<p><P>PROBLEM TO BE SOLVED: To provide an input device capable of providing a reliable operation sensation even when the type of an apparatus has proceeded toward downsizing. <P>SOLUTION: A sound signal (an sound signal-superimposed alternating signal) is provided through an amplifier from a sound source. Oscillating an excitation means 100 oscillates a panel 103 to generate a sound. In addition, when a signal from a depression detection means mounted on the panel 103 is transferred to a driving signal generating means, the driving signal generating means supplies the signal of a resonance frequency for the excitation means 100 to the excitation means 100. Providing the signal of the resonance frequency for the excitation means 100 generates a high oscillation to the excitation means 100, the reliable operation sensation can be given to an input person. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
