<P>PROBLEM TO BE SOLVED: To improve responsibility of tactile feedback. <P>SOLUTION: A detection circuit 108 generates a detection signal S1 at an oscillation frequency when a touch to a touch sensor 100 is detected. A tactile circuit 110 vibrates a piezoelectric actuator 116 by generating a drive signal S2 at a drive frequency. The tactile circuit 110 directly generates the drive signal S2 from the detection signal S1 by converting the detection signal S1 into the drive signal S2. When the oscillation frequency is higher than the drive frequency, the tactile circuit generates the drive frequency by reducing the oscillation frequency. <P>COPYRIGHT: (C)2012,JPO&INPIT |
