For convenience of understanding, the process of establishing a service connection between the terminal and the bluetooth headset is described below by taking the terminal as a mobile phone as an example. The process of establishing the service connection between the terminal and the Bluetooth headset comprises three stages, namely a scanning stage, a pairing stage and a service connection establishing stage. The following is a detailed description with reference to fig. 3A to 3E.

Fig. 3A to fig. 3E are schematic diagrams of a terminal interface in an application scenario provided in the embodiment of the present application. Illustratively, as shown in fig. 3A, selecting "bluetooth" in the terminal setting interface enters a bluetooth setting interface, which is shown in fig. 3B. Referring to fig. 3B, when the terminal receives an instruction corresponding to the bluetooth activation option operated by the user, the terminal activates the bluetooth function. In some scenarios, after the terminal turns on the bluetooth function, it can discover nearby paired bluetooth devices and display the scanned bluetooth devices in an "available devices" list. Exemplarily, fig. 3B illustrates a case where the current terminal device HUAWEIP30 scans the bluetooth device HUAWEIMate20 and the bluetooth headset 1. This phase is called the scan phase.

In some scenarios, when the terminal detects that the user clicks a bluetooth device in the "available device" list, the terminal will pair with the bluetooth device. For example, as shown in fig. 3C, when the terminal detects that the user clicks "bluetooth headset 1" in the "available device" list, the terminal pairs with the bluetooth headset 1, and if the pairing is successful, the "bluetooth headset 1" is displayed in the "paired device" list, as shown in fig. 3D. This phase is called the pairing phase.

In some scenarios, if the terminal has previously established a service connection with some other bluetooth device, the bluetooth device that has established the service connection may be displayed in the "paired device" list. Referring to fig. 3D, the list of "paired devices" also shows the bluetooth devices, huabei free bugs, which have established traffic connections.

In some scenarios, when the terminal detects that the user clicks a certain bluetooth device in the "paired device" list, the terminal establishes a service connection with the bluetooth device. As shown in fig. 3E, when the terminal detects that the user clicks "bluetooth headset 1" in the "device that can be paired" list, the terminal establishes service connection with the bluetooth headset 1. If the service connection is successfully established, audio data can be transmitted between the terminal and the bluetooth headset 1. This phase is called the traffic connection setup phase. The interaction process between the terminal and the bluetooth headset described in the following embodiments is performed after the terminal and the bluetooth headset establish a service connection.

It should be noted that the schematic diagrams of the terminal interfaces illustrated in fig. 3A to 3E are only an example. The setting interfaces and operation modes corresponding to different terminal devices may be different.

After the terminal is connected with the Bluetooth headset, audio data can be transmitted between the terminal and the Bluetooth headset. For the TWS Bluetooth headset, when the terminal is connected with the Bluetooth headset, the terminal is only connected with the main headset in a Bluetooth mode, and the terminal is not required to be connected with the auxiliary headset in a Bluetooth mode. And the main earphone and the auxiliary earphone are communicated in a data forwarding mode. Illustratively, the terminal sends the audio data to the main earphone, and the main earphone forwards the audio data to the auxiliary earphone after receiving the audio data, so as to realize synchronous sound production between the main earphone and the auxiliary earphone.

The bluetooth physical link between the terminal and the TWS bluetooth headset is divided into two types, one is an Asynchronous Connection Less (ACL) link, and the other is a Synchronous Connection Oriented (SCO) link.

ACL links are basic connections for bluetooth and are typically used to transmit connection-type negotiation signaling for maintaining a bluetooth connection. ACL links also support unidirectional transmission of audio data. Illustratively, when the terminal sends audio data to the master earpiece over the ACL link, the master earpiece cannot send audio data to the terminal at the same time.

The SCO link is a connection technology supported by the bluetooth baseband, and uses reserved time slots to transmit data. The SCO link supports bi-directional transfer of audio data. Illustratively, when the terminal sends audio data to the master earphone over the SCO link, the master earphone may also send audio data to the terminal over the SCO link.

Current TWS bluetooth headsets typically have the basic functions of listening to music and making and receiving calls. The following describes a communication process between the terminal and the bluetooth headset in combination with two application scenarios of music listening and telephone dialing.

Fig. 4A is a schematic diagram of a link between a terminal and a bluetooth headset in a music listening scene according to an embodiment of the present application. As shown in fig. 4A, in a music listening scenario, the terminal establishes an ACL link with a primary one of the TWS bluetooth headsets, and an ACL link is also established between the primary and secondary headsets.

Fig. 4B is a schematic diagram of data transmission between a terminal and a bluetooth headset in a music listening scene according to an embodiment of the present application. As shown in fig. 4B, the terminal receives music to be played selected by the user. When the terminal plays the music, the currently played audio data is sent to the main earphone through the ACL link, and the main earphone forwards the received audio data to the auxiliary earphone through the ACL link. The Bluetooth headset controls the main headset and the auxiliary headset to synchronously play the audio data, so that the user can listen to music through the main headset and/or the auxiliary headset.

