Patent ID: 7663604

Claim:
An input device, comprising: a support frame; a touch panel configured to receive an input operation of information by a pressure exerted on the touch panel; a vibration generation device configured to generate various forms of vibrations, in accordance with the information, through the touch panel; a plurality of tapered projections constructed to contact a face of the touch panel closest to the support frame and to contact the vibration generation device; a touch panel support member constructed to contact the touch panel and the support frame and to extend farther from the touch panel to the support frame than a face of the vibration generation device farthest from the touch panel extends to the support frame; and a vibration control circuit configured to control the vibration generation device to generate the various forms of vibrations in accordance with the information, the vibration generation device being a bimorph piezoelectric actuator including a first actuator unit and a second actuator unit stacked on the first actuator unit in which when one of the first actuator unit and the second actuator unit expands, an other of the first actuator unit and the second actuator unit contracts, each of the first actuator unit and the second actuator unit having a multi-layered piezoelectric element layer.
