Detailed Description

With the advancement of technology, TWS headphones gradually come into view of people. A TWS headset is a special bluetooth headset that includes two headset bodies, e.g., called left and right earplugs, respectively, and does not require a wire connection between the left and right earplugs.

Currently, the left and right earplugs of TWS headphones can be used as a pair of binaural headphones, or can be used alone. When the left earplug and the right earplug of the TWS earphone are used as a pair of double-ear earphones, the left earplug and the right earplug of the TWS earphone can be respectively connected with a mobile phone through Bluetooth. Based on the established bluetooth connection, the left and right earplugs of the TWS headset may be used as audio input/output devices of the handset to enable a call. Typically, Microphones (MICs) are included in both the left and right earplugs of a TWS headset. However, when the left and right earplugs of the TWS headset are used as an audio input/output device of a mobile phone to realize a call, only the microphone of one of the earplugs (such as the left or right earpiece) is turned on to collect a voice signal of a user.

The embodiment of the application provides a method for calling by using a Bluetooth headset, which is characterized in that when a user uses a left earplug and a right earplug of the TWS headset as audio input/output equipment of a mobile phone (such as a mobile phone 1) to realize calling, when other users want to access the calling through the mobile phone 1, microphones of the left earplug and the right earplug of the TWS headset can be turned on for collecting sound signals. Thus, the left earplug and the right earplug of the TWS earphone can be respectively used by two users (such as a user 1 and a user 3) to realize conversation. Thus, the user 1 and the user 3 can realize a three-person teleconference using the mobile phone 1 and the user 2 using the mobile phone 2 (the mobile phone which makes a call with the mobile phone 1 is referred to as the mobile phone 2).

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

As shown in fig. 2, the method for performing a call using a bluetooth headset according to the embodiment of the present application can be applied to a call system formed by a peripheral device 201, a first electronic device 202, and a second electronic device 203.

The first electronic device 202 can be used as one end of a call to communicate with the second electronic device 203. The peripheral device 201 and the first electronic device 202 may establish a bluetooth connection using bluetooth. Based on the established bluetooth connection, short-distance data interaction between the peripheral device 201 and the first electronic device 202 can be realized. When the user does not want to hold the first electronic device 202 to talk with the second electronic device 203, the first electronic device 202 may switch to the peripheral device 201 to talk. That is, based on the bluetooth connection, the peripheral device 201 and the first electronic device 202 may transmit voice data during a call, so that the peripheral device 201 is used as an audio input/output device of the first electronic device 202 to implement the call.

In some embodiments, the peripheral device 201 may be a TWS headset, bluetooth speaker, smart glasses, or the like. The peripheral 201 comprises two bodies and no wire connections are required between the two bodies. As an example, the peripheral device 201 shown in fig. 2 is illustrated as a TWS headset. The TWS headset includes two bodies (e.g., headset bodies), referred to as a left earbud 201-1 and a right earbud 201-2. The structure of the left and right earplugs 201-1 and 201-2 of the TWS headset may be as shown in FIG. 3 and will be described in detail in the following embodiments.

Wherein, the left earplug 201-1 and the right earplug 201-2 of the TWS headset may be used as a pair of binaural headsets to establish a bluetooth connection with the first electronic device 202. During the call, based on the established bluetooth connection, the first electronic device 202 may transmit voice data sent by the second electronic device 203 to the left ear plug 201-1 and the right ear plug 201-2 of the TWS headset for playing. When the user speaks, the TWS headset may collect corresponding sound signals and transmit to the first electronic device 202 after converting to voice data, so that the first electronic device 202 transmits the voice data to the second electronic device 203.

In this embodiment of the application, the specific examples of the TWS headset collecting the sound signal and converting the sound signal into the voice data may be: when a user uses the TWS headset to make a call, the microphone of one of the left ear plug 201-1 and the right ear plug 201-2 (e.g., the right ear plug 201-2) of the TWS headset is turned on. The right earpiece 201-2 may collect and convert the sound signal into voice data, which is then transmitted to the first electronic device 202 based on the bluetooth connection. When two users use the left earplug 201-1 and the right earplug 201-2 of the TWS headset to realize a call, the microphones of the left earplug 201-1 and the right earplug 201-2 of the TWS headset are both turned on. The left ear plug 201-1 and the right ear plug 201-2 of the TWS headset may collect and convert sound signals into voice data, respectively, and then transmit to the first electronic device 202 based on the bluetooth connection.

In some embodiments, the first electronic device 202 and the second electronic device 203 may be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) device, a Virtual Reality (VR) device, and the like, and the embodiments of the present application do not limit the specific form of the device. In addition, in the embodiment of the present application, the device forms of the first electronic device 202 and the second electronic device 203 may be the same, for example, the first electronic device 202 and the second electronic device 203 are both mobile phones. The device types of the first electronic device 202 and the second electronic device 203 may also be different, for example, the first electronic device 202 is a mobile phone, and the second electronic device 203 is a tablet computer. In the embodiment of the present application, the structures of the electronic devices (the first electronic device 202 and the second electronic device 203) may be as shown in fig. 5, which will be described in detail in the following embodiments.

Please refer to fig. 3, which is a schematic structural diagram of an earplug (a left earplug or a right earplug) of a TWS earphone according to an embodiment of the present application. As shown in fig. 3, the earplugs of the TWS headset may include: a processor 301, a memory 302, a sensor 303, a wireless communication module 304, at least one microphone 305, at least one microphone 306, and a power source 307.

The memory 302 may be used, among other things, for storing application code, such as for establishing a bluetooth connection with another earpiece of a TWS headset, and for enabling pairing of the earpiece with an electronic device, such as the first electronic device 202 described above. The processor 301 may control execution of the above-mentioned application program code to implement the functionality of the earpieces of the TWS headset in the embodiments of the present application.

The memory 302 may also have stored therein a bluetooth address for uniquely identifying the earpiece and a bluetooth address of another earpiece of the TWS headset. In addition, the memory 302 may also store connection data with an electronic device that the earplug has successfully paired before. For example, the connection data may be a bluetooth address of the electronic device that was successfully paired with the earpiece.

