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

Embodiment 1

[0012] Example 1: refer to the attached figure 1 . A bionic behind-the-ear hearing aid includes a behind-the-ear hearing aid 1, the back of the behind-the-ear hearing aid shell is a bionic surface 2 of the back of the human ear, and the bionic surface can form a complete fit with the back groove surface of the human body.

Embodiment 2

[0013] Example 2: refer to the attached figure 1 and 2 . On the basis of Example 1, a method for manufacturing a bionic back-of-the-ear hearing aid, (1) take an ear impression: use a proofing paste to take an ear impression on the back of the ear; (2) cut the ear impression: keep the ear of the ear-like auricle surface The back remains unchanged, cut the top of the ear impression perpendicular to the back of the ear along the top concave point on the back of the ear, and take the ear impression, the length of which is greater than 8mm; (3) Grinding the ear impression: smooth all cut surfaces; (4) Waxing: will be processed well A layer of wax is hung on the ear impression mold; (5) Casting the negative mold: put the waxed impression into a suitable mold ring and dip a little wax at the bottom of the ear impression to fix it, heat the agar to a liquid state, and wait for the agar to cool. When the temperature reaches about 50 ℃, pour it into the ring to submerge the whole ear ...

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 type behind-the-ear hearing aid which can be completely matched with the curved surface of the back of the human ear and a manufacturing method thereof, and belongs to the field of manufacturing technology of hearing aids. Background technique [0002] CN101895808A, name "in-the-ear talk-behind-the-ear hearing aid", including a horn on which an air conduit is connected through a hose, and the air conduit is placed close to the middle ear eustachian tube; the hearing aid of the present invention solves the problem of signal transmission to For the problem of signal attenuation in the eardrum, under the premise of ensuring the user's wearing comfort, the traditional method of improving the quality of the signal to improve the user's sound reception is changed to changing the structure and increasing the air pipe to make the sound signal. It is directly transmitted from the external auditory canal to the eardrum, so that ...
