Bionic behind-the-ear hearing aids and manufacturing method thereof

Abstract

The invention relates to bionic behind-the-ear (BTE) hearing aids which can be fully matched with the cambered surfaces of the ear backs of a human body, and a manufacturing method thereof. The bionic BTE hearing aids comprise BTE hearing aids, wherein the back faces of BTE hearing aids shells are bionic surfaces of the ear backs of the human body. The bionic BTE hearing aids have the advantages that: firstly, the aim of fully matching the back faces of the BTE hearing aids with the ear back surfaces of the human body is fulfilled, so that the BTE hearing aids are prevented from shaking along with the body movement and head shake of a wearer in walking and talking processes, a non-audio signal is prevented from being amplified and introduced into ears, hearing aiding function of high-sensitivity and high-fidelity BTE hearing aids is ensured and hearing aiding effect is doubled; and secondly, the BTE hearing aids are fully embedded into the back faces of the ears of the human body, so that the BTE hearing aids are worn comfortably and concealed well.

Description

technical field [0001] The invention relates to a bionic back-of-the-ear hearing aid capable of completely conforming to the curved surface of the back of the ear of a human body and a manufacturing method thereof, and belongs to the field of manufacturing technology of hearing aids. Background technique [0002] CN101895808A, the name "back-of-the-ear hearing aid for speaking in the ear", includes a horn, and an air duct is connected to the horn through a flexible pipe, and the air duct is placed close to the Eustachian tube of the middle ear; the hearing aid of the present invention solves the problem of signal transmission to For the problem of signal attenuation in the eardrum, on the premise of ensuring the user's wearing comfort, the traditional way of improving the quality of the signal to improve the user's sound reception is changed to changing the structure and increasing the air duct to make the sound signal It is directly transmitted from the external auditory ca...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the above-mentioned background technology: hearing aids are very sensitive amplifiers, which can effectively amplify tiny vibrations, and then transmit them to the ear canal of the human body through the horn, so that the hearing-impaired can hear the sound

However, in the background technology, the back curvature of the BTE hearing aid shell does not match the curvature of the back of the ear of each hearing aid user, so shaking is inevitable, and the noise generated by the shaking is directly amplified by the hearing aid and transmitted to the ear of the human body. , not only affects the hearing effect of hearing aid users, but also causes the resolution of hearing aids to decrease
