Background technique

The basic principle of existing hearing aids is to receive external sound through a microphone, and then amplify the sound signal through an amplifier; the amplified sound is output through a combination of an earphone (earphone) and an eardrum (ear-mold). to the eardrum to achieve the effect of hearing aid. Among them, the amplifier can provide hearing-impaired people to adjust the volume.

However, for the hearing-impaired, the purpose of using a hearing aid is to amplify the conversation sound, and the frequency spectrum of certain noises in the environment and the spectrum of the conversation sound are repeated; in other words, the existing hearing aids also amplify the conversation sound The noise in the environment is amplified, making it difficult for the hearing-impaired to recognize the content of the conversation; at the same time, the hearing-impaired is more likely to be disturbed by the noise when listening to the conversation sound, which may cause hearing discomfort.

In addition, the existing hearing aids have a certain volume in design, and in order to consider the effect of hearing aids, the hearing aids must partially extend into the ear canal of the human body and occupy part of the ear canal space to achieve the purpose of hearing aids; however, there are The eardrum of the hearing aid is designed to completely cover the ear canal; when the hearing-impaired wears the hearing aid, it will no longer be able to be used with the earphone, which has the disadvantage of being inconvenient to use.

To sum up, due to the limitations of hearing aids, the hearing-impaired cannot use earphones, and the existing hearing aids cannot filter out external noise and cannot provide better sound quality, so the disadvantages of poor hearing aid effect need to be improved.
