Detailed Description

Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and should be considered as merely exemplary. Accordingly, one of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a flowchart of a method for playing audio data according to an embodiment of the present application. The embodiment is suitable for the situation of how to play the audio data of the application program in the user terminal in the Bluetooth connection process of the user terminal and the vehicle-mounted terminal. The embodiment may be performed by a user terminal, in particular by a playback device of audio data configured in the user terminal, which device may be implemented in software and/or hardware. The user terminal may be an electronic device with bluetooth connection function, such as a smart phone, a tablet computer, a wearable device, etc. As shown in fig. 1, the method includes:

s101, if a local audio playing event of an application program in the user terminal is monitored in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, switching from a Bluetooth channel to a loudspeaker channel.

In this embodiment of the present application, the application program in the user terminal may be an application program installed on the user terminal and capable of playing audio, for example, may be a music application program, a video application program, a navigation application program, and the like. Alternatively, the application program in the embodiment of the present application may be all application programs installed in the user terminal and capable of playing audio, and may also be one or more target application programs specified from all application programs capable of playing audio. This embodiment is not limited. The local audio playing event of the application program may be an event triggered when the user terminal needs to locally play the audio of the application program in the process that the user terminal maintains bluetooth connection with the vehicle-mounted terminal.

Optionally, in this embodiment, the execution manner of detecting the local audio play event of the application program in the user terminal may be: in the process that the user terminal is connected with the Bluetooth of the vehicle-mounted terminal, a voice broadcasting function of the application program is started, and the vehicle-mounted terminal has audio being broadcast at the moment, so that a local audio broadcasting event of the application program can be triggered and monitored. For example, in the process of connecting the user terminal and the vehicle-mounted terminal through bluetooth, a navigation broadcasting function of the navigation application program is started, and the vehicle-mounted terminal is broadcasting a radio station at the moment, and in the scene, a local audio broadcasting event of the navigation application program can be triggered and monitored. The method can also be that the voice broadcasting function of the application program is started in the Bluetooth connection process of the user terminal and the vehicle-mounted terminal, and the fact that the user selects a loudspeaker to play in the playing configuration item is monitored, and at the moment, a local audio playing event of the application program is triggered and monitored. For example, in the process of connecting the user terminal and the vehicle-mounted terminal through Bluetooth, a navigation broadcasting function of the navigation application program is started, and a user starts a speaker broadcasting configuration item in a configuration item of the navigation application program in advance or when starting navigation, and in the scene, a local audio broadcasting event of the navigation application program can be triggered and monitored.

The speaker channel in the embodiment of the present application may be a channel for amplifying audio data locally and outwards by the user terminal. The bluetooth channel may be a channel through which the user terminal transmits data to the vehicle-mounted terminal after the user terminal is connected with the vehicle-mounted terminal via bluetooth. The bluetooth channels may include synchronous channels (Synchronous Connection Oriented, SCO) and asynchronous channels (Asynchronous Connectionless, ACL). It should be noted that, for the call audio (such as audio in the process of making a call) of the user terminal, the call audio is generally transmitted to the vehicle-mounted terminal through a synchronization channel for playing; for application audio (e.g., songs, navigation guidance information, etc.) of the user terminal, both channels (i.e., synchronous channel and asynchronous channel) may be transmitted to the vehicle terminal for playback.

Optionally, in the process that the user terminal and the vehicle-mounted terminal maintain bluetooth connection, if a local audio playing event of an application program in the user terminal is monitored, the embodiment of the application program may switch from a bluetooth channel to a speaker channel. Specifically, if the synchronous channel of the bluetooth channel is used in the process of maintaining the bluetooth connection between the current user terminal and the vehicle-mounted terminal, the synchronous channel of the bluetooth channel can be switched to the speaker channel at the moment; if the asynchronous channel of the Bluetooth channel is used in the process of keeping the Bluetooth connection between the current user terminal and the vehicle-mounted terminal, the asynchronous channel of the Bluetooth channel can be switched to the loudspeaker channel at the moment. When the synchronous channel of the Bluetooth channel is switched to the speaker channel, the synchronous channel is closed, the speaker channel is ensured to be in an open state, and at the moment, the synchronous channel of the Bluetooth channel can be switched to the speaker channel. When the asynchronous channel of the Bluetooth channel is switched to the loudspeaker channel, the asynchronous channel is in a normally open state, so that the asynchronous channel of the Bluetooth channel can be switched to the loudspeaker channel only by ensuring that the loudspeaker channel is in an open state. It should be noted that, a specific setting method for switching from a bluetooth channel to a speaker channel will be described in detail in the following embodiments.

