摘要： A vibration actuator includes: a fixing part including one of a coil and a magnet; a movable part including the other one of the coil and the magnet; and an elastic supporting part configured to support the movable part movably with respect to the fixing part. The movable part is configured to reciprocate with respect to the fixing part in a vibration direction through cooperation between the powered coil and the magnet. The magnet is disposed away from and radially inside the coil. The elastic supporting part has a plate-like shape in which one end of the elastic supporting part is fixed to the fixing part at the side of the movable part and the other end is fixed to the movable part, and cantilevers the movable part in such a manner that the movable part can reciprocate in the vibration direction.

摘要： 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.

摘要： A vibration actuator includes: a movable part including a coil; a fixing part including a 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 to the fixing part in a vibrating direction by interaction between the coil and the magnet. The magnet includes a first magnet and a second magnet joined to each other such that their magnetization directions are opposite to each other, and 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. At least one of the first and the second magnets includes a depressed portion in its joining surface.
