In the forwarding scheme, the TWS earphone can comprise a main earplug and an auxiliary earplug, bluetooth connection is established between the mobile phone and the main earplug, the transmission of audio data to the main earplug is completed, and service actions triggered by the mobile phone and the TWS earphone are completed; bluetooth connection is established between the two earplugs, information synchronization between the two earplugs is completed, and the main earplugs forward audio data to the auxiliary earplugs through Bluetooth links between the main earplugs and the auxiliary earplugs.

In the NFMI scheme, the TWS earphone may include a main earplug and an auxiliary earplug, and bluetooth connection is established between the mobile phone and the main earplug, so as to complete transmission of audio data to the main earplug and complete service actions triggered by the mobile phone and the TWS earphone; and NFMI connection is established between the two earplugs, information synchronization between the two earplugs is completed, and the main earplug forwards audio data to the auxiliary earplugs through NFMI links between the main earplugs and the auxiliary earplugs.

In the monitoring scheme, the forwarding scheme and the NFMI scheme, the mobile phone only establishes Bluetooth connection with the main earplug, and exchanges audio data with the main earplug; the mobile phone does not establish a bluetooth connection with the auxiliary earplug and does not interact audio data with the auxiliary earplug, so the connection schemes can also be called as a single-shot scheme.

Referring to fig. 4, in the dual-transmission scheme, the mobile phone establishes bluetooth connection with two earplugs of the TWS, respectively, so as to implement operations such as audio data playing and service action control by interacting with audio data, service control data, etc. through bluetooth links between the two earplugs of the TWS, respectively. The two earplugs of the TWS can be connected in a wireless mode or disconnected in a wireless mode. Specific details regarding the two-shot approach may be found among others in application documents having application numbers PCT/CN2018/118783, PCT/CN2018/118730, and PCT/CN 2018/118791.

The following embodiments of the present application mainly take a two-way connection between a mobile phone and a TWS headset as an example.

The TWS headset may interact with audio (audio) data, which may include media (media) data, voice (voice) data, etc., through a Bluetooth bi-directional connection with the handset. For example, TWS headphones may play media data such as music, recordings, sounds in video files, etc. for a user; in the scenes of telephone, audio call and video call, the method can play incoming call prompt tone, play voice data of the opposite end of the call, collect voice data of a user and send the voice data to a mobile phone; in a game scene, background music, game prompt tone, voice data of game teammates and the like can be played, and voice data of users are collected and sent to a mobile phone; under the WeChat voice message scene, voice message can be played, voice data recorded by a user are collected and sent to a mobile phone; under the scenes of voice assistants and the like, voice data of a user can be collected and sent to the mobile phone.

Specifically, the left earplug and the right earplug of the TWS earphone are provided with MICs, and the MICs can be used for collecting voice data of a user in voice service and sending the voice data to a mobile phone for voice service processing. For example, in voice services such as telephone service, weChat audio/video chat service, weChat voice message service, etc., MIC on the ear plug can be used for collecting voice data of the user, and the voice data is sent to the opposite terminal after being processed by the mobile phone; the system can also be used for collecting voice instructions of users for indicating to dial/connect a phone, connect an audio/video call and the like and sending the voice instructions to a mobile phone. For another example, in a voice control service (e.g., a voice assistant service), the MIC on the earplug may be used to collect voice instructions from the user and send to the handset, e.g., to instruct to turn on an APP, to instruct to start playing music, to instruct to play the next piece of music, to instruct to pause playing music, etc. For another example, in a gaming service, the MIC on the ear plug may be used to collect voice data from a user and send it to a game player via a cell phone. It may be appreciated that the voice service may also include other service scenarios, which are not limited in the embodiments of the present application.

In order to reduce power consumption, resources, duty cycle, etc. of a mobile phone, the mobile phone generally only uses voice data sent by the MIC of one TWS earplug to perform voice service processing.

The following embodiments of the present application mainly take a voice service as a telephone service as an example for explanation. Referring to fig. 5, the method may include:

500. the handset establishes a bluetooth connection with each TWS earpiece while maintaining the two bluetooth connections.

The TWS headset may include a first earpiece and a second earpiece, and the handset may establish a first Bluetooth connection with the first earpiece and a second Bluetooth connection between the handset and the second earpiece while maintaining both Bluetooth connections. Namely, a double-transmission connection is established between the mobile phone and the TWS earphone. After the dual-send connection is established, the mobile phone can send audio data to the first earplug through the first Bluetooth connection, send audio data to the second earplug through the second Bluetooth connection, and enable the first earplug and the second earplug to synchronously play the audio data.

501. The handset initiates a telephone service.

When a user wishes to make a call, the handset may first establish a two-way connection with the TWS headset, and then the handset may initiate a phone service (e.g., make or receive a call) to make a call using the TWS headset.

Illustratively, in the telephone service scenario shown in fig. 6 (a), as shown in fig. 6 (b), the user may make a call using the TWS headset.

In a telephone service scene, the first earplug can receive voice data of a telephone opposite terminal sent by a mobile phone through a first Bluetooth connection, the second earplug can receive voice data of the telephone opposite terminal sent by the mobile phone through a second Bluetooth connection, and a user can answer the voice data of the telephone opposite terminal through the first earplug and the second earplug. And the MIC of the TWS earphone can also collect voice data of a local user and send the voice data to the mobile phone, and the mobile phone processes the voice data of the user and sends the voice data to the opposite terminal.

Or, the mobile phone can also start the telephone service first and make a call by adopting other modes such as a receiver and the like; after the mobile phone establishes the double-sending connection with the TWS earphone, the mobile phone is switched to be connected with the telephone through the TWS earphone. Illustratively, in the telephone service scenario shown in fig. 6 (c), the user uses the handset to answer the call; the user may also click on control 601 to switch answer modes; after the user clicks the control 602 shown in (d) in fig. 6 to select the TWS earphone mode to answer, the mobile phone may establish a two-way connection with the TWS earphone, and then referring to (b) in fig. 6, the user may use the TWS earphone to answer a call.

502. The mobile phone receives voice data collected by the MIC of the first earplug.

After the mobile phone establishes the double-sending connection with the TWS earphone and starts the telephone service, the mobile phone can determine a target earplug (a left earplug or a right earplug) according to a preset strategy, and then receives voice data which are sent by the target earplug and collected by the MIC of the target earplug through Bluetooth connection with the target earplug.

The preset strategy can be various. For example, by default the right earplug of the TWS headset is the target earplug, the earplug may report an identification to the phone to indicate whether it is the left earplug or the right earplug, and the phone determines the earplug identified as the right earplug as the target earplug according to the identification.

For another example, the earplug that is first removed from the earphone box is the target earplug. The mobile phone can be notified when the earplug is out of the box, and the mobile phone determines that the earplug which firstly receives the out-box notification is the target earplug. Wherein the TWS earphone arranged in the earphone box is kept in contact with or electrically connected with the earphone box; when the earplug is taken out of the earphone box, the earplug is separated from the earphone box.

For another example, a first in ear earplug is the target earplug. The earbud may determine whether to be in the ear by a proximity light sensor, an ambient light sensor, or a distance sensor; if the in-ear is determined, the earplug sends an in-ear notification to the mobile phone to indicate that the earplug is in-ear, and the mobile phone can determine the earplug which sends the in-ear notification first as a target earplug.

