Abstract
One embodiment provides a method comprising determining a potential energy in a loudspeaker, a kinetic energy in the loudspeaker, and an electrical energy in the loudspeaker based on a physical model of the loudspeaker. The method further comprises determining a total energy stored in the loudspeaker based on the potential energy, the kinetic energy, and the electrical energy. The method further comprises determining a maximum potential displacement of a diaphragm of a speaker driver of the loudspeaker based on the total energy, and limiting the total energy stored in the loudspeaker by attenuating a source signal for reproduction via the loudspeaker. An actual displacement of the diaphragm during the reproduction of the source signal is controlled based on the attenuated source signal.
