Abstract: The invention relates to a processing device for processing an input signal (Si), generating an output signal (So) intended to be fed to a loudspeaker, said device comprising a processing line (Lt) comprising: an estimation module for estimating expected movements (Da) of the loudspeaker based on the input signal (Si); a determination module for determining an adaptive control signal (CmdA) to be transmitted to the loudspeaker in order to get as close as possible to the expected movements (Da) while correcting the nonlinearities of the loudspeaker; at least one transmission line (L1, L2) for the input signal (Si), delivering at least one non-adaptive control signal (Cmd1); and an adder, delivering the output signal (So) by summing the adaptive control signal (CmdA) and the at least one non-adaptive control signal (Cmd1).
