Description
Technical field
The present invention relates to listen acoustic device and listen method for acoustic, more particularly to a kind of skin to listen acoustic device and its listen method for acoustic.
Background technology
In current medical domain, acoustic, phonosensitive and its auditory nerve in sense of hearing conduction path and each in auditory system
Lesion occurs for level maincenter, causes auditory function obstacle, produces different degrees of dysacousis, is referred to as deafness.
Three classes are broadly divided into according to the difference of diseased region：Conduction deafness, nerve deafness and mixed deafness.It is born in
External auditory meatus, the deafness of the conduction voice parts of middle ear are conduction deafnesses；Betide the phonosensitive of inner ear, auditory nerve and auditory center
Deafness with neural part is sensorineural deafness；There is abnormal deafness to be Combination in conduction portion and sensory nerve part
It is deaf.
In real life, most deafness patient is according to its cause of disease using the treatment methods such as medicine, operation or logical
Wear hearing aid is crossed, implantation implanted hearing device etc. can obtain certain rehabilitation efficacy, wherein severe above phonosensitive god
Typically hearing can only be obtained using the method for implantation implanted hearing device through the deaf patient of property.Implanted hearing device includes
Vibrate overhead speaker, bone anchor formula audiphone, artificial cochlea and auditory brainstem implantation.
It is that sound is converted into mechanical oscillation to vibrate overhead speaker, and is sent to middle ear structure (such as auditory ossicular chain) or is transferred directly to
Inner ear, so as to produce the sense of hearing.Vibrating overhead speaker includes outer body and implant part, and outer body is called audio process, including
Microphone, battery and electronic installation, implant part include Inside coil, magnet, semiconductor link and floating type sensor (FMT).
Sound is converted to signal by electronic installation, and signal is transferred to Inside coil through skin, and coil reaches signal by wire
FMT, the FMT being connected with middle ear incus translate the signals into vibration direct drive incus and amplify its proper motion, ear bones vibration,
Produce the sense of hearing.Vibrate overhead speaker and be applied to moderate to the phonosensitive nerve deafness of severe.
Bone anchor formula audiphone is by strengthening osteoacusis by the extraneous incoming inner ear of sound, having bypassed external auditory meatus and middle ear.
Bone anchor formula audiphone includes three parts：Titanium alloy implant, outside bridge-set and Sound Processor Unit.By performing the operation titanium alloy
With calvarial fusion after implant implantation, acoustical vibration is transmitted to titanium alloy by outside bridge-set and is implanted into by Sound Processor Unit
Body, the vibration that vibrating device is produced finally stimulates auditory nerve by the incoming inner ear of skull, produces the sense of hearing.Bone anchor formula audiphone is fitted
For middle profound sensorineural hearing loss.
Artificial cochlea is the electric signal for converting sound into certain coding form, direct by the electrode system implanted
Auditory nerve is stimulated to recover, improve and rebuild the auditory function of deaf person.Artificial cochlea includes device outside and et al. Ke device
Two parts, device outside collection voice signal is simultaneously converted to electric signal, and electric signal passes through special digitized processing, according to specific
Speech processes strategy coding, be sent to et al. Ke device, et al. Ke device by being loaded in the wireless transmission coil after ear
Receiving coil receive after signal, decoded by decoding chip, make implantation cochlea electrod-array produce have sound characteristic
Electric current, directly stimulate auditory nerve produce the sense of hearing.Artificial cochlea is applied to have the severe of auditory nerve residual to the phonosensitive of pole severe
Nerve deafness.
Auditory brainstem implantation is the brain stem (cochlear nucleus) that stimulating electrode is put in patient, crosses cochlea and auditory nerve is directly pierced
Swash the nucleus nervi acustici group of brain stem and produce the sense of hearing.Auditory brainstem implanted device includes internal and external two parts.Internal body portion with
Artificial cochlea device is similar, including implant electrode, stimulation/receiver, and simply the shape of electrode is different with quantity.Outer body with
Artificial cochlea device is the same, including magnetic coil, directional microphone, speech processor.Auditory brainstem implantation be applied to due to
Pole severe youngster is deaf caused by auditory nerve lesion, missing or damage.
From the above, it can be seen that for phonosensitive nerve deafness more than severe, no matter using which kind of above-mentioned treatment
Method, it is necessary to be implanted into by performing the operation, there is wound, and risk is big, costly, because vivo devices need to be chronically implanted in human body,
Necessarily the performance to vivo devices has particular/special requirement so that entirely listens the cost of acoustic equipment to increase, sells expensive.
To solve above technical problem, occur in that some listen acoustic device in the prior art, China Patent Publication No. is

Outside voice signal is converted into current signal, increasing apparatus boosts common current signal, then passes through plane electrode
Skin is stimulated, the oscillator signal of electric current is transmitted to brain by skin.Technical scheme according to the invention, is carried out specific real
Apply, objective for implementation either ears deafness patient or monaural pole profound sensorineural hearing loss patient, patient can not pass through
The technical scheme obtains the sense of hearing, does not reach the technique effect described in the invention, and the program and mankind's early stage research approach are high
Spend similar, the breakthrough without essence.Early in 1790, Italian Volt inserted oneself bilateral external ear with two metal small sticks
Road, in the electric current of the indirect commensurability 50V voltages of two metal small sticks.When the head that has in a flash of connection overwhelms sense, hear therewith
The sound that a kind of similar boiling is boiled.Nineteen thirty, Wei Fu (E.G.Wever) and mine-laying (C.W.Bray) are found, from cat auditory nerve area
The electricity reaction in domain has the property similar to natural sound.At the same time, Russian scientists have studied exchange electro photoluminescence to the sense of hearing
Effect.They have found that alternating current can produce the sense of hearing, can also understand language, but their result is being only limitted to the sense of hearing just
People that is normal or having some residual hearings.
