Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] figure 1 It shows the main flowchart of the noise reduction method described in the embodiment of the present invention.

[0024] see figure 1 As shown, the noise reduction method may include the following steps:

[0025] S101: Judging whether the ambient noise is greater than a predetermined threshold, and obtaining a judging result;

[0026] S103: When the judgment result is that the ambient noise is greater than or equal to the predetermined threshold, turn on the noise reduction algorithm of the dual microphones to perform noise reduction;

[0027] S105: When the judging result is that the surrounding environment noise is less than the predetermined threshold, turn off the noise reduction algorithm.

[0028] In the above technical sol...

Abstract

The invention provides a noise reduction method, a device and a mobile terminal. The method and the device are applied to the mobile terminal with double microphones. The noise reduction method comprises the steps that whether the noise of the ambient environment is greater than a predetermined threshold is judged, and a judgment result is acquired; when the judgment result is that the noise of the ambient environment is greater than or equal to the predetermined threshold, a noise reduction algorithm of the double microphones is switched on for noise reduction; when the judgment result is that the noise of the ambient environment is less than the predetermined threshold, the noise reduction algorithm is switched off. According to the technical scheme of the invention, the problem of use inconvenience, which is caused by the fact that the noise reduction algorithm of the double microphones needs manual setting before a conversation, can be effectively solved.

Description

technical field [0001] The present invention relates to the field of communication products, and more specifically, to a noise reduction method, device and mobile terminal. Background technique [0002] Most of the currently used mobile terminals are equipped with dual microphones and have dual-microphone noise reduction functions, while handheld terminals with dual-microphone noise reduction functions will enable the noise reduction function by default when incoming or outgoing calls are made. The sound quality of the call is damaged to a certain extent, and it is easy to cause slight distortion of the sound. The usual solution is to preset the noise reduction function on or off on the handheld terminal before the call, that is, to manually switch the noise reduction on or off, but this method requires the user to manually set it before the call, which is not smart enough. [0003] Therefore, there is a problem in the prior art that the dual-microphone noise reduction algo...
