Abstract:
1. A touch-panel input device having a function for providing vibrations, the device comprising: a touch panel for receiving an operation on an operation item displayed on a display panel; an operation detector for detecting an operation on the touch panel; and a vibration-controlling unit for vibrating the touch panel for providing force feedback upon detecting an operation on the touch panel and for vibrating the touch panel so as to produce sounds; wherein the sounds produced by vibrating the touch panel are generated from audio signals supplied by a sound source, the volume of sounds produced by vibrating the touch panel is adjustable by an operator, and when the magnitude of vibrations for producing the sounds is greater than the magnitude of vibrations for force feedback, the vibration-controlling unit controls the magnitude of vibrations so that the magnitude of vibrations for producing the sounds is less than the magnitude of vibrations for force feedback in response to a touch of the operator on the touch panel while the touch panel vibrates to produce the sounds, upon detecting an operation on the touch panel by the operation detector.
