Abstract

L'invention concerne un actionneur (1), dans lequel un circuit d'entraînement magnétique (6) fait vibrer un corps mobile (3) dans une deuxième direction (X) et une troisième direction (Y) à l'intérieur d'un corps de support (2). Le corps mobile (3) comporte un élément de sortie (30) qui s'étend vers un côté (Z1) dans une première direction (Z) et fait saillie vers l'extérieur à partir du corps de support (2) sur un côté (Z1) dans la première direction (Z), et permet à l'utilisateur de ressentir une vibration à travers une première partie en regard (32) de l'élément de sortie (30). Le corps mobile (3) comporte un palier (33) qui supporte une partie d'arbre (31) de l'élément de sortie (30) de façon à permettre un mouvement dans la première direction (Z), et entre la première partie en regard (32) du corps mobile (3) et une première surface externe (21) du corps de support (2), une première partie de support élastique (41) est prévue qui, dans un état sollicité dans lequel la première partie en regard (32) est sollicitée vers un côté (Z1) dans la première direction (Z), supporte la première partie en regard (32) de façon à pouvoir se déplacer dans la deuxième direction (X) et la troisième direction (Y).
