[0002] The cassette hearing aid is mainly composed of an amplifier, a microphone, a receiver, a switch, a volume adjustment knob and a shell. The cassette hearing aid is worn on clothes through a portable clip. When in use, the position of the cassette hearing aid is first fixed, then the earplug set on the surface of the hearing aid is placed in the ear, and then the ear-hanging structure is hung on the surface of the ear.