Wherein, the mobile phone 1 can communicate with the mobile phone 2. The left and right earplugs of the TWS headset may be used as a pair of binaural headphones to establish a bluetooth connection with the handset 1. Based on the established bluetooth connection, the mobile phone 1 and the TWS headset may transmit voice data during a call to implement a call function through the TWS headset.

When the TWS headset is used as a pair of binaural headsets, there are three connection modes of bluetooth connection between the TWS headset and the handset 1, which are respectively called as: a forwarding mode, a monitoring mode and a dual-transmission mode. In the repeating mode and the listening mode, one of the left and right earplugs may serve as a primary earpiece of the TWS headset, and the other earpiece may serve as a secondary earpiece of the TWS headset. For example, the left ear plug serves as a primary ear plug of the TWS headset and the right ear plug serves as a secondary ear plug of the TWS headset. As another example, the right earplug serves as a primary earplug for the TWS headset and the left earplug serves as a secondary earplug for the TWS headset. Also, the primary and secondary roles of the left and right earplugs of the TWS headset may be interchanged.

Wherein, in the forwarding mode, the main earplug of the TWS headset establishes a bluetooth connection with the handset 1. Based on this bluetooth connection, voice data transmission can be performed between the main earpiece and the handset 1. The main earplug and the auxiliary earplug establish a Bluetooth connection. Based on this bluetooth connection, the main earpiece may forward the voice data transmitted by the handset 1 to the secondary earpiece.

In the listening mode, the main earpiece of the TWS headset establishes a bluetooth connection with the handset 1. Based on this bluetooth connection, voice data transmission can be performed between the main earpiece and the handset 1. The secondary earpiece acquires voice data by listening to the link between the primary earpiece and the handset 1.

In the dual mode, the left and right earplugs of the TWS headset establish a bluetooth connection with the mobile phone 1, respectively. Based on the bluetooth connections established respectively, the left earplug and the right earplug can transmit voice data with the mobile phone 1.

For convenience of understanding, the method for performing a call by using a bluetooth headset according to the embodiment of the present application will be described in detail below with reference to the accompanying drawings and the difference between the connection modes of the bluetooth connection between the TWS headset and the mobile phone 1.

As shown in fig. 6, in the present embodiment, a connection mode of a bluetooth connection between a TWS headset and a mobile phone 1 is a forwarding mode, a user of the mobile phone 1 is referred to as a user 1, and a user of the mobile phone 2 is referred to as a user 2.

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

When the user 1 wishes to use the TWS headset for a call, the lid of the headset case of the TWS headset may be opened. The left earplug and the right earplug of the TWS earphone are automatically started or started after a function key is pressed. If the Bluetooth pairing is not completed before the left earplug and the right earplug, the left earplug and the right earplug can be automatically subjected to Bluetooth pairing, or the left earplug and the right earplug are subjected to Bluetooth pairing after the pairing function key is pressed down. If the bluetooth pairing has been completed before the left and right earplugs, the bluetooth pairing process may be omitted. After bluetooth pairing is completed, a control link 1 may be established between the left and right earplugs using bluetooth. Here, the control link 1 may be a first control link in this application.

Of the left and right earplugs of the TWS headset, the earpiece that is the primary earpiece (e.g., the right earpiece) establishes a control link 2 with the handset 1.

Wherein, any one of the left and right earplugs of the TWS earphone can be used as a main earplug. In some embodiments, the first of the left and right earplugs to be removed from the earphone case may be a primary earplug, and the other earplug may be a secondary earplug. Alternatively, the left and right earplugs include mating function keys, and the earplug whose mating function key is pressed first may serve as the primary earplug and the other earplug may serve as the secondary earplug. Alternatively, the one of the left and right earplugs that is first worn over the ear may be the primary earplug and the other earplug may be the secondary earplug. Or, which of the left and right earplugs is the main earplug and which of the left and right earplugs is the auxiliary earplug are predefined, for example, when the TWS headset leaves a factory, one of the left and right earplugs is configured as the main earplug, and the other one is configured as the auxiliary earplug. Wherein, the main earplug can be a first earplug in the application, and the auxiliary earplug can be a second earplug in the application.

Take the example of determining the primary and secondary earplugs according to the sequence of being worn on the ears. Illustratively, the right ear plug of the TWS headset is first worn by the user 1 onto the ear. For example, a proximity light sensor is included in the right earplug. When the right ear plug is worn on the ear, the right ear plug may detect an object near the right ear plug using the proximity light sensor, thereby determining that the right ear plug is worn by the user. Upon determining to be worn, the right earbud may transmit the paired broadcast out as a primary earbud pair of the TWS headset. If the handset 1 has bluetooth enabled, the handset 1 may receive the pairing broadcast and prompt the user that the associated bluetooth device (e.g., TWS headset) has been scanned. When the TWS headset is selected as a connected device on the handset 1, the handset 1 may be bluetooth paired with a right earpiece as the primary earpiece. After the bluetooth pairing is completed, the handset 1 can establish a control link 2 with the right earplug as the main earplug using bluetooth. Of course, if the right earpieces of the handset 1 and the TWS headset have previously completed bluetooth pairing, the bluetooth pairing process may be omitted. That is, the handset 1, upon receiving the pairing broadcast, may automatically establish the control link 2 with the right earpiece, which is the master earpiece, using bluetooth. Wherein, the control link 2 may be a second control link in the present application.

In the embodiment of the application, the control link 1 established between the left and right earpieces of the TWS headset and the control link 2 established between the right earpiece as the main earpiece and the handset 1 are used for transmitting control data (e.g. answering a call, hanging up a call, etc.). For realizing the transmission of voice data in the communication process, bluetooth is also needed to be adopted between the left and right earplugs of the TWS headset, and between the right earpiece serving as the main earpiece and the mobile phone 1 to establish voice links. In some embodiments, the voice link between the left and right earpieces (e.g., referred to as voice link 1, and voice link 1 may be the first voice link in this application) may be established after the primary and secondary earpieces acknowledge, or may be established when voice service (e.g., receiving an incoming call, receiving an operation to answer a call, or receiving an operation to make a call) is available. The voice link between the right earplug serving as the main earplug and the mobile phone 1 (for example, referred to as the voice link 2, the voice link 2 may be a second voice link in this application) may be established after the bluetooth pairing between the mobile phone 1 and the right earplug serving as the main earplug is completed, or may be established when there is voice service.

