Abstract

Die Erfindung betrifft einen elektroakustischer, als Schallnehmer arbeitenden, in eine Mikrofonkapsel einbaubaren, auf elektrostatischer Basis arbeitenden Wandler mit einer Elektrode (5) und einer Membrane (1), die durch einen Distanzring (4) in Abstand voneinander gehalten werden.
Die Erfindung ist dadurch gekennzeichnet, dass an der Elektrode (5), bevorzugt auf der der Membrane (1) abgewandten Seite, zumindest ein elektrischer Widerstand (7) angeordnet, bevorzugt angeklebt, ist, der während des Betriebes des Mikrofons mit einer Spannungsquelle verbunden ist.
In einer Ausgestaltung ist ein spezieller Regelkreis vorgesehen, der die Außentemperatur berücksichtigt.
