Abstract
A system includes a gain control circuit configured to dynamically select a gain value based on an estimated temperature for a speaker voice coil, a base gain value, and a threshold temperature value. The system also includes a power control circuit configured to determine a power limit value based on the gain value. The system also includes a filter circuit configured to adjust values of a digitized audio signal based on the power limit value. The system also includes a digital-to-analog converter (DAC) coupled to the filter circuit and configured to convert a digital output of the filter circuit to an analog audio signal.
