Abstract

Ein Mikrofonmodul aus einer Mikrofonkapsel (2) mit angesetzter Verstärkerplatine (4) ist mit einer Abschirmung in Form einer Halbschale versehen, welche die auf einer Seite der Platine befindlichen Verstärkerbauelemente umschließt und mit der auf der gegenüberliegenden Seite der Platine befindlicher durchgehenden Metallkaschierung verlötet ist. Die Abschirmwanne umgibt die in sie eingepaßte Hälfte der metallischen Mikrofonkapsel unter Kontaktgabe. Die über die Platine (2) hinausragende Hälfte der Rückseite der Mikrofonkapsel ist mit einer metallisierten Abschirmung (14) versehen, die mit dem Kapselgehäuse und mit der Kaschierung (12) der Platine (4) Kontakt hat. Die Verstärkerschaltung auf der Platine ist somit vollständig abgeschirmt und wirksam gegen Störeinstreuungen geschützt. Zur Erzielung einer gewünschten Richtwirkung sind auf der Rückseite der Mikrofonkapsel (2) Schalldrucköffnungen (22) angeordnet, und um deren Wirksamkeit zu erhalten bzw. zu verbessern ist die Verstärkerplatine (4) an ihrer mikrofonseitigen Kante mit entsprechenden Ausnehmungen (24) versehen.
