Abstract

Le but de la présente invention est de réaliser un dispositif montrant des sensations tactiles au moyen duquel il est possible d'ajuster la fréquence d'une plaque d'oscillation. L'invention concerne un dispositif montrant des sensations tactiles et comprenant un film, une plaque d'oscillation, une unité de détection de toucher et une unité d'ativation. Le film se déforme dans la direction planaire par une tension électrique appliquée sur celui-ci. La plaque d'oscillation est reliée au film et fléchit dans la direction perpendiculaire en raison de la déformation du film dans la direction planaire. L'unité de détection de toucher détecte une opération tactile effectuée sur la plaque d'oscillation. Lorsqu'une opération tactile a été détectée par l'unité de détection de toucher, l'unité d'activation communique un signal d'activation au film. Des parties d'enfoncement qui sont enfoncées dans la direction perpendiculaire ou des parties saillantes qui font saillie dans la direction perpendiculaire sont formées sur la plaque d'oscillation.
