Abstract

La présente invention concerne un haut-parleur (81) à structure en panneau constitué d'un élément acoustique radiant résonant, fonctionnant en mode distribué. Cet élément est caractérisé par un transducteur (9) monté sur l'élément radiant de façon à exciter dans l'élément radiant une résonance en mode distribué, et par un cadre (1) servant de support à l'élément radiant, le transducteur étant couplé entre l'élément radiant et le cadre de façon à faire vibrer le panneau et donc à le faire entrer en résonance, produisant ainsi une sortie acoustique. Ce haut-parleur est caractérisé par le cadre qui sert de support à l'élément radiant sur son pourtour, et par un organe de suspension élastique couplé entre le cadre et le pourtour de l'élément radiant.
