The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

The invention provides an in-vehicle multi-audio playing method based on earphones, and as shown in a flow chart of a figure 1, a path is added in an original audio path of an in-vehicle control system, the added path is connected with the earphones, and the earphones can be vehicle-mounted Bluetooth earphones. The method adds a type in the original Android audio channel by modifying the code of the Android Framework layer, and specifies the type to be used for a special Bluetooth device (the device is a customized vehicle-mounted Bluetooth headset, and the vehicle-mounted Bluetooth headset is exemplified in the following description process of the invention).

Further comprising the steps of:

and step S10, determining the application needing to play the audio in the control system. In the invention, an Android Bluetooth application (application) is installed in a control system (Android system), and the application can read the application installed in the Android system. The control system may be an Android system, and the application may be an application installed in the Android system, and the application includes: navigation APP, music APP and the like, such as a Gade map, Google map, QQ music, Internet cloud music and the like.

Step S20, obtaining application information of the determined application, wherein the application information includes one or more audios of the application, and the audios respectively correspond to any one of an earphone playing mode and a car machine playing mode.

Before step S20, the method further includes:

In the application layer App, a setting option is provided, a user can input corresponding configuration information through the setting option, and the audio frequency respectively included by all application Apps in the current Android system is set in a user-defined mode to be specifically played through which equipment.

And step S30, judging whether the earphone is in a use state at the current time.

In step S30, as shown in fig. 2, the method further includes the steps of:

s301, acquiring the use information of the earphone;

s302, judging whether the use information reaches a preset condition;

s303, if the earphone reaches a preset condition, the earphone is in a use state;

s304, if the earphone does not reach the preset condition, the earphone is not in a use state.

The using state of the earphone is judged through the above mode, if the earphone reaches the preset condition, the earphone is in the using state, the earphone is worn by the driver, if the earphone does not reach the preset condition, the earphone is not in the using state, and the driver does not wear the earphone at the moment.

The car machine bluetooth application App transmits the current bluetooth device status to the car machine Framework layer (exemplified by the headset status as to whether to play the mobile phone audio, whether to talk, whether to be picked up for wearing, whether to be put in the charging bin). Whether the earphone reaches the preset condition is any one or more of whether the earphone plays the mobile phone audio, whether the earphone is in a call, whether the earphone is taken up to be worn and whether the earphone is placed in the charging bin.

And step S40, if the current time is in the state of the audio playing mode, the audio corresponding to the earphone playing mode at the current time is played through the earphones, and the audio corresponding to the car machine playing mode at the current time is played through the car machine. Adding logic judgment in the Framework layer, judging the current state of the earphone when the corresponding application starts to play audio by reading the content of the configuration file, and playing different audio in the application through different equipment if the earphone state is consistent.

And step S50, if not, mixing all audio applied and output at the current moment and then playing the audio through the vehicle machine. When the earphone is in use, audio to be played by different devices is mixed, and then played by a default device (vehicle machine).

Through the mode, different audios output by the same application can be played for different devices, for example, one application plays two audios simultaneously, one audio is navigation information (for a driver to listen), the other audio is safety prompt type information (for a passenger to listen), the earphone is in a use state (a situation that the driver wears), the earphone plays the audio corresponding to the navigation information, and the car machine plays the audio corresponding to the safety prompt type information. Reach two audios respectively can be accurate output for different personnel in the car to can not carry out mutual interference between two audios.

In one embodiment, the Android system is an example of a vehicle-mounted central control system, and the special bluetooth device is an example of an intelligent vehicle-mounted bluetooth headset, and the special bluetooth headset has the following usage scenarios, which respectively include:

usage scenario 1

When the bluetooth headset is worn with the bluetooth headset in a pick-up state, only the application a runs, and the audio M1 and the audio M2 are contained in the application a. When the audio M1 and the audio M2 are played simultaneously, the audio M1 calls the application App interface when playing. The audio M2 uses a system interface.

At this time, the App is used for transmitting the audio M1 to the Framework, and when the Framework judges that the current earphone state is picked up and worn, the audio M1 is not subjected to audio mixing processing and is directly played through a spaker of the earphone.

The audio M2 is directly played through a vehicle player.

Usage scenario 2

When the Bluetooth headset is picked up and worn, the application A and the application B are simultaneously operated. Application A contains audio M1 and audio M2, and application B contains audio M3. When the audio M1, M2, and M3 are played simultaneously, wherein the audio M1 calls the application App interface described above when playing, the audio M2, M3 use the system interface.

The audio M2 and M3 are mixed by the system and played by a vehicle player.

Usage scenario 3

The bluetooth headset is placed in the charging bay when only app a is running and app a contains audio M1 and audio M2. When the audio M1 and the audio M2 are played simultaneously, wherein the audio M1 calls the application App interface described above when playing, the audio M2 uses the system interface.

At this time, the App is used for transmitting the audio M1 to the Framework, and when the Framework judges that the current earphone state is placed in the charging bin, the audio M1 and the audio M2 are subjected to mixing processing through the system and are played through a vehicle spaker.

Usage scenario 4

The bluetooth headset is placed in the storehouse of charging, runs application A and application B simultaneously. Application A contains audio M1 and M2, and application B contains audio M3. When the audio M1, M2, and M3 are played simultaneously, wherein the audio M1 calls the application App interface described above when playing, the audio M2, M3 use the system interface.

At this time, the App is used for transmitting the audio M1 to the Framework, and when the Framework is placed in the charging bin when the current earphone state is judged, the audio M1, the audio M2 and the audio M3 are subjected to sound mixing processing through the system and are played through a vehicle player.
