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.

Noise reduction operation control method for headset and audio processor in terminal device

A headset jack includes a side wall, a bottom part, a clamping component on the side wall, a first detection end at the bottom part, a second detection end on the side wall or at the bottom part, and a membrane switch electrically connected to the second detection end. The clamping component is configured to clamp a headset plug when the headset plug is inserted into the headset jack. When the headset plug is not inserted in position, the membrane switch is electrically isolated from the first detection end. The membrane switch is configured to generate elastic deformation under a pressure of the headset plug when the headset plug is inserted in position and be electrically connected to the first detection end.