In practical application, the wearing states of the main earphone and the auxiliary earphone can be detected, and audio data can be transmitted according to the wearing states of the main earphone and the auxiliary earphone. Illustratively, when detecting that the user wears the main earphone and the auxiliary earphone at the same time, the terminal sends the currently played audio data to the main earphone through the ACL link, and the main earphone forwards the received audio data to the auxiliary earphone through the ACL link, so that the main earphone and the auxiliary earphone synchronously sound. When detecting that the user only wears the main earphone, the terminal sends the currently played audio data to the main earphone through the ACL link, and the main earphone does not need to forward the audio data to the auxiliary earphone. When detecting that the user only wears the auxiliary earphone, the roles of the main earphone and the auxiliary earphone can be switched, namely the main earphone is switched into the auxiliary earphone, and the auxiliary earphone is switched into the main earphone. Then, the terminal sends the currently played audio data to the main earphone through the ACL link, and the main earphone does not need to forward the audio data to the auxiliary earphone.

The wearing states of the main earphone and the auxiliary earphone can be detected in various detection modes. For example, a sensor-based wearing detection technique may be adopted, that is, sensors are provided in the primary and secondary earphones, and the sensors are used for acquiring wearing state signals. Whether the main earphone or the auxiliary earphone is in a wearing state can be determined according to the wearing state signals collected by the optical proximity sensor. The sensor may be one or more of an optical proximity sensor, a pressure sensor, a heat sensor, and a moisture sensor.

Fig. 5A is a schematic diagram of a link between a terminal and a bluetooth headset in a call dialing scenario according to an embodiment of the present application. As shown in fig. 5, in a dial-up scenario, the terminal establishes an SCO link with a primary earpiece of the TWS bluetooth headset, and an SCO link is also established between the primary and secondary earpieces.

Fig. 5B is a schematic diagram of data transmission between a terminal and a bluetooth headset in a call dialing scenario according to an embodiment of the present application. As shown in fig. 5B, the user wears the primary and secondary earphones at the same time. When a user carries out voice communication, the microphone of the main earphone carries out voice collection, and the microphone of the auxiliary earphone does not carry out voice collection. The microphone of the main earphone collects first voice data spoken by a user, the collected first voice data is sent to the terminal through the SCO link, and the terminal performs voice processing and transmits the voice data to the other party through a wireless transmission technology. Meanwhile, after receiving second voice data of the other party of the call, the terminal sends the second voice data to the main earphone through the SCO link, and the main earphone forwards the received second voice data to the auxiliary earphone through the SCO link. The Bluetooth headset controls the main headset and the auxiliary headset to synchronously play the second voice data, so that the user can listen to the second voice data of the other party through the main headset and the auxiliary headset.

In the present application, the master earphone refers to an earphone that establishes a connection link with the terminal, and is not limited to the left earphone or the right earphone. In some scenarios, the primary earpiece is the left earpiece and the secondary earpiece is the right earpiece. In other scenes, the main earphone is a right earphone and the auxiliary earphone is a left earphone. In still other scenarios, the primary and secondary earpieces may also be switched. In one possible mode, the switching can be performed according to the electric quantity states of the main earphone and the auxiliary earphone. For example, if the power of the current primary earphone is lower than a certain threshold and the power of the primary earphone is lower than the power of the secondary earphone, the secondary earphone is switched to the primary earphone. In another possible mode, the switching can be carried out according to the wearing states of the main earphone and the auxiliary earphone. For example, in some application scenarios, if the bluetooth headset detects that the primary headset is out of the ear or falls, the primary headset is switched to the secondary headset, and the secondary headset is switched to the primary headset.

The current TWS Bluetooth headset usually only has the basic functions of listening music and receiving and making calls, so that the function of the Bluetooth headset is single. In order to enrich the application scenes of the TWS Bluetooth headset and meet the multifunctional requirements of a user on the TWS Bluetooth headset, the embodiment of the application provides a Bluetooth communication method.

In the application, the microphones of the main earphone and the auxiliary earphone of the TWS Bluetooth earphone respectively collect voice data of different users, and the TWS Bluetooth earphone and the terminal are utilized to realize the function of simultaneous interpretation. Illustratively, a user a speaking a first language wears a primary earpiece and a user B speaking a second language wears a secondary earpiece. When the user A and the user B have a conversation, the microphone of the main earphone collects voice data of the first language spoken by the user A and sends the voice data to the terminal, and the terminal translates the voice data into the second language and then transmits the second language to the auxiliary earphone. And the microphone of the auxiliary earphone collects the voice data of the second language spoken by the user B and sends the voice data to the terminal, and the terminal translates the voice data into the first language and then transmits the first language to the main earphone. Thus, an unobstructed conversation between user a and user B is achieved.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.

Fig. 6 is a flowchart illustrating a bluetooth communication method according to an embodiment of the present application. As shown in fig. 6, the method includes:

s601: and a first ACL link is established between the terminal and the main earphone, and a second ACL link is established between the main earphone and the auxiliary earphone.