In some embodiments, the earpiece of the left and right earplugs of the TWS headset as the primary earpiece may also turn on the microphone of that earpiece for collection of sound signals. For example, the right earplug may also turn on the microphone of the right earplug after the right earplug is determined to be worn. The right earpiece acts as the primary earpiece of the TWS headset, while the left earpiece acts as the secondary earpiece of the TWS headset.

In addition, when the TWS headset is used as a pair of binaural headsets to realize a call, the left and right earpieces of the TWS headset are usually used by one user (such as the user 1), that is, only one user's voice signal needs to be collected. Therefore, only the microphone of the left and right earplugs of the TWS headset is opened as the earpiece of the main earpiece, and the microphone of the earpiece is not opened as the earpiece of the sub earpiece. For example, the microphone of the right ear plug as the main ear plug is opened, and the microphone of the left ear plug as the sub ear plug is not opened. In some embodiments, the right earplug, which is the primary earplug of the TWS headset, may be notified of the left earplug as a secondary earplug by the control link 1 described above. In this way, the left earpiece does not open the microphone of the left earpiece, even if the left earpiece is worn over the ear.

When a conference call is desired for a plurality of people, for example, when the user 3 wants to access a call through the mobile phone 1, one of the left and right earpieces of the TWS headset may be shared with the user 3. That is, user 1 and user 3 may talk using the left and right earpieces, respectively, in the TWS headset. In the process of a teleconference among multiple persons, the requirement of collecting the voice signal of the user 1 and the requirement of collecting the voice signal of the user 3 exist. Thus, not only the microphone of the earpiece of the TWS headset as the primary earpiece needs to be turned on, but also the microphone of the earpiece as the secondary earpiece. In the embodiment of the present application, the user may open the microphone of the earpiece serving as the secondary earpiece by performing the first operation, thereby achieving that the microphones of both the left and right earpieces of the TWS headset are in an on state.

For example, if the left ear plug as the secondary ear plug is not worn, the user 1 will typically share the left ear plug for use by the user 3. After the user performs the first operation, the left earpiece serving as the secondary earpiece may open the microphone of the left earpiece to achieve that the microphones of the left and right earpieces of the TWS headset are both in an on state.

For another example, if the left ear plug as the secondary ear plug is worn by the user 1, the user 1 may share the right or left ear plug of the TWS headset with the user 3.

If the user 1 wants to share the left earplug as the secondary earplug with the user 3 for use, after the user performs the first operation, the left earplug as the secondary earplug can open the microphone of the left earplug, so that the microphones of the left and right earplugs of the TWS headset are both in an open state.

If the user 1 wants to share the right earplug serving as the main earplug with the user 3, the user first takes the right earplug off the ear and then performs the first operation, then, when the user 1 takes the right earplug off the ear, the right earplug can detect that the right earplug is changed from being worn to being unworn, and at this time, the left earplug and the right earplug can exchange roles. After the primary and secondary roles are exchanged, the left earplug is used as a primary earplug of the TWS earphone, and the right earplug is used as a secondary earplug of the TWS earphone. And, the right earplug as the sub-earplug needs to turn off the microphone of the right earplug, and the left earplug as the main earplug needs to turn on the microphone of the left earplug. Then, after the user performs the first operation, the right earplug as the sub-earplug may open the microphone of the right earplug to achieve that the microphones of both the left and right earpieces of the TWS headset are in an on state.

If the user 1 wants to share the right earplug serving as the main earplug with the user 3 for use, the user performs the first operation first and then takes the right earplug off the ear, then after the user performs the first operation, the left earplug serving as the auxiliary earplug can open the microphone of the left earplug, so that the microphones of the left and right earplugs of the TWS headset are both in an open state. Then, when the user 1 takes the right earplug off the ear, the right earplug can detect that the right earplug is changed from being worn to not being worn, and at this time, the left and right earplugs can perform a primary-secondary role exchange. After the primary and secondary roles are exchanged, the left earplug is used as the primary earplug of the TWS earphone, and the right earplug is used as the secondary earplug of the TWS earphone. In some embodiments, the left and right earplugs may not be swapped for primary and secondary roles when the user 1 removes the right earpiece from the ear.

In some embodiments, when the right earplug, which is the master earplug, detects that the right earplug changes from being worn to not being worn, the specific process of the role exchange of the left and right earplugs may be: the right earplug, which is currently the primary earplug, transmits status information to the left earplug. The status information may include a bluetooth address (e.g., MAC address) of the TWS headset. This status information may be used to instruct the left earpiece to use the bluetooth address of the TWS headset instead of the right earpiece as the master earpiece and instead of the bluetooth connection (i.e. control link 2) between the right earpiece and the handset 1.

