9. a kind of mobile terminal, it is characterised in that include：
Detection module, for detecting the equivalent distances between the user/mobile terminal and the audio amplifier, or detects the movement
The signal strength signal intensity of the audio amplifier that terminal is received；
Volume acquisition module, it is described for obtaining the target sound value of the corresponding audio amplifier of the equivalent distances/signal strength signal intensity
Equivalent distances are the equivalent distances of the user/between mobile terminal and audio amplifier, the signal strength signal intensity be the user/movement eventually
The signal strength signal intensity of the audio amplifier that termination is received；
Volume setup module, for the target sound value to be sent to into the audio amplifier, makes the audio amplifier with the target volume
Value is played, so that the volume that the audio amplifier is played keeps stable relative to the user/mobile terminal.
10. a kind of audio amplifier, it is characterised in that include：
Detection module, for detecting the equivalent distances of the user/between mobile terminal and audio amplifier, or detects the mobile terminal
The signal strength signal intensity of the audio amplifier for receiving；
Volume acquisition module, it is described for obtaining the target sound value of the corresponding audio amplifier of the equivalent distances/signal strength signal intensity
Equivalent distances are the equivalent distances between the mobile terminal and audio amplifier, and the signal strength signal intensity is that the mobile terminal is received
The signal strength signal intensity of the audio amplifier；
Volume setup module, for target sound value broadcasting, so that the volume that the audio amplifier is played is relative to described
User/mobile terminal keeps stable.