S102, setting the audio mode of the audio manager of the user terminal as a call mode.

The audio manager may be a tool in the user terminal that can set audio related parameters, and the operation is to set an audio mode in the audio manager. Optionally, the audio modes in the audio manager may include: normal mode and talk mode.

Optionally, in the process that the user terminal and the vehicle-mounted terminal keep bluetooth connection, the user terminal system automatically sets the audio mode of the audio manager to a common mode, and when an application program of the user terminal is to play audio (such as songs, navigation guidance information and the like), the audio is transmitted to the vehicle-mounted terminal through an asynchronous channel of a bluetooth channel by default for playing; when a call event (such as telephone access) occurs, the user terminal system automatically sets the audio mode of the audio manager to be a call mode, and opens the synchronous channel of the Bluetooth channel, and at the moment, call audio is transmitted to the vehicle-mounted terminal for playing by default through the synchronous channel. In the process that the user terminal and the vehicle-mounted terminal keep Bluetooth connection, the local audio playing event is monitored and is not a call event, so that the user terminal system cannot default to automatically set an audio mode to be a call mode and also cannot default to automatically start a synchronous channel of a Bluetooth channel. So after S101 switches from the bluetooth channel to the speaker channel, playing the audio of the application program through the speaker channel of the user terminal still cannot be realized, and the audio mode of the audio manager needs to be set to the call mode by active triggering.

Optionally, the call mode further includes a telephone mode and a communication mode. Specifically, IN this embodiment, when setting the Audio Mode (Audio Mode) of the Audio Manager (Audio Manager) of the user terminal to the CALL Mode, it may be determined whether the interface version number (Android API) of the user terminal is smaller than a preset version number (e.g. 21), if so, the Audio Mode of the Audio Manager of the user terminal is set to be the phone Mode (mode_in_call), and if so, the Audio Mode of the Audio Manager of the user terminal is set to be the COMMUNICATION Mode (mode_in_communication).

S103, playing the audio of the application program through the speaker channel.

The audio of the application program may be audio data to be played by the application program, for example, when the application program is a navigation application program, the audio of the application program may be navigation induction information, that is, navigation voice played in a navigation process for guiding a user to travel.

Optionally, in the whole operation process of the embodiment of the present application, the user terminal and the vehicle bluetooth are always connected, S102 also sets the audio mode of the audio manager of the user terminal to a call mode, at this time, because the asynchronous channel of the bluetooth channel cannot play the audio of the application program in the call mode, and no call event triggers the synchronous channel of the bluetooth channel to start, at this time, the bluetooth channel cannot play the audio of the application program, and the user terminal can only play the audio of the application program through the speaker. Therefore, when a user drives the vehicle, the audio of the application program is played through the loudspeaker of the user terminal under the condition that the Bluetooth connection with the vehicle-mounted terminal is not disconnected, and the vehicle-mounted audio is played through the vehicle-mounted terminal. The situation that the vehicle-mounted audio frequency and the application program audio frequency conflict under the condition that the user terminal is connected with the vehicle-mounted Bluetooth is avoided, and the connection between the user terminal and the vehicle-mounted Bluetooth is not disconnected in the whole process, so that when a telephone is accessed, the user terminal can still answer through the vehicle-mounted equipment, and the driving safety is considered. Optionally, the application program of the user terminal in the embodiment of the present application is preferably a navigation application program, and audio of the application program is navigation guidance information. Therefore, the vehicle-mounted music (such as radio broadcasting) is listened to through the vehicle-mounted terminal, and the navigation induction information is listened to through the loudspeaker of the user terminal.

