Summary of the invention
The object of the present invention is to provide a kind ofly, utilize the organon auditus of electronics and acoustic technique imitation human body, for the transformed skin acoustic detecting apparatus of deaf mute use according to biological audition principle.
For achieving the above object, the technical solution used in the present invention is: comprise mike and the audio frequency amplifier that is connected with the signal output part of mike, also comprise the power supply that is connected with audio frequency amplifier, be characterized in, the outfan of audio frequency amplifier is connected with the input of increasing apparatus, and the outfan of increasing apparatus is connected with the input of plane electrode again; Can also be in series with volume adjuster between audio frequency amplifier and the power supply.
Because the present invention utilizes mike that outside acoustical signal is changed into current signal, the equipment that boosts boosts common current signal, then by the plane electrode chafe, the oscillator signal of electric current is passed to brain by skin, do not rely on any residual hearing of human body, fundamentally solved deaf mute's audition problem.
Description of drawings
Accompanying drawing is an overall structure sketch map of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present invention and operation principle are described in further detail.
Referring to accompanying drawing, the audio frequency amplifier 2 that the present invention includes mike 1 and be connected with the signal output part of mike 1, audio frequency amplifier 2 also is connected with power supply 3 by volume adjuster 6, and the outfan of audio frequency amplifier 2 is connected by the input of increasing apparatus 4 with plane electrode 5.Wherein mike 1 is used for the external voice signal is converted into current pulse signal, audio frequency amplifier 2 is used for audio signal is amplified, power supply 3 is used to audio frequency amplifier 2 that power supply is provided, and common planar electrode 5 is used for the oscillator signal of electric current is passed to brain by skin.And acoustical signal increasing apparatus 4 uses wherein is the low frequency transformator.Mike 1 obtains the external sound signal, and acoustical signal is converted into current signal is input to audio frequency amplifier 2, the acoustic current-meter signal that audio frequency amplifier 2 is sent mike 1 here amplifies, at this moment the voltage of the power supply that provides 3 generally is provided alternating voltage, usually below 0.2V, increasing apparatus 4 is converted into the acoustic current-meter signal of alternating voltage with the acoustic current-meter signal of audio frequency amplifier 2 outputs, and boosts to more than the 5V, to overcome the resistance of skin.Power supply 3 provides power supply for audio frequency amplifier 2 or increasing apparatus 4, minimumly just can move at 1.2V, the acoustic current-meter signal stimulus skin that plane electrode 5 utilizes increasing apparatus 4 to provide, volume adjuster 6 is the rheostats between power supply 3 and the audio frequency amplifier 2, is used for controlling the output of power supply 3.But volume adjuster 6 is optional.Also can use different size resistance to substitute during concrete the making, to adapt to different user.
It is to finish by the auditory system of human body that the present invention does not have a step, that is to say that it does not rely on any residual hearing of human body, so it has fundamentally solved deaf mute's audition problem.Use the method for transformed skin acoustic detecting apparatus to be, under this instrument is being powered competent condition,, just can obtain audition for general sound, particularly voice as long as electrode paste near the skin the ear, need not any operation.This instrument is low in energy consumption, generally is no more than 0.5W and just can uses.Mike 1 in this instrument can be filled in earhole, can be placed on Audio Processing part and power supply in the pocket so that carry.
Points for attention during use: (1) needs the stage of one section adaptation, because they never felt sound, sound is a kind of new signals for them for the serious people of hearing disability; (2) life-time service may cause electrode contact position skin discomfort, is preferably in and stops using in bed evening, so that allow the skin of electrode contact position be restored; (3) will be adjusted to suitable volume, volume is too little can not to cause audition, and volume is too big if run into loudly then electrode meeting twinge skin; (4) behind the life-time service, because the adjusting naturally of nerve system of human body, auditory effect will be become better and better; (5) if taking energy discrimination people's voice then needed after 1 year, need considerable time because will form the language trained reflex.According to Pavlov's theory, the people is to form setting up in the process of language trained reflex for the understanding of language.So the deaf mute uses transformed skin acoustic detecting apparatus to need the training of a period of time later on.But this training does not need special environment, but participates in people's normal activity, makes own to being reflected by the obtained voice signal formation condition of transformed skin acoustic detecting apparatus.Reflecting the needed time for the voice signal formation condition can vary with each individual, in general age people little and that have a high IQ adapt to faster.
When wearing transformed skin acoustic detecting apparatus its mike 1 being placed in the earhole is proper position, and the contact position that is used for the plane electrode 5 of chafe generally is near the skin of the smoother ear, is proper position below the ear-lobe.The power that transformed skin acoustic detecting apparatus consumed is bigger than sonifer, can be packaged together power supply 3 and audio frequency amplifier 2 and increasing apparatus 4 to connect with long lead with other device, so that power supply etc. is contained in the pocket of clothes.Under the condition that processing technology allows, can also be produced on increasing apparatus 4 with electrode 5.
The deaf mute can respectively be with a transformed skin acoustic detecting apparatus on two ears.
With respect to sonifer, the present invention has following advantage: (1) receives any residual hearing that sound does not rely on human body, is applicable to that the very serious people of hearing loss uses; (2) remolding sensitivity is higher, with the range of audibility basically identical of people's ear, so can obtain audition for voice and the sound that often runs into; Can not go out the such noise of phenomenon sonifer when (3) increasing volume; (4) mike can be filled in earhole, can not resemble that mutual inductance causes and can't use because mike is from speaker is too near the sonifer;
With respect to cochlear implant, the present invention has following advantage: (1) receives any residual hearing that sound does not rely on human body, and the auditory nerve blemisher still can use; (2) remolding sensitivity is higher, with the range of audibility basically identical of people's ear; (3) without any need for operation, side effect does not almost have.
