Abstract
This vibration actuator includes: a housing; a first movable part that has a magnet part and is disposed in such a manner as to be capable of reciprocating in a vibration direction that is along the axial direction, such reciprocation being within the housing and via a first elastic support part joined to both ends of the magnet part, the ends being separated in the axial direction of the magnet part; and a second movable part that has a coil part disposed to surround the magnet part, and that is disposed so as to be capable of reciprocating along the vibration direction at the outer periphery of the first movable part such reciprocation being within the housing and via a second elastic support part joined to both ends of the coil part, the ends being separated in the axial direction of the coil part.
