Abstract

The invention relates to the technical field of noise reduction, and discloses a mobile terminal and a method for reducing audio noise. In the present invention, the mobile terminal includes: an audio power amplifier, a loudspeaker, a microphone, and a codec chip; wherein the codec chip collects the first audio signal, and the microphone collects the second audio signal and outputs it to the codec chip; The first noise signal and the second noise signal are extracted from the first audio signal and the second audio signal, and output to the audio power amplifier; the audio power amplifier performs compensation processing on the first audio signal according to the first noise signal and the second noise signal. The embodiments of the present invention can effectively suppress the noise on the audio line of the mobile terminal and the audio noise played by the speaker, improve the sound quality of the output audio and the subjective experience of the human ear, and further improve the user experience.

Description

technical field [0001] The invention relates to the technical field of noise reduction, in particular to a mobile terminal and a method for reducing audio noise. Background technique [0002] Because mobile terminals bring great convenience to people's lives, playing audio using mobile terminals has also become one of the main demands of users. However, due to the existence of noise, the sound quality of the audio playback is far from meeting the needs of the user, resulting in poor user experience. Contents of the invention [0003] The problem to be solved by the present invention is to provide a mobile terminal and its method for reducing audio noise, so that the mobile terminal can reduce the noise of the played audio, improve the sound quality of the output audio and the subjective experience of the human ear, and further improve user experience. [0004] In order to solve the above technical problems, the embodiment of the present invention provides a method for red...
