A wearable hearing aid

Abstract

The invention discloses a wearable hearing aid, which comprises a right sleeve rod and a left sleeve rod, the outer wall of one side of the right sleeve rod is provided with a first rectangular groove, and the inner wall of the first rectangular groove is slidably connected with a second A right telescopic rod, the outer wall of one side of the first right telescopic rod is provided with a second rectangular groove, and the inner wall of the second rectangular groove is slidably connected with a second right telescopic rod, and one side of the second right telescopic rod The outer wall is connected with the right magnetic strip by screws, the outer wall of one side of the left sleeve rod is provided with a third rectangular groove, and the inner wall of the third rectangular groove is slidably connected with the first left telescopic rod. The spherical magnet of the present invention departs from the circular groove, the telescopic rod slides into the sleeve rod, and the rotating shaft puts away the behind-the-ear earphone, completing the storage of the wearable earphone, so that the hearing aid is not easy to be crushed and causes property loss when placed, and the hearing aid The shrinkage volume is reduced to avoid the phenomenon of inconvenient carrying, bumping and damage when not in use.

Description

technical field [0001] The invention relates to the technical field of hearing aids, in particular to a wearable hearing aid. Background technique [0002] A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain so that the sound can be felt. The types of hearing aids can be divided into: box type, behind-the-ear type, and in-ear type from the external structure, and the in-ear type can be divided into ordinary in-ear type, ear canal type, and deep ear canal type; from the electronic principle can be divided into: analog hearing aids ; Programmable hearing aids, full digital hearing aids, wide dynamic language technology hearing aids, etc.; divided into air conduction hearing aids and bone conduction hearing aids according to the conduction method. Cassette, behind-the-ear, and in-ear are all air conduction hearing aids. [0003] Wear...

AI Technical Summary

Problems solved by technology

[0003] Wearable hearing aids currently on the market are bone conduction hearing aids and glasses-type hearing aids, which can be worn directly. There is a certain curvature, and it is easy to be crushed when placed, resulting in property loss, and the structure of the wearable hearing aid is fixed, the required space and access box are larger, and it is easy to cause inconvenient portability and bump damage when not in use
