Ear back type bone conduction hearing aid device

Abstract

The invention discloses an ear back type bone conduction hearing aid device. The device comprises a shell; wherein a sound transmission part is accommodated and mounted in the shell, and a soft soundtransmission part of the sound transmission part is used for tightly pushing ears of a user from back to front and enabling a sound transmission surface of the soft sound transmission part to be tightly attached to bones behind the ears of the user; wherein one end of the shell comprises an ear hanging part and a hanging ring which is used for partially or completely surrounding auricles of a userand applying force to the sound transmission part to enable the sound transmission part to tightly push the ears. The sound transmission component is arranged behind the auricle of the user, the goodsound transmission effect and the good fixing effect are kept, most of the structure of the sound transmission component is hidden behind the ear, the invisible effect is achieved to a certain degree, the structure is attractive, and the using requirements of part of people with damaged single-ear hearing are met.

Description

technical field [0001] The invention relates to a bone conduction hearing aid, in particular to a behind-the-ear bone conduction hearing aid. Background technique [0002] With the rapid development of bone conduction technology, bone conduction hearing aids are more and more popular, especially for the elderly and other people with hearing loss or impairment, because they do not need to be inserted into the ear and avoid the discomfort caused by air pressure difference in the ear cavity. . [0003] Common bone conduction hearing aids and bone conduction earphones on the market are used to set the sound transmission parts in front of the human ear through fixing devices such as spectacle frames, headbands, hairpins, etc., and the sound transmission surface of the sound transmission parts is close to the ear. On the cheekbones on both sides of the head, the sound is converted into mechanical vibrations of different frequencies, which are transmitted through the skull, bony l...

AI Technical Summary

Problems solved by technology

Although this structure is easy to wear and fasten, almost all parts of the hearing aid device are exposed, which not only affects the aesthetic effect, but also is psychologically unacceptable to some hearing-impaired people. and miniaturization put forward improvement needs

[0004] In addition, some users only have hearing impairment in one ear, and bone conduction hearing aids in the form of glasses, headbands, hairpins, etc. on the market are all used for hearing aids in both ears. For users who only need hearing aids in one ear It is not convenient to use and affects the appearance
