Abstract
An audio system may include a plurality of transducers, a temperature estimator, and a thermal control subsystem. The temperature estimator may be configured to monitor physical quantities associated with a plurality of transducers and based on the physical quantities, determine an estimated temperature associated with a first transducer of the plurality of transducers. The thermal control subsystem may be configured to generate an output signal based on an input signal, the output signal for driving the plurality of transducers and control the output signal based on the estimated temperature.
