An earphone, corresponding audio source device and control method

Abstract

A wired earphone, the earphone includes an audio decoding unit, used to decode the audio signal data stream; an audio processing unit, used to perform sound effect processing on the audio signal; a power distribution unit, at least used for the audio decoding unit Or / distribute power with the audio processing unit; the audio source device interface unit is configured to receive the audio signal and power from the audio source device in a wired connection. A method for controlling a sound source device, the method comprising: connecting the sound source device to an earphone through a wired interface, and the sound source device according to the functional characteristic parameters of an audio decoding unit or / and an audio effect processing unit read from the earphone , to selectively output the digital audio signal after audio decoding processing or / and sound effect processing. After adopting the above method, the audio source device and the earphone can not only be unified in interface, but also can be unified in function. The same audio source device can adapt to earphones with different performances, support each other in function, reasonably expand, support more choices, and Keep the best output.
