Abstract

L’invention concerne un procédé de contrôle des vibrations pouvant produire divers effets vibratoires, et un dispositif associé. Plusieurs dispositifs vibrants sont dispersés à l'intérieur d'un appareil électronique portatif. Lorsque des vibrations se propagent le long d'un trajet et que l'on désire que cette propagation s'effectue dans un espace virtuel de l'appareil électronique portatif, l'organe de commande prend le contrôle de l'excitateur et amène celui-ci à appliquer séquentiellement une tension de commande sur les dispositifs vibrants rencontrés, dans l'ordre où les rencontres ont lieu, si bien que les dispositifs vibrants sont excités en séquence à des moments prévus. Cet arrangement crée un effet comme si les vibrations se propageaient le long du trajet, dans l'appareil électronique, du fait de la somme des vecteurs des forces vibratoires générées par les dispositifs vibrants. Le mouvement des vibrations peut prendre divers trajets, tels qu'un trajet rectiligne, un trajet dans le sens des aiguilles d'une montre, un trajet en sens inverse des aiguilles d'une montre, un trajet en zigzag ou en diagonale.
