Abstract:
A system and a method provide for protecting a loudspeaker from thermal and/or mechanical failure by monitoring for over-temperature and over-power conditions. The system generates a first gain from a first speaker protection controller in response to a driving voltage and/or a driving current of a loudspeaker, and generates a second gain from a second speaker protection controller in response to the driving voltage and/or a driving current of the loudspeaker, if the temperature exceeds a thermal limit or if the power exceeds a maximum power. The system applies the second gain to an audio signal to lower the audio signal if the first speaker protection controller fails.

Claim (Index 10):
A system comprising:\n a memory storing instructions for a first speaker protection controller to generate a first gain to protect a loudspeaker during operation; a processor coupled to the memory and operable to execute the instructions to cause the system to perform operations comprising:\n receiving a driving voltage of the loudspeaker; \n computing a temperature of the loudspeaker based on the driving voltage; \n comparing the temperature of the loudspeaker with a maximum temperature of the loudspeaker to determine an error value; \n generating the first gain if the error value is negative; \n a second speaker protection controller configured to generate a second gain in response to the driving voltage of the loudspeaker; and a detector configured to receive the first gain and the second gain, apply the first gain to an audio output signal when the first speaker protection controller is operable, and apply the second gain to the audio output signal when a failure is detect in the first speaker protection controller.
