Abstract

L'invention a trait à un haut-parleur à panneaux. Ce haut-parleur comporte au moins deux panneaux acoustiques fonctionnant en mode résonnant réparti. Il est doté d'une seule unité de commande destinée à exciter tous les panneaux de telle manière que l'énergie de l'onde de flexion soit transmise efficacement à chacun de ces panneaux aux fins d'exciter leur résonance en mode réparti et ce, dans le but de provoquer une sortie acoustique. Le haut-parleur peut comporter deux panneaux, l'un étant plus grand que l'autre, le plus grand présentant une rigidité d'onde de flexion inférieure à celle du petit. Le petit panneau est positionné de manière excentrique par rapport au grand panneau. L'unité de commande est positionnée de manière excentrique par rapport au petit panneau. Une pluralité de petits panneaux peuvent être associés à un seul grand panneau. Selon un mode réalisation, une unité de commande montée sur le petit panneau, ou sur chaque petit panneau, est fixée par la voie adhésive, face à face par rapport au grand panneau. Selon un autre mode réalisation, le petit panneau, ou chaque petit panneau, est formé à l'intérieur du grand panneau et fixé sur celui-ci, une unité de commande étant fixée au petit panneau, ou à chaque petit panneau. La fixation des panneaux nécessite l'utilisation d'une matière formant un couplage de commande adapté. Selon un troisième mode de réalisation, le petit panneau, ou chaque petit panneau, est fixé au niveau d'une extrémité d'un coupleur associé traversant le grand panneau, et fixé sur celui-ci, une unité de commande étant fixée au niveau de l'autre extrémité du coupleur, ou de chaque coupleur. La fixation du coupleur, ou de chaque coupleur, au grand panneau nécessite l'utilisation d'une matière formant un couplage de commande adapté. Le coupleur, ou chaque coupleur, présente une coupe transversale tubulaire.