S602: and the terminal sends first audio data to the main earphone through the first ACL link, and the main earphone forwards the first audio data to the auxiliary earphone through the second ACL link.

In this embodiment, in S601 and S602, the TWS bluetooth headset is in a music listening scene. Illustratively, the schematic diagram of the links between the terminal, the main headset and the sub-headset is shown in fig. 4A, that is, ACL links are established between the terminal and the main headset and between the main headset and the sub-headset. For convenience of description, in the present embodiment, an ACL link between the terminal and the main headset is referred to as a first ACL link, and an ACL link between the main headset and the sub-headset is referred to as a second ACL link.

The audio transmission process between the terminal, the main earphone and the sub-earphone is shown in fig. 4B. Namely, the terminal sends the first audio data to the main earphone through the first ACL link, and the main earphone forwards the received first audio data to the auxiliary earphone through the ACL link. Wherein, the first audio data is media audio data, including but not limited to: music, audio data in a movie program, audio data of a recording, etc.

S603: the terminal receives a first scene change instruction.

Wherein the first scene change instruction is used for indicating that the application scene of the TWS Bluetooth headset is changed. In this application, the application scenarios of the bluetooth headset include but are not limited to: listening to music scenes, calling scenes, simultaneous interpretation scenes and double-person conversation scenes. Fig. 4A shows a link between the terminal and the bluetooth headset in a music listening scene, and fig. 4B shows a transmission process of audio data. The link between the terminal and the bluetooth headset in the call-making scenario is shown in fig. 5A, and the transmission process of the audio data is shown in fig. 5B.

In different application scenes, the wearing mode and the working mode of the Bluetooth headset are different. The wearing mode and the working mode in several application scenarios are respectively described below.

In the scene of listening music and making a call, the corresponding wearers of the main earphone and the auxiliary earphone are the same. In a music listening scene, the main earphone and the auxiliary earphone only play audio, and the audio data played by the main earphone and the auxiliary earphone are the same. And the microphones of the main earphone and the auxiliary earphone are not used for audio acquisition.

In a calling scene, the main earphone can perform audio playing and audio acquisition, and the auxiliary earphone only performs audio playing and does not perform audio acquisition. Also, in the call placement scenario, the audio data played by the primary and secondary earpieces is the same.

In the simultaneous interpretation scenario, the primary and secondary earpieces correspond to different wearers. The main earphone and the auxiliary earphone can simultaneously play audio and collect audio, and the audio data played by the main earphone and the auxiliary earphone is different, and the audio data collected by the main earphone and the auxiliary earphone is different.

In a double-person conversation scene, the corresponding wearers of the main earphone and the auxiliary earphone are different. The main earphone and the auxiliary earphone can simultaneously play audio and collect audio, the audio data collected by the main earphone and the auxiliary earphone are different, and the audio data played by the main earphone and the auxiliary earphone are the same.

In the embodiment of the application, the terminal receives the first scene change instruction, and the first scene change instruction may be directly input to the terminal by the user, or may be input to the TWS bluetooth headset by the user and forwarded to the terminal by the TWS bluetooth headset.

In some embodiments, the TWS bluetooth headset receives a first operation input by a user to the TWS bluetooth headset, and in response to the first operation, the TWS bluetooth headset transmits a first scene change instruction to the terminal. For example, when the user needs to change the application scene of the bluetooth headset, the first operation may be input to the bluetooth headset. The user may input the first operation to the bluetooth headset in various ways. In one possible embodiment, a mode switching button is provided on the body of the bluetooth headset, and the user can operate the mode switching button, for example, the user can click the mode switching button, or double click the mode switching button, or touch the mode switching button to input the first operation to the bluetooth headset. In another possible implementation, the bluetooth headset may recognize a preset voice command, and the user may input the preset voice command to the bluetooth headset to implement scene change. For example, when a user needs to apply the bluetooth headset to a music listening scene, the user may input a voice "enter a music listening mode" to the bluetooth headset. When a user needs to apply the Bluetooth headset to a simultaneous interpretation scene, the user can input voice to the Bluetooth headset to enter a simultaneous interpretation mode.

In other embodiments, the terminal receives a first scene change instruction input by a user. Illustratively, the user may input the first scene change instruction to the terminal in various ways, similar to the way the user inputs the first scene change instruction to the TWS bluetooth headset. For example: in a terminal interface, a first scene change instruction is input to a terminal in a mode of clicking a mode switching control, double-clicking the mode switching control, touching the mode switching control, sliding the mode switching control and the like. The first scene change instruction may also be input to the terminal by means of voice interaction, for example, inputting a voice "enter simultaneous interpretation mode" to the terminal.

