Abstract
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.
