Abstract

L'invention concerne un écran de présentation (32), par exemple un écran de projection qui comporte un panneau dont la surface réfléchit la lumière, caractérisé en ce que l'écran est un haut-parleur à élément radiant acoustique fonctionnant en mode réparti équipé d'un transducteur (9) monté totalement et exclusivement sur ce haut-parleur pour faire vibrer l'élément radiant et provoquer ainsi sa résonance pour fournir une puissance de sortie acoustique.
