A redundant network IP smart failover method and system based on a redundant computer. Each computer in any computer group comprises an IP address switching module, a network status detecting module, and a peer fault detecting module. The IP address switching module is configured to smoothly switch an IP address in the redundant network. The peer fault detecting module is configured to mutually exclusively and stably acquire operation statuses of peer computers and quickly obtain a correct redundant network IP when necessary. The network status detecting module is configured to determine statuses of local and remote networks to facilitate the IP address switching module to smartly switch the IP address. Configuring a network status detecting module and a peer fault detecting module to aid the IP address switching module to allocate IP addresses more smartly can significantly improve reliability of the redundant network and effectively reduce IP conflicts during the redundant network failover process.

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.

Embodiments of the present disclosure provide an infrared remote control apparatus and a terminal. The infrared remote control apparatus includes an audio codec chip, a transfer switch, and an infrared transmitter. The audio codec chip includes a pair of differential output pins. The infrared transmitter is connected to the differential output pins by using the transfer switch. The audio codec chip is configured to obtain an infrared remote control parameter that includes an envelope length and a carrier frequency of an infrared remote control signal. An infrared remote control signal is generated according to the envelope length and the carrier frequency. When the transfer switch sets up a connection between the infrared transmitter and the differential output pins, the audio code chip is configured to drive, by using the differential output pins, the infrared transmitter to transmit the infrared remote control signal.

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.
