technical field

The present invention relates to the technical field of hearing aids, in particular to an adjustable hearing aid with an anti-falling structure.

Background technique

Hearing aids are tools, equipment, devices and instruments that help people with hearing disabilities improve their hearing impairments and improve their ability to communicate with others. A weaker sound can be heard. Hearing aids are classified into behind-the-ear hearing aids, in-the-ear hearing aids, and box-type hearing aids according to their shapes.

Existing behind-the-ear hearing aids generally include a main unit, an earphone and a wire tube. The wire tube is pierced with a wire connecting the speaker of the earphone and the mainboard of the hearing aid of the main unit. The wire tube is generally an elastic structure so that people can adjust the angle of the earphone slightly; There are limitations in the use of behind-the-ear hearing aids. Due to the different ear types of different users, the wire tube of the hearing aid is of a fixed length, which leads to the possibility of falling off easily when worn. Generally, the host is also clamped between the auricle and the head. In this way, when the user is active, the host will easily shake, which not only affects the position of the earphone in the ear hole, but also is prone to falling.
