Method for realizing communication denoising and terminal

Abstract

The invention discloses a method for realizing communication denoising. The method is applied to a terminal, and the terminal is equipped with at least one auxiliary terminal. The method comprises the steps that the terminal, which is in a communication state, obtains first communication signals in the communication through a microphone of the terminal; second communication signals acquired by a microphone of each of the at least one auxiliary terminal in the communication are obtained; an auxiliary microphone of the terminal is determined according to the second communication signals acquired by the microphone of each auxiliary terminal; and voice signals of the terminal in the communication are separated from the first communication signals and the second communication signals acquired by the auxiliary microphone. Meanwhile, the invention further discloses the terminal.

Description

technical field [0001] The present invention relates to noise elimination technology, in particular to a method and a terminal for implementing noise elimination in conversation. Background technique [0002] Smart terminals such as mobile terminals, tablet computers PAD, and smart watches can all realize the voice call function. During a call, when an electronic device such as a mobile terminal receives a voice signal, it also inevitably receives external environmental noise. [0003] At present, when noise cancellation is performed on a mobile terminal during a call, two microphones MIC, the main microphone and the auxiliary microphone, are usually set for the mobile terminal; when arranging the circuit structure, the positions of the main and auxiliary microphones need to meet such distance requirements. During the call, the main microphone collects voice signals and ambient noise, and the secondary microphone collects ambient noise and a small amount of voice signals; s...

Problems solved by technology

[0004] With the development of thin and small SMART mobile terminals, the physical space reserved for the microphone is getting smaller and smaller. In theory, the following two methods can be used to achieve noise cancellation; one of them is to set only one microphone for the mobile terminal, Noise cancellation is achieved through the signal collected by the only microphone, and the effect is not obvious; the other is to set the main and auxiliary microphones for the mobile terminal on the only small-scale physical space, and this method often makes the main and auxiliary The spatial distance requirements of the microphones cannot be met, and thus the expected noise cancellation effect cannot be achieved
