Bodily vibration generation device and bodily vibration presentation apparatus

A sensory vibration generation apparatus comprising:

• 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;
• an alternating current signal input section to which an alternating current signal is input;
• and
• a rectifier configured to acquire the driving signal by performing half-wave rectification on the alternating current signal and output the driving signal to the electromagnetic actuator.
