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.
