<p><P>PROBLEM TO BE SOLVED: To provide a tactile sense feedback function and an acoustic feedback function, and to achieve size reduction and power saving. <P>SOLUTION: This touch panel type input device with a touch panel 2 for detecting contact at a position corresponding to the display position of an image displayed on a display device, and for generating an input signal includes a piezoelectric actuator 6 to be driven in a vertical direction to a plane-shaped touch panel 2 for giving vibration to the touch panel 2; a digital signal processor 4 for outputting at least either an acoustic signal or a tactile sense signal as a driving signal based on the input signal generated by the touch panel 2; and a D class amplifier 5 for driving the piezoelectric actuator 6 based on the driving signal output from the digital signal processor 4. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
