Abstract

Un dispositif électronique selon un mode de réalisation divulgué ici peut comprendre : un module audio ; un ventilateur de refroidissement ; une mémoire ; et un processeur connecté fonctionnellement au module audio, au ventilateur de refroidissement et à la mémoire. Selon un mode de réalisation, la mémoire peut stocker des instructions qui, lorsqu'elles sont exécutées, amènent le processeur à : reconnaître des informations relatives à la puissance de sortie de données audio à travers le module audio ; reconnaître des informations de fréquence des données audio par l'intermédiaire du module audio ; et commander la vitesse de rotation du ventilateur de refroidissement sur la base de la puissance de sortie reconnue et des informations de fréquence reconnues. Divers autres modes de réalisation identifiés à partir de la description sont possibles.