For another example, the user may indicate whether the target earplug is a left earplug or a right earplug. For example, two earplugs can be respectively displayed on a display screen of the mobile phone, and a user can select one of the earplugs as a target earplug; for another example, the user may indicate that one of the earpieces is the target earpiece by the MIC of the cell phone or by MIC speech of the earpieces; for another example, if one earplug detects the touch operation of the user on the first control, the operation is reported to the mobile phone, and the mobile phone determines that the earplug is the target earplug.

For another example, of the two earplugs in the TWS headset, the earplug that first established the connection with the handset may be the target earplug.

For another example, after the dual-transmission connection is established, the mobile phone can obtain the electric quantity of the first earplug through the first Bluetooth connection and obtain the electric quantity of the second earplug through the second Bluetooth connection, so that the earplug with the larger electric quantity in the TWS earphone is determined to be the target earplug.

For another example, after the dual-hop connection is established, an earpiece with high channel quality of the bluetooth link with the handset in the TWS earpiece is the target earpiece.

If the mobile phone determines that the first earplug is the target earplug, the mobile phone can receive voice data acquired by the MIC of the first earplug, which is sent by the first earplug, through a first Bluetooth connection between the mobile phone and the first earplug.

503. And the mobile phone performs telephone service processing according to the voice data acquired by the MIC of the first earplug.

After receiving the voice data collected by the MIC of the first earplug, the mobile phone can perform phone service processing according to the voice data. For example, the voice data is encoded, compressed, and the like, and transmitted to the counterpart device.

After step 503, the method may further include:

504. if the first earplug meets the switching condition, the mobile phone performs telephone service processing according to voice data acquired by the MIC of the second earplug.

When the phone service is processed according to the voice data collected by the MIC of the first earplug, if the first earplug meets the switching condition, it can be indicated that the first earplug has a problem, and the MIC of the first earplug may not normally provide the voice data for the phone service of the phone. The handset may switch to providing voice data for the telephone service via the MIC of the second earpiece so that telephone service processing is performed based on the voice data collected by the MIC of the second earpiece. Here, a specific explanation about the switching condition can be found in the description in the following embodiment.

After the two-way connection between the mobile phone and the TWS headset is established and the telephone service is started, the mobile phone can determine and record whether the MICs of the first earplug and the second earplug are in the on state or the off state. And, the mobile phone may be notified when the open/close states of the MIC of the first and second earplugs are changed, and the mobile phone may record the open/close states of the MIC of the first and second earplugs after the change.

When the MIC of the first earplug provides voice data for voice service of the mobile phone, if the MIC of the first earplug is in an open state and the MIC of the second earplug is in a closed state, executing the MIC switching process described in the following case 1; if the MIC of both the first earpiece and the second earpiece are in an on state, the MIC switching process described in case 2 below is performed.

Case 1: when the mobile phone carries out telephone service processing according to voice data collected by the MIC of the first earplug, the MIC of the second earplug is in a closed state.

After the mobile phone establishes bluetooth connection with the first earplug and the second earplug, the MIC of the first earplug and the MIC of the second earplug can be in an open state by default, the mobile phone can instruct to close the MIC of the second earplug, and keep the MIC of the first earplug in the open state, so that voice data is provided for telephone service by using the MIC of the first earplug. Or, the mobile phone can indicate that one of the earplugs is a first earplug, and the MIC of the first earplug is in an open state; the phone may indicate that the other earpiece is a second earpiece, which automatically closes the MIC.

Or after the mobile phone establishes bluetooth connection with the first earplug and the second earplug, the MIC of the first earplug and the MIC of the second earplug can be in a closed state by default, the mobile phone can instruct to open the MIC of the first earplug, and keep the MIC of the second earplug in the closed state, so that voice data is provided for telephone service by using the MIC of the first earplug. Or, the mobile phone may indicate one of the earplugs as the first earplug, and the first earplug automatically opens the MIC; the handset may indicate that the other earplug is a second earplug, which remains closed.

In an embodiment, the first earplug meeting the switching condition in step 504 includes the first earplug meeting a first preset condition. That is, referring to fig. 5, step 504 may specifically include:

504A, if the first earplug meets the first preset condition, the mobile phone performs phone service processing according to the voice data collected by the MIC of the second earplug.

Wherein the first preset condition may include one or more of: the method comprises the steps of outputting an ear (separating from the ear), wherein the time of outputting the ear is larger than or equal to a first preset value, disconnecting the mobile phone from the chain (namely disconnecting the mobile phone from Bluetooth), the electric quantity is smaller than a second preset value, the channel quality of a link between the mobile phone and the electric quantity is lower than a third preset value, or voice data (of the opposite terminal) are not played in a preset time period, voice data (of the MIC of the earplug) are not collected (of a local user), and the like. Among these, there may be various parameters for representing channel quality, such as one or more of packet loss rate, packet error rate, signal-to-noise ratio, qoS parameters, channel quality indication (channel quality indicator, CQI) parameters, etc.

If the first earplug meets the first preset condition, it may indicate that the first earplug has a problem, and the MIC of the first earplug may not normally provide voice data for phone service of the mobile phone. At this time, whether the second earplug has the same problem as the first earplug or not, the second earplug can be switched to provide voice data to the telephone service of the mobile phone through the MIC of the second earplug so that the mobile phone can process the telephone service normally or better.

For the detection of the coming out of the ear, the earplug can determine whether the earplug is separated from the ear or not through a distance sensor or an approaching light sensor, and if the earplug is separated from the ear, the earplug is reported to the mobile phone. For broken link detection, the earplug may send a reset (reset) or detach (detach) or the like to the handset indicating a disconnection to the handset; or the mobile phone can also automatically detect whether the connection with the earplug is disconnected. For the channel parameters, the earplug can measure the channel parameters of the link between the earplug and the mobile phone and report the channel parameters to the mobile phone; alternatively, the handset may itself detect the channel parameters of the link with the earpiece. For the electric quantity, the earplug can report the electric quantity of the earplug to the mobile phone. Whether the earplug detects voice data or not, if the earplug does not detect the voice data within a preset time length, the event can be reported to the mobile phone; or, the mobile phone can determine whether voice data sent by the earplug is received within a preset time period. After receiving the report message of the earplug, the mobile phone can return a confirmation message to the earplug to inform the earplug that the mobile phone has received the report message.

The first preset condition is, for example, a first earplug breaking. If the first earplug breaks the link, the second earplug is switched to provide voice data for telephone service of the mobile phone through MIC of the second earplug no matter what state the second earplug is in.

Still further exemplary, the first predetermined condition is that the first earplug is out of the ear. If the first earplug is out of the ear, the second earplug is switched to provide voice data for telephone service of the mobile phone through MIC of the second earplug no matter what state the second earplug is in.

And when the first earplug meets the first preset condition, the mobile phone or the TWS earphone can prompt the user that the first earplug has a problem through modes such as display, sound, vibration, indicator lamps and the like. For example, the first earpiece is a right earpiece, and when the first earpiece breaks the chain, see fig. 7, the phone prompts the user via prompt box 701 that the right earpiece has been disconnected from the phone by bluetooth.

The mobile phone switching to the MIC through the second earpiece to provide the voice data for the telephone service means that the mobile phone instructs the TWS earpiece to switch to the MIC through the second earpiece to provide the voice data for the telephone service. The manner in which the mobile phone instructs the TWS headset to switch is illustrated below by taking the first preset condition as an example of the first earplug out.