According to the technical scheme, in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, if a local audio playing event of an application program is monitored, a Bluetooth channel is switched to a speaker channel, an audio mode of an audio manager is set to be a call mode, and then audio of the application program is played through a speaker. According to the scheme, in the process that the Bluetooth connection process of the user terminal and the vehicle-mounted terminal is always kept, the speaker can play the audio of the application program, the vehicle-mounted terminal is supported to play the vehicle-mounted audio, the problem that the vehicle-mounted terminal simultaneously plays the vehicle-mounted audio and the audio of the application program conflicts when the user terminal is connected with the Bluetooth connection process of the vehicle-mounted terminal is solved, and a new idea is provided for audio data playing in the process that the user terminal is connected with the Bluetooth connection process of the vehicle-mounted terminal.

Further, in the embodiment of the present application, after switching from the bluetooth channel to the speaker channel, the method may further include: and setting the audio stream type of the media player of the user terminal as a music type. Among these, there are many types of audio streams (stem Type), which may include, for example, a call voice Type, a system alert Type, a bell sound Type, a music Type, and the like. When the audio volume control device is set to be of a certain type, the audio volume control device is only used for adjusting the audio volume of the certain type, and the influence on the audio volume of other types can be avoided. Alternatively, since the audio of the application belongs to the music playing sound, the present embodiment may set the audio stream type of the media player to the music type, for example, when the application is a navigation application, the audio stream type of the application is set to the music type for the navigation guidance information in the form of voice converted from the navigation guidance information in the form of text, which has the advantage that the user can flexibly control the size of the audio playing volume of the application through the volume adjustment key of the user terminal.

Further, in the embodiment of the present application, after switching from the bluetooth channel to the speaker channel, the method may further include: and if the speaker of the user terminal is detected to be closed, opening the speaker. Specifically, in order to avoid the situation that the speaker is turned off due to the failure of the user terminal system or software, it is ensured that after the bluetooth channel is switched to the speaker channel, the speaker of the user terminal can normally play the audio of the application program, that is, the user terminal monitors whether the speaker is turned off, and if so, the speaker is turned on from the audio manager, thereby ensuring that the audio of the application program can be normally played through the speaker.

Fig. 2A is a flowchart of another audio data playing method according to an embodiment of the present application; fig. 2B-2D are interface diagrams of a setup function of a navigation application provided according to an embodiment of the present application. The embodiment further optimizes the above embodiments, and gives a specific description of how to generate a local audio playback event of an application program in a user terminal, as shown in fig. 2A-2D, and the method includes:

s201, monitoring whether a speaker playing configuration item of the user terminal is in an on state or not when the user terminal and the vehicle-mounted terminal are in Bluetooth connection, and after a voice broadcasting function of an application program is started, and generating a local audio playing event according to a monitoring result.

The voice broadcast function of the application program may be a function of playing audio by the application program, for example, when the application program is a navigation application program, the navigation function is a voice broadcast function thereof.

Optionally, in an embodiment of the present application, a play channel configuration option is provided on a configuration interface of the application, where the play channel configuration option includes: speaker play configuration item, synchronous channel play configuration item and asynchronous channel play configuration item of bluetooth channel. For example, as shown in fig. 2B, which shows an effect schematic diagram of an auxiliary function setting interface of a navigation application, the bluetooth connection setting option in fig. 2B is a play channel configuration option, and the bluetooth device in the option broadcasts (recommends) an asynchronous channel play configuration item of a bluetooth channel; the Bluetooth equipment broadcasts (selectable when broadcasting silence) a synchronous channel play configuration item which is a Bluetooth channel; and broadcasting the speaker of the mobile phone to obtain a speaker playing configuration item. Optionally, the speaker play configuration item of the user terminal may be preset by the user in a setting page (such as the interface shown in fig. 2B) of the application client; the setting may also be set by the user in a setting option in the playing audio interface, for example, clicking on the "more settings" option in the navigation interface of the navigation application program shown in fig. 2C may also enter a setting interface (such as the interface shown in fig. 2D), where fig. 2D is similar to fig. 2B, and there is a bluetooth connection setting option.

