Abstract:
1. An audio interface adapter device, comprising an audio interface, wherein the audio interface comprises a pin 1, a pin 2, a pin 3 and a pin 4, the pin 1 and/or the pin 2 is used as an audio pin of the audio interface; one of the pin 3 and the pin 4 is used as a microphone pin, and the other one of the pin 3 and the pin 4 is used as a ground pin; the pin 1 is connected with the pin 3 via a first signal processing unit and via a first unidirectional conductive element in sequence, and connected with the pin 4 via the first signal processing unit and via a second unidirectional conductive element in sequence; and/or the pin 2 is connected with the pin 3 via a second signal processing unit and via the first unidirectional conductive element in sequence, and connected with the pin 4 via the second signal processing unit and via the second unidirectional conductive element in sequence; a conductive direction of the first unidirectional conductive element is from the audio pin to the pin 3; a conductive direction of the second unidirectional conductive element is from the audio pin to the pin 4.
