Bone conduction microphone and handset

Abstract

The invention provides a bone conduction microphone which comprises a vibration collector, a pressure sensor and a signal processor; the vibration collector comprises a signal collection part and a signal transmission part; the signal transmission part is in contact with the pressure sensor; and the signal transmission part can transmit signals collected by the signal collection part to the pressure sensor. The bone conduction microphone has the beneficial effects that: as sound signals can be directly transmitted to the signal sensor through the signal transmission part, problems such as signal lag and signal inaccuracy caused by a traditional airbag which transmits the sound signals through air are avoided; signals can be collected more precisely and signal error caused by air leakage of a vibration cavity can be reduced or removed; the bone conduction microphone is more beneficial to signal collection and data analysis, the data are more precise, calculation of the collected data can be finished by using fewer processor resources, and the data error and power consumption are reduced; and collection of sound source signals is realized more precisely.

Description

technical field [0001] The invention relates to a bone conduction microphone and an earphone thereof. Background technique [0002] Bone conduction is a sound conduction method, which converts sound into mechanical vibrations of different frequencies, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph fluid transmission, screw, auditory nerve, and auditory center. Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction saves many steps of sound wave transmission, and can achieve clear sound reproduction in a noisy environment, and the sound waves will not affect others due to diffusion in the air . Bone conduction technology is divided into bone conduction speaker technology and bone conduction microphone technology: [0003] (1) Bone conduction speaker technology is used to receive the voice, and the voice is heard when the voice is received. Air conduction speakers convert electri...

AI Technical Summary

Problems solved by technology

[0007] First, the vibrating element in the prior art is usually an independent element, which is usually installed in a clamping way with the housing, which will easily cause air leakage in the vibration chamber and cannot directly transmit the vibration of the sound source

[0008] Second, since the vibration components are usually flat surfaces, they cannot fully perceive the vibration of the sound source, and it is easy to miss the signal, resulting in the sound not being completely transmitted out.

[0009] Third, the sensors in the prior art are usually in a planar shape, which is unfavorable for sensing the vibration of the sound source

[0010] Fourth, the direct transmission between the vibration element and the sensor is usually indirect, which is not conducive to the transmission of signals
