Why people can hear sound, be that vibration is transmitted to ear-drum by external ear ear canal because of the vibration in air,
Pass through the auditory nerve for the vibratory drive people that ear-drum is formed.And when the middle external ear of people damages or clogs ear canal with hand, sound
Acoustical vibration can also be transmitted by the skin and bone of people, to drive the auditory nerve of people.
Osteoacusis is a kind of sound conduction mode, passes through the skull of people, temporal bone, osseous labyrinth, the transmitting of inner ear lymph, ear
Snail, auditory nerve, auditory center transmit sound wave, and here it is bone conduction technologies.Osteoacusis is to vibrate skull or temporal bone, obstructed
It crosses external ear and middle ear is transmitted directly in inner ear.Relative to traditional air transmitted side for generating sound wave by Loudspeaker diaphragm
The step of formula, osteoacusis eliminates the transmitting of many sound waves, clearly sound-reducing, and sound wave can be realized in noisy caliber
Her people will not be influenced because of spreading in air.

The characteristic of vibration, most existing bone conduction technologies all can not really solve the problems, such as that osteoacusis leaks sound, this is because the prior art
The skeleton of frequency dependence and the reality of tissue attenuation vibration signal are compensated by big volume, big vibration signal,
That is that this method is equivalent to and drinks poison to quench thirst, and user can complain that leakage sound is serious, or since it is desired that bigger power, osteoacusis are loyal
Sub-volume weight greatly increases, and causes equipment whole excessively heavy.(5) bone conduction earphone is the system of open ears, works as user
It stays in a noisy environment, can't hear the sound transmitted in earphone at all since the opening of bone conduction earphone will lead to user
Sound.