Optionally, in this embodiment, when the user terminal monitors that the voice broadcast function of the application program is started in the process of maintaining the bluetooth connection between the user terminal and the vehicle-mounted device, whether the user selects a speaker play configuration item in advance in a setting page (an interface shown in fig. 2B) of the application program needs to be further monitored, and if so, the monitoring result is that the speaker play configuration item is in an on state. If the asynchronous channel playing configuration item or the synchronous channel playing configuration item is selected in advance in the setting page of the application program by the user, the monitoring result is that the loudspeaker playing configuration item is in a closed state. The embodiment includes the following two cases when generating an audio play event according to the monitoring result:

in the first case, if the speaker playing configuration item is in an on state, a local audio playing event is generated. Specifically, in this case, if the user terminal monitors that the user has preselected the speaker playing configuration item in the setting interface (such as the interface shown in fig. 2B) of the application program, the speaker playing configuration item is already in an on state due to the presettings, which indicates that the user's requirement is that the audio of the application program is selected to be played through the speaker under the condition that the user terminal is connected with the bluetooth of the vehicle-mounted terminal. At this point a local audio play event may be touched.

And secondly, if the speaker playing configuration item is in a closed state, responding to the switching operation of the speaker playing configuration item on the operation interface of the application program by a user, starting the speaker playing configuration item, and generating a local audio playing event. Specifically, in this case, if the user terminal monitors that the user does not select the speaker playing configuration item in the setting interface (such as the interface shown in fig. 2B) of the application program, the speaker playing configuration item is in a closed state at this time, which indicates that the user needs to select to play the audio of the application program through the vehicle-mounted terminal under the condition that the user terminal is connected with the vehicle-mounted terminal through bluetooth. The user terminal needs to play the audio of the application program at the vehicle-mounted terminal according to the play configuration item selected by the user at this time. In the audio playing process of the application program, if the switching operation of the loudspeaker playing configuration item triggered by the user on the operation interface of the application program, namely the operation interface of the voice broadcasting function of the application program, the switching operation of the loudspeaker playing configuration item is responded, the loudspeaker configuration item is started, and then a local audio playing event occurs in a touching mode.

For example, in the navigation process, the user clicks more setting keys on the navigation interface shown in fig. 2C, and after entering the more setting operation interface shown in fig. 2D, clicks the speaker play option of the mobile phone, at this time, the user terminal responds to the switching operation of clicking the speaker play option of the mobile phone by the user, opens the speaker play configuration item, and generates a local audio play event.

S202, if a local audio playing event of an application program in the user terminal is monitored, switching from a Bluetooth channel to a loudspeaker channel.

S203, setting the audio mode of the audio manager of the user terminal as a call mode.

S204, playing the audio of the application program through the speaker channel.

According to the technical scheme, in the process that the Bluetooth connection is kept between the user terminal and the vehicle-mounted terminal, after the voice broadcasting function of the application program is started, whether the loudspeaker playing configuration of the user terminal is in an on state or not is monitored, a local audio playing event is generated according to the monitoring result, after the local audio playing event of the application program is monitored, a Bluetooth channel is switched to a loudspeaker channel, an audio mode of an audio manager is set to be a call mode, and then application program audio is played through a loudspeaker. According to the scheme of the embodiment, whether the local audio playing event occurs is determined according to whether the broadcasting function of the application program and the loudspeaker playing configuration item are started or not, a user can select whether to start the loudspeaker playing configuration item or not according to own requirements, personalized requirements of the user can be better met, and whether to switch to a mobile phone loudspeaker channel to play the audio of the application program or not is selected according to actual requirements of the user. In addition, when the user selects whether to start the speaker playing configuration item, the speaker playing configuration item can be selected in advance, or can be selected in real time after the voice broadcasting function is started, so that the flexibility is higher. A new idea is provided for playing audio data in the process of connecting the user terminal with the vehicle-mounted Bluetooth.

Fig. 3 is a flowchart of another audio data playing method according to an embodiment of the present application. The embodiment is further optimized based on the above embodiments, and provides an introduction of how to answer the incoming call in the process of playing the audio of the application program through the speaker. As shown in fig. 3, the method includes:

s301, if a local audio playing event of an application program in the user terminal is monitored in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, switching from a Bluetooth channel to a loudspeaker channel.

S302, setting the audio mode of the audio manager of the user terminal as a call mode.

And S303, playing the audio of the application program through the speaker channel.

And S304, if the call event of the user terminal is monitored, stopping playing the audio of the application program.

The call event may be an event triggered and generated when the user terminal has a phone access.

Optionally, in the embodiment of the present application, if a call event of the user terminal is monitored during the process that the user terminal plays the audio of the application through the speaker, that is, when the user terminal has a phone access, in order to prevent a play conflict between the audio of the application and the phone audio, the audio of the application may be stopped, and a service of answering the phone is preferentially provided for the user.

