[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 sound can be felt. It mainly consists of five parts: a sound transmission port, an amplifier, headphones, a power supply, and a 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, in-the-ear, ear canal, and deep ear canal hearing aids according to the usage method.
