Abstract

The invention provides a noise reduction earphone and a noise reduction method thereof. The noise reduction earphone comprises an earplug, a main control chip arranged in the earplug, an accommodation chamber arranged on a side wall of the earplug, and a sensor accommodated in the accommodation chamber, wherein the sensor contacts inner side skin of an ear when the earplug is put into the ear, the sensor is used for picking up a blood signal of the inner side skin of the ear and transmitting the blood signal to the main control chip, the main control chip is used for decoupling and reducing the blood signal and acquiring a voice signal corresponding to the blood signal, and the voice signal is reduced through an equipment terminal into a sound signal which is emitted. The noise reduction earphone is advantaged in that the accurate transmission of the voice signal under the strong noise environment is guaranteed, and the noise reduction effect is realized.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to an uplink noise reduction earphone and an uplink noise reduction method thereof. Background technique [0002] At present, earphones with an uplink noise reduction function are mainly realized by using an air conduction scheme, a bone conduction scheme, or a scheme combining air conduction and bone conduction. Among them, air conduction solutions mostly use dual microphones or multi-microphone arrays for uplink noise reduction, which can achieve a certain degree of uniformity of background noise, thereby achieving the purpose of enhancing voice signals and improving call quality. The bone conduction solution or the combination of air conduction and bone conduction uses a bone conduction microphone that can pick up human body vibrations to pick up voice signals, which is more effective in suppressing ambient noise. [0003] However, in practical applications, t...