S305, switching from the speaker channel to the synchronization channel of the bluetooth channel.

Optionally, in the process of executing the above S301-S303, although the audio of the application program is played through the speaker of the user terminal, the bluetooth connection between the user terminal and the vehicle-mounted terminal is not disconnected, and in this case, in order to ensure the driving safety of the vehicle, the embodiment should preferably provide a service of answering the call for the user through the synchronization channel of the bluetooth channel of the vehicle terminal. Since the user terminal plays audio through the speaker before the call event of the user terminal is monitored, the speaker channel of the user terminal is switched to the synchronous channel of the bluetooth channel at this time. Since the audio mode of the audio manager is set to the talk mode before the audio of the application program is played through the speaker channel and the required audio mode is also the talk mode when the talk audio is played through the synchronization channel in this embodiment, the audio mode may not be set at this time, or the operation of setting the audio mode of the audio manager of the user terminal to the talk mode may be performed again in order to ensure the accuracy of the audio mode.

Optionally, since the synchronization channel of the bluetooth channel of the user terminal is in a closed state during the audio playing process of the application program through the speaker channel, when the speaker channel is to be switched to the synchronization channel of the bluetooth channel, it is required to detect whether the user terminal supports the synchronization channel of the bluetooth channel, if so, the synchronization channel of the bluetooth channel is opened, and then the switching of the speaker channel to the synchronization channel of the bluetooth channel is performed.

Alternatively, when switching from the speaker channel to the synchronous channel of the bluetooth channel, the speaker of the user terminal may be turned on if the speaker is detected to be turned off. To avoid the situation that the speaker is turned off due to the malfunction of the user terminal or the application program. The loudspeaker of the user terminal is ensured to be in a normally-open state.

S306, transmitting the call audio of the user terminal to the vehicle-mounted terminal for playing through the synchronous channel.

Optionally, after the speaker channel is switched to the synchronization channel of the bluetooth channel, the current call audio of the user terminal can be sent to the vehicle-mounted terminal through the synchronization channel because the audio mode of the audio manager is also a call mode at this time, so that the vehicle-mounted terminal plays the call audio, and a call service is provided for the user.

Optionally, the user terminal in this embodiment may further monitor whether the call is finished in real time during the call passing, and if the call is finished and the voice broadcast of the application program is not finished yet, switch from the synchronization channel of the bluetooth channel to the speaker channel, and continue playing the audio of the application program through the speaker channel. The specific implementation process of switching from the synchronous channel of the bluetooth channel back to the speaker channel will be described in detail in the following embodiments.

According to the technical scheme, in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, if a local audio playing event of an application program is monitored, a Bluetooth channel is switched to a speaker channel, an audio mode of an audio manager is set to be a call mode, and then audio of the application program is played through a speaker. If the call event is detected when the audio of the application program is played, the audio of the application program is stopped being played, the loudspeaker channel is switched to the synchronous channel of the Bluetooth channel, and the call audio is played at the vehicle-mounted terminal through the synchronous channel. According to the scheme, after the local play event of the application program is monitored, although the audio of the application program is played locally at the user terminal through the loudspeaker, bluetooth connection between the user terminal and the vehicle-mounted terminal is not disconnected, when a call event is monitored, the synchronous channel of the Bluetooth channel is still automatically switched, and a call is answered through the vehicle-mounted device, so that the problem that the vehicle-mounted audio and the audio of the application program are in conflict when the vehicle-mounted terminal is simultaneously played under the condition that the user terminal is connected with the Bluetooth of the vehicle-mounted terminal is solved, and driving safety is also considered.

Preferably, in this embodiment, when switching from the speaker channel to the synchronization channel of the bluetooth channel, if the user terminal supports the synchronization channel of the bluetooth channel, the monitoring process is registered; setting the audio connection state of the synchronous channel of the audio manager to be on; if the audio connection state of the synchronous channel is monitored to be on through the monitoring process, setting the synchronous channel of the audio manager to be on; switching from a speaker channel to the synchronization channel. Specifically, a process broadcasted by the monitoring system may be registered first, and the process is used for monitoring whether the audio connection state of the synchronization channel is updated, such as whether the audio connection state is updated from a closed state to an open state. The audio connection state of the synchronization channel of the audio manager is then set to on. If the starting is successful, the process broadcasted by the monitoring system registered before monitors that the audio connection state of the synchronous channel is updated to be started, at the moment, the synchronous channel of the audio manager is set to be in the starting state, and then the synchronous channel is switched from the loudspeaker channel to the synchronous channel. The advantage of this arrangement is that it is possible to avoid that the synchronization channel in the closed state is erroneously set to the open state when the audio connection state of the synchronization channel of the audio manager fails to open. The situation that the call voice is played silently occurs, so that the call quality of answering the call through the vehicle-mounted terminal is ensured.

