Method for controlling the temperature of a piece of sound reproduction equipment comprising: - an input for receiving an audio input signal to be reproduced; - a loudspeaker housed in an enclosure; - a processing and amplification chain comprising electronic components including at least an amplifier capable of exciting the loudspeaker, - a radiator adapted to dissipate the heat from the enclosure to the outside of the piece of equipment; said method being characterised in that it comprises the following steps which are carried out by an electronic temperature-control module and consist in: a/ collecting temperature data indicating the temperature of the radiator; b/ determining the thermal power P rad provided to the radiator by the components of the processing and amplification chain as a function of an evaluation of the thermal power P g emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced, of said audio input signal to be reproduced and of a model of heat transfer within the piece of sound reproduction equipment, then estimating the temperature outside the piece of sound reproduction equipment by means of a formula which gives the outside temperature T ext as a function of the temperature of the radiator T rad indicated by the collected data T rad, of the determined thermal power supplied at the input of the radiator P rad and of the thermal resistance of the radiator R th; c/ calculating the maximum thermal power P rad_max which can be supplied to the radiator as a function of the estimated outside temperature and of a maximum radiator temperature threshold Trad max and as a function of said formula; d/ determining the maximum thermal power to be emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced, as a function of the calculated maximum thermal power P rad_max and of said model of heat transfer within the piece of sound reproduction equipment; e/ determining, as a function of said determined maximum thermal power to be emitted, at least one command controlling the operation of the loudspeaker or of the processing and amplification chain such that the thermal power emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced is below said determined maximum thermal power to be emitted. - an input for receiving an audio input signal to be reproduced; - a loudspeaker housed in an enclosure; - a processing and amplification chain comprising electronic components including at least an amplifier capable of exciting the loudspeaker, - a radiator adapted to dissipate the heat from the enclosure to the outside of the piece of equipment; a/ collecting temperature data indicating the temperature of the radiator; b/ determining the thermal power P rad provided to the radiator by the components of the processing and amplification chain as a function of an evaluation of the thermal power P g emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced, of said audio input signal to be reproduced and of a model of heat transfer within the piece of sound reproduction equipment, then estimating the temperature outside the piece of sound reproduction equipment by means of a formula which gives the outside temperature T ext as a function of the temperature of the radiator T rad indicated by the collected data T rad, of the determined thermal power supplied at the input of the radiator P rad and of the thermal resistance of the radiator R th; c/ calculating the maximum thermal power P rad_max which can be supplied to the radiator as a function of the estimated outside temperature and of a maximum radiator temperature threshold Trad max and as a function of said formula; d/ determining the maximum thermal power to be emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced, as a function of the calculated maximum thermal power P rad_max and of said model of heat transfer within the piece of sound reproduction equipment; e/ determining, as a function of said determined maximum thermal power to be emitted, at least one command controlling the operation of the loudspeaker or of the processing and amplification chain such that the thermal power emitted by at least the loudspeaker and by the components of the processing and amplification chain for the audio input signal to be reproduced is below said determined maximum thermal power to be emitted.
