摘要：A device and method for audio signal uplink via an audio interface. In the device,a first pin of the audio interface is connected to an uplink audio signal generating device via a first circuit, and a second pin of the audio interface is connected to the uplink audio
sort of link
signal generating device via a second circuit, where the first circuit and the second circuit are attenuator circuits of each other. This ensures that the first pin and the second pin of the audio interface are both allowed to receive an uplink audio signal transmitted by the uplink audio signal generating device, thus implementing the effect of allowing the uplink audio signal to be transmitted in case the line sequence of the first pin and the second pin of the audio interface is unknown.
