Problems solved by technology

Hearing aids have the following disadvantages: (1) The speaker and microphone are used in the hearing aid at the same time. If the amplification factor is too large, there will be mutual inductance between the two, so that it cannot be used; (2) The hearing aid still uses the residual hearing of the person, so the hearing aid Does not work for people with severe hearing loss
However, how to transmit this current signal to the brain relatively completely is a problem that people have not been able to solve, so it is impossible to fundamentally solve the hearing problems of deaf people.

Embodiment Construction

[0007] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0008] Referring to accompanying drawing, the present invention comprises microphone 1 and the audio amplifier 2 that is connected with the signal output end of microphone 1, audio amplifier 2 is also connected with power supply 3 by volume adjuster 6, and the output end of audio amplifier 2 passes booster 4 It is connected with the input end of the plane electrode 5 . Among them, the microphone 1 is used to convert the external sound signal into a current pulse signal, the audio amplifier 2 is used to amplify the audio signal, the power supply 3 is used to provide power for the audio amplifier 2, and the common planar electrode 5 is used to pass the current oscillating signal through the skin to the brain. Wherein the sound signal step-up device 4 used a low-frequency transformer. Microphone 1 acquires the ...

Abstract

Disclosed is a pressure variation type skin listening apparatus aimed at solving the hearing disorders for the totally deaf, comprises a microphone and an audio-frequency amplifier connected with the signal output terminal of the microphone, it also includes a power supply connected with the audio-frequency amplifier, the output end of the audio-frequency amplifier is connected with the input end of the plane electrode through a pressure boosting device. The listening apparatus can be worn by the deaf to obtain the audition to voices and sounds they are normally exposed to.

Description

technical field [0001] The invention relates to a hearing device, in particular to a pressure-changing skin hearing device. Background technique [0002] There are nearly 100 million hearing disabled people in the world, and there are 20 million hearing disabled people in my country. How to solve the listening and speaking problems of these people is a major problem in the world. Hearing aids are commonly used at present, but hearing aids cannot fundamentally solve this problem. Since the hearing aid uses the microphone to convert the sound signal into a current signal and amplifies it, and then transmits the amplified sound signal to the human ear through the speaker, that is, the hearing aid only plays the role of sound amplification. Hearing aids have the following disadvantages: (1) The speaker and microphone are used in the hearing aid at the same time. If the amplification factor is too large, there will be mutual inductance between the two, so that it cannot be used;...
