Abstract
A noise reduction operation control method for a headset and an audio processor in a terminal device, where a pin of a universal serial bus (USB) Type-C interface is multiplexed. During implementation of the solutions in this application, a switch circuit corresponding to the pin of the USB Type-C interface is switched to ensure that a normal function of the pin of the USB Type-C interface is not affected. In addition, a digital microphone (DMIC) processor in a terminal device and a noise reduction microphone in a headset are coupled using the pin of the USB Type-C interface such that a noise reduction signal from the noise reduction microphone in the headset is received using the DMIC processor in the terminal device, thereby implementing noise reduction processing for the headset using the terminal device.
