Abstract

The invention discloses a multi-microphone denoising headphone and method. One specific embodiment of the headphone comprises a headband and headphone bodies connected with two ends of the headband.The headphone also comprises a microprocessor and at least three microphones set on the outer side face of the headphone bodies. The microprocessor selects the microphone nearest to a target sound source as a master microphone through comparison of sound signals picked up by the microphone, selects the microphone farthest from the master microphone as an auxiliary microphone according to preset relative locations of the microphones, takes a first sound signal picked up by the master microphone and a second sound signal picked up by the auxiliary microphone as denoising algorithm input and performs a denoising algorithm to realize denoising. According to the embodiment, under the condition that a user wears the headphone abnormally, the denoising performance is ensured.

Description

technical field [0001] The invention relates to the field of earphone noise reduction. More specifically, it relates to a multi-mic noise reduction earphone and its method. Background technique [0002] Existing earphones, especially headsets, generally have an uplink noise reduction function. The uplink noise reduction function is mainly to eliminate the local environmental noise as much as possible when the user uses the earphone to make a call, so as to ensure that the voice signal is transmitted as clearly as possible to the peer to ensure call quality. [0003] At present, the upstream noise reduction of the headset is mainly realized by setting up a single microphone or dual microphones, and working with a noise reduction algorithm. Among them, the general principle of dual microphones combined with the noise reduction algorithm is as follows: among the dual microphones, the one close to the target sound source—the user’s mouth is used as the main microphone, and the...
