Abstract

Bei Hörvorrichtungen, insbesondere bei Hörgeräten, ist es erwünscht, einen Hörer zum Erzeugen von Schall im hörbaren Bereich möglichst klein ausbilden zu können. Ein solcher Hörer lässt sich dann bequem an einem Ohr oder in einem Gehörgang tragen. Es ist Aufgabe der vorliegenden Erfindung, für eine Hörvorrichtung einen Schallwandler bereitzustellen, welcher als mikro-elektromechanisches System ausgebildet werden kann und mittels welchem sich ein akustisches Signal mit einer geringen Verzerrung erzeugen lässt. Erfindungsgemäß wird dazu eine Hörvorrichtung mit einem Schallwandler (38) bereitgestellt, welche eine Felderzeugungseinrichtung (24) zum Erzeugen eines elektrischen oder magnetischen Felds und eine Abstrahleinrichtung (22) zum Erzeugen eines Schalls aufweist. Die Abstrahleinrichtung weist dabei eine Vielzahl von Fingern (10) auf, die von dem Feld der Felderzeugungseinrichtung (24) durchdrungen werden, wobei
die Form der Finger (10) mittels des Felds der Felderzeugungseinrichtung (24) veränderbar ist, um den Schall zu erzeugen.

In the case of hearing devices, in particular in the case of hearing aids, it is desirable to be able to make a listener as small as possible for generating sound in the audible range. Such a receiver can then be comfortably worn on one ear or in one ear canal. It is an object of the present invention to provide for a hearing device a sound transducer, which can be formed as a micro-electro-mechanical system and by means of which can generate an acoustic signal with a low distortion. According to the invention, a hearing device with a sound transducer (38) is provided, which has a field generating device (24) for generating an electric or magnetic field and an emitting device (22) for generating a sound. The emitting device in this case has a plurality of fingers (10) which are penetrated by the field of the field generating device (24), wherein
the shape of the fingers (10) is variable by means of the field of the field generating means (24) to generate the sound.