In some embodiments, sensors are disposed in the primary earphone and the secondary earphone for collecting wearing status signals of the primary earphone and the secondary earphone. The sensor may be one or more of an optical proximity sensor, a pressure sensor, a thermal sensor, a moisture sensor. Whether the current application scene is switched or not can be intelligently determined according to the wearing state signal acquired by the sensor of the main earphone and the wearing state signal acquired by the sensor of the auxiliary earphone. For example, the sensor is taken as a thermal sensor, and the wearing state signal acquired by the thermal sensor indicates the body temperature of the wearer. In a music listening scene or a call making scene, the wearing state signals corresponding to the main earphone and the auxiliary earphone are possibly the same or similar, and the difference is possibly larger. For example: the difference between the body temperature indicated by the wearing state signal of the main earphone and the body temperature indicated by the wearing state signal of the auxiliary earphone is smaller than a first threshold value (the case that the user wears the main earphone and the auxiliary earphone at the same time), or the difference between the body temperature indicated by the wearing state signal of the main earphone and the body temperature indicated by the wearing state signal of the auxiliary earphone is larger than a second threshold value (the case that the user wears only the main earphone and does not wear the auxiliary earphone). When it is detected that a difference value between the body temperature of the wearer indicated by the wearing state signal of the primary earphone and the body temperature of the wearer indicated by the wearing state signal of the secondary earphone is between a first threshold and a second threshold, it may be determined that the wearers corresponding to the primary earphone and the secondary earphone are different, that is, the application scenario of the TWS bluetooth earphone is changed.

S604: and responding to the first scene change instruction, establishing a first SCO link between the terminal and the main earphone, and establishing a second SCO link between the terminal and the auxiliary earphone.

S605: and second audio data is transmitted between the terminal and the main earphone through the first SCO link, and second audio data is transmitted between the terminal and the auxiliary earphone through the second SCO link.

In the present application, the first scene change instruction may be an at (event) instruction. The AT command refers to a control command used in the bluetooth communication protocol. For example, an existing AT command may be multiplexed, and a certain information field in the existing AT command may be set to a value indicating a changed application scenario. An AT instruction may also be added to indicate a change situation of the application scenario.

Assume that a first scene change instruction is used to instruct the application scene of the TWS bluetooth headset to change to a simultaneous translation scene. In the present application, in the simultaneous interpretation scenario, the link established between the terminal and the bluetooth headset is different from the link established in the dialing scenario shown in fig. 5A. Under the simultaneous interpretation scene, the SCO link is established between the terminal and the main earphone as well as between the terminal and the auxiliary earphone. For convenience of description, in the embodiment of the present application, the SCO link between the terminal and the primary headset is referred to as a first SCO link, and the SCO link between the terminal and the secondary headset is referred to as a second SCO link.

After the first SCO link and the second SCO link are established, second audio data are transmitted between the terminal and the main earphone through the first SCO link, and second audio data are transmitted between the terminal and the auxiliary earphone through the second SCO link. The second audio data is voice call data. For example: the voice data can be the voice data in the voice call process of the user, and can also be the voice data in the video call process of the user.

The first SCO link and the second SCO link are both bidirectional links and can bidirectionally transmit voice data. For example, when the terminal sends voice data to the master earphone through the first SCO link, the master earphone may also send the voice data to the terminal through the first SCO link at the same time. When the terminal sends the voice data to the auxiliary earphone through the second SCO link, the auxiliary earphone can also send the voice data to the terminal through the second SCO link. The first SCO link and the second SCO link are independent and do not interfere with each other.

Therefore, the bluetooth communication method in the embodiment of the application can realize the switching of the application scenes of the TWS bluetooth headset in response to the first scene change instruction. The following describes a change of a link after switching from a listening music scene to a simultaneous interpretation scene, and a change of data transmission, with reference to fig. 7A and 7B.

Fig. 7A is a schematic diagram of a bluetooth headset switched from a music listening scene to a simultaneous interpretation scene according to an embodiment of the present application. As shown in fig. 7A, in a music listening scenario, a first ACL link is provided between the terminal and the main headset, and a second ACL link is provided between the main headset and the sub-headset. After the terminal receives the first scene change instruction, a first SCO link is established between the terminal and the main earphone, and a second SCO link is established between the terminal and the auxiliary earphone. Therefore, in the simultaneous interpretation scenario, two links exist between the terminal and the master earphone, which are the first ACL link and the first SCO link, respectively. And a second SCO link is arranged between the terminal and the auxiliary earphone. And a second ACL link is still formed between the main earphone and the auxiliary earphone.

In the simultaneous interpretation scene, the terminal has an interpretation function. After the terminal establishes SCO links with the main earphone and the auxiliary earphone, the user can use the Bluetooth earphone and the terminal to perform simultaneous interpretation. Specifically, the primary earphone collects second audio data of a first language, sends the second audio data of the first language to the terminal through the first SCO link, the terminal translates the second audio data of the first language into second audio data of a second language, sends the translated second audio data of the second language to the secondary earphone through the second SCO link, and the secondary earphone plays the second audio data of the second language. Meanwhile, the auxiliary earphone collects second audio data of a second language and sends the second audio data of the second language to the terminal through the second SCO link, the terminal translates the second audio data of the second language into second audio data of a first language and sends the translated second audio data of the first language to the main earphone through the first SCO link, and the main earphone plays the second audio data of the first language.

