Abstract

Ein Tiefton-Membranlautsprecher besitzt ein Gehäuse (10), dessen Gehäusewandungen (13, 14, 15) ein Volumen (25) umschliessen, welches auf der Rückseite seiner Membran (3) ausgebildet ist. In einer das Volumen (25) begrenzenden Fläche der Gehäusewandungen (13, 14, 15) ist eine Öffnung (23) vorhanden. Das Volumen (25) ist so klein vorhanden, dass die Resonanzfrequenz, bei der die Schwingungen des Verstärkers den Schwingungen der Membran (3) grössenmässig entsprechen, oberhalb von 200 Hz (Hertz), insbesondere oberhalb von 1000 Hz (Hertz), liegt und sich damit im Frequenzbereich eines Mittelton- oder Hochton-Lautsprechers befindet. Dabei ist die Öffnung (23) so ausgebildet, dass bei jeder Frequenz des Tiefton-Membralautsprechers Luft aus dem Volumen mit grosser Luftgeschwindigkeit heraustritt.
