An audio signal receiver, adapter device, and an audio signal transmission system. The audio signal adapter device is used for connecting to an audio signal transmitter device and to the audio signal receiver device, and for transmitting a signal between the audio signal transmitter device and the audio signal receiver device. The audio signal adapter device comprises: a speaker port comprising an audio signal pin, a GND pin, and a MIC pin; and an adapter-end port comprising an audio signal pin, a reference signal pin, and a ground pin. The audio signal pin of the adapter-end port and the audio signal pin of the speaker port are connected, while the reference signal pin of the adapter-end port and the GND pin of the speaker port are connected for use in transmitting to the audio signal receiver device an audio signal outputted by the audio signal transmitter device. The MIC pin of the speaker port and the ground pin of the adapter-end port are connected, while the MIC pin and the GND pin of the speaker port are used in transmitting to the audio signal transmitter device a signal outputted by the audio signal receiver device. |
