Abstract

Die Erfindung betrifft einen elektroakustischen Wandler nach dem Kondensatorprinzip, mit einer im wesentlichen starren Elektrode (8) und mit einer als Membrane (7) ausgebildeten flexiblen Elektrode, wobei im Zentrumsbereich der Elektroden der Abstand zwischen der Membrane (7) und der starren Elektrode (8) geringer ist als in deren Randbereich, und gegebenenfalls mit einem Resonatorvorsatz (4).The invention relates to an electroacoustic transducer according to the capacitor principle, comprising a substantially rigid electrode (8) and a flexible electrode designed as a membrane (7), wherein in the center region of the electrodes the distance between the membrane (7) and the rigid electrode (8 ) is smaller than in its edge region, and optionally with a Resonatorvorsatz (4).

Die Erfindung ist dadurch gekennzeichnet, daß die Membrane (7) kegel- oder kegelstumpfförmig deformiert ist.The invention is characterized in that the membrane (7) is deformed in a cone or truncated cone.

In einer bevorzugten Variante wird dies dadurch erreicht, daß die starre Elektrode (8) in ihrem zentralen Bereich einen zumindest im wesentlichen kreiszylindrischen Vorsprung (9) aufweist, und daß die Membrane (7) an diesem Vorsprung (9) anliegt, beispielsweise durch einen am Resonatorvorsatz (4) befestigten Nippel (3) angepreßt wird.In a preferred variant, this is achieved in that the rigid electrode (8) in its central region has an at least substantially circular cylindrical projection (9), and in that the membrane (7) rests against this projection (9), for example by an am Resonator attachment (4) attached nipple (3) is pressed.

Die Erfindung betrifft weiters Ausgestaltungen dieses Erfindungsgedankens.
