Problems solved by technology

This type of device does not work well if the skin is surgically made very thin, as insufficient blood supply in the stressed skin can lead to skin necrosis
There is a need for a more effective hearing aid system that is reliable and does not have the disadvantages described above

Embodiment Construction

[0030]FIG. 1 is a side sectional view of a hearing aid system 500 of the present invention. The external hearing aid unit 501 has a vibrator 502 built therein. The vibrator 502 may be an assembled integrated unit such that all vibrator elements may be placed within the external hearing aid unit 501 . Preferably, the vibrator 502 has a vibrator plate 518 connected to a skin contact pressure plate 538 by a connecting portion. Skin contact pressure plate 538 is magnetic such that it is magnetically attracted to magnetic portion 540 of implant unit 530 , which is anchored in skull 506 by fixation portion 526 . This magnetic interaction presses skin contact pressure plate 538 against skin 504 . The vibrations are conducted from the integrated vibrator 502 to the skin contact platen 538 and then through the skin 504 of the skull 506 to the implant unit 530 . Skin contact pressure plate 538 may also be made of a suitable non-magnetic material such as metal that is magnetically att...

Abstract

A bone conduction hearing aid system for generating bone conduction vibrations is disclosed. The bone conduction hearing aid system has an external hearing aid unit with a vibrator and a skin contact pressure plate. The skin contact pressure plate is placed on an outside of the external hearing aid unit and the skin contact pressure plate is magnetically attached to an implanted unit anchored to the skull under the skin. The vibrator transforms an electrical signal into mechanical vibrations and the skin contact pressure plate allows transmission of the vibrations from the vibrator to the implanted unit when the external hearing aid unit is magnetically fixed to the implanted unit.

Description

technical field [0001] The present invention relates to a hearing aid system for providing bone conduction hearing. Background of the invention [0002] Bone conduction works by transmitting vibrations through the skull bone to the inner ear, the cochlea. There are many different types of bone conduction hearing aids. But they all have significant disadvantages for the patient, as described below. [0003] A traditional bone conductor consists of a hearing aid with a vibrator pressed against the head behind the ear by a spring arrangement extending from the other side of the head. A steel spring mechanism is sometimes built into the spectacle-like frame. Vibrations are conducted to the cochlea through the skin and skull. Conventional bone conductors with a spring mechanism surrounding the head and constantly applying pressure to the skull often cause headaches, which patients often complain of. [0004] Another type of bone conductor, sometimes called a direct bone cond...
