Noise reduction headset

Abstract

The invention discloses a noise reduction headset. The noise reduction headset comprises a left earphone, a right earphone and a noise reduction unit; each of the left earphone and the right earphoneincludes a headset housing, a main microphone and an auxiliary microphone located outside a human ear canal, and an internal microphone located inside the human ear canal; the main microphones and theauxiliary microphones pick up a first voice signal spread via air; and the noise reduction unit performs noise reduction on the first voice signal and then performs superimposition on the first voicesignal and a second voice signal picked up by the internal microphones and transferred by a human body to generate a to-be-sent signal. According to the noise reduction headset provided by the invention, by performing noise reduction processing on the first voice signal picked up by the main microphones and the auxiliary microphones and then superimposing the first voice signal with the low-frequency second voice signal picked up by the internal microphones, a high-quality voice signal is obtained.

Description

technical field [0001] The invention relates to the technical field of earphones. More specifically, it relates to a noise reduction earphone. Background technique [0002] At present, wireless headsets generally have an uplink noise reduction function, and uplink noise reduction means call noise reduction. When people make a call outdoors or in a noisy environment, if the noise is relatively large, the user's voice will be covered, making the person on the other end of the call unable to hear the user's voice clearly. In order to solve this problem, a noise reduction technology has emerged Earphone, the microphone of the earphone receives the voice signal and the noise signal of the surrounding environment at the same time, the above two signals are transmitted to the noise reduction circuit, and the noise reduction algorithm is used to filter out the environmental noise signal to ensure that the other party can still hear the clear voice signal. However, it is often diff...

AI Technical Summary

Problems solved by technology

However, it is often difficult to achieve a good noise reduction effect when the noise on one side of the earphone is relatively large and the noise on the other side is relatively small.

For example, when using this kind of noise-canceling headset to make a call in windy weather outdoors, the headset microphone on the windward side picks up a lot of wind noise, while the wind noise on the windward side is relatively small, resulting in poor noise-canceling effect of the headset.
