Abstract

Le présent module de vibration comprend un panneau tactile à surface incurvée, une unité de support ayant une unité de connexion à une extrémité et supportant le panneau tactile à surface incurvée par l'intermédiaire de l'unité de connexion, et une unité de vibration qui fait vibrer le panneau tactile à surface incurvée. L'unité de support supporte le panneau tactile à surface incurvée de manière à permettre à l'unité de connexion d'être déplacée dans la direction de la longueur de corde de l'écran tactile à surface incurvée.
