Abstract

L'invention se rapporte à un dispositif autonome conçu pour induire des ondes acoustiques dans un panneau de sorte que le panneau diffuse un son audible. Ce dispositif comporte un boîtier (1) contenant (a) une source d'énergie, par exemple des batteries de piles sèches; (b) un organe d'entrée (2) de signaux basse fréquence reçus d'une source de signaux externe telle qu'une stéréo personnelle, ou un organe générateur de signaux basse fréquence tels qu'un lecteur audio ou un téléphone; (c) un amplificateur connecté à la source d'énergie et à l'organe d'entrée de signaux et délivrant un signal de sortie; (d) un actionneur basse fréquence (4) connecté au circuit de sortie audio et conçu pour s'accoupler acoustiquement au panneau lorsque le dispositif est amené en contact dudit panneau.
