Abstract

Bei einer Einrichtung zur akustischen Wiedergabe eines von einem Tongenerator (2) abgegebenen elektrischen Audiosignales (i) ist ein Lautsprecher (1) vorgesehen, der eine feststehend angeordnete Erregerspule (11) sowie eine in deren Magnetfeld translatorisch auslenkbare Schwing-spule (12) aufweist, mit der ein Schall abgebendes Element (13) mechanisch gekoppelt ist. An den Tongenerator (2) ist ein mit einem digitalen Signalprozessor (4) ausgestatteter Signalwandler (3 bis 5) angeschaltet, der das Ausgangssignal (i) des Tongenerators in ein aufbereitetes Audiosignal (ia) entsprechend der Funktion ia = i1/2 umwandelt. Dieses aufbereitete Audiosignal wird in beide Lautsprecherspulen (11 bzw. 12), jedoch mit jeweils entgegengesetzter Stromflussrichtung eingespeist. In einer zweiten Ausführungsform ist ein elektrostatischer Lautsprecher (10) mit Feldplatten (101, 102) erster bzw. zweiter Art vorgesehen, die mit jeweils umgekehrter Polarität an den Signalwandler (3, 4, 5) angeschlossen sind.
