Abstract

Es wird ein elektrodynamischer Treiber für eine Membran (12) vorgeschlagen, der eine auf einem rohrförmigen Spulenträger (8a) aufgebrachte Schwingspule (8), ein bezüglich der Schwingspule (8) konzentrisch angeordnetes, axial bewegliches Magnetsystem (4, 5, 6), einen Adapter (9) zum Befestigen des Spulenträgers (8a) an der Membran (12) und ein zwischen Membran (12) und Magnetsystem (4, 5, 6) angeordnetes elastisches Element (2, 7, 23b) aufweist. Dabei bildet sich mindestens ein Hohlraum (10, 11, 15, 17) zwischen Membran (12) und Magnetsystem (4, 5, 6), der mit Mitteln zum Druckausgleich (14, 16, 19, 20, 21, 24) des mindestens einen Hohlraums (10, 11, 15, 17) in Verbindung steht.
