Abstract

Die Erfindung betrifft eine Anordnung zur akustischen Gegenkopplung von Lautsprechern, mit zumindest einem Mikrophon 2, das eine dem vom Lautsprecher 1 erzeugten Schalldruck proportionale Spannung liefert, mit einem Mi­ krophonverstärker 3, mit einer Summierstelle 4, welche die verstärkte Mikrophonspannung gegenphasig zum Ansteu­ ersignal des Lautsprechers 1 addiert, mit einem der Sum­ mierstelle 4 nachgeschalteten PI-Regler 5 sowie mit einem nachfolgenden Leistungsverstärker 6 zur Ansteuerung des Lautsprechers 1. Gemäss der Erfindung ist das Mikrophon 2 auf der Lautsprechermembran angebracht.
