Description

Technical Field

[0001] The present invention relates to the field of hearing aids, in particular to a high-stability hearing aid. Background Art

[0002] A hearing aid is a small loudspeaker that amplifies sounds that are not audible, and then uses the residual hearing of the hearing-impaired to send the sounds to the auditory center of the brain, so that the hearing-impaired can feel the sounds. This brings great convenience to the hearing-impaired.

[0003] Currently, the appearance of many hearing aids is similar to that of headphones. When in use, most of the sound tubes are stuck on the user's ears, and there is no other fixing structure when worn. As a result, the hearing aids are prone to shaking when the user is running, and the stability is poor. When the user stores the hearing aid, if it is placed in a pocket or bag, the hearing aid shell and earplug are easily squeezed. The squeezed hearing aid sound tube is not fixed, and if it is squeezed for too long, it is easy to deform, affecting the user's subsequent use. Summary of the invention