In addition, in the embodiment of the present application, if only the microphone of the earpiece, which is the main earpiece, of the left and right earpieces of the TWS headset is turned on, there is only a need for the main earpiece to transmit voice data to the sub-earpiece during a call. Thus, the voice link 1 described above may be a unidirectional voice link from the main ear plug to the secondary ear plug. However, if the microphones of the left and right earpieces of the TWS headset are both turned on, there is a need for the main earpiece to send voice data to the auxiliary earpiece, and also for the auxiliary earpiece to send voice data to the main earpiece during the communication. Thus, the above-mentioned voice link 1 may be a bi-directional voice link from the main earpiece to the secondary earpiece and vice-earbud to the main earpiece. In some embodiments, the bluetooth for establishing the voice link 1 between the left and right earpieces may specifically be: after the master and auxiliary earplugs confirm or voice service exists between the left and right earplugs or after Bluetooth pairing is completed, a two-way voice link is established by adopting Bluetooth. In some embodiments, the bi-directional voice link may be a synchronous connection-oriented/extended synchronous connection-SCO (SCO/eSCO) voice link of Bluetooth, and the voice link is configured as a bi-directional link. Or, after the confirmation of the main and auxiliary earpieces or when there is voice service between the left and right earpieces, a unidirectional voice link from the main earpiece to the auxiliary earpiece is established by using bluetooth first (for example, the unidirectional voice link may be an SCO/eSCO voice link of bluetooth, and the voice link is configured as a unidirectional link), and then, after receiving a first operation of the user, a unidirectional voice link from the auxiliary earpiece to the main earpiece is established by using bluetooth (for example, the unidirectional voice link may be a link established by using a Serial Port Profile (SPP)) so that a bidirectional voice link between the left and right earpieces is established. Or, after the confirmation of the main and auxiliary earpieces or when there is voice service between the left and right earpieces, a unidirectional voice link from the main earpiece to the auxiliary earpiece is established first by using bluetooth (for example, the unidirectional voice link may be an SCO/eSCO voice link of bluetooth, and the voice link is configured as a unidirectional link), and then, after receiving a first operation of the user, the unidirectional voice link established previously is removed, and then the bluetooth is used to establish a bidirectional voice link from the main earpiece to the auxiliary earpiece and from the auxiliary earpiece to the main earpiece (for example, the bidirectional voice link is an SCO/eSCO voice link of bluetooth, and the voice link is configured as a bidirectional link). It should be noted that, in the embodiment of the present application, the establishment process of the SCO/eSCO voice link may refer to the description of the corresponding content in the bluetooth standard protocol, and details are not described here again. As for the voice link 2, no matter the TWS headset opens the microphone of only one of the earpieces, or the microphones of both earpieces are open, during the call, there are both a requirement that the main earpiece transmits voice data to the mobile phone 1, and a requirement that the mobile phone 1 transmits voice data to the main earpiece, so the voice link 2 is a bidirectional voice link. That is, the handset 1 can send voice data to the main earpiece through the voice link 2, and the main earpiece can also send voice data to the handset 1 through the voice link 2.

In the embodiment of the present application, the implementation manner of the first operation may be various.

The first method is as follows: function keys, called conference mode function keys or other names, are configured on the earplugs or the earphone boxes of the TWS earphones, which is not limited in the embodiment of the present invention. The function keys are newly added keys on the earplug or the earphone box, or existing keys on the multiplexing earplug or the earphone box. The first operation is to trigger the function key, for example, pressing, or dialing, or touching, or knocking the function key. In the following, a conference mode function key is taken as an example, in this way, after the function key is triggered, the specific implementation that the auxiliary earplug opens the microphone of the auxiliary earplug can be as follows: for example, the conference mode function key is arranged on the earphone box of the TWS earphone, and the earphone box stores the main character and the auxiliary character information of the left and right earplugs. When the conference mode function key is activated, the earphone box of the TWS headset may send an indication to the primary earpiece instructing the secondary earpiece to turn on the microphone of the secondary earpiece. The master earpiece may send this indication to the secondary earpiece via the control link 1 described above. Alternatively, the earphone box may also send the indication to the sub-earplug. The secondary earplug may turn on the microphone of the secondary earplug in accordance with the received indication. It should be noted that the earphone box may send the indication to the main or auxiliary earphone via a wireless connection (e.g., bluetooth connection) with the main or auxiliary earphone. The earphone box may also send the indication to the auxiliary earplug via a wired connection with the auxiliary earplug when the auxiliary earplug is not removed from the earphone box. Also for example, a conference mode function key is arranged on an ear plug of the TWS headset. The secondary earpiece may turn on the microphone of the secondary earpiece when the conference mode function key of the secondary earpiece (where the conference mode function key of the secondary earpiece may be the first function key in this application) is triggered. Alternatively, when the conference mode function key of the main earpiece (wherein the conference mode function key of the main earpiece may be the second function key in this application) is triggered, the main earpiece may send an indication to the secondary earpiece via the above-mentioned control link 1. The secondary earpiece may turn on the microphone of the secondary earpiece in accordance with the received indication.

The second method comprises the following steps: the mobile phone 1 is configured with a function key of hardware, and the function key is called a conference mode function key or other name, which is not limited in the embodiment of the present invention. The function key of the hardware may be a third function key in the present application. The function key is a newly added key of the mobile phone 1, or an existing key (such as a volume key or a power key) on the mobile phone 1 is multiplexed. The first operation is to trigger the function key, for example, pressing, or dialing, or touching, or knocking the function key. In the following, a conference mode function key is taken as an example, in this way, after the function key is triggered, the specific implementation that the auxiliary earplug opens the microphone of the auxiliary earplug can be as follows: for example, when the conference mode function key is activated, the handset 1 may send an indication to the primary earpiece of the TWS headset over the control link 2 described above, the indication instructing the secondary earpiece to turn on the microphone of the secondary earpiece. The master earpiece may send this indication to the secondary earpiece via the control link 1 described above. The secondary earplug may turn on the microphone of the secondary earplug in accordance with the received indication.

The third method comprises the following steps: the mobile phone 1 may display a function control in the interface, where the function control is called a conference mode control, a multi-person mode control, or another name, and this is not limited in the embodiment of the present invention. The first operation is to trigger the function control, for example, clicking, double clicking, or pressing again. The following description will be made by taking a conference mode control as an example, and the conference mode control may be included in a notification bar of the mobile phone 1. The conference mode control may also be included in a call interface, an answering interface, or a setting interface displayed by the mobile phone 1. For example, the mobile phone 1 is a calling device, and the mobile phone 2 is a called device. The handset 1 can receive an operation of making a call. As shown in fig. 7, in response to the operation of making a call, the handset 1 may display a call interface 701, and a conference mode control 702 is included in the call interface 701. When the handset 1 receives a user trigger to the conference mode control 702, the handset 1 may turn on the microphone of the secondary earpiece in response to the trigger. In response to the operation of making a call, the handset 1 may also transmit a call request message to the handset 2. When the user of the mobile phone 2 selects 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 the call, the mobile phone 1 may display a call interface 801, where the call interface 801 includes a conference mode control 802. When the handset 1 receives a user trigger to the conference mode control 802, the handset 1 may turn on the microphone of the secondary earpiece in response to the trigger. For another example, the mobile phone 1 is a called device, and the mobile phone 2 is a calling device. When the handset 1 receives the call request message from the handset 2, as shown in fig. 9, the handset 1 can display an answering interface 901, where the answering interface 901 includes a conference mode control 902. When the handset 1 receives a user trigger to the conference mode control 902, the handset 1 may turn on the microphone of the secondary earpiece in response to the trigger. A listen button 903 may also be included in the listen interface 901. The mobile phone 1 can also receive a click operation of the answer button 903 by the user, 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 handset 1 opening the microphone of the secondary earpiece may be: for example, when the conference mode control (conference mode control 702, conference mode control 802, conference mode control 902, as described above) is triggered, the handset 1 may send an indication to the primary earpiece of the TWS headset over the control link 2, as described above, instructing the secondary earpiece to turn on the microphone of the secondary earpiece. The master earpiece may send this indication to the secondary earpiece via the control link 1 described above. The secondary earplug may turn on the microphone of the secondary earplug in accordance with the received indication.

