Abstract
The utility model relates to a vibration skin phonendoscope which comprises a microphone and a audio amplifier connected with the signal output end of the microphone; the audio amplifier is further connected with a power supply and a volume adjuster for controlling the audio amplifier; the output end of the audio amplifier is connected with a rectifying device of a driving vibration motor; and the rectifying device is connected with the vibration motor. When using the phonendoscope, a totally deaf person obtains the auditory sense to the voice and the sound often met through the skin. The instrument has low power consumption and a small volume, is convenient to carry, does not need any operation when being worn and is suitable for long-term use of the deaf-mute.
Description
Technical field
This utility model relates to a kind of acoustic detecting apparatus, particularly a kind of vibration type skin phonendoscope.
Background technology
Nearly 100,000,000 hearing loss people are arranged in the world, and China just there are 2,000 ten thousand hearing loss people, how to solve these people's the problem of hearing, is a great problem in the world.What generally use at present is sonifer, but sonifer can't fundamentally solve this difficult problem.Because sonifer is to utilize mike that acoustical signal is changed into current signal and amplify, and then by speaker the acoustical signal after amplifying is sent to people's ear, promptly sonifer only plays the effect that sound amplifies.
Sonifer has following shortcoming: use speaker and mike simultaneously in (1) sonifer, if amplification is excessive, can produces mutual inductance between these two, so that can't use; (2) sonifer still will utilize people's residual hearing, so sonifer is inoperative for the more serious people of forfeiture audition.
According to the result of medical science and biological study, people's ear is felt to finish by following step for sound generating: (1) external ear, middle ear receive acoustical signal and amplify; (2) internal ear changes into electric potential signal with acoustical signal; (3) send brain to by auditory nerve again; More than in three steps any can not finishing once the step cause deafness.In fact, acoustical signal is transformed into current signal and amplification, this is the greatness invention that has just realized before human more than 100 year.Just how with this current signal can be more complete the brain of passing to then be the unsolved always problems of people, therefore also can't solve deaf person's audition problem at all.
Summary of the invention
The purpose of this utility model is to provide a kind of mode of vibration of utilizing to make human body skin obtain the vibration type skin phonendoscope of feeling for acoustical signal.
For achieving the above object, the technical solution adopted in the utility model is: comprise mike and the audio frequency amplifier that is connected with the signal output part of mike, this audio frequency amplifier, the audio frequency amplifier outfan connects the input of fairing, the outfan of fairing is connected with the input of vibrating motor again, and also is connected with power supply on audio frequency amplifier and fairing.
Also be connected with the volume adjuster of control audio frequency amplifier on the audio frequency amplifier of the present utility model.
Because this utility model utilizes mike that outside acoustical signal is changed into current signal to drive vibrating motor, vibrating motor makes skin obtain the perception of acoustical signal, do not rely on any residual hearing of human body, fundamentally solved deaf mute's audition problem.
Description of drawings
Fig. 1 is an overall structure sketch map of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are described in further detail.
Referring to Fig. 1, this utility model comprises mike 1 and the audio frequency amplifier 2 that is connected with the signal output part of mike 1, also be connected with the volume adjuster 6 of control audio frequency amplifier 2 on this audio frequency amplifier 2, the outfan of audio frequency amplifier 2 and fairing 4, the input of the outfan vibrating motor 5 of fairing 4 is connected, and also is connected with power supply 3 on audio frequency amplifier 2 and rectification 4 devices.
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, fairing 4 is used for changing audio signal into direct current signal in order to driving vibrating motor, and vibrating motor 5 is used to produce the vibration signal that skin can perception.Volume adjuster 6 is the rheostats that are installed on the audio frequency amplifier 2, is used for controlling output.But volume adjuster 6 is optional.Also can use different size resistance to substitute during concrete the making, to adapt to different user.
This utility model does not have a step when using as skin phonendoscope be to finish by the auditory system of human body, 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.This instrument is used as the method that skin phonendoscope uses, when this instrument under the competent condition of power supply, as long as vibrating motor is attached on the skin, need not any operation, just can obtain sensation for general sound.This instrument is low in energy consumption, generally is no more than 0.5W and just can uses.
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) 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; (3) behind the life-time service, because the adjusting naturally of nerve system of human body, auditory effect will be become better and better; (4) 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 needs the voice training of a period of time when using the vibration type skin phonendoscope as skin phonendoscope.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 skin phonendoscope.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.
With respect to sonifer, this utility model has following advantage when using as skin phonendoscope: (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;
With respect to cochlear implant, this utility model has following advantage when using as skin phonendoscope: (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.
