Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] In view of the problem of unstable uplink noise reduction performance in the aforementioned existing earphone uplink noise reduction methods, the present invention reuses the noise reduction microphone in the left or right earpiece of the earphone as the first uplink noise reduction microphone and the call microphone as the second uplink noise reduction microphone. Two uplink noise reduction microphones, and then compare the voice signal picked up by the second uplink noise reduction microphone with a preset threshold, the preset threshold being the energy value of the voice signal picked up by the second uplink noise reduction microphone in advance or Sensitivity value; when the voice signal picked up by the second uplink noise reduction microphone is less than the preset threshold, the first uplink noise reduction microphone and the sec...

Abstract

Provided is an earphone uplink denoising method. The method comprises: multiplexing a denoising microphone in a left or right receiver of an earphone as a first uplink denoising microphone, and taking a call microphone as a second uplink denoising microphone; acquiring a voice signal picked up by the second uplink denoising microphone, and comparing the voice signal with a pre-set threshold value, wherein the pre-set threshold value is a pre-set energy value or a sensitivity value of the voice signal picked up by the second uplink denoising microphone; if the voice signal is less than the pre-set threshold value, using the first uplink denoising microphone and the second uplink denoising microphone to perform noise elimination on the voice signal; otherwise, using the second uplink denoising microphone to perform noise elimination on the voice signal. By means of the present invention, the problem that the earphone uplink denoising performance fluctuates because the position of a cell microphone is not fixed can be avoided, such that the voice quality of a call is improved.

Description

Technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to an uplink noise reduction method for earphones. Background technique [0002] With the widespread application of high-quality smart phones, pads and other portable electronic products, people have higher and higher requirements for the acoustic parameters of earphones that can be used with them. With the introduction of TypeC and Lightning interfaces, earphones gradually switch to digital mode, and earphones with ANC (Active Noise Control, Active Noise Control) function can be implemented on digital earphones. [0003] In the current ANC headsets, there are two main ways to realize the noise reduction function. One is to realize the uplink noise reduction function through the call microphone; the other is to realize the noise reduction function by multiplexing the microphones set in the earpieces on the left and right sides. Uplink noise reduction. Although the meth...
