A hearing aid having a bellows vibration body is disclosed. The hearing aid comprises: an external unit having a microphone for converting an external voice into an electrical signal; an internal unit which can be implanted under the skin and is for communicating with the external unit; a bellows vibration body which can be connected to the auditory ossicles and comprises a non-magnetic body; and an audio transmission tube for transmitting an acoustic signal, which is output from the internal unit, to the bellows vibration body, wherein the bellows vibration body vibrates in accordance with the acoustic signal transmitted by means of the audio transmission tube and thus transmits the vibration to the auditory ossicles.

Bellows vibration body and hearing aid comprising same

Provided are a vibration transducer and an implantable hearing aid device. In one embodiment, the implantable hearing aid device includes a signal processing part implantable in a subject, the signal processing part processing a signal from a microphone to output a sound signal, a sound transmission tube configured for transmitting the sound signal to a round window of the subject, and a bellows member disposed at an end side of the sound transmission tube to transmit vibration due to the sound signal to the round window. In other embodiment, the implantable hearing aid device includes a signal processing part implantable in a subject, the signal processing part processing a signal from a microphone to output an electrical signal, a vibration generation part configured for receiving the electrical signal to generate vibration, and a bellows member disposed at an end side of the vibration generation part to transmit the vibration to a round window of the subject. In some embodiments, the vibration generation part includes a magnet member or a piezoelectric vibration member to vibrate in accordance with the electrical signal.
