Abstract

Die Erfindung betrifft eine elektrostatische Mikrofonkapsel mit einer Membrane, die dem Schallfeld ausgesetzt ist und von diesem zu Schwingungen angeregt wird und mit einer im Abstand von der Membrane angeordneten Elektrode (1)
Die Erfindung ist dadurch gekennzeichnet, dass die Elektrode (1) zumindest zwei Bereiche (4,5) mit unterschiedlicher Ladungsdichte aufweist.
In einer bevorzugten Ausgestaltung ist vorgesehen, dass die zumindest beiden Bereiche (5,6) aus einem zumindest im wesentlichen kreisförmigen (4) und zumindest einem im wesentlichen ringförmigen (5) Bereich bestehen.
