发明名称 DUAL-MICROPHONE EARPHONE AND NOISE REDUCTION PROCESSING METHOD FOR AUDIO SIGNAL IN CALL
摘要 Disclosed are an earphone, a terminal, and an audio signal processing method based on the earphone and the terminal. The audio signal processing method comprises: a first microphone of an earphone obtaining, during a call, a first audio signal comprising call voice and background noise, and a second microphone of the earphone obtaining, during the call, a second audio signal comprising the background noise; and transmitting the first audio signal and the second audio signal to a noise reduction chip built in a terminal by means of an external plug of the earphone, so that the noise reduction chip performs noise reduction processing on the first audio signal according to the second audio signal. By means of the scheme, the present invention enables a terminal to perform, by using a noise reduction chip built in the terminal, noise reduction processing on an audio signal obtained by an earphone when the earphone is used for a call, and accordingly, costs are reduced while call quality is improved, thereby facilitating popularization.
