PURPOSE: A free-type hearing aid with multi-shapes and multi-function is provided to reduce manufacturing costs by standardizing a pattern of an ear as various sizes. CONSTITUTION: An ear tip(100) is standardized as various sizes so that a hearing aid matches to most people using the hearing aid. A shell(200) is connected to the ear tip(100) as a coupling/dividing structure by a coupling groove(220) and a coupling sill(120) and is standardized as various sizes as a pattern of an ear. A face plate cover(300) is connected to the shell(200) as the coupling/dividing structure by the coupling groove(220) and the coupling sill(120). A face plate(400) is provided with an amplifier(420), a receiver(360), a battery room(560), and a volume controller(440) which are connected to the face plate cover(300) as the coupling/dividing structure by the coupling groove(220) and the coupling sill(120). A microphone(460) converts a voice signal into an electronic signal and is connected to the amplifier(420) mounted on the face plate(400). An acoustic guide tube(260) transfers the voice signal converted from the receiver(360) to an exit of an upper end of the shell(200).
