Abstract:
A vibration actuator includes: a fixing body including a base part and a magnetic suction force generation part including a core on which a coil is wound; a movable body including a presentation part connecting part connectable to a vibration presentation part, and a suction part composed of a magnetic material; and a first elastic support part and a second elastic support part, the first elastic support part and the second elastic support part being configured to elastically support the movable body. A suction force of the magnetic suction force generation part is generated by energization to the coil, and a vibration along the base extending direction is applied to the vibration presentation part through the movable body.
