Pressure swing type skin listener

Abstract

The invention relates to human biological, electronic and acoustic technologies, in particular to a pressure-transforming dermal hearing device. The device mainly solves the hearing impairment of the deaf. It includes a microphone and an audio amplifier connected with a signal output end of the microphone. It also includes a power supply connected with the audio amplifier, and the output end of the audio amplifier is connected with the input end of the plane electrode through a boosting device. People who are totally deaf can hear speech and commonly encountered sounds as long as they wear a hearing aid. The instrument has low power consumption, small size, and is easy to carry. It does not require any surgery when wearing it, and is suitable for long-term use by deaf people.

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;...

AI Technical Summary

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.
