Classification: CPC G  B | IPC G

Claim 0:
1. An operation device comprising:
a movable part having an operating surface on which a contact operation is performed by an living body;
a vibration exciter attached to the movable part at a position other than the operating surface, and configured to excite the movable part in a first direction along the operating surface, and in a second direction intersecting the operating surface;
a base part;
an elastic support, provided between the movable part and the base part, and configured to elastically support the movable part with respect to the base part; and
a controller configured to drive the vibration exciter so that the vibration exciter excites the movable part along the first direction to provide a tactile sensation to the living body performing the contact operation, and to drive the vibration exciter so that the vibration exciter excites the movable part along the second direction to generate the sound from the operating surface, wherein
the movable part provides a tactile sensation to the living body making the contact operation when excited in the first direction by the vibration exciter, and generates a sound from the operating surface when excited in the second direction by the vibration exciter,
the controller is configured to drive the vibration exciter, so as to excite the movable part at a first frequency along the first direction, and to excite the movable part along the second direction at a second frequency higher than the first frequency, and
the elastic support elastically supports the movable part so that a second natural frequency of the movable part in the second direction is greater than a first natural frequency of the movable part in the first direction.
