Abstract

L'invention concerne un procédé permettant de fabriquer un élément acoustique capable de supporter les vibrations liées aux ondes de flexion. Ledit procédé consiste à utiliser un panneau (12) pour former un radiateur acoustique ; à identifier, sur ledit panneau (12), un point (14) de montage pour un transducteur (20) de vibrations destiné à exciter les ondes de flexion dans le panneau et à fixer des moyens raidisseurs (16) sur le panneau, au niveau du point (14) de montage du transducteur, de manière à renforcer le panneau localement. L'invention concerne également un haut-parleur (10) comprenant un radiateur acoustique (12) du type panneau à ondes de flexion et un transducteur (20) de vibrations monté sur ledit panneau (14) pour exciter les vibrations des ondes de flexion dans le panneau, lequel haut-parleur est caractérisé par un élément raidisseur (16) fixé localement au panneau du transducteur.
