Abstract

To provide a tactile vibration applying device that efficiently outputs vibrations using an electrostatic or piezoelectric actuator. The tactile vibration applying device includes the electrostatic or piezoelectric actuator formed in a flat shape, and expanding and contracting in a thickness direction, a first elastic body having an elastic modulus smaller than an elastic modulus of the actuator in the thickness direction and disposed to contact a surface of the actuator on a side of the first electrode, and a first cover covering a surface of the first elastic body opposite to a surface of the first elastic body contacting the actuator, pressing the actuator and the first elastic body in the thickness direction of the actuator, and holding the first elastic body in a state that the first elastic body is compressed more than the actuator.

Dependent claims

A tactile vibration applying device comprising:

an electrostatic or piezoelectric actuator formed in a flat shape, having a first electrode and a second electrode opposing to each other in a thickness direction, and expanding and contracting at least in the thickness direction;
a first elastic body having an elastic modulus smaller than an elastic modulus of the electrostatic or piezoelectric actuator in the thickness direction, and disposed in contact with a surface of the electrostatic or piezoelectric actuator on a side of the first electrode;
and
a first cover covering a surface of the first elastic body opposite to a surface of the first elastic body contacting the electrostatic or piezoelectric actuator, pressing the electrostatic or piezoelectric actuator and the first elastic body in the thickness direction of the electrostatic or piezoelectric actuator, and holding the first elastic body in a state that the first elastic body is compressed more than the electrostatic or piezoelectric actuator.
