Disclosed is a hearing aid in which a receiver is provided in a form implanted into the mastoid antrum. In the hearing aid, an output device is used while being disposed at a position separated from an input device, so that the hearing aid is less affected by feedback and does not have sound feedback even at a high output, and thus the hearing aid is applicable to people having moderate to severe hearing loss. Further, an implantation operation method for locating the output device in the mastoid antrum is simple and it is possible to obtain constant hearing aid performance regardless of the level of the implantation technology of the output device. Still further, a receiver using air as an output medium is implanted into the mastoid antrum, so that the implantable hearing aid has small resistance to the output medium and has high output efficiency.

Hearing aid

A microphone for an implantable hearing aid includes a body part having a cylindrical housing installed to pass through a tympanum and a microphone controller installed within the cylindrical housing to convert an acoustic signal into an electrical signal, an acoustic collection part that provides a passage for transmitting external sounds into the body part, the acoustic collection part being disposed on one end of the body part in a direction of an external auditory meatus, and a wire connection part connecting the microphone controller to the hearing aid, the wire connection part being disposed on the other end of the body part in a direction of a middle ear cavity. The microphone is easily installed on the tympanum in a noninvasive manner, and attenuation in sensibility of the microphone is prevented. Thus, the microphone may be significantly utilized for the implantable hearing aid.
