Abstract

L'invention concerne un transducteur de vibrations (9) destiné à faire vibrer un élément (2) qui a une face, caractérisé: par un ensemble bobine d'entraînement dont la bobine (13) est fixée de manière rigide à une pièce tubulaire (18), cet ensemble étant destiné à être rattaché à ladite face de l'élément, et par un ensemble aimant (15) qui comprend des pièces opposées en forme de disque tenant lieu de pôle; la périphérie de l'une de ces pièces est destinée à être installée avec l'ensemble bobine d'entraînement, en position adjacente, tandis que la périphérie de l'autre pièce comporte une bride de pourtour (90) conçue pour entourer l'ensemble bobine d'entraînement, également en position adjacente. Enfin, le transducteur est caractérisé en ce que l'ensemble aimant est destiné à être fixé en son centre à l'élément qui doit être mis en vibration.