Fig. 7B is a schematic diagram of data transmission between a terminal and a bluetooth headset in a simultaneous interpretation scene provided in the embodiment of the present application. As shown in fig. 7B, user a wears the primary earphone and user B wears the secondary earphone. As shown by the solid line in fig. 7B, after being collected by the primary earphone, the voice data in the first language spoken by the user a is transmitted to the terminal through the first SCO link, the terminal translates the voice data into the second language, and transmits the translated voice data in the second language to the secondary earphone through the second SCO link, so that the user B can hear the voice data in the second language. Meanwhile, as shown by the dotted line in fig. 7B, after the voice data of the second language spoken by the user B is collected by the sub-headset, the voice data is transmitted to the terminal through the second SCO link, the terminal translates the voice data into the first language, and transmits the translated voice data of the first language to the main headset through the first SCO link, so that the user a can hear the voice data of the first language. Through the process, the simultaneous interpretation process of the user A and the user B is realized.

In the bluetooth communication method provided in this embodiment, a first ACL link is established between the terminal and the main earphone, and a second ACL link is established between the main earphone and the sub-earphone, in response to a first scene change instruction received by the terminal, a first SCO link is established between the terminal and the main earphone, and a second SCO link is established between the terminal and the sub-earphone. Make the terminal can be through transmitting voice data between first SCO link and the main earphone to through transmitting voice data between second SCO link and the auxiliary earphone, thereby realize that main earphone and auxiliary earphone gather two different users 'voice data respectively, and transmit for the terminal through different SCO links respectively and translate, realize the simultaneous interpretation process, richened bluetooth headset's application scene, satisfied the multi-functional demand of user to bluetooth headset.

Fig. 7A and 7B are schematic diagrams illustrating switching from a listening music scene to a simultaneous interpretation scene, and in practical applications, other scene switching situations may exist, for example: the single-person conversation scenario is switched to the double-person conversation scenario, which is described below with reference to fig. 8A and 8B.

Fig. 8A is a schematic diagram of a bluetooth headset switched from a single-person call scenario to a double-person call scenario according to an embodiment of the present application. As shown in fig. 8A, the bluetooth headset is in single-person talk mode before switching. For example: and the user A wears the main earphone and the auxiliary earphone simultaneously to carry out voice communication with the user C. During the call, the user a determines that it needs to switch to a double-person call scenario, and it is assumed that the user a wants to join the user B around the user a into the call. Illustratively, user a wears the sub-headset to user B, and user a inputs a first scene change instruction to the main headset or terminal. That is, after the double-person conversation scene is switched, the user a wears the main earphone, the user B wears the auxiliary earphone, and the user a and the user B use the same terminal to perform voice conversation with the user C.

As shown in fig. 8A, in the single-person call scenario, a first SCO link is between the terminal and the main earphone, and a third SCO link is between the main earphone and the sub-earphone. In this scenario, only the microphone of the primary earpiece collects audio data. The transmission process of the audio data is similar to that of fig. 5B, i.e., the microphone of the main headset takes the voice data of the user a and transmits the voice data to the terminal through the first SCO link. Thus, the terminal transmits the voice data to the user C. Meanwhile, the terminal receives the voice data of the user C and sends the received voice data to the main earphone through the first SCO link, the main earphone sends the received voice data to the auxiliary earphone through the second SCO link, the main earphone and the auxiliary earphone sound synchronously, and the user A receives and hears the speaking content of the user C through the main earphone and the auxiliary earphone.

With reference to fig. 8A, in the embodiment of the present application, after receiving a first scene change instruction input by a user, the terminal and the sub-headset establish a second SCO link. That is to say, after entering the double-person conversation scene, the first SCO link is still set between the terminal and the main earphone, the third SCO link is still set between the main earphone and the auxiliary earphone, and the second SCO link is newly added between the terminal and the auxiliary earphone.

Fig. 8B is a schematic diagram of data transmission between a terminal and a bluetooth headset in a double-person call scenario provided in the embodiment of the present application. As shown in fig. 8B, in a double-phone call scenario, the microphones of both the primary and secondary earphones collect audio data. Specifically, when the user a speaks, the main earphone collects the audio data of the user a, and sends the audio data of the user a to the terminal through the first SCO link, so that the terminal sends the audio data of the user a to the user C. When the user B speaks, the sub-headset collects the audio data of the user B and sends the audio data of the user B to the terminal through the second SCO link, and therefore the terminal sends the audio data of the user B to the user C. Of course, in some scenarios, the user a and the user C may also speak simultaneously, and therefore, the terminal mixes the audio data of the user a received through the first SCO link and the audio data of the user B received through the second SCO link, and then sends the mixed audio data to the user C.

In a double-person conversation scene, after receiving the voice data of the user C, the terminal sends the voice data to the main earphone through the first SCO link and sends the voice data to the auxiliary earphone through the second SCO link, so that the user A and the user B can both receive and hear the speaking content of the user C. Of course, in some scenarios, after receiving the voice data from the user C, the terminal may also send the voice data to the primary earphone through the first SCO link only, and the primary earphone forwards the audio data to the secondary earphone through the third SCO link.

