1. Hearing aid device comprising:
- an extra-buccal wireless transmitter part;
an intra-buccal wireless receiver transducer part for receiving signals from the transmitter part and comprising at least one vibrating element, said receiver part (1) being adapted to be fixed, in a removable manner, in the mouth of the user, and comprising means (3) for supporting and holding the vibrating element (2) in position, shaped so as to ensure, in a position of use, a permanent contact between said vibrating element and at least one of a tooth (4), and a palatine bone, thereby ensuring a transmission of sounds received as signals from the transmitter part, to the inner ear, exclusively by bone conduction, said vibrating element (2) being sealed and electrically insulated from the at least one of the tooth (4) and palatine bone.

Abstract
This invention provides a hearing aid of the kind which has a transmitter element and a receiver-transducer element having a vibrating element. The receiver element is suitable for being placed, preferably movably, in the mouth of the user. The receiver element includes a device for supporting and holding the vibrating element. The device for supporting and holding the vibrating element is formed so that when the vibrating element is in place it is in permanent contact either with at least one tooth or with the palate bone, thereby providing sound transmission to the inner ear by bone conduction.

- 8. Hearing aid device of the type comprising an extra-buccal transmitter part and an intra-buccal receiver transducer part comprising at least one vibrating element, wherein said receiver part (1) is adapted to be fixed, in a removable manner, in the mouth of the user, and it comprises means (3) for supporting and holding the vibrating element (2) in position, shaped so as to ensure, in the position of use, a permanent contact between said vibrating element and at least one of a tooth (4), and a palatine bone, thereby ensuring a transmission of the sounds to the inner ear by bone conduction, and said vibrating element (2) being sealed and electrically insulated, said vibrating element (2) comprising a metal plate (10) of small thickness coated on one side of its faces with a piezoelectric ceramic (13), said plate thus coated being contained in an envelope (14) constituted by a film of biocompatible polymer.