In one arrangement, when the first earpiece is out of the ear, the handset may automatically instruct/automatically control the switch to provide voice data for the telephone service via the MIC of the second earpiece.

In an exemplary embodiment, when the first earplug is in the out ear (i.e., the first preset condition is satisfied), the mobile phone may automatically instruct the second earplug to open the MIC, receive voice data collected by the MIC of the second earplug, perform phone service processing according to the voice data, and instruct the first earplug to close the MIC.

In another scheme, when the first earplug is out of the ear, the mobile phone can also prompt the user whether to switch, and after detecting a switching instruction of the user, the mobile phone instructs the TWS earphone to switch to provide voice data for telephone service of the mobile phone through the MIC of the second earplug.

For example, referring to fig. 8, the first ear plug is a right ear plug, the second ear plug is a left ear plug, and the mobile phone prompts the user whether to switch to providing voice data for the phone service of the mobile phone through the MIC of the second ear plug through a prompt box 801, if the mobile phone detects that the user clicks yes on the display screen, or the MIC of the mobile phone detects that the user indicates the switched voice data, the mobile phone indicates that the second ear plug opens the MIC, and indicates that the first ear plug closes the MIC.

Still further exemplary, the first earplug is a right earplug and the second earplug is a left earplug. Referring to fig. 9 (a), the mobile phone audibly prompts the user through the first earpiece and/or the second earpiece whether to switch to providing voice data for the phone service of the mobile phone through the MIC of the second earpiece. If the MIC of the first earplug detects a voice switching instruction input by a user, the voice switching instruction is sent to the mobile phone, and the mobile phone instructs the second earplug to open the MIC and instructs the first earplug to close the MIC. Alternatively, referring to (b) of fig. 9, if the mobile phone detects an input voice switching command through its own MIC, the mobile phone instructs the second earpiece to open the MIC and instructs the first earpiece to close the MIC.

The mobile phone automatic indication switching/automatic control switching or the mobile phone switching to the MIC of the second earplug according to the instruction of the user can be called mobile phone switching. The embodiment of the application mainly uses mobile phone switching as an example for illustration.

In case 1, referring to fig. 10, the step 504A may specifically include:

1001A, if the first earplug meets the first preset condition, the mobile phone instructs the second earplug to open the MIC, so that the MIC of the second earplug is switched from the closed state to the open state.

After the second earplug opens the MIC according to the indication of the mobile phone, a notification message may be sent to the mobile phone to enable the mobile phone to know and record that the MIC of the second earplug has been switched to an on state.

1002. The mobile phone receives voice data collected by the MIC of the second earplug.

Specifically, the mobile phone may receive, through a second bluetooth connection with the second earpiece, voice data sent by the second earpiece and collected by the MIC of the second earpiece.

1003. And the mobile phone performs telephone service processing according to the voice data acquired by the MIC of the second earplug.

1004. The handset instructs the first earpiece to close the MIC.

In step 1004, after the mobile phone instructs the first earpiece to close the MIC, the mobile phone may still send audio data to the first earpiece, and the user may still hear the voice data of the opposite end of the phone through the first earpiece. It should be noted that, if the first preset condition includes the first earplug breaking, after step 1001A, the mobile phone may not need to execute step 1004, and the first earplug may close the MIC by itself.

After step 1001A, the mobile phone may receive a message sent by the second earpiece that the MIC of the second earpiece is opened, and after receiving the message that the MIC of the second earpiece is opened, instruct the first earpiece to close the MIC.

Or the mobile phone instructs the first earplug to close the MIC after receiving the voice data acquired by the MIC of the second earplug.

After the first earpiece closes the MIC, a notification message may be sent to the handset to cause the handset to learn and record that the MIC of the first earpiece has been switched to the closed state.

In case 1, when the MIC of the first earplug is switched to the MIC of the second earplug to provide voice data for the telephone service of the mobile phone, the MIC of the second earplug can be opened first, and then the MIC of the first earplug is closed, so that the voice data of the user can be provided to the mobile phone uninterruptedly, and interruption of the voice data is avoided. And the MIC of the first earplug is closed in time after the switching, so that the power consumption of the first earplug can be saved.

In another embodiment, the first earplug meeting the switching condition in step 504 may include the first earplug meeting a first preset condition and the second earplug meeting a second preset condition. That is, referring to fig. 5, step 504 may specifically include:

504B, if the first earplug meets the first preset condition and the second earplug meets the second preset condition, the mobile phone performs phone service processing according to the voice data collected by the MIC of the second earplug.

Accordingly, referring to fig. 10, step 1001A of steps 1001A-1003 described above may be replaced with:

1001B, if the first earplug meets the first preset condition and the second earplug meets the second preset condition, the mobile phone instructs the second earplug to open the MIC, so that the MIC of the second earplug is switched from the closed state to the open state.

Wherein the second preset condition may include one or more of: in-ear (in the ear), bluetooth connection is saved with the mobile phone, the electric quantity is larger than or equal to a second preset value, and the channel quality of a link between the mobile phone and the mobile phone is higher than or equal to a third preset value.

When the first earplug meets the first preset condition, it may indicate that the first earplug has a problem, and the MIC of the first earplug may not normally provide voice data for phone service of the mobile phone. If the second earplug meets the second preset condition, the MIC of the second earplug may be indicated to be able to normally provide voice data for the phone service of the mobile phone, so that the mobile phone may switch to provide voice data for the phone service through the MIC of the second earplug, and thus phone service processing is performed according to the voice data collected by the MIC of the second earplug. Wherein the mobile phone being switchable to provide voice data for the telephone service through the MIC of the second earpiece means that the mobile phone instructs the TWS earpiece to switch to provide voice data for the telephone service through the MIC of the second earpiece.

In this embodiment, if the first earplug meets the first preset condition and the second earplug does not meet the second preset condition, the MIC of the first earplug may be continuously used to provide voice data for the phone service of the mobile phone. Or if the first earplug meets the first preset condition and the second earplug does not meet the second preset condition, the user can be prompted by the mobile phone or the TWS earphone that the TWS earphone has a problem, and the TWS earphone is stopped to provide voice data for telephone service of the mobile phone.

In a specific embodiment, if the first earplug meets the first preset condition, it may indicate that the first earplug has a problem, and at this time, whether the second earplug also has the same problem as the first earplug, as long as the second earplug meets the second preset condition, and the second preset condition is that the second earplug is connected with the mobile phone through bluetooth, the second preset condition may be switched to provide voice data for the phone service of the mobile phone through the MIC of the other earplug, so that the mobile phone can process the phone service normally or better.

That is, when the first earplug meets the first preset condition, and the problems of ear out, chain breakage, low power, poor channel quality, or no voice data playing and no voice data collecting occur within the preset time period, and the like, if the second earplug is connected with the mobile phone by bluetooth, the mobile phone can switch to provide voice data for the telephone service of the mobile phone through the MIC of the second earplug. If the second earplug and the mobile phone are disconnected, the mobile phone does not switch MIC, and the MIC of the first earplug is still used for providing voice data for telephone service of the mobile phone.

For example, the first preset condition includes that the first earplug is disconnected from the mobile phone, and the second preset condition is that the second earplug is connected with the mobile phone in a Bluetooth mode. When the first earplug breaks the link with the mobile phone, the MIC of the first earplug can not normally provide voice data for the telephone service of the mobile phone; at this time, if the second earplug is connected to the mobile phone through bluetooth, the mobile phone may switch to MIC of the second earplug to provide voice data for the phone service.

