Description
Technical field
The present invention relates to a kind of bone-conduction microphone and its earphone.
Background technology
Osteoacusis is a kind of sound conduction mode, i.e., sound is converted into the mechanical oscillation of different frequency, passes through the cranium of people
Bone, osseous labyrinth, inner ear lymph transmission, spiral organ, auditory nerve, auditory center transmit sound wave.Produced with respect to vibrating diaphragm
The classical sound conduction mode of sound wave, osteoacusis eliminates the step of many sound waves are transmitted, and can realize in a noisy environment clear
Clear sound-reducing, and sound wave also will not have influence on other people because of spreading in atmosphere.Bone conduction technology is divided into osteoacusis
Loudspeaker techniques and bone-conduction microphone technology：
（1）Bone-conduction speaker technology is called to listen to sound for called.Conductance loudspeaker is that electric signal is converted into sound wave
（Vibration signal）Reach auditory nerve.And bone-conduction speaker is then the sound wave of electric signal conversion（Vibration signal）Directly pass through bone
Reach auditory nerve.Sound wave（Vibration signal）Transfer Medium it is different.
（2）Bone-conduction microphone technology is used to send words, send words to collect sound.Conductance send words to be that sound wave is reached by air
Microphone, and bone-conduction microphone words are then directly transmitted by bone.
Osteoacusis has portable and squash type two ways, and the two collaboration can stimulate spiral organ to cause the sense of hearing, its specific biography
The approach of leading is：" sound wave-skull-osseous labyrinth-inner ear lymph-spiral organ-auditory nerve-cerebral cortex auditory center ".Usual people
Also and be not required to go to experience sound using the skull of oneself, still, when the lesion of external ear and middle ear makes sound wave transmission be obstructed, then
Hearing can be made up using osteoacusis.Such as osteoacusis formula audiphone, osteoacusis formula earphone, are exactly experienced using osteoacusis
Sound.The earphone manufactured using these bone conduction technologies, referred to as bone conduction earphone, also referred to as osophone, bony ear
Machine, bone pass earphone and bone sensing earphone.
Existing bone passes microphone and there is following defect：
Firstth, vibrating elements of the prior art is generally all an independent element, and it generally uses the peace of clamping with housing
Dress mode, is so easily caused vibration cavity gas leakage, it is impossible to directly transmit the vibration of sound source.
Secondth, because vibrating elements is generally all straight surface, it is impossible to fully perceive the vibration of sound source, easily miss
Signal, causes sound fully can not really pass.
3rd, sensor of the prior art is typically flat shape, and the vibration for perception sound source is unfavorable.
4th, vibrating elements and sensor are all generally directly indirect transfers, and the transmission for signal is unfavorable.
The invention of application number 201410292494.5 is related to anti-riot, technical field of fire control, discloses osteoacusis radio communication
