Abstract

Cette invention concerne un ensemble acoustique à effet spatial amélioré. Cet ensemble comprend deux ou plusieurs enceintes équipées elles-mêmes d'un ou plusieurs haut-parleurs ou groupes de haut-parleurs émettant chacun des ondes sonores dans une bande de fréquences définie. Ces haut-parleurs sont répartis en alternance entre les enceintes selon leur échelonnement de bandes de fréquences, afin que les haut-parleurs d'une enceinte émettent dans des bandes de fréquences séparées par un écart correspondant à au moins une bande de fréquences d'émission par un haut-parleur. Cet agencement, conjugué notamment à des haut-parleurs à émission annulaire sensiblement sur 360 degrés , fournit un effet spatial amélioré.
