Abstract

The present invention discloses a denoising method, device and system. The method is applied to an earphone, the earphone is equipped with a microphone and an earphone loudspeaker, and the microphone is used for acquiring the sound information of the users. The method comprises the steps of using the microphone to acquire the current environmental noise information when the situation that there is currently existed the to-be-played audio information or the audio information is being played currently, is determined; according to the environmental noise information obtaining the anti-noise information; superposing the anti-noise information and the audio information to obtain the superposed audio information; playing the superposed audio information via the earphone loudspeaker. According to the technical scheme, when the to-be-played audio information is detected or the audio information is being played, the microphone does not acquire the sound of the users at the moment, so that the microphone can acquire the environmental noise, then the anti-noise information is obtained according to the environmental noise, and further the noise is reduced according to the anti-noise information, and accordingly, a scheme of arranging the microphone on the earphone to denoise is realized, the structure of the earphone is simplified, and the manufacturing cost of the earphone is reduced.

Description

technical field [0001] The present disclosure relates to the technical field of information processing, and in particular to a noise reduction method, device and system. Background technique [0002] Many users like to listen to music while running or reading and enjoy the effect of music surround. However, due to the existence of environmental noise, especially some persistent noise, it is easy to affect the user's listening experience, so noise-canceling headphones came into being. [0003] The noise-canceling earphones in the related art are usually provided with two microphones. In addition to the microphone used to collect the user's voice when the user makes a call or sends a voice message, there is also another microphone used to collect ambient noise. After the ambient noise is collected by the microphone, the processor can simulate anti-noise information according to the environmental noise, and then superimpose the anti-noise information and audio information and ...