For another example, the first preset condition includes that the first earplug does not play voice data and does not collect voice data within a preset time period, and the second preset condition includes that the second earplug is in Bluetooth connection with the mobile phone. The preset time length can be set according to actual needs, for example, 10 seconds. If the MIC of the first earplug does not play the voice data of the opposite terminal within the preset time, the local user may speak, and if the mobile phone does not collect the voice data within the preset time, the mobile phone does not receive the voice data provided by the MIC of the first earplug within the preset time, the MIC of the first earplug may be damaged or the first earplug may be damaged so as to be unable to be used normally. At this time, if the second earplug is connected to the mobile phone through bluetooth, the mobile phone may switch to provide voice data for the phone service of the mobile phone through MIC of the second earplug.

For another example, the first preset condition includes that a channel quality of a link between the first earpiece and the mobile phone is lower than a third preset value, and the second preset condition includes that the second earpiece maintains a bluetooth connection with the mobile phone. When the channel quality of the link between the first earplug and the mobile phone is lower than a third preset value, the quality of voice data provided by the first earplug for the telephone service of the mobile phone is lower. At this time, if the second earplug is connected to the mobile phone through bluetooth, the mobile phone may switch to provide voice data for the phone service of the mobile phone through MIC of the second earplug.

For another example, the first preset condition includes that the first earplug protrudes out of the ear, and the channel quality of the link between the first earplug and the mobile phone is lower than a third preset value; the second preset condition includes that the second earplug is in Bluetooth connection with the mobile phone. When the first earpiece is out of the ear and the channel quality of the link between the first earpiece and the handset is below a third preset value, for example, the user may place the MIC of the first earpiece in the mouth to speak, but the MIC of the first earpiece provides lower quality voice data for the phone service of the handset. At this time, if the second earplug is connected to the mobile phone by bluetooth, the mobile phone may switch to provide voice data for the phone service of the mobile phone through the MIC of the second earplug if the second earplug is connected to the mobile phone by bluetooth.

For another example, the first preset condition includes that the electric quantity of the first earplug is smaller than a second preset value, and the second preset condition includes that Bluetooth connection is kept between the second earplug and the mobile phone. When the electric quantity of the first earplug is smaller than the second preset value, the electric quantity of the first earplug is lower, the first earplug can stop working at any time, and the MIC of the first earplug can not normally provide voice data for telephone service of the mobile phone. In one scheme, the first earplug can report to the mobile phone when the electric quantity is smaller than a second preset value; in another scheme, the mobile phone can monitor the electric quantity of the first earplug, so that whether the electric quantity of the first earplug is smaller than a second preset value or not can be conveniently obtained. At this time, if the second earplug is connected to the mobile phone through bluetooth, the mobile phone may switch to provide voice data for the phone service of the mobile phone through MIC of the second earplug.

In another embodiment, if the first earplug meets the first preset condition, it may indicate that the first earplug has a problem, and voice data may not be normally provided for phone service of the mobile phone. At this time, if the second earplug does not have the same problem, the method may switch to providing voice data for the phone service of the mobile phone through the MIC of the second earplug. When the first earplug meets a first preset condition and the second earplug meets a second preset condition, the second preset condition comprises a first sub-condition, and the first sub-condition is a condition opposite to the first preset condition, the second earplug has no problem same as the first earplug.

And, the second preset condition may further include a second sub-condition, where the second sub-condition is that the second earplug is kept connected with the mobile phone by bluetooth. Wherein the first sub-condition may include at least one of: in order to enter the ear (i.e. the state of being placed in the ear), the electric quantity is larger than or equal to a second preset value, the channel quality of a link between the electric quantity and the mobile phone is higher than or equal to a third preset value, and voice data are collected within a preset time period.

For example, the first preset condition includes that the first earplug is out of the ear, the second preset condition includes that the second earplug is in Bluetooth connection with the mobile phone, and the second earplug is in an in-ear (in-ear) state. If the first earplug comes out of the ear, the first earplug may be dropped carelessly, or the user may take the first earplug out of the ear, and the first earplug may not normally provide voice data for voice service of the mobile phone. If the second earplug is connected with the mobile phone by Bluetooth and the second earplug is in an in-ear state, that is, the second earplug is still in the ear, the mobile phone can switch to provide voice data for voice service of the mobile phone through MIC of the second earplug.

For another example, the first preset condition includes that the first earplug is out of the ear, the second preset condition includes that Bluetooth connection is kept between the second earplug and the mobile phone, the second earplug is in an in-ear state, and the electric quantity of the second earplug is larger than or equal to a second preset value. That is, if the first earplug is out of the ear, the first earplug may be inadvertently dropped, or the user may remove the first earplug from the ear, and the first earplug may not be able to normally provide voice data for phone service of the mobile phone. At this time, if the second earplug is connected to the mobile phone by bluetooth, the second earplug is still in the ear, and the electric quantity of the second earplug is greater than or equal to the second preset value (i.e. the electric quantity of the second earplug is sufficient), the mobile phone can switch to provide voice data for the phone service of the mobile phone through the MIC of the second earplug.

For another example, the first preset condition includes that the electric quantity of the first earplug is smaller than a second preset value, the second preset condition includes that bluetooth connection is kept between the second earplug and the mobile phone, and the electric quantity of the second earplug is larger than or equal to the second preset value. When the electric quantity of the first earplug is smaller than the second preset value, the electric quantity of the first earplug is lower, the first earplug can stop working at any time, and the MIC of the first earplug can not normally provide voice data for telephone service of the mobile phone. At this time, if the second earplug is connected to the mobile phone by bluetooth, and the electric quantity of the second earplug is greater than or equal to the second preset value, the electric quantity of the second earplug is sufficient, and the mobile phone can switch to provide voice data for the phone service of the mobile phone through the MIC of the second earplug.

For another example, the first preset condition includes that the electric quantity of the first earplug is smaller than a second preset value, the second preset condition includes that bluetooth connection is kept between the second earplug and the mobile phone, the electric quantity of the second earplug is larger than or equal to the second preset value, and the channel quality of a link between the second earplug and the mobile phone is higher than or equal to a third preset value. When the power of the first earpiece is low, the MIC of the first earpiece may not normally provide voice data for the phone service of the mobile phone. If the second earplug is connected with the mobile phone by Bluetooth, the electric quantity of the second earplug is sufficient, and the channel quality of the link between the second earplug and the mobile phone is high, the mobile phone can be switched to provide voice data with higher quality for telephone service of the mobile phone through MIC of the second earplug.

For another example, the first preset condition includes that an electric quantity of the first earplug is smaller than a second preset value, and a channel quality of a link between the second earplug and the mobile phone is lower than a third preset value. The second preset condition includes that Bluetooth connection is kept between the second earplug and the mobile phone, the electric quantity of the second earplug is larger than or equal to a second preset value, and the channel quality of a link between the second earplug and the mobile phone is higher than or equal to a third preset value. That is, if the power of the first earpiece is low and the channel quality of the link between the second earpiece and the handset is low, the MIC of the first earpiece may not be suitable to continue to provide voice data for the phone service of the handset. At this time, if the second earplug is connected with the mobile phone by bluetooth, the electric quantity of the second earplug is sufficient, and the channel quality of the link between the second earplug and the mobile phone is higher, the MIC of the second earplug can be switched to better provide voice data for the telephone service of the mobile phone.

