Abstract
The present invention relates to a device for controlling a loudspeaker () in an enclosure, comprising: It comprises means () for calculating the excitation signal, means () for calculating a desired dynamic value (A) of the diaphragm of the loudspeaker based on the audio signal (S) to be reproduced and the structure of the enclosure, the means () for calculating the desired dynamic value (A) of the loudspeaker diaphragm being able to apply a correction that is different from the identity, and taking account of structural dynamic values (x, v) of the enclosure that are different from the only dynamic values relative to the loudspeaker diaphragm, and the means () for calculating the excitation signal of the loudspeaker being able to calculate the excitation signal based on the desired dynamic value (A) of the loudspeaker diaphragm.
