Abstract:
Methods and Apparatus for estimating a temperature of an electromechanical transducer. The method comprising receiving an audio signal ( 901 ); providing an output signal to the electromechanical transducer, based on the audio signal ( 902 ); and determining whether a first magnitude of the audio signal in a first frequency band is above a magnitude threshold ( 903 ). In response to the first magnitude being above or equal to the magnitude threshold, calculating a first impedance of the electromechanical transducer based on measurements of a first voltage and a first current of the electromechanical transducer within the first frequency band ( 905 ), and estimating the temperature of the electromechanical transducer based on the first impedance ( 907 ). In response to the first magnitude being below the magnitude threshold, inserting a pilot tone into the audio signal ( 909 ), wherein the pilot tone is at a pilot tone frequency, calculating a second impedance of the electromechanical transducer based on measurements of a second voltage and a second current of the electromechanical transducer at the pilot tone frequency ( 911 ), and estimating the temperature of the electromechanical transducer based on the second impedance ( 913 ).

Claim (Index 13):
A system as claimed in  claim 1  further comprising:\n a temperature modelling module configured to calculate a model temperature of the electromechanical transducer based on the estimated temperature and based on a temperature model of the electromechanical transducer; \n a power limitation module configured to, if the model temperature of the electromechanical transducer is above a first temperature threshold, attenuate the audio signal.