For another example, the first preset condition includes that the ear-out time of the first earplug is greater than or equal to a first preset value, the second preset condition includes that the second earplug is in Bluetooth connection with the mobile phone, and the second earplug is in an in-ear state. If the first earplug out-of-ear time is greater than or equal to the first preset value, the first earplug may fall for a longer time, or the user does not want to use the first earplug any more, and the MIC of the first earplug cannot normally provide voice data for telephone service of the mobile phone. If the second earpiece is connected to the phone by bluetooth and the second earpiece is still in the ear, the phone may switch to providing voice data for phone service of the phone through MIC of the second earpiece.

For another example, the first preset condition includes that the first earplug is out of the ear, and the channel quality of the link between the first earplug and the mobile phone is lower than a third preset value. The second preset condition includes maintaining a bluetooth connection between the second earpiece and the handset, the channel quality of the link between the second earpiece and the handset being higher than or equal to a third preset value. That is, if the first earpiece is not in the ear, but the MIC of the first earpiece collects voice data and the channel quality of the link between the first earpiece and the handset is poor, the user may be speaking with the first earpiece in the mouth, but the MIC of the first earpiece may not provide better quality voice data to the handset. If the channel quality of the link between the second earpiece and the handset is high, the MIC of the second earpiece may better provide voice data for the phone service of the handset and thus may be switched to the MIC of the second earpiece to provide voice data.

In another embodiment, the first earpiece in step 504 meeting the switching condition may include a state parameter of the first earpiece being worse than a state parameter of the second earpiece. That is, referring to fig. 5, step 504 may specifically include:

504C, if the state parameter of the first earplug is worse than the state parameter of the second earplug, the mobile phone performs phone service processing according to the voice data collected by the MIC of the second earplug.

1001C, if the state parameter of the first earplug is worse than the state parameter of the second earplug, the mobile phone instructs the second earplug to open the MIC, so that the MIC of the second earplug is switched from the closed state to the open state.

The status parameters of the earplug may include, among other things, whether the earplug remains connected to the phone, whether the earplug is in the ear, the amount of power of the earplug, the channel quality of the link between the earplug and the phone, etc. For example, when a first earpiece is disconnected from the phone and a second earpiece remains connected to the phone, the state parameter of the first earpiece is worse than the state parameter of the second earpiece, which is better than the state parameter of the first earpiece. For another example, when the first earplug exits the ear and the second earplug enters the ear, the state parameter of the first earplug is worse than the state parameter of the second earplug, which is better than the state parameter of the first earplug. For another example, when the power of the first earpiece is lower than the power of the second earpiece, the status parameter of the first earpiece is worse than the status parameter of the second earpiece, which is better than the status parameter of the first earpiece. For another example, when the channel quality of the link between the first earpiece and the handset is lower than the channel quality of the link between the second earpiece and the handset, the state parameter of the first earpiece is worse than the state parameter of the second earpiece, which is better than the state parameter of the first earpiece.

For example, the switching condition may include the power of the first earpiece being less than the power of the second earpiece. When the electric quantity of the first earplug is smaller than that of the second earplug, the mobile phone can be switched to provide voice data for voice service through the MIC of the second earplug.

Still further exemplary, the switching condition may include the power of the first earpiece being less than the power of the second earpiece, and the channel quality of the link between the first earpiece and the handset being lower than the channel quality of the link between the second earpiece and the handset. When the switching condition is satisfied, the mobile phone can switch to provide voice data for the voice service through the MIC of the second earplug.

In another embodiment, if the first earplug has a problem, the second earplug has the same problem, but other state parameters corresponding to the second earplug are better than those corresponding to the first earplug, the method switches to provide voice data for telephone service of the mobile phone through MIC of the second earplug. That is, the first earplug meets a first preset condition, the second earplug meets the first preset condition and a second preset condition, and the second preset condition includes that other state parameters corresponding to the second earplug are better than other state parameters corresponding to the first earplug. The other state parameters referred to herein refer to state parameters other than those to which the first preset condition relates. In this embodiment, if the other state parameters corresponding to the second earplug are worse than the other state parameters corresponding to the first earplug, the MIC is not switched.

For example, if the first earplug is out (i.e., the first earplug meets the first preset condition), the second earplug is also out (i.e., the second earplug meets the first preset condition), but the power of the second earplug is higher than the power of the first earplug, or the channel quality of the link between the second earplug and the mobile phone is higher than the channel quality of the link between the first earplug and the mobile phone (i.e., the second earplug meets the second preset condition), the method switches to providing voice data for the phone service of the mobile phone through the MIC of the second earplug. In this way, the second earpiece has better state parameters than the first earpiece, is better suited for providing voice data for phone traffic of the handset, and thus can switch MIC.

For example, if the first earplug leaves the ear (i.e., the first earplug meets the first preset condition), the second earplug also leaves the ear (i.e., the second earplug meets the first preset condition), but the electric quantity of the second earplug is lower than that of the first earplug (i.e., other state parameters corresponding to the second earplug are worse than those corresponding to the first earplug), the MIC is not switched, and voice data is still provided for telephone service of the mobile phone through the MIC of the first earplug. In this way, the first earpiece has better state parameters than the second earpiece, and is better suited for providing voice data for phone traffic of the handset, so that the MIC may not be switched.

In another embodiment, if the first earpiece presents a problem and the second earpiece presents the same problem, the MIC is not switched, and voice data is still provided for phone service of the mobile phone through the MIC of the first earpiece.

For example, if both the first earplug and the second earplug meet the first preset condition, it may be indicated that the same problem occurs with both the second earplug and the first earplug.

For example, if the first earplug leaves the ear (i.e., the first earplug meets the first preset condition), the second earplug also leaves the ear (i.e., the second earplug meets the first preset condition), the MIC is not switched, and voice data is still provided for the phone service of the mobile phone through the MIC of the first earplug. For another example, if the electric quantity of the first earplug is lower than the second preset value and the electric quantity of the second earplug is also lower than the second preset value, the MIC is not switched, and voice data is still provided for the telephone service of the mobile phone through the MIC of the first earplug.

In another embodiment, if the first earplug has a problem, the second earplug does not have the same problem, but the second earplug has another problem, the MIC is not switched, and the MIC of the first earplug is still used to provide voice data for phone service of the mobile phone.

If the first earplug is in the in-ear state, but the electric quantity of the second earplug is lower than the second preset value, the MIC is not switched, and the MIC of the first earplug is still used for providing voice data for telephone service of the mobile phone.

In another embodiment, when the first earpiece is out of the ear and the channel quality of the link between the first earpiece and the handset is higher than the channel quality of the link between the second earpiece and the handset, the user may be talking with the first earpiece at the mouth, so that the MIC of the second earpiece need not be switched to provide voice data for the phone service of the handset, although the first earpiece is out of the ear.

It should be noted that, the above embodiment is described taking, as an example, the mobile phone instructs the MIC of the second earplug to be switched to provide voice data for the telephone service when the switching condition is satisfied. In another aspect, if a wireless connection (e.g., a bluetooth connection, an NFMI connection, etc.) is provided between the first earpiece and the second earpiece, the TWS earpiece may also automatically switch from the MIC of the first earpiece to the MIC of the second earpiece to provide voice data for the phone service of the handset.

