In a method for operating a loudspeaker device having at least one loudspeaker, at least one actual membrane state parameter of a membrane of the loudspeaker is detected by a detecting device. An actual membrane state of the membrane based on the following actual membrane state parameters: actual membrane position (xactual), actual membrane speed (vactual) and actual membrane acceleration (aactual), is determined from the at least one detected actual membrane state parameter (xactual, aactual) and is directly used to determine a driving signal (U(t)) that is applied to the voice coil of the loudspeaker. The voice coil is operatively connected to the membrane. A loudspeaker device being operated with this method and a device for noise compensation are also disclosed. |