Under the condition that the microphones of the left and right earplugs of the TWS earphone are both in an open state, the user 1 uses one earplug (such as a right earplug) of the TWS earphone, the user 3 uses the other earplug (such as a left earplug) of the TWS earphone and the user 2 using the mobile phone 2, and the three earplugs can be used for conversation, so that the three-person teleconference can be realized. In conjunction with fig. 6, the right earplug is taken as the main earplug of the TWS earphone, and the left earplug is taken as the auxiliary earplug of the TWS earphone.

In some embodiments, the handset 2 may capture the voice signal of the user 2 during the speech of the user 2. The mobile phone 2 converts the collected sound signal into voice data, such as voice data 2, and then sends the voice data to the mobile phone 1. The voice data 2 may be the second voice data in the present application.

After receiving the voice data 2 from the handset 2, the handset 1 may send the voice data 2 to the right earpiece, which is the primary earpiece of the TWS headset, via the voice link 2.

The left ear plug as the sub ear plug can collect a sound signal by the microphone of the left ear plug and convert it into voice data, such as called voice data 3. The left earpiece may send this voice data 3 to the right earpiece over the voice link 1 described above. It should be noted that if the user 3 has speech, the speech data 3 may be speech data obtained by processing a sound signal for the user 3. If the user 3 is not speaking, the speech data 3 may be silent data. The voice data 3 may be third voice data in the present application.

The right earplug can perform superposition processing (or called mixing processing) on the voice data 2 and the voice data 3 to realize mixing effect. For example, the voice data subjected to the superimposition is referred to as voice data 2-3. The right earpiece may play the voice data 2-3 through a receiver (i.e., earpiece) of the right earpiece.

The right ear plug may also collect a sound signal via the microphone of the right ear plug and convert it to voice data, such as referred to as voice data 1. If the user 1 has a speech, the speech data 1 may be speech data obtained by sound signal processing for the user 1. If the user 1 does not speak, the voice data 1 may be mute data. The voice data 1 may be the first voice data in the present application.

The right earplug can superpose the voice data 1 and the received voice data 2 to realize the sound mixing effect. For example, the superimposed voice data is referred to as voice data 1-2. The right earpiece may send this voice data 1-2 to the left earpiece over the voice link 1 described above. After the left earplug receives the voice data 1-2, the voice data 1-2 can be played through a receiver of the left earplug.

In addition, the right earplug can also perform superposition processing on the voice data 1 and the voice data 3 to realize a sound mixing effect. For example, the superimposed voice data is referred to as voice data 1 to 3. The right earpiece may send the voice data 1-3 to the handset 1 over the voice link 2 as described above. 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 right earplug, which is the primary earplug of the TWS headset, requires an overlay (or mixing) process for multi-path voice data. For example, the right earplug needs to perform superposition processing on the voice data 2 from the mobile phone 1 and the voice data 3 from the left earplug, perform superposition processing on the voice data 1 collected by the right earplug and the voice data 2 from the mobile phone 1, and perform superposition processing on the voice data 1 collected by the right earplug and the voice data 3 from the left earplug. In the embodiment of the application, a mixer can be added in the right earplug which is the main earplug of the TWS earphone for performing the superposition processing on the multi-path voice data. Of course, since it is possible for either the left or right ear piece of the TWS headset to serve as the primary ear piece, an audio mixer may be added to both the left and right ear pieces of the TWS headset. Alternatively, the superposition processing of multiple voice data may be implemented by a processor included in the ear piece of the TWS headset using a software algorithm.

In other embodiments, if the user 1 and the user 3 are relatively close to each other and can hear the voice of the other party, the right earplug as the main earplug may not perform the above-mentioned overlapping process of the voice data 2 and the voice data 3, but may play the voice data 2 from the mobile phone 1 through the receiver of the right earplug. The right earplug does not need to perform the superposition processing of the voice data 1 and the voice data 2, but only needs to send the voice data 2 to the left earplug for playing.

Therefore, the microphones of the left and right earplugs of the TWS earphone connected with one mobile phone are both opened and shared by two users, so that more than two persons can be conveniently communicated, namely, a multi-person teleconference can be realized. Moreover, the possibility that the environmental noise interferes with the call effect can be reduced.

As shown in fig. 10, in this embodiment, a connection mode of a bluetooth connection between a TWS headset and a mobile phone 1 is a listening mode, and a user of the mobile phone 1 is referred to as a user 1, and a user of the mobile phone 2 is referred to as a user 2.

The left and right earplugs of the TWS headset establish a control link 1. Of the left and right earplugs of the TWS headset, the earpiece that is the primary earpiece (e.g., the right earpiece) establishes a control link 2 with the handset 1. Here, the control link 1 may be a first control link in this application. Control link 2 may be the second control link in this application. The primary earplug may be a first earplug and the secondary earplug may be a second earplug.

In this embodiment, for specific descriptions of establishing the control link 1 between the left and right earplugs and establishing the control link 2 between the earpiece serving as the main earpiece and the mobile phone 1, reference may be made to the specific descriptions of corresponding contents in the embodiment shown in fig. 6, which are not described in detail herein again.

