Abstract
An audio interface adapter device and an audio signal receiving apparatus are provided. The audio interface adapter device comprises an audio interface having 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 audio pin is connected with the pin 3 via a first unidirectional conductive element, and connected with the pin 4 via a second unidirectional conductive element. A conductive direction of the first unidirectional conductive element is from the audio pin to the pin 3, and a conductive direction of the second unidirectional conductive element is from the audio pin to the pin 4.
