Title
(EN) ELECTRODYNAMIC TRANSDUCER
(FR) TRANSDUCTEUR ELECTRODYNAMIQUE
Abstract
(EN) The invention relates to an electrodynamic transducer (1) comprising a magnetic mass (11) connected to the frame (5) via first and second axially offset suspension means (19), said means allowing translational displacement of the mass with respect to the frame, the suspension means having a plurality of basic springs, the direction of orientation of the basic springs of the first suspension means being opposite that of the basic springs of the second suspension means, such that each of the suspension means blocks axial rotation of the other suspension means.
(FR) L'invention concerne un transducteur électrodynamique (1) comprenant une masse magnétique (11) reliée au châssis (5) par un premier et un deuxième moyens de suspension (19) axialement décalés, lesdits moyens permettant un débattement de ladite masse en translation par rapport audit châssis, lesdits moyens de suspension présentant une pluralité de ressorts élémentaires, le sens d'orientation desdits ressorts élémentaires dudit premier moyen de suspension étant opposé à celui desdits ressorts élémentaires dudit deuxième moyen de suspension, de sorte que chacun desdits moyens de suspension bloque l'autre desdits moyens de suspension en rotation axiale.