In the above embodiments, in an implementation where the terminal receives the first scene change instruction from the TWS bluetooth headset, the TWS bluetooth headset transmits the first scene change instruction to the terminal in response to a first operation input by the user. The first operation may be input to the primary earphone by a user wearing the primary earphone, or input to the secondary earphone by a user wearing the secondary earphone. In the following, a detailed description is given in connection with two possible embodiments, respectively.

Fig. 9 is a schematic flowchart of entering a simultaneous interpretation mode according to an embodiment of the present application. As shown in fig. 9, the method includes:

s901: the master earphone receives a first operation input by a user.

Illustratively, the first operation is to instruct an application scenario of the TWS bluetooth headset to change to a simultaneous interpretation scenario.

For example, the user wearing the main headset may operate a mode switching button on the main headset, or the user wearing the main headset may input a preset voice command to the main headset, such as: the user inputs speech "enter into simultaneous interpretation mode" into the microphone of the primary earpiece.

S902: in response to the first operation, the primary earpiece transmits a physical address request message to the secondary earpiece.

S903: and the physical address of the auxiliary earphone is sent to the main earphone by the auxiliary earphone.

Illustratively, the primary earpiece may send a physical address request message to the secondary earpiece over the second ACL link. Accordingly, the secondary earpiece may send the physical address of the secondary earpiece to the primary earpiece over the second ACL link.

The physical address request message and the physical address of the sub-headset can be transmitted through an AT command.

S904: and the main earphone sends the first scene change instruction and the physical address of the auxiliary earphone to the terminal.

Illustratively, the primary earpiece sends a first scene change instruction to the terminal through the first ACL link, along with the physical address of the secondary earpiece. Correspondingly, the terminal receives a first scene change instruction and a physical address of the auxiliary earphone through the first ACL link.

The first scene change instruction and the physical address of the auxiliary earphone can be sent simultaneously or sequentially. For example, the first scene change instruction and the physical address of the auxiliary earphone are transmitted by an AT instruction, or the first scene change instruction is sent by the first AT instruction first, and then the physical address of the auxiliary earphone is sent by the second AT instruction. Or, the physical address of the auxiliary earphone is sent through the first AT instruction, and then the first scene change instruction is sent through the second AT instruction.

S905: and establishing a first SCO link between the terminal and the main earphone, and establishing a second SCO link between the terminal and the auxiliary earphone according to the physical address of the auxiliary earphone.

Through the above process, the SCO links are established between the terminal and the main earphone and between the terminal and the auxiliary earphone.

Fig. 10 is a schematic flowchart of another process for entering the simultaneous interpretation mode according to the embodiment of the present application. As shown in fig. 10, the method includes:

s1001: the sub-headset receives a first operation input by a user.

For example, the user wearing the sub-headset may operate a mode switching button on the sub-headset, or the user wearing the sub-headset may input a preset voice command to the sub-headset, such as: the user inputs the speech "enter the simultaneous interpretation mode" into the microphone of the sub-headset.

S1002: and responding to the first operation, the auxiliary earphone sends a first scene change instruction and the physical address of the auxiliary earphone to the main earphone.

Illustratively, the secondary earpiece sends the first scene change instruction to the primary earpiece over the second ACL link along with the physical address of the secondary earpiece. Correspondingly, the main earphone receives the first scene change instruction and the physical address of the auxiliary earphone through the second ACL link.

The first scene change instruction sent by the auxiliary earphone to the main earphone and the physical address of the auxiliary earphone can be transmitted through the AT instruction. The first scene change instruction and the physical address of the auxiliary earphone can be sent simultaneously or sequentially. For example, the first scene change instruction and the physical address of the auxiliary earphone are transmitted by an AT instruction, or the first scene change instruction is sent by the first AT instruction first, and then the physical address of the auxiliary earphone is sent by the second AT instruction. Or, the physical address of the auxiliary earphone is sent through the first AT instruction, and then the first scene change instruction is sent through the second AT instruction.

S1003: and the main earphone forwards the first scene change instruction and the physical address of the auxiliary earphone to the terminal.

Illustratively, the primary earpiece sends a first scene change instruction and a physical address of the secondary earpiece to the terminal through the first ACL link. Correspondingly, the terminal receives the first scene change instruction and the physical address of the auxiliary earphone through the first ACL link.

S1004: and establishing a first SCO link between the terminal and the main earphone, and establishing a second SCO link between the terminal and the auxiliary earphone according to the physical address of the auxiliary earphone.

In the above embodiments, after the SCO links are established between the terminal and the main earphone and between the terminal and the auxiliary earphone, the terminal may perform data transmission with the main earphone and the auxiliary earphone in a frequent manner. For example, while the terminal receives the audio data sent by the primary earphone through the first SCO link, the terminal may also receive the audio data sent by the secondary earphone through the second SCO link. The terminal can translate the audio data received through the first SCO link and can translate the audio data received through the second SCO link. The terminal can send the translated audio data to the main earphone through the first SCO link and can also send the translated audio data to the auxiliary earphone through the second SCO link.

