Abstract

Cette invention concerne un système de restitution des sons en trois dimensions, lequel système comprend une source (1) de signal à voies multiples, ainsi que des voies de restitution des sons. Chaque voie de restitution des sons comprend les éléments suivants: un amplificateur à basse fréquence (2, 7) et un haut-parleur (2, 8) montés en série; un dispositif de sondage (4, 8); un dispositif de réglage automatique (5, 10) des caractéristiques du signal; et enfin, une ligne de connexion (6, 11). La sortie du dispositif de sondage (4, 9) est reliée par la ligne de connexion (6, 11) à la première entrée du dispositif de réglage automatique (5, 10) des caractéristiques du signal. La seconde entrée de ce dernier est, quant à elle, connectée à la sortie de la source de signal (1), tandis que sa sortie est connectée à l'entrée de l'amplificateur à basse fréquence (2, 7).
