Double-microphone denoising earphone and sound processing methods and device thereof

Abstract

The invention discloses a double-microphone denoising earphone, sound processing methods and device thereof and a computer readable memory medium. The double-microphone denoising earphone comprises two microphones set in a rear cavity of the earphone. The method comprises the steps of detecting whether a current wearing state of the earphone is standard wearing or not, wherein the standard wearingis the wearing state corresponding to the fact that a position relationship between the two microphones of the earphone and a user mouth satisfies a protection angle requirement; controlling the twomicrophones to be in a power-on state if the current wearing state of the earphone is the standard wearing, and denoising sound signals picked up by the two microphones through adoption of a double-microphone denoising method; and controlling one of the two microphones to be in the power-on state if the current wearing state of the earphone is not the standard wearing, and denoising the sound signals picked up by the microphone through adoption of a single-microphone denoising method. According to the double-microphone denoising earphone, the sound processing methods and device thereof and thecomputer readable memory medium, in a use process, when the earphone is not worn correctly, the sound signals of a user still can be picked up well, so normal communication of the user is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of microphone noise reduction, and in particular, to a dual-microphone noise reduction earphone, its sound processing method, device, and computer-readable storage medium. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the quality of life, consumer electronic products are becoming more and more popular, and the frequency of use of earphones is also increasing. When a user uses a headset to make a call in a noisy environment, the noise in the surrounding environment will affect the quality of the call, making it difficult for the other party to hear the content of the communication clearly, affecting user experience and communication efficiency. In order to solve this problem, multi-microphone uplink noise reduction has appeared, among which, the application of dual-microphone noise reduction headphones is more...

AI Technical Summary

Problems solved by technology

[0004] Since the beamforming principle has certain requirements on the consistency, position and distance of the two microphones, the headset based on dual-mic noise reduction needs to have an angle between the connection line of the two microphones and the mouth when worn within a preset range ( within the preset protection angle θ) (such as figure 1 shown), that is, the microphone can pick up the user's voice signal and remove noise well only when it is worn correctly (the position of the dual microphone and the mouth meets the design requirements). However, in actual use, the user may wear the headset. Due to the incorrect wearing method, the two microphones deviate from the range of the protection angle, which weakens the voice signal picked up by the microphone and reduces the voice quality. As a result, this part of the signal is eliminated as noise. The microphone cannot pick up the user's voice signal at all, which affects the user's normal call
