Partly implanted hearing aid
First Claim
1. An acoustic auditory aid device, generating at least an acoustic signal and designed to be fixed to the body of a patient, comprising:
- an external casing containing an electronic module for signal processing and having an input connected to at least one microphone and an output connected to an earphone designed to emit an acoustic signal in the external auditory canal of the patient, an energy source, at least one first magnetic part installed in the external casing, at least one second magnetic part installed in an implantable casing, designed to be implanted under the patient'"'"'s skin, at a location of the body where the external casing is to be supported, the first magnetic part being installed in the casing so that a magnetic force of attraction is exerted on the second magnetic part when the external casing is placed at said location, and a device for distribution of acoustic signals in the auditory canal of the patient comprising the earphone, and a connection between the external casing and the auditory canal of the patient, with a length such that the microphone can be kept sufficiently distant from the auditory canal to avoid Larsen phenomena.

Abstract
The invention concerns a hearing aid comprising: an outer housing (1) containing a signal processing module (11) connected in input to at least a microphone (13) and in output to an earphone for transmitting a sound signal into the patient'"'"'s external auditory canal (5); at least one first magnetic component (12) arranged in the outer housing (1); at least one second magnetic component (21) arranged in an implantable housing designed to be implanted under the patient'"'"'s skin, at a site where the outer housing (1) can be maintained, the first magnetic component being arranged in the outer housing such that a magnetic attraction force is exerted with the second magnetic component when the outer housing (1) is placed at said site; and a device for delivering sound signals into the patient'"'"'s external auditory canal comprising the earphone and a connection (4) between the outer housing (1) and the auditory canal.
