Abstract

L'invention concerne, selon un mode de réalisation, un dispositif de commande de haut-parleur comprenant : un premier processeur qui délivre en sortie un premier signal de fonctionnement obtenu à partir d'un signal d'entrée en fonction de caractéristiques de réponse sur la base d'un premier paramètre qui stipule le circuit d'égalisation pour une première unité de haut-parleur ; une unité de génération de signal de commande qui génère un signal de commande pour commander l'unité de haut-parleur sur la base du premier signal de fonctionnement ; et une unité de modification qui modifie les caractéristiques de réponse du premier processeur sur la base des caractéristiques obtenues successivement à partir du signal d'entrée.
