WIPO Patent Application WO/2016/075775
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an electronic device capable of imparting a variety of suitable tactile sensations. The electronic device includes: a top panel having an operation surface on a surface side thereof; a coordinate detecting part for detecting the coordinates of an operation input executed on the operation surface; a housing installed on the rear surface side of the top panel; a first vibration element installed on the top panel; a support for supporting the top panel on the housing, wherein the support is capable of switching the supporting stiffness of the top panel relative to the housing to a first level and a second level that is less than the first level; and a control part for setting the supporting stiffness of the support to the first level when the first vibration element is driven with a first driving signal that generates, on the operation surface, a characteristic vibration in an ultrasonic wave band and for setting the supporting stiffness of the support at the second level when the first vibration element is driven with a second driving signal that generates, on the operation surface, a vibration in an audible band.
