Abstract

L'invention concerne un dispositif de vibration (100) qui comporte : une base (10) qui fixe une plaque (20) et la périphérie de la plaque (20) ; une unité de vibration (40) qui amène une pluralité de côtés de la plaque (20) à vibrer ; et un dispositif de commande (80) qui commande la vibration de l'unité de vibration (40). L'unité de vibration (40) amène des côtés (23) de la plaque (20) à vibrer vers le haut et vers le bas, génère des ondes progressives dans les côtés (23) de la plaque (20) à la même amplitude, à la même longueur d'onde, et à la même fréquence, et amène la plaque (20) à vibrer en tant qu'onde stationnaire.
