Zusammenfassung:	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.
