System and method for providing advanced loudspeaker protection with over-excursion, frequency compensation and non-linear correction

A method comprising:

• receiving, at an audio amplifier, an audio input signal;
• providing a target voltage across a voice coil of a loudspeaker based on the audio input signal;
• generating an audio output after providing the target voltage across the voice coil;
• determining a current through the voice coil of the loudspeaker based on generating the audio output;
• determining an average power loss in the voice coil based at least on the current;
• and
• reducing a signal level of the target voltage responsive to the average power loss in the voice coil being greater than a predetermined threshold.

A non-transitory computer readable medium storing a computer-program product embodied in a non-transitory computer readable medium that is programmed to generate an audio output, the computer-program product comprising instructions to:

• receive, at an audio amplifier, an audio input signal;
• provide a target voltage across a voice coil of a loudspeaker based on the audio input signal;
• generate an audio output after providing the target voltage across the voice coil;
• determine a current through the voice coil of the loudspeaker based on generating the audio output;
• determine an average power loss in the voice coil based at least on the current;
• and
• reduce a signal level of the target voltage responsive to the average power loss in the voice coil being greater than a predetermined threshold.
