Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hearing aids, in particular to a hearing aid capable of anti-fatigue support. 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] Hearing aids are mainly composed of microphone, amplifier, earphone, power supply and volume control. Hearing aids are divided into air conduction hearing aids and bone conduction hearing aids according to the conduction method; and are classified into box type, glasses type, hairpin type, behind-the-ear type, in-the-ear type, ear canal type, and deep ear canal type according to the usage method.
[0004] Hearing aids bring great convenience to the hearing-impaired. With the development of microelectronics technology, hearing aids have become increasingly small and micro. Hearing aids worn by people are prone to fall off and get lost after being hit by external forces. When performing rehabilitation training for disabled children, wearing hearing aids in the ears for a long time will cause ear fatigue and fall off. It is necessary to use hearing aids with anti-fatigue support to prevent hearing aids from falling off and oppression on the ears when disabled children use them. Therefore, we have launched a hearing aid with anti-fatigue support. Utility Model Content
