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.
