DEVICE FOR CONTROLLING A LOUDSPEAKER

摘要

The present invention relates to a device for controlling a loudspeaker (14) in an enclosure, comprising:;an input for an audio signal (Saudio_ref) to be reproduced;;an output for supplying an excitation signal from the loudspeaker.;It comprises a control unit comprising:;means (24, 25) for calculating a desired dynamic value (Aref) of the loudspeaker diaphragm based on the audio signal (Saudio_ref) to be reproduced and the structure of the enclosure;;means (26) for calculating a plurality of desired dynamic values (Aref, dAref/dt, Vref, Xref) of the loudspeaker diaphragm at each moment based on only the desired dynamic value (Aref);;a mechanical model (36) of the loudspeaker; and;means (70, 80, 90) for calculating the excitation signal of the loudspeaker at each moment, without feedback loop, from the mechanical model (36) of the loudspeaker and desired dynamic values (Aref, dAref/dt, Vref, Xref).
