Disclosed are an audio interface adapter device and an audio signal receiving apparatus thereof. The audio interface adapter device comprises: an audio interface including pin 1, pin 2, pin 3 and pin 4, wherein the pin 1 and/or pin 2 is an audio pin/ are audio pins of the audio interface, one of the pins 3 and 4 is a microphone pin, and the other one is a ground pin. The audio pin(s) of the audio interface is/are connected with the pin 3 through a first one-way conductive device, and is/are also connected with the pin 4 through a second one-way conductive device. The conducting direction is from the audio pin(s) to the pin 3 for the first one-way conductive device, and from the audio pin(s) to the pin 4 for the second one-way conductive device. Therefore when the audio interface adapter device communicates a device connection with an audio signal which involves any type of audio interfaces, the audio signal can be normally received by the audio pin(s) (a left channel pin, and/or a right channel pin) of the audio interface. |
