Description
Technical field
The present invention relates to bone-conduction device technical field, shake specifically, being that a kind of ossiphone of implanted is special
Son.
Background technology
The mode that the mankind experience sound common are two kinds, first, by air vibration, sound wave through external ear, middle ear, inner ear,
Inner ear lymph, spiral organ, auditory nerve pass to cerebral cortex auditory center, and so as to generate the sense of hearing, this approach is known as gas conduction；
Another kind is osteoacusis, i.e., is passed in cerebral cortex by the skull of people, osseous labyrinth, inner ear lymph, spiral organ, auditory nerve
Pivot.
Since ossiphone occurs in nineteen twenty-three, bone conduction technology has obtained widely developing, bone conduction technology
Application have ossiphone, bone-conduction microphone, bone conduction earphone, osteoacusis mobile phone etc..Ossiphone is suitable for one
A little congenital external ear hypoplasia such as ankylotias, anotous deaf person.It is also applied for certain with outer ear disease, middle ear disease
Disease with the dense property tympanitis of change as be not suitable for wearing air conduction hearing aid or hearing loss is less than or equal to 70dBHL, with biography
The property led hearing loss but have a normal bone conduction hearing or other conductive hearing losses patient.Ossiphone uses
It is convenient, there is wide applicability, so as to be liked by many patients.
Ossiphone is there are one very important component --- bone conduction vibrator, the audio electrical signal conversion that will receive
For bone vibration signal, so as to which vibration is passed to inner ear by skull.It is distinguished according to electromechanical transformation form, bone conduction vibrator mainly has
Electromagnetic type, piezoelectric type, magnetostriction type etc. are several.Chinese patent application CN00819928.0, Chinese patent application