Fig. 4 is a flowchart of another audio data playing method according to an embodiment of the present application. The embodiment is further optimized based on the above embodiments, and an introduction of how to operate after the audio of the application program is played through the speaker is given. As shown in fig. 4, the method includes:

s401, if a local audio playing event of an application program in the user terminal is monitored in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, switching from a Bluetooth channel to a loudspeaker channel.

S402, setting the audio mode of the audio manager of the user terminal as a call mode.

S403, playing the audio of the application program through a speaker channel.

S404, if the audio playing end event of the application program is monitored, switching from the speaker channel to the asynchronous channel of the Bluetooth channel, and setting the audio mode of the audio manager to the normal mode.

The audio play end event of the application program may be an event triggered and generated when the application program exits, or may be an event triggered and generated when the audio play function of the application program is closed, for example, if the application program is a navigation application program, the audio play end event of the navigation application program may be triggered and generated when the navigation application program is closed; it is also possible to generate an audio play end event of the navigation application after each navigation end.

Optionally, when the user terminal is connected with the vehicle-mounted terminal by bluetooth, the user terminal system defaults to automatically open an asynchronous channel of the bluetooth channel, and when a call event is monitored, the system defaults to automatically open a synchronous channel. Therefore, when the audio playing end event of the application program is monitored, the embodiment needs to switch the speaker channel to the asynchronous channel which is normally opened by default, and the audio mode of the audio manager is set to the normal mode at this time because the asynchronous channel needs to play the audio data of the normal mode.

Alternatively, when the speaker channel is switched to the asynchronous channel, the audio stream type of the media player of the user terminal may be set to the music type. So that when the audio is played through the asynchronous channel later, the user can flexibly control the volume of the audio playing through the volume adjusting key of the user terminal. Alternatively, the speaker may be turned on if it is detected that the speaker of the user terminal is turned off. To avoid the situation that the speaker is turned off due to the malfunction of the user terminal or the application program. The loudspeaker of the user terminal is ensured to be in a normally-open state.

According to the technical scheme, in the process that the user terminal and the vehicle-mounted terminal are in Bluetooth connection, if a local audio playing event of an application program is monitored, a Bluetooth channel is switched to a speaker channel, an audio mode of an audio manager is set to be a call mode, and then audio of the application program is played through a speaker. Upon monitoring an audio playback end event of the application, switching from the speaker channel to the asynchronous channel of the bluetooth channel and setting the audio mode of the audio manager to the normal mode. When detecting a local audio playing event of an application program, the scheme of the embodiment switches to a loudspeaker to play the audio of the application program; after the audio playing is finished, the conventional Bluetooth asynchronous channel is restored. The method and the device can realize the flexible switching of the playing channel according to the user requirements in the Bluetooth connection process of the user terminal and the vehicle-mounted terminal, and provide a new idea for playing the audio data of the user terminal.

The present embodiment provides a description of a specific setting manner of the bluetooth channel and the speaker channel during switching based on the foregoing embodiments. Specifically, in this embodiment, the user terminal is taken as an Android (Android) system as an example to be described:

the asynchronous channel of the first scene and the Bluetooth channel is switched to the scene of the loudspeaker channel. The specific switching setting mode comprises the following three steps:

1) The audio mode of the audio manager of the user terminal is set to a talk mode. Specifically, it is determined whether the interface version number (Android API) of the user terminal is smaller than a preset version number (e.g., 21), if the interface version number is smaller than the preset version number, the audio MODE of the audio manager of the user terminal is set to be a phone MODE (mode_in_call), and if the interface version number is greater than or equal to the preset version number, the audio MODE of the audio manager of the user terminal is set to be a COMMUNICATION MODE (mode_in_communication).
