<P>PROBLEM TO BE SOLVED: To provide a vibration device which can prevent a derivation process of an AC current (AC voltage) supplied to a coil from being complicated. <P>SOLUTION: The linear motor (vibration device) includes the coil, a movable part which reciprocates by a magnetic field generated by the coil, a housing that accommodates the movable part and vibrates by the reciprocation of the movable part, and a spring part provided between the movable part and the housing. Moreover, the voltage of the waveform having a shape that projects to a positive side is applied to the coil. <P>COPYRIGHT: (C)2012,JPO&INPIT |
