Abstract

Un dispositif électronique est divulgué. Le dispositif électronique peut délivrer une première vibration à l'aide d'un moteur de vibration lorsqu'un événement d'occurrence de vibration est détecté pendant que le dispositif électronique est dans un état plié, et délivrer une seconde vibration ayant une fréquence comprise dans une bande de fréquence de résonance du moteur de vibration à l'aide d'un haut-parleur positionné dans un boîtier différent d'un boîtier dans lequel le moteur de vibration est positionné.
