Abstract

L'invention concerne un haut-parleur composé d'un panneau (1) soutenant des ondes de flexion et un transducteur (3) couvrant une large partie de la surface du panneau. Au moins une contrainte, par exemple, un dispositif de fixation, est attaché au panneau. Chaque contrainte réduit la mobilité d'une petite partie du panneau. L'excitation du transducteur excite à son tour les ondes de flexion dans le panneau, les contraintes empêchant le mouvement simple et stimulant, en revanche, la production de plusieurs ondes de flexion. Les contraintes peuvent obliger le panneau à être excité, afin de produire une bonne distribution de modes d'ondes de flexion.
