Abstract:
A vibration actuator includes: a movable part including a coil or a magnet; a fixing part including the other one of the coil or the magnet; and an elastic supporting part supporting the movable part such that the movable part is movable to the fixing part. The movable part reciprocates with respect to the fixing part in a vibrating direction by interaction between the coil and the magnet. The magnet is disposed to be radially inwardly spaced apart from the coil. The elastic supporting part is fixed at its one end to the fixing part and at its other end to the movable part. The elastic supporting part has a structure for cantilevering the movable part. The coil in a state of being fixed to a resin coil holder is integrated in the movable part or the fixing part.
