The audio interface of mobile terminal comprises first a a pin, a second pin and a third pin. The first pin one of microphone is a pin and a ground pin; the second pin is the other one of the microphone pin and the ground pin; and the third pin one is of a single- channel audio output pin and a multichannel audio output pin, wherein the third pin connected is to the first pin and the second pin through a switch module. When the switch module connects the third pin to the first pin to form loop, the a impedance value of the loop matches the identification resistance of the mobile terminal; and when the switch module connects the third pin to the second pin to form a loop, the impedance value of the loop matches the identification resistance of the mobile terminal. Therefore the im­ pedance of the loop between the audio output pin of the audio interface and the ground pin matches the identification resistance of the mobile terminal, thereby ensuring that an inserted device passes the detection of the mobile terminal.