In the embodiment of the application, the terminal is internally provided with the Bluetooth chip, and the Bluetooth chip is a chip which simultaneously supports two SCO links. The Bluetooth chip establishes contact with a Bluetooth software protocol stack layer through a Bluetooth driving layer. The bluetooth software protocol stack supports management of two SCO links. Illustratively, the bluetooth software protocol stack supports state maintenance for two SCO links. The Bluetooth software protocol stack also supports protocol processing of the audio data acquired from each SCO link and transmits the processed audio data to the audio processing device. Of course, the bluetooth software protocol stack also supports receiving audio data from the audio processing device and transmitting the received audio data onto the corresponding SCO link.

Wherein, two audio processing devices can be arranged in the terminal. The audio processing apparatus supports a translation process for audio data. One SCO link for each audio processing device. Illustratively, the audio processing apparatus 1 is configured to perform a translation process on audio data transmitted by the first SCO link. The audio processing device 2 is configured to perform a translation process on the audio data transmitted by the second SCO link.

In one possible implementation, each audio processing device includes: a receiver, a translator, and a sender. Illustratively, for the audio processing apparatus 1, the receiver is configured to receive audio data in a first language from a first SCO link, the translator is configured to translate the audio data in the first language to obtain audio data in a second language, and the transmitter is configured to transmit the translated audio data in the second language to a second SCO link. For the audio processing apparatus 2, the receiver is configured to receive the audio data in the second language from the second SCO link, the translator is configured to translate the audio data in the second language to obtain the audio data in the first language, and the transmitter is configured to transmit the translated audio data in the first language to the first SCO link.

Through set up two audio processing device in the terminal, realized that two SCO links all can two-way transmission data simultaneously, two SCO links are independent each other, do not influence each other for two users that use different languages can accessible exchange in real time. The following is described in detail with reference to a specific use scenario.

Fig. 11 is a schematic diagram of data transmission between a terminal and a bluetooth headset in a simultaneous interpretation scenario provided in the embodiment of the present application. Suppose user a uses chinese and user B uses english. The user A wears the main earphone, and the user B wears the auxiliary earphone.

As shown in fig. 11, the chinese speech spoken by user a is picked up by the microphone of the main headset and transmitted by the main headset to the receiver 1 of the terminal through the first SCO link. After receiving the Chinese speech, the terminal translates the Chinese speech into English speech through the translator 1, and then the transmitter 1 transmits the translated English speech to the auxiliary earphone through the second SCO link. Thus, the user B wearing the sub-headset hears the content of the speech of the user a.

The english speech spoken by user B is picked up by the microphone of the sub-headset and transmitted by the sub-headset via the second SCO link to the receiver 2 of the terminal. After receiving the English speech, the terminal translates the English speech into Chinese speech through the translator 2, and then the transmitter 2 transmits the translated Chinese speech to the main earphone through the first SCO link. Thus, the user a wearing the main earphone hears the content of the speech of the user B.

In a possible implementation manner, the translator may also be disposed in the cloud server. And after receiving the voice data to be translated, the terminal sends the voice data to be translated to the cloud server. And the cloud server returns the translated voice data to the terminal.

When a traditional translation device such as a translation stick is used by two users for conversation, the two users can not usually have real-time conversation. Specifically, when the user a speaks, the user a is required to select a first target language to be translated on the translation bar, and presses a recording button of the translation bar to record. After the recording is finished, the translation bar translates the recorded data into the first target language and plays the data, so that the user B can know the semantics of the user A by listening to the translated first target language. Similarly, when the user B speaks, the user B is required to select a second target language to be translated on the translator bar and press the recording button of the translator bar to record. After the recording is finished, the translation bar translates the recorded data into the second target language and plays the data, so that the user A can know the semantics of the user B by listening to the translated second target language. In the process, the user A and the user B need to use the translation rods alternately to perform the recording and playing operations respectively, so that the operation is complicated, and real-time conversation cannot be performed.

In the embodiment of the application, the SCO links are respectively established between the terminal and the main earphone and between the terminal and the auxiliary earphone, the two SCO links and the two translation paths are mutually independent and do not interfere with each other, and the two SCO links support the transmission of two-way voice data, so that two users using different languages can communicate in real time without barriers, and the effect of simultaneous interpretation is achieved.

In the embodiment of the application, the terminal can also receive translation configuration information input by a user. The translation configuration information indicates the capture language and/or the playback language of the primary and secondary earpieces. Illustratively, the user can reasonably set the translation configuration information according to the conversation scene and the language used by the conversation person, so that the terminal can perform translation processing according to the translation configuration information. In the following, a description is given in connection with two possible embodiments.

