Abstract
A sensory vibration generation apparatus includes an electromagnetic actuator that includes: a plate-shaped base part on which an electromagnet consisting of a core and a coil is arranged, a movable body including a magnetic yoke disposed opposite the electromagnet with a gap and the movable body having a shape that allows a portion of the coil to be inserted at a position opposite to the coil, and an elastic body connected to each of the plate-shaped base part and the movable body so that the plate-shaped base part and the magnetic yoke are displaced relative to each other by energizing the electromagnet, wherein the electromagnetic actuator vibrates in one direction of a vibration direction with an input driving signal to the coil. The apparatus further includes a rectifier configured to acquire the driving signal by performing half-wave rectification on an alternating current signal.
