into voice data, such as voice data 2, which can be sent to the mobile phone 1.

After the mobile phone 1 receives the voice data 2 from the mobile phone 2, it can send the voice data 2 to the right earbud of the TWS headset through the above-mentioned voice link 2. The mobile phone 1 can also send the voice data 2 to the left earbud of the TWS headset through the above-mentioned voice link 3 . Wherein, the voice data 2 may be the second voice data in this application.

The left earbud can collect sound signals through the microphone of the left earbud and convert them into voice data, such as voice data 3 . The left earbud can send the voice data 3 to the right earbud through the above-mentioned voice link 1 . The left earplug can also send the voice data 3 to the mobile phone 1 through the above-mentioned voice link 3 . It should be noted that, if the user 3 speaks, the voice data 3 may be the voice data obtained by processing the sound signal emitted by the user 3 . If the user 3 does not speak, the voice data 3 may be silent data. Wherein, the voice data 3 may be the third voice data in this application.

The right earplug can perform superposition processing (or called sound mixing processing) on the above-mentioned voice data 2 and voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 2-3. The right earplug can play the voice data 2-3 through the receiver (ie earpiece) of the right earplug.

The right earbud can also collect sound signals through the microphone of the right earbud and convert them into voice data, such as voice data 1 . If the user 1 speaks, the voice data 1 may be the voice data obtained by processing the sound signal emitted by the user 1 . If the user 1 does not speak, the voice data 1 may be silent data. The right earplug can send the voice data 1 to the left earplug through the voice link 1 mentioned above. The right earplug can also send the voice data 1 to the mobile phone 1 through the above-mentioned voice link 2 . Wherein, the voice data 1 may be the first voice data in this application.

The left earbud can superimpose voice data 1 and voice data 2 to achieve a sound mixing effect. For example, the voice data after superposition is called voice data 1-2. The left earplug can play the voice data 1-2 through the receiver of the left earplug.

In addition, the mobile phone 1 may also perform superposition processing on the above-mentioned voice data 1 and the above-mentioned voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is called voice data 1-3. The mobile phone 1 can send the voice data 1-3 to the mobile phone 2, so that the mobile phone 2 can play the voice data 1-3.

It can be seen that the above-mentioned right earplug, left earplug and mobile phone 1 need to perform superposition (or sound mixing) processing on the multi-channel voice data. For example, the right earbud needs to superimpose the voice data 2 from the mobile phone 1 and the voice data 3 from the left earbud. The left earbud needs to superimpose the voice data 1 from the right earbud and the voice data 2 from the mobile phone 1 . The mobile phone 1 needs to perform superposition processing on the voice data 1 from the right earbud and the voice data 3 from the left earbud. In the embodiment of the present application, mixers can be added to the left and right earbuds of the TWS headset, or the processor included in the earplugs of the TWS headset can use software algorithms to realize the superposition processing of multiple voice data. A sound mixer can be added to the mobile phone 1, or the processor of the mobile phone 1 can use a software algorithm to realize the superposition processing of multiple channels of voice data.

In some other embodiments, if user 1 and user 3 are relatively close and can hear each other's voice, then the left and right earplugs may not perform the above-mentioned superposition processing of the voice data, but play the data from the mobile phone 1 through the receiver. The voice data of 2 is enough. In this way, there is no need to establish a voice link between the left and right earbuds, that is, there is no need to establish the above voice link 1 .

In this way, by turning on the microphones of the left and right earbuds of the TWS headset connected to a mobile phone and sharing them with two users, it is more convenient to realize more than two people's calls, that is, to realize multi-person conference calls. In addition, the possibility of environmental noise interfering with the call effect can be reduced.

In addition, in the embodiments shown in FIG. 6 , FIG. 10 and FIG. 11 , the mobile phone 2 can also be connected to a TWS headset for use by two users, so that a four-person conference call can be realized. It should be noted that, the connection mode of the Bluetooth connection between the mobile phone 2 and the TWS headset can be any one of the above-mentioned forwarding mode, monitoring mode and dual transmission mode. The connection method of the Bluetooth connection between the mobile phone 1 and the TWS headset may be the same as or different from the connection method of the Bluetooth connection between the mobile phone 2 and the TWS headset. For the specific implementation of the TWS headset as the audio input/output device of the mobile phone 2 to realize the call, you can refer to the specific description of the corresponding content in the call that the TWS headset is used as the audio input/output device of the mobile phone 1 in the above embodiment, and will not be repeated here. repeat.
