Abstract
Ein elektrodynamischer Lautsprecher mit einem ein Magnetfeld (14) erzeugenden Magneten (3), einer Schwingspule (6) und einer um eine Mittellage schwingenden Membran (2) weist eine Regeleinrichtung auf, mit der eine Mittellagen-Abweichung der Membran (2) mit Hilfe eines Sensors (10) detektierbar und die Schwingspule (6) mit einer der Abweichung entgegenwirkenden Gleichspannung beaufschlagbar ist. An electrodynamic loudspeaker with a magnet (3) generating a magnetic field (14), a voice coil (6) and a membrane (2) vibrating around a central position has a control device with which a central position deviation of the membrane (2) can be determined using a Sensor (10) is detectable and the voice coil (6) can be acted upon by a DC voltage counteracting the deviation.
