The technical scheme in the embodiment of the application has the following general idea: a method for generating double-screen different sound is provided for two different display mechanisms, for the different double-screen different display mechanisms completed by different applications, the equipment is connected with Bluetooth, the process numbers (namely process ID, PID for short) of the applications run by the two screens are respectively obtained, and the current application entering the sound channel is judged, so that whether the sound channel is output by a loudspeaker or output by the Bluetooth is appointed according to requirements. To the two-screen different display mechanism that accomplishes through Presentation class, connect the bluetooth with equipment, establish two player instances and play different videos, when triggering different display, set up different session numbers for two different player instances through the audio frequency session number setting interface of player class to distinguish the primary and secondary screen, thereby appoint the corresponding broadcast route according to the demand and be exported by loudspeaker or export by the bluetooth:
before describing the specific embodiment, a system framework corresponding to the method of the embodiment of the present application is described, and as shown in fig. 1, the system is roughly divided into two parts:
the Android equipment has a double-screen different display function, but only has one audio output function, namely, the audio is output by a loudspeaker;
and the Bluetooth equipment is connected with the Android equipment through Bluetooth, so that the Bluetooth equipment is used as Android equipment which only supports one sound card for playing and supplementing.

As shown in fig. 2b, the implementation process specifically includes:
step 11, the equipment is connected with Bluetooth, so that the equipment has two paths of playing ways of loudspeaker output and Bluetooth output (if the Bluetooth is not connected, sound is output from the loudspeaker by default);
step 12, in the state of double-screen simultaneous display, the main screen opens a first application (namely application A) to play a video, the main screen and the auxiliary screen both display the content of the first application, and the sound of the main screen and the sound of the auxiliary screen are both output from the Bluetooth; this is because the Android system defaults to bluetooth with the highest priority, and sound is output from bluetooth;
step 13, triggering the dual-screen different display, and setting the process number of the first application into a custom attribute, wherein the value of the custom attribute is set to be-1 in the state of the same display; the main screen returns to the desktop in the abnormal display conversion state, the auxiliary screen displays the content of the first application, and at the moment, the audio system can automatically recreate and automatically store the process number of the caller; comparing the process number with the value of the self-defined attribute, if the process number is equal to the value of the self-defined attribute, indicating that the current caller is the first application, and outputting appointed sound from Bluetooth, namely outputting auxiliary screen sound from Bluetooth;
and 14, in the abnormal display state, the main screen opens a second application (namely application B) to play the video, the process number of the second application is compared with the value of the custom attribute, if the process number is not equal to the value of the custom attribute, the current audio caller is the second application on the main screen, and the appointed sound is output from the loudspeaker.
(B) For the dual-screen different display mechanism completed by the Presentation class, as shown in fig. 3a, the implementation process of the dual-screen different sound is: connecting the equipment with Bluetooth to enable the equipment to have two paths of playing ways of loudspeaker output and Bluetooth output; creating two player instances (for example: MediaPlayer) to play different videos, respectively displaying the two videos on different screens when the abnormal display is triggered, setting different session numbers (sessionids) for the two different player instances through corresponding audio session number setting interfaces (setaudiosessionids) of the two player classes, and then distinguishing a main screen from a sub screen through the session numbers, thereby specifying whether a corresponding playing path is output by a loudspeaker or by bluetooth according to requirements. As shown in fig. 3b, the implementation process specifically includes:
step 21, the device is connected with Bluetooth, so that the device has two paths of playing ways of loudspeaker output and Bluetooth output (if the Bluetooth is not connected, sound is output from the loudspeaker by default);
step 22, in the dual-screen simultaneous display state, the main screen opens the Presentation application, instantiates a player class, namely the first player class, sets the session number ID1 through the session number setting interface of the first player class, and plays the first video (namely video a), because the dual-screen separate display is not triggered at this time, the main screen and the auxiliary screen both display the content of the first video, and the sound of the main screen and the sound of the auxiliary screen are both output from the bluetooth;
step 23, triggering double-screen different display, continuously displaying the content of the first video on the auxiliary screen, and determining the output direction of the sound by the audio system by judging the value of the Session ID; if the SessionID is equal to ID1, indicating that the current caller is from the secondary screen, designating that the sound of the first video is output from bluetooth; at this time, the Presentation application creates a player instance, i.e., a second player instance, sets the session number ID2 through the session number setting interface of the second player instance, and plays the content of the second video (i.e., video B), at this time, it is determined whether the session ID of the audio system is equal to ID2, and if so, the sound of the second video is designated to be output from the speaker.