For the voice link for transmitting voice data during a call, see, for example, voice link 1 and voice link 2 shown in fig. 10. The specific description of the voice link 2 may refer to the specific description of the corresponding contents 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 detailed description of the voice link 1 is similar to that of the corresponding content in the embodiment shown in fig. 6, with the difference that:

the difference is that in the forwarding mode, the auxiliary earplug obtains the voice data from the mobile phone 1 through the forwarding of the main earplug. In the listening mode, the secondary earpiece acquires the voice data from the mobile phone 1 by listening to the voice link (e.g., the voice link 2) between the primary earpiece and the mobile phone 1. Therefore, unlike the voice link 1 in the embodiment shown in fig. 6, in the present embodiment, the voice link 1 is used for transmitting the voice data processed by the sound signal collected by the right ear plug and the voice data processed by the sound signal collected by the left ear plug. Wherein, the voice link 1 only has voice data transmission under the condition that the microphones of the left and right earplugs of the TWS earphone are both opened.

In the embodiment, the voice link 1 can be established not only after the primary and secondary earplugs are confirmed, but also when there is voice service, or after the bluetooth pairing of the left and right earplugs is completed, or after the first operation is received.

In the third difference, since the voice link 1 is used for transmitting 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, in the present embodiment, once the voice link 1 is to be established, a bidirectional voice link needs to be established.

In addition, in the present embodiment, after the right earplug as the main earplug establishes the voice link 2 with the mobile phone 1, the right earplug can also send the connection parameters of the voice link 2 to the left earplug as the auxiliary earplug through the control link 1. For example, the connection parameters may include a bluetooth address of the mobile phone 1, codec parameters, clock parameters, encryption parameters negotiated by the mobile phone 1 and the master earpiece, and the like. The left earplug can monitor the voice link 2 between the main earplug and the mobile phone 1 according to the link parameter, so as to obtain the voice data sent by the mobile phone 1.

In some embodiments, the earpiece of the left and right earplugs of the TWS headset as the primary earpiece may also turn on the microphone of that earpiece for collection of the user's (e.g., user 1) sound signals. When a conference call is desired for a plurality of people, for example, when the user 3 wants to access a call through the mobile phone 1, one of the left and right earpieces of the TWS headset may be shared with the user 3. That is, user 1 and user 3 may talk using the left and right earpieces, respectively, in the TWS headset. In the process of a teleconference among multiple persons, the requirement of collecting the voice signal of the user 1 and the requirement of collecting the voice signal of the user 3 exist. Thus, not only the microphone of the earpiece of the TWS headset as the primary earpiece needs to be turned on, but also the microphone of the earpiece as the secondary earpiece. In the embodiment of the present application, the user may open the microphone of the earpiece serving as the secondary earpiece by performing the first operation, thereby achieving that the microphones of both the left and right earpieces of the TWS headset are in an on state.

In this embodiment, for specific descriptions of the microphones of the left and right earpieces of the TWS headset being in the on state and the implementation of the first operation, reference may be made to the specific descriptions of corresponding contents in the embodiment shown in fig. 6, and details of this embodiment are not described herein again.

Under the condition that the microphones of the left and right earplugs of the TWS earphone are both in an open state, the user 1 uses one earplug (such as a right earplug) of the TWS earphone, the user 3 uses the other earplug (such as a left earplug) of the TWS earphone and the user 2 using the mobile phone 2, and the three earplugs can be used for conversation, so that the three-person teleconference can be realized. In conjunction with fig. 10, the right earplug is taken as the main earplug of the TWS earphone, and the left earplug is taken as the auxiliary earplug of the TWS earphone.

In some embodiments, the handset 2 may capture the voice signal of the user 2 during the speech of the user 2. The mobile phone 2 converts the collected sound signal into voice data, such as voice data 2, and then sends the voice data to the mobile phone 1.

After receiving the voice data 2 from the handset 2, the handset 1 may send the voice data 2 to the right earpiece, which is the primary earpiece of the TWS headset, via the voice link 2. The voice data 2 may be the second voice data in the present application.

The right ear plug may also collect a sound signal via the microphone of the right ear plug and convert it to voice data, such as referred to as voice data 1. If the user 1 has a speech, the speech data 1 may be speech data obtained by sound signal processing for the user 1. If the user 1 does not speak, the voice data 1 may be mute data. The right earpiece may send this voice data 1 to the left earpiece over the voice link 1 described above. The voice data 1 may be the first voice data in the present application.

The left ear plug can also listen to the voice link 2 between the handset 1 and the right ear plug to obtain voice data 2.

The left ear plug can perform superposition processing on the voice data 1 and the voice data 2 to realize the sound mixing effect. The voice data after being superimposed, for example, is referred to as voice data 1-2. The left earpiece can play the voice data 1-2 through the receiver of the left earpiece.

It can be seen that the right earplug, which is the main earplug of the TWS headset, and the left earplug, which is the sub-earplug, need to be subjected to an overlap (or mixing) process on multiple voice data. For example, the right earplug needs to perform superposition processing on the voice data 2 from the mobile phone 1 and the voice data 3 from the left earplug, and performs superposition processing on the voice data 1 collected by the right earplug and the voice data 3 from the left earplug. The left ear plug needs to perform an overlay process of the voice data 1 from the right ear plug and the monitored voice data 2. In the embodiment of the present application, a mixer may be added to the left and right earpieces of the TWS headset, or a processor included in the earpieces of the TWS headset may also use a software algorithm to implement the superposition processing of multiple paths of voice data.

In other embodiments, if the user 1 and the user 3 are relatively close to each other and can hear the voice of the other party, the right earplug as the main earplug may not perform the above-mentioned overlapping process of the voice data 2 and the voice data 3, but may play the voice data 2 from the mobile phone 1 through the receiver of the right earplug. The right earplug does not need to transmit the voice data 1 to the left earplug, and the left earplug does not need to perform the superposition processing of the voice data 1 and the voice data 2, but only needs to play and monitor the voice data 2 obtained by the voice link 2. The voice link 1 may not be a bidirectional voice link, but a unidirectional voice link from a left earplug as a secondary earplug to a right earplug as a primary earplug, and is used for transmitting the left earplug and the right earplug to transmit the voice data 3, so that the right earplug performs mixing processing on the voice data 3 and the collected voice data 1 and sends the mixed voice data to the mobile phone 1.

As shown in fig. 11, in the present embodiment, the connection mode of the bluetooth connection between the TWS headset and the mobile phone 1 is a dual mode, the user of the mobile phone 1 is referred to as the user 1, and the user of the mobile phone 2 is referred to as the user 2.

