Abstract

Système acoustique (1) pour diffuser du son à partir de N canaux (Si) comportant des fréquences audio, N étant supérieur ou égal à deux, le système acoustique comprenant un châssis (5), M haut-parleurs (HPj) analogues les uns aux autres et montés sur le châssis (5), et une unité de traitement (20) adaptée pour envoyer M signaux de haut-parleur (SSj) respectivement aux haut-parleurs. Les haut-parleurs sont disposés angulairement autour d'un axe (Z), deux haut-parleurs successifs formant un angle (α) sensiblement égal à 360° divisé par_M. L'unité de traitement (20) comporte un répartiteur (28) configuré pour produire les signaux de haut-parleur (SSj), chaque signal de haut-parleur comportant une même composante grave commune (SSLF) dans laquelle les fréquences audio supérieures à une première fréquence (f1) prédéterminée sont inexistantes ou réduites, au moins deux des signaux de haut-parleur comportant en outre une composante spécifique (SSj,MF) s'ajoutant à la composante grave commune et dans laquelle les fréquences audio inférieures à la première fréquence sont inexistantes ou réduites, chaque composante spécifique étant obtenue à partir d'au moins un des canaux, et au moins deux des composantes spécifiques étant différentes l'une de l'autre.
