Electronic device, audio processing circuit thereof, and output method of audio signal

The present invention provides an electronic device, an audio processing circuit thereof, and an output method of an audio signal. The audio processing circuit comprises a branching unit for receiving an analog audio signal to be processed and outputting the analog audio signal to a first amplifying circuit and/or second amplifying circuit, the first amplifying circuit for carrying out power amplification processing on the received analog audio signal according to a first audio signal output standard and outputting the signal to a gating unit, the second amplifying circuit for carrying out power amplification processing on the received analog audio signal according to a second audio signal output standard and outputting the signal to the gating unit, and the gating unit used for sending the analog audio signal from the first amplifying circuit or the second amplifying circuit to a same output interface for outputting. According to the invention, the outputting of the audio signals with different driving standards by one output interface is realized, the audio output interface function of the electronic device is expanded, and the device space and cost are saved.
