Abstract:
A vibration presentation device includes: an electrostatic or piezoelectric actuator; a first elastic body laminated on the actuator; a second elastic body laminated on the actuator on the opposite side to the first elastic body; an electrostatic or piezoelectric sensor disposed around the actuator; a cover that holds the first elastic body and the second elastic body such that the first elastic body and the second elastic body are compressed more than the actuator, the cover transmitting, when a pressing force in the laminate direction is applied to the cover from the outside, the pressing force to a sensor, and vibrating by vibration generated by the actuator; and a control device that drives the actuator when the sensor detects the pressing force.