When the first earplug and the second earplug are in wireless connection, the electric quantity of each earplug can be interacted between the first earplug and the second earplug through the wireless connection, the channel quality of a link between each earplug and the mobile phone, whether each earplug is out of the ear, whether the link between each earplug and the mobile phone is broken or not and the like.

Illustratively, in step 504B, the first preset condition includes a first earplug out of the ear; the second preset condition includes that the second earplug is connected with the mobile phone in a Bluetooth mode, and the second earplug is in an in-ear state. After the first earplug leaves the ear (i.e. the first preset condition is met), the first earplug may send a notification message 1 to the second earplug; when the second earplug is in an in-ear state, bluetooth connection with the mobile phone is maintained (namely, a second preset condition is met), and after the notification message 1 is received, the MIC of the second earplug can be opened, and the notification message 2 is sent to the first earplug; after the first earpiece receives the notification message 2, the MIC of the first earpiece may be turned off.

In another scheme, the TWS earphone may also prompt the user whether to switch, and after the TWS earphone detects the switching instruction of the user, the TWS earphone switches to provide voice data for the phone service of the mobile phone through the MIC of the second earplug.

In this scenario, in step 504B, the first preset condition includes a first earplug out; the second preset condition includes that the second earplug is connected with the mobile phone in a Bluetooth mode, and the second earplug is in an in-ear state. The first earplug meets the first preset condition, and the second earplug meets the second preset condition is described as an example:

The first earpiece and/or the second earpiece illustratively voice prompts the user whether to switch to providing voice data for telephony services of the handset via the MIC of the second earpiece. If the second earpiece detects a first manipulation by the user on the second earpiece, the second earpiece opens the MIC. The second earpiece then notifies the first earpiece to close the MIC, or if the first earpiece detects a second operation by the user on the first earpiece, the first earpiece closes the MIC.

For example, the first earpiece and the second earpiece may have MIC switches thereon, the first operation may be a user click operation on the MIC switch of the first earpiece, and the second operation may be a user click operation on the MIC switch of the second earpiece. In another example, the first operation may be an operation of the user shaking the first earpiece and the second operation may be an operation of the user shaking the second earpiece. For example, when a user nods his head, the first ear plug and the second ear plug shake to switch the MIC on and off, i.e. the second ear plug opens the MIC and the first ear plug closes the MIC.

In an exemplary embodiment, a wireless connection is established between the first earpiece and the second earpiece, and the first earpiece and/or the second earpiece voice prompts the user whether to switch to providing voice data for telephony services of the handset via the MIC of the second earpiece. Referring to fig. 11A, the first earpiece is a right earpiece, a MIC switch 1101 is provided on the first earpiece, when the first earpiece detects that the user touches the operation of the MIC switch 1101, the first earpiece notifies the second earpiece to open the MIC, and the first earpiece closes the MIC.

Still further exemplary, a wireless connection is established between the first earpiece and the second earpiece, the first earpiece and/or the second earpiece audibly prompting the user whether to switch to providing voice data for telephony services of the handset through the MIC of the second earpiece. If the MIC of the first earplug detects a voice switching instruction of the user, the first earplug informs the second earplug of opening the MIC through Bluetooth connection with the second earplug, and the first earplug closes the MIC.

The above-mentioned audio means of prompting the user may be from a mobile phone or in a pre-existing earplug.

Still further exemplary, a wireless connection is established between the first earpiece and the second earpiece, see fig. 11B, the first earpiece being the left earpiece, the first earpiece prompting the user "switch MIC? ". If the display screen detects touch operation of a user, the first earplug informs the second earplug of opening the MIC through Bluetooth connection between the first earplug and the second earplug, and the first earplug closes the MIC; if the touch operation of the user is not detected, the MIC is not switched. Or triggering the second earplug to open the MIC by double-click operation, if the display screen detects double-click operation of a user, the first earplug informs the second earplug to open the MIC through Bluetooth connection with the second earplug, and the first earplug closes the MIC; if the display screen does not detect the double click operation of the user, the MIC is not switched.

It should be noted that, the ways in which the TWS earphone prompts the user to switch to the MIC of the other earplug may also be multiple, for example, by vibration, by an indicator light, or by a combination of the above-mentioned prompting ways; the manner in which the user indicates the switch may also be varied, and the embodiments of the present application will not be described in detail.

Case 2: when the mobile phone carries out telephone service processing according to voice data collected by the MIC of the first earplug, the MIC of the second earplug is also in an open state.

After the mobile phone establishes bluetooth connection with the first earplug and the second earplug, the MIC of the first earplug and the MIC of the second earplug may be in a closed state by default, and the mobile phone may indicate to open the MIC of the first earplug and the MIC of the second earplug. The MIC of the first earpiece and the MIC of the second earpiece both collect voice data. The first earplug and the second earplug respectively send the voice data acquired by the MIC to the mobile phone through Bluetooth connection with the mobile phone. And the mobile phone performs telephone service processing according to the voice data acquired by the MIC of the first earplug.

Alternatively, after the bluetooth connection is established between the mobile phone and the first and second earpieces, the MIC of the first earpiece and the MIC of the second earpiece may be in an on state by default. The MIC of the first earpiece and the MIC of the second earpiece both collect voice data. The first earplug and the second earplug respectively send the voice data acquired by the MIC to the mobile phone through Bluetooth connection with the mobile phone. And the mobile phone performs telephone service processing according to the voice data acquired by the MIC of the first earplug.

That is, in case 2, the MIC of two TWS earplugs is in an on state, and the mobile phone may receive two voice data collected by two MIC, but performs phone service processing according to only one voice data collected by one MIC.

In case 2, as in case 1, when the first earplug meets the first preset condition and the second earplug meets the second preset condition, the method may switch to providing voice data for phone service of the mobile phone through MIC of the second earplug.

In an embodiment, the first preset condition and the second preset condition in case 2 may be the same as the first preset condition and the second preset condition in case 1.

In another embodiment, in case 2, the first preset condition may further include that the first earplug does not play the voice data and does not collect the voice data for a preset time period. The second preset condition may further include that the second earplug does not play the voice data for a preset period of time but collects the voice data.

For example, the first preset condition includes that the first earplug does not play voice data and does not collect voice data within a preset time period; the second preset condition comprises that Bluetooth connection is kept between the second earplug and the mobile phone, the second earplug does not play voice data within a preset time period, and the second earplug collects the voice data within the preset time period. If the first earplug does not play the voice data within the preset time period and the MIC of the first earplug does not collect the voice data within the preset time period, the MIC of the first earplug may be damaged; if the second earplug is connected with the mobile phone by Bluetooth and the second earplug does not play voice data within a preset time, the second earplug collects the voice data within the preset time, the MIC of the second earplug can be normally used, and therefore the MIC of the second earplug can be switched to provide voice data for telephone service.

For another example, the first preset condition includes that the first earplug is out of the ear, and the first earplug does not collect voice data within a preset time period. The second preset condition comprises that Bluetooth connection is kept between the second earplug and the mobile phone, the second earplug is in an in-ear state, voice data are not played by the second earplug in a preset time period, but voice signals are collected, the electric quantity of the second earplug is larger than or equal to a second preset value, and the channel quality of a link between the second earplug and the mobile phone is higher than or equal to a third preset value. That is, if the first earpiece is not in the ear and no voice data is collected for a preset period of time, the first earpiece may not be beside the user and the MIC of the first earpiece may not normally provide voice data to the cell phone. At this time, if the second earpiece is in the ear and the second earpiece has sufficient power and the channel quality of the link between the second earpiece and the handset is high, then a switch may be made to better provide voice data for the phone service of the handset through the MIC of the second earpiece.

