Abstract

L'invention concerne un convertisseur de signaux électriques en vibrations mécaniques dans la bande des fréquences audibles. Il comporte une culasse avec un pôle magnétique et un entrefer supporté par un amortisseur dans un carter fixé et encastré dans une plaque vibrante Une bobine fixée au carter est placée dans l'entrefer et le carter produit des vibrations mécaniques synchronisées avec un signal audible en basse fréquence. L'invention s'applique notamment à la reproduction des sons de la contrebasse.
