Abstract
A vibration actuator includes a flat plate base part that accommodates a coil wound around a plate-shaped core in an internal opening; a plate-shaped body including a suction part made of a magnetic material, the plate-shaped body disposed to overlap the flat plate base part; and an elastic support part that arranges the suction part to face the plate-shaped core within the region of the internal opening and connects the plate-shaped body to the flat plate base part so as to be movable along a surface of the flat plate base part.
Claims7
A vibration actuator configured to apply a vibration to a connected vibration presentation part, the vibration actuator comprising:
- a flat plate part that accommodates a coil wound around a plate-shaped core in an internal opening;
- a plate-shaped body including a suction part made of a magnetic material, the plate-shaped body disposed to overlap the flat plate part;
- and
- an elastic support part that arranges the suction part to face the plate-shaped core within the region of the internal opening and connects the plate-shaped body to the flat plate part so as to be movable along a surface of the flat plate part;
- and
- wherein the plate-shaped body includes an opening in which the coil is disposed.