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

In this embodiment, for the specific description of establishing the control link 1 between the left and right earplugs, reference may be made to the specific description of corresponding contents in the embodiment shown in fig. 6, which is not described in detail here. Wherein the left earplug can be a first earplug in the application, and the right earplug can be a second earplug in the application; alternatively, the left earplug may be the second earplug and the right earplug may be the first earplug. Control link 1 may be the first control link in this application.

The left and right earplugs of the TWS headset establish control links with the handset 1, respectively.

For example, as shown in fig. 11, the right ear plug establishes a control link 2 with the handset 1 and the left ear plug establishes a control link 3 with the handset 1. Control link 2 may be the second control link in this application. The control link 3 may be a third control link in the present application. In some embodiments, the specific process for the left and right earplugs of the TWS headset to establish the control link with the handset 1 respectively may be: either one of the left and right earpieces (e.g., the right earpiece) of the TWS headset may transmit the paired broadcast to the outside. If the handset 1 has bluetooth enabled, the handset 1 may receive the pairing broadcast and prompt the user that the associated bluetooth device (e.g., TWS headset) has been scanned. When the TWS headset is selected as a connected device on the handset 1, the handset 1 may be bluetooth paired with the right earpiece of the TWS headset. After the right earplug is Bluetooth paired with the mobile phone 1, the right earplug and the mobile phone 1 can establish a control link 2 by adopting Bluetooth. Of course, if the handset 1 has previously completed bluetooth pairing with the right ear plug of the TWS headset, the bluetooth pairing process may be omitted. That is, the mobile phone 1 can automatically establish the control link 2 with the right earplug using bluetooth after receiving the pairing broadcast. The right earpiece may send the bluetooth address of the handset 1 to the left earpiece so that the left earpiece establishes a control link with the handset 1. For example, the right earplug may transmit the bluetooth address of the handset 1 to the left earplug via the control link 1 and inform the left earplug to transmit the paired broadcast to the outside. In this way, the handset 1 can receive the pairing broadcast sent by the left earpiece and perform bluetooth pairing with the left earpiece. After the left earplug and the mobile phone 1 are bluetooth paired, the left earplug and the mobile phone 1 can establish a control link 3 by using bluetooth. Of course, if the handset 1 and the left earpiece of the TWS headset have previously completed bluetooth pairing, the bluetooth pairing process may be omitted. That is, the mobile phone 1 can automatically establish the control link 3 with the left earphone by bluetooth after receiving the pairing broadcast.

It should be noted that the above process of establishing control links between the left and right earplugs of the TWS headset and the handset 1 is only an example. In some embodiments, the mobile phone 1 may also perform bluetooth pairing with the left earpiece of the TWS headset and establish the control link, and then the left earpiece transmits the bluetooth address of the mobile phone to the right earpiece and notifies the right earpiece to transmit pairing broadcast to the outside, so that the right earpiece performs bluetooth pairing with the mobile phone 1 and establishes the control link. In some other embodiments, the left earplug and the right earplug of the TWS headset may respectively send pairing broadcasts to the outside after being powered on, so that the left earplug and the right earplug can respectively perform bluetooth pairing with the mobile phone 1 and respectively establish a control link with the mobile phone 1. In addition, in the embodiment of the application, the triggering condition for the left earplug or the right earplug of the TWS headset to send the paired broadcast to the outside may be that the box cover of the headset box of the TWS headset is opened, or that the bluetooth pairing of the left earplug and the right earplug of the TWS headset is completed, or that the pairing function key is pressed. Wherein, the pairing function key can be arranged on an earphone box of the TWS earphone. For example, the earphone box of the TWS earphone is provided with a pairing function key, when the pairing function key is pressed, the left earphone or the right earphone of the TWS earphone can send the pairing broadcast to the outside. Pairing function keys may also be provided on the left and right earpieces of the TWS headset. For example, a left earpiece and/or a right earpiece of a TWS headset is configured with a pairing function key, when the pairing function key is pressed, the corresponding earpiece transmits a pairing broadcast to the outside.

In some embodiments, since the TWS headset is used as a pair of binaural headphones for conversation, the left and right earpieces of the TWS headset are typically intended for one user (e.g., user 1), i.e., only one user's voice signal needs to be picked up. Thus, the earpiece of either of the left or right earpieces of a TWS headset may also turn on the microphone of that earpiece for the collection of sound signals of a user (e.g., user 1). For example, in some embodiments, the earpiece of the left and right earplugs that was first removed from the headset case may have its microphone turned on, and the microphone of the other earpiece may not be turned on. Or, the earphone which is firstly paired with the mobile phone in the left and right earphones opens the microphone of the earphone, and the microphone of the other earphone can not be opened. Alternatively, the left and right earplugs include mating function keys, and the earpiece whose mating function key is pressed first may have its microphone turned on, and the microphone of the other earpiece may not be turned on. Alternatively, the one of the left and right earplugs that is first worn over the ear may have its microphone turned on, and the microphone of the other earpiece may not be turned on.

Take the example of determining which earplug opens the microphone and which does not open the microphone according to the sequence of pairing with the mobile phone bluetooth. For example, the right earplug is first bluetooth paired with the mobile phone 1, and then the right earplug may open the microphone of the right earplug, and the left earplug may not open the microphone of the left earplug. In some embodiments, the right earplug may inform the left earplug via control link 1 described above that the right earplug has the microphone turned on. In this way, the left earpiece does not open the microphone of the left earpiece, even if the left earpiece is worn over the ear.

When a conference call is desired for a plurality of people, for example, when the user 3 wants to access a call through the mobile phone 1, one of the left and right earpieces of the TWS headset may be shared with the user 3. That is, user 1 and user 3 may talk using the left and right earpieces, respectively, in the TWS headset. In the process of a teleconference among multiple persons, the requirement of collecting the voice signal of the user 1 and the requirement of collecting the voice signal of the user 3 exist. Thus, not only the microphone of one of the earpieces (e.g. the right earpiece) of the TWS headset needs to be turned on, but also the microphone of the other earpiece (e.g. the left earpiece). In the embodiment of the present application, the user can open the microphone of the other earpiece by performing the first operation, so that the microphones of the left and right earpieces of the TWS headset are both in the on state.