In one possible implementation, the terminal receives the collected language of the main earphone and the collected language of the auxiliary earphone input by the user. Fig. 12 is a schematic diagram of a translation configuration interface of a terminal according to an embodiment of the present application. As shown in fig. 12, the user sets the collection language of the primary earphone to be chinese and the collection language of the secondary earphone to be english. After the configuration, the terminal automatically takes Chinese as the playing language of the main earphone and English as the playing language of the auxiliary earphone. Namely, the terminal translates the Chinese collected from the main ear into English, and the English is played by the auxiliary ear phone. The terminal translates English picked up by the auxiliary earphone into Chinese and plays the Chinese by the main earphone.

In another possible implementation, the terminal receives the play language of the primary earphone and the play language of the secondary earphone input by the user. Fig. 13 is a schematic diagram of a translation configuration interface of a terminal according to an embodiment of the present application. As shown in fig. 13, the user sets the language of the primary earphone to be chinese and the language of the secondary earphone to be english. After the configuration, the terminal automatically takes Chinese as the collection language of the main earphone and English as the collection language of the auxiliary earphone. Namely, the terminal translates the Chinese collected from the main earphone into English, and the English is played by the auxiliary earphone. The terminal translates English picked up by the auxiliary earphone into Chinese and plays the Chinese by the main earphone.

The terminal can be flexibly applied to various application scenes by performing translation processing according to the translation configuration information set by the user.

Certainly, the terminal can also automatically recognize the pickup voices of the main earphone and the auxiliary earphone, so that the intelligent translation processing is performed, the user operation is simplified, and the user experience is improved. For example, assume that user a wears a primary headset and user B wears a secondary headset. Before user a and user B have a formal conversation, user a and user B may first input a test voice to the terminal. And the terminal determines the acquisition language of the main earphone according to the test voice input by the user A. And the terminal determines the acquisition language of the auxiliary earphone according to the test voice input by the user B. For example: the test voice input by the user A is 'I am ok', and the test voice input by the user B is 'I am ok'. The terminal may determine that the collection language of the primary earphone is chinese and the collection language of the secondary earphone is english. Further, the terminal automatically translates the Chinese collected from the main ear into English, and the English is played by the auxiliary ear. The terminal translates English picked up by the auxiliary earphone into Chinese and plays the Chinese by the main earphone.

In the embodiment of the application, after the translation is finished, the user can exit the simultaneous interpretation mode through the operation terminal or the TWS Bluetooth headset. This will be described with reference to fig. 14.

In some embodiments, the TWS bluetooth headset receives a second operation input by the user to the TWS bluetooth headset, and in response to the second operation, the TWS bluetooth headset transmits a second scene change instruction to the terminal. Illustratively, when the user needs to end the simultaneous interpretation, the second operation may be input to the bluetooth headset in various ways. In one possible embodiment, the user may operate a mode switch button. Illustratively, the user may click the mode switch button, or double click the mode switch button, or touch the mode switch button. In another possible embodiment, the user may input a preset voice command to the bluetooth headset, for example, the user inputs a voice "exit the simultaneous interpretation mode" to the bluetooth headset.

In one possible scenario, the primary earphone receives a second operation input by the user, and in response to the second operation, the primary earphone sends a second scene change instruction to the terminal through the first ACL link. Correspondingly, the terminal receives the second scene change instruction through the first ACL link.

In another possible scenario, the secondary earphone receives a second operation input by the user, and in response to the second operation, the secondary earphone sends a second scene change instruction to the primary earphone through the second ACL link. And the main earphone forwards the received second scene change instruction to the terminal through the first ACL link.

In this application, the second scene change instruction may be an AT instruction. For example, an existing AT command may be multiplexed, with some field of information in the existing AT command set to a value indicating exit from the simultaneous translation mode. An AT instruction can be added to indicate to exit the simultaneous translation mode.

In other embodiments, the terminal receives a second scene change instruction input by the user. The user may input the second scene change instruction to the terminal in various ways, similar to the way the user inputs the first scene change instruction to the TWS bluetooth headset. For example: and inputting a second scene change instruction to the terminal in a terminal interface by clicking a mode switching control, double-clicking a mode switching control, touching the mode switching control, sliding the mode switching control and the like. The second scene change instruction may also be input to the terminal by means of voice interaction, for example, inputting a voice "exit the simultaneous interpretation mode" to the terminal.

And a second SCO link is arranged between the terminal and the auxiliary earphone. And a second ACL link is arranged between the main earphone and the auxiliary earphone. And after the terminal receives the second scene change instruction, the terminal disconnects a first SCO link with the main earphone and disconnects a second SCO link with the auxiliary earphone. Therefore, after the simultaneous interpretation mode is exited, a first ACL link is formed between the terminal and the main earphone, and no connection link is formed between the terminal and the auxiliary earphone. And a second ACL link is still formed between the main earphone and the auxiliary earphone. That is, after the simultaneous interpretation is finished, the link between the terminal and the bluetooth headset is restored to the link state in the music listening scene as shown in fig. 4. Therefore, the Bluetooth headset is convenient for a user to normally use.
