Abstract
This vibration actuator comprises a fixed body including a coil, a movable body including a magnet, and an elastic support part that supports the movable body so as to be freely moveable with respect to the fixed body. The elastic support part has an outer circumferential part fixed to the fixed body, an inner circumferential part disposed inside in the radial direction of the outer circumferential part and fixed to the movable body, and a deforming arm part disposed between the outer circumferential part and the inner circumferential part and coupling the outer circumferential part and the inner circumferential part, the deforming arm part being elastically deformable. An attenuation part is provided across the outer circumferential part and a portion of the deforming arm part on an outer circumferential part side thereof, the attenuation part attenuating vibrations in the elastic support part when the movable body moves.