For example, in some embodiments, an ear bud with a microphone open may be defined as a primary ear bud, and an ear bud without a microphone open may be defined as a secondary ear bud. Correspondingly, for specific descriptions of the microphones of the left and right earpieces of the TWS headset being in the on state and the implementation of the first operation, reference may be made to the specific descriptions of corresponding contents in the embodiment shown in fig. 6, which is not described in detail herein. In other embodiments, the handset 1 may also record which of the left and right earpieces of the TWS headset has its microphone on and the microphone of that earpiece is not. After the user performs the first operation, the handset 1 may send an instruction to the earpiece without the microphone open through the control link with the earpiece, so as to instruct the earpiece to open the microphone.

For the voice link for transmitting 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. The voice link 3 may be a third voice link in the present application. The specific description of the voice link 2 may refer to the specific description of the corresponding contents in the embodiment shown in fig. 6. The detailed description of the voice link 1 is similar to that of the corresponding content in the embodiment shown in fig. 6, with the difference that:

the difference is that in the forwarding mode, the auxiliary earplug obtains the voice data from the mobile phone 1 through the forwarding of the main earplug. In the dual mode, the handset 1 can transmit voice data to the left ear plug and the right ear plug, respectively. Therefore, unlike the voice link 1 in the embodiment shown in fig. 6, in the present embodiment, the voice link 1 is used for transmitting the voice data processed by the sound signal collected by the right ear plug and the voice data processed by the sound signal collected by the left ear plug. Wherein, the voice link 1 only has voice data transmission under the condition that the microphones of the left and right earplugs of the TWS earphone are both opened.

In the embodiment, the voice link 1 may be established when there is voice service, may be established after the bluetooth pairing of the left and right earpieces is completed, and may also be established after the first operation is received.

The voice link 1 may be not only a bluetooth SCO/eSCO voice link but also a connection-based isochronous audio stream (CIS) link based on an Isochronous (ISO) channel (channel). In the embodiment of the present application, the process of establishing the CIS link based on the ISO channel may refer to the description of corresponding content in the standard protocol related to the ISO channel, and details are not described herein again.

In addition, in this embodiment, not only the right ear plug of the TWS headset is to establish a voice link with the handset 1, such as the voice link 2 described above, but also the left ear plug is to establish a voice link with the handset 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.

With reference to fig. 11, when the microphones of the left and right earpieces of the TWS headset are both in the on state, the user 1 can use one earpiece (e.g., the right earpiece) of the TWS headset, the user 3 can use the other earpiece (e.g., the left earpiece) of the TWS headset and the user 2 using the mobile phone 2, and the three can have a conversation, i.e., a three-person teleconference can be achieved.

After receiving the voice data 2 from the handset 2, the handset 1 may send the voice data 2 to the right earpiece of the TWS headset via the voice link 2. The handset 1 may also send this voice data 2 to the left earpiece of the TWS headset over the voice link 3 described above. The voice data 2 may be the second voice data in the present application.

The left earpiece may collect the sound signal through the microphone of the left earpiece and convert it to voice data, referred to as voice data 3. The left earpiece may send this voice data 3 to the right earpiece over the voice link 1 described above. The left earpiece may also send this voice data 3 to the handset 1 via the voice link 3 as described above. It should be noted that if the user 3 has speech, the speech data 3 may be speech data obtained by processing a sound signal for the user 3. If the user 3 is not speaking, the speech data 3 may be silent data. The voice data 3 may be third voice data in the present application.

The right ear plug may also collect a sound signal via the microphone of the right ear plug and convert it to voice data, such as referred to as voice data 1. If the user 1 has a speech, the speech data 1 may be speech data obtained by sound signal processing for the user 1. If the user 1 does not speak, the voice data 1 may be mute data. The right earpiece may send this voice data 1 to the left earpiece over the voice link 1 described above. The right ear plug may also transmit the voice data 1 to the handset 1 via the voice link 2 as described above. The voice data 1 may be the first voice data in the present application.

In addition, the mobile phone 1 can also perform superposition processing on the voice data 1 and the voice data 3 to achieve a sound mixing effect. For example, the superimposed voice data is referred to as voice data 1 to 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 right earplug, the left earplug and the mobile phone 1 need to perform superposition (or mixing) processing on multiple voice data. For example, the right ear plug needs to perform an overlay process of the voice data 2 from the handset 1 and the voice data 3 from the left ear plug. The left earpiece needs to overlap the voice data 1 from the right earpiece and the voice data 2 from the handset 1. The handset 1 needs to perform an overlay process of the voice data 1 from the right ear plug and the voice data 3 from the left ear plug. In the embodiment of the present application, a mixer may be added to the left and right earpieces of the TWS headset, or a processor included in the earpieces of the TWS headset may also use a software algorithm to implement the superposition processing of multiple paths of voice data. A mixer may be added to the mobile phone 1, or a processor of the mobile phone 1 may also use a software algorithm to implement superposition processing of multiple paths of voice data.

In other embodiments, if the user 1 and the user 3 are relatively close to each other and can hear the voice of the other party, the left and right earplugs may not perform the above-mentioned voice data superposition process, but play the voice data 2 from the mobile phone 1 through the receiver. In this way, no voice link, i.e. the above-mentioned voice link 1, can be established between the left and right earplugs.

In addition, in the embodiments shown in fig. 6, 10 and 11, the handset 2 may also be connected to a TWS headset for use by two users, so that a four-person teleconference may be achieved. It should be noted that the connection mode of the bluetooth connection between the mobile phone 2 and the TWS headset may be any one of the forwarding mode, the listening mode, and the dual mode. The connection mode of the bluetooth connection between the mobile phone 1 and the TWS headset may be the same as or different from the connection mode of the bluetooth connection between the mobile phone 2 and the TWS headset. For specific implementation of the TWS headset as the audio input/output device of the mobile phone 2 to implement a call, reference may be made to specific description of corresponding content in the call implemented by the TWS headset as the audio input/output device of the mobile phone 1 in the foregoing embodiment, and details are not repeated here.
