Abstract

L'invention concerne un dispositif d'entraînement dans lequel les actionneurs piézo-électriques (4) sont entraînés par un circuit oscillant. Les actionneurs (4) forment, avec les éléments d'entraînement mécaniques qu'ils entraînent, un premier système ressort-masse qu'ils font vibrer dans une première fréquence de résonance. Les éléments d'entraînement entraînent un second système ressort-masse (1, 2) ayant une seconde fréquence de résonance, inférieure à la première. La seconde fréquence de résonance détermine une enveloppante de même fréquence, durant laquelle les actionneurs (4) de la première fréquence sont entraînés. Les actionneurs piézo-électriques (4) sont mis en circuit quand la masse (1) du second système ressort-masse (1, 2) entre en contact mécanique avec les éléments d'entraînement du second système.
