Abstract

L’invention concerne un excitateur (1) audio comprenant une bobine (2) électromagnétique et un circuit magnétique formé d’un corps (3) comprenant un noyau (3a) aimanté et un élément périphérique (3b) s’étendant autour du noyau pour former un entrefer. L’excitateur comprend une suspension (8) reliant la bobine au corps de sorte que la bobine se déplace par rapport au corps selon un axe longitudinal (AA’) dans l’entrefer autour du noyau. L’excitateur comprend également un élément (4) de contact fixé sur une extrémité (2a) de la bobine qui recouvre l’ouverture (2b) de la bobine et qui comprend une face extérieure (5) destinée à être en contact avec une surface (S) à faire vibrer et une face intérieure (6) faisant face au noyau. La suspension s’étend de la face intérieure de l’élément de contact jusqu’au noyau pour fonctionner par compression lors d’un déplacement de la bobine par rapport au corps selon l’axe longitudinal.