In another embodiment, in case 2, the state parameter of the first earplug is worse than the state parameter of the second earplug, and the first earplug plays the voice data and does not collect the voice data within a preset time period, and the second earplug does not play the voice data and does not collect the voice data within the preset time period.

In case 2, when the phone service processing needs to be switched to the phone service processing through the MIC of the second earplug, the phone or the TWS earphone may be automatically switched to the phone service processing through the MIC of the second earplug, as in case 1. Or the mobile phone or the TWS earphone can also prompt the user whether to switch, and after the switching instruction of the user is detected, the mobile phone or the TWS earphone is switched to provide voice data for telephone service of the mobile phone through the MIC of the second earplug.

For example, in the scheme shown in step 504B, when the first earplug meets the first preset condition and the second earplug meets the second preset condition, the mobile phone automatically performs phone service processing according to the voice data collected by the MIC of the second earplug, and stops performing phone service processing according to the voice data collected by the MIC of the first earplug.

For another example, in the scheme shown in step 504B, when the first earplug meets the first preset condition and the second earplug meets the second preset condition, the mobile phone prompts the user through the voice of the first earplug and/or the second earplug, and whether to switch to provide voice data for the phone service of the mobile phone through the MIC of the second earplug. If the first earplug or the second earplug detects the MIC of the user voice indication switching earplug, the first earplug or the second earplug informs the mobile phone, and telephone service processing is carried out according to voice data acquired by the MIC of the second earplug.

It should be further noted that, in case 2, since the MIC of both earplugs is in an open state, when the MIC of voice data is provided for the phone service of the mobile phone, the voice data provided for the phone service of the mobile phone is not interrupted in the process of switching from the MIC of the first earplug to the MIC of the second earplug.

In case 2, after switching to providing voice data to the phone service of the mobile phone through the MIC of the second earpiece, in one scheme, unlike in case 1, the MIC of the first earpiece may be kept in an on state. That is, referring to fig. 12, before step 503 in fig. 5, the method may further include: 1201. the mobile phone receives voice data collected by the MIC of the second earplug. Specifically, the mobile phone may receive, through a second bluetooth connection with the second earpiece, voice data sent by the second earpiece and collected by the MIC of the second earpiece.

Step 504A in fig. 5 may include:

1202A, if the first earplug meets the first preset condition, the mobile phone performs phone service processing according to the voice data collected by the MIC of the second earplug.

1203. The mobile phone stops the telephone service processing according to the voice data collected by the MIC of the first earplug.

Step 1201A may also be replaced with step 1202B or step 1202C, corresponding to step 504B and step 504C in fig. 5:

1202B, if the first earplug meets the first preset condition and the second earplug meets the second preset condition, the mobile phone performs phone service processing according to voice data acquired by the MIC of the second earplug.

1202C, if the state parameter of the first earplug is worse than the state parameter of the second earplug, the mobile phone performs phone service processing according to the voice data collected by the MIC of the second earplug.

In case 2, after switching to providing voice data to the phone service of the mobile phone through the MIC of the second earpiece, i.e. after step 1203, the mobile phone may also instruct the first earpiece to close the MIC in another scenario.

In other embodiments of the present application, when the first earplug has a low power, a poor channel quality of a link with the mobile phone, or the first earplug has a problem of coming out of the ear, but both the first earplug and the second earplug are connected with the mobile phone by bluetooth, the MIC of the first earplug and the MIC of the second earplug can simultaneously provide voice data for a phone service of the mobile phone.

In other embodiments of the present application, the two earplugs of the TWS headset have a split of the primary earplug and the secondary earplug in a two-shot approach. The mobile phone can firstly process telephone service according to the voice data collected by the main earplug. When the primary earplug (for example, the first earplug) meets the switching condition, the mobile phone can inform the primary earplug and the secondary earplug of switching primary roles and secondary roles, switch the original secondary earplug (for example, the second earplug) to be a new primary earplug, switch the original primary earplug (for example, the first earplug) to be a new secondary earplug, and provide voice data for the mobile phone by adopting the switched new primary earplug (for example, the second earplug), so that the mobile phone can perform telephone service processing. Namely, the mobile phone always carries out telephone service processing according to the voice data collected by the main earplug.

After the two-way connection is established and the main earplug and the auxiliary earplug are determined, the MIC of the main earplug is in an open state, the MIC of the auxiliary earplug is in a closed state, and the mobile phone performs telephone service processing according to voice data acquired by the MIC of the main earplug corresponding to the situation 1. Corresponding to the above case 2, the MIC of the main earplug and the MIC of the auxiliary earplug are both in an on state, and the mobile phone performs phone service processing according to the voice data collected by the MIC of the main earplug. Then, referring to the process described in the above embodiment, when the switching condition is satisfied, the roles of the main earplug and the auxiliary earplug can be switched, and the mobile phone performs phone service processing according to the voice data collected by the MIC of the main earplug after the switching.

For example, in case 1, referring to fig. 13, before step 503, the method may further include: 1300. the mobile phone determines a main earplug and an auxiliary earplug, wherein the first earplug is the main earplug, and the second earplug is the auxiliary earplug. The manner in which the mobile phone determines the main earplug can be varied. For example, the primary earplug may be determined with reference to the above specific implementation manner of determining the target earplug according to the preset policy, and another earplug other than the primary earplug is a secondary earplug, which is not described herein. Step 502 may specifically include: 1301. the mobile phone receives voice data sent by the main earplug. Step 503 may specifically include: 1302. the mobile phone processes telephone service according to the voice data collected by the main earplug (namely the first earplug). Step 504 may specifically include: 1303A, if the first earplug (i.e. the main earplug) meets the first preset condition, the mobile phone sends information 1 (i.e. the first information) to the second earplug (i.e. the auxiliary earplug), so that the second earplug is switched to the main earplug and the MIC is opened, and the MIC of the second earplug is switched from the closed state to the open state; and sends information 2 (i.e., second information) to the first earpiece to cause the first earpiece to switch to the secondary earpiece and to close the MIC such that the MIC of the first earpiece switches from an on state to an off state. 1304. And the mobile phone receives the voice data sent by the switched main earplug. 1305. And the mobile phone processes telephone service according to the voice data acquired by the switched main earplug.

Wherein, the information 1 may be used to instruct the second earpiece to switch to the master earpiece and instruct the second earpiece to open the MIC; alternatively, information 1 may be used to instruct the second earpiece to switch to the master earpiece, which automatically opens the MIC. After receiving the information 1 sent by the mobile phone, the second earplug can be switched to the main earplug first and then the MIC is opened; or the second earpiece may first open the MIC and then switch to the master earpiece.

Specifically, the earplug can store first identification information for indicating the identity of the main earplug or second identification information for indicating the identity of the auxiliary earplug, and when the earplug updates the first identification information into the second identification information, the earplug is switched from the main earplug to the auxiliary earplug; when the earplug updates the second identification information to the first identification information, the earplug is switched from the auxiliary earplug to the main earplug.

