Abstract (EN):
A typica l loudspeaker has some
nonlinearities that interfere with its behavior
causing the well-known distortions. In this
paper, we study two of the major
electromechanical nonlinearities, the motor
force factor and the suspension compliance.
First we found a model for nonlinear
loudspeaker simulation. The results were
compared with experimental observation,
validating the model. Two types of
compensation were introduced, one open
loop and one closed loop approaches,
showing that it is possible to improve
loudspeaker performance considerably.
This paper describes a preliminary study of
this type of compensation, aiming to
subsequent implementation using a digital
signal processor (DSP).
