HEARING DEVICE WITH A SOUND TRANSDUCER AND METHOD FOR PRODUCING A SOUND TRANSDUCER
First Claim
1. A hearing device, comprising:
- a sound transducer having;
a field generation apparatus for generating an electric or magnetic field; and
an emission apparatus for generating sound, said emission apparatus having a multiplicity of fingers disposed to be penetrated by the field of said field generation apparatus, said fingers having a shape to be changed by way of the field of said field generation apparatus in order to generate the sound.

Abstract
In hearing devices, more particularly in hearing aids, it is desirable to be able to design an earpiece for generating sound in the audible range which is as small as possible. Such an earpiece can then be worn comfortably on an ear or in an auditory canal. A sound transducer for the hearing device disclosed here may be formed as a micro-electromechanical system and the transducer enables generation of an acoustic signal with little distortion. Provision is made for a hearing device with a sound transducer, which has a field generation apparatus for generating an electric or magnetic field and an emission apparatus for generating sound. Here, the emission apparatus has a multiplicity of fingers that are penetrated by the field of the field generation apparatus, wherein the shape of the fingers can be changed by means of the field of the field generation apparatus in order to generate the sound.

16. A method for producing a sound transducer with a multiplicity of fingers for generating sound, the method which comprises:
-
providing a substrate; arranging a protective layer on a front side of the substrate, wherein a shape of the fingers is determined by a profile of an edge of the protective layer; and applying a medium for dissolving the substrate to the front side and a rear side of the substrate. - View Dependent Claims (17)