Information 2 may be used to indicate that the first earpiece is switched to the secondary earpiece and that the first earpiece is turned off the MIC; alternatively, information 2 may be used to indicate that the first earpiece is switched to the secondary earpiece, which automatically closes the MIC. After receiving the information 2 sent by the mobile phone, the first earplug can close the MIC first and then switch to be a secondary earplug; or the first earpiece may be switched to the secondary earpiece before closing the MIC.

It should be noted that, for the step of transmitting the information 2 by the mobile phone in the step 1303A, the mobile phone may specifically transmit the information 2 to the first earplug before the steps 1304-1305, or may transmit the information 2 to the first earplug after the steps 1304-1305, which is not limited in the embodiments of the present application.

The step 1303A may be replaced by a step 1303B or a step 1303C:

1303B, if the first earplug (i.e. the main earplug) meets the first preset condition and the second earplug (i.e. the auxiliary earplug) meets the second preset condition, the mobile phone sends information 1 to the second earplug, so that the second earplug is switched to the main earplug and the MIC is opened; and sends a message 2 to the first earpiece to cause the first earpiece to switch to the secondary earpiece and close the MIC.

1303C, if the status parameter of the first earplug (i.e. the main earplug) is worse than the status parameter of the second earplug (i.e. the auxiliary earplug), the mobile phone sends information 1 to the second earplug, so that the second earplug is switched to the main earplug and the MIC is opened; and sends a message 2 to the first earpiece to cause the first earpiece to switch to the secondary earpiece and close the MIC.

In step 1303A, step 1303B, or step 1303C, the second earpiece may also send a notification message to the mobile phone after opening the MIC, so that the mobile phone knows and records that the MIC of the second earpiece has been switched to the on state. After the MIC of the first earpiece is closed, a notification message may also be sent to the handset to cause the handset to learn and record that the MIC of the first earpiece has been switched to the closed state.

Referring to fig. 14, in case 2, on the basis of steps 500, 1300, 1301, 1302, and 1303A, 1303B, or 1303C shown in fig. 13, step 1303A in fig. 13 may be replaced with 1403A, step 1303B may be replaced with 1403B, and step 1303C may be replaced with 1403C).

1403A, if the first earplug (i.e. the master earplug) meets the first preset condition, the mobile phone sends information 3 to the second earplug to instruct the second earplug to switch to the master earplug; and sends information 4 to the first earpiece to instruct the first earpiece to switch to the secondary earpiece.

1403B, if the first earplug (i.e. the main earplug) meets the first preset condition and the second earplug (i.e. the auxiliary earplug) meets the second preset condition, the mobile phone sends information 3 to the second earplug to instruct the second earplug to switch to the main earplug; and sends information 4 to the first earpiece to instruct the first earpiece to switch to the secondary earpiece.

1403C, if the state parameter of the first earplug (i.e. the main earplug) is worse than the state parameter of the second earplug (i.e. the auxiliary earplug), the mobile phone sends information 3 to the second earplug, and the mobile phone sends information 3 to the second earplug to instruct the second earplug to switch to the main earplug; and sends information 4 to the first earpiece to instruct the first earpiece to switch to the secondary earpiece.

Also, in case 2, since the MICs of both earplugs are in the on state, step 1402 may also be performed before step 1403A, step 1403B, or step 1403C: the mobile phone receives voice data collected by MIC of the auxiliary earplug.

After step 1403A, step 1403B or step 1403C, the mobile phone may perform step 1404: and the mobile phone processes telephone service according to the voice data acquired by the switched main earplug.

Optionally, after step 1403A, step 1403B or step 1403C, the mobile phone may further notify the first earplug to close the MIC, so that the MIC of the first earplug is switched from the on state to the off state. After the MIC of the first earplug is closed, a notification message may also be sent to the mobile phone to enable the mobile phone to know and record that the MIC of the first earplug has been switched to the closed state.

In the foregoing description, the two-way connection scheme between the mobile phone and the TWS earphone is mainly taken as an example, in other connection schemes such as monitoring, forwarding, and NFMI, when voice data is provided for a phone service of the mobile phone through the MIC of the first earplug, if the first earplug meets a first preset condition and the second earplug meets a second preset condition, the MIC of the second earplug may also be switched to provide voice data for the phone service of the mobile phone.

For example, the first preset condition may include one or more of a first earpiece out of the ear, a first earpiece low power, a MIC of the first earpiece not collecting voice data for a preset period of time, a low channel quality of a link between the first earpiece and the handset, and the like. The second preset condition may include one or more of the second earpiece being in an in-ear state, the second earpiece being sufficiently charged, a channel quality of a link between the second earpiece and the handset being high, etc.

For example, the TWS headset includes a right ear plug and a left ear plug, where in other connection schemes such as listening, forwarding, NFMI, etc., the right ear plug establishes a bluetooth connection with the mobile phone, the right ear plug is the main ear plug, the first ear plug is the right ear plug, the second ear plug is the left ear plug, and the MIC of the right ear plug provides voice data for the phone service of the mobile phone. When the right earplug meets the first preset condition and the left earplug meets the second preset condition, bluetooth connection with the left earplug is established, and then voice data is provided for telephone service of the mobile phone through MIC of the left earplug. Then, in one scheme, the mobile phone can keep the bluetooth connection with the right earplug, the right earplug is still the main earplug, and the MIC of the right earplug can be kept open or closed. In another scheme, the mobile phone can keep Bluetooth connection with the right earplug, the left earplug is switched to the main earplug, and the MIC of the right earplug can be kept on or closed; in another approach, the phone may disconnect the bluetooth connection with the right earpiece, the left earpiece being switched to the master earpiece.

For another example, the TWS headset includes a right earplug and a left earplug, where in other connection schemes such as monitoring, forwarding, NFMI, etc., the right earplug establishes a bluetooth connection with the mobile phone, the right earplug is a main earplug, the first earplug is a left earplug, the second earplug is a right earplug, and voice data collected by the MIC of the left earplug is forwarded to the mobile phone through the right earplug, so as to provide voice data for phone service of the mobile phone. When the left earplug meets the first preset condition and the right earplug meets the second preset condition, voice data can be provided for telephone service of the mobile phone through the MIC of the right earplug, and the MIC of the left earplug can be opened or closed.

It should be noted that, in the embodiment of the present application, after the mobile phone sends a message to the earplug, the earplug replies a response message to the mobile phone to notify the mobile phone earplug that the message sent by the mobile phone has been received, or notify the mobile phone earplug that the operation indicated by the message has been performed. Similarly, after the earplug sends a message to the mobile phone, the mobile phone also replies a response message to the earplug. For example, after the mobile phone sends the message 1 to the second earplug in step 1303A, the second earplug may send a response message to the mobile phone after receiving the message 1 to inform the mobile phone that the second earplug has received the message. For another example, after the mobile phone sends the information 1 to the second earplug in step 1303A, the second earplug receives the information 1 and opens the MIC, a response message may be sent to the mobile phone to notify the mobile phone that the second earplug has opened the MIC. For another example, after the earplug reports the electric quantity to the mobile phone, the mobile phone can reply a response message to inform the earplug that the mobile phone has received the electric quantity reported by the earplug.

In the foregoing, the phone service is mainly taken as a voice service for illustration, and in the voice service such as the WeChat audio/video call and the WeChat voice message, the mobile phone can switch the MIC by the method in the foregoing embodiment, which is not repeated in this application.
