A vibration actuator according to the present invention comprises a plate that is a magnetic body, an electromagnet that is provided on the plate and is formed by providing a coil to a center part of a core, and an elastic body that supports the core on both sides of the coil and is connected to the plate. Magnetic force generated by energization of the coil causes one of the coil or the plate to be displaced toward the other and vibrate.

Vibration actuator with elastic body with rectangualr frame body surrounding the plate and contact-type input device

Provided is a vibration actuator including: a movable body including a magnet having a pillar shape; and a fixing body including a coil and a main body part. The main body part includes an inner peripheral surface, which surrounds the movable body with a gap between the inner peripheral surface and an outer peripheral surface of the movable body inside the coil, and supports the movable body via an elastic support part such that the movable body is vibratable in an axial direction of the movable body. The vibration actuator is configured to cause a flow of a fluid in a direction opposite to a direction of movement of the movable body in the gap and to generate a pipe resistance to the fluid.
