Note that a gap that allows displacement of the touch panel 400 in the thickness direction is secured between the touch panel 400 and the display monitor 100. For this reason, when the piezoelectric element 420 vibrates, the displacement of the touch panel 400 in the thickness direction accompanying the vibration is possible.

Abstract

L'invention concerne un dispositif électronique qui réduit autant que possible le risque que de l'eau ou de la poussière entre dans le dispositif électronique sans affaiblir la vibration d'un écran tactile. Ce dispositif électronique comprend un écran tactile (21), des unités de vibration disposées sur l'écran tactile (21) pour une vibration de flexion dudit écran tactile (21), et un élément de support (24) qui supporte l'écran tactile (21), le corps de cadre supérieur (l'élément de support) (24) étant configuré à partir d'au moins deux parties de dureté différente, une partie dure (24a) et une partie molle (24b), et le bord (21a) de l'écran tactile (21) qui est disposé le long de la surface vibrante de vibration de flexion est joint à la partie molle (24b).
