Abstract

Transducteur (1) comportant un châssis (5) définissant un volume de réception d’une bobine (9) enroulée autour d’un mandrin (8), et positionnée dans l’entrefer (10) entre un aimant permanent annulaire (13) et un cylindre (12) métallique, ces deux éléments formant une masse magnétique (11) mobile par rapport à la bobine (9), caractérisé en ce que la masse magnétique (11) est reliée au châssis (5) par au moins deux ressorts (19), circulaires antagonistes, parallèles entre eux et perpendiculaires au sens de déplacement (F)de la masse magnétique (11).
