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.

摘要： Disclosed is an actuator that realizes reciprocal rotational motion of an electric toothbrush, for example, without utilizing a drive transmission mechanism that is separate from the drive source. In the actuator, a fixed body (120) has a coil (128) that is disposed around a magnet (160) and faces the magnetic planes with different polarities within the magnet (160) at individual prescribed distances, and an outer yoke (150) that covers the outer periphery of the coil (128). The fixed body (120) rotatably supports a movable body (110), which holds the magnet (160), via a coil spring that is an elastic member (130) made from a wire. An alternating current supplying part (140) supplies an alternating current having roughly the same resonance frequency as that of the fixed body (120) to the coil (128) to cause the movable body (110) to vibrate in a reciprocal rotational motion. The coil spring that is the elastic member (130) uniformly disperses stress generated by the vibration.

摘要： A vibration actuator includes: a fixing body including a base part and a magnetic suction force generation part including a core on which a coil is wound; a movable body including a presentation part connecting part connectable to a vibration presentation part, and a suction part composed of a magnetic material; and a first elastic support part and a second elastic support part, the first elastic support part and the second elastic support part being configured to elastically support the movable body. A suction force of the magnetic suction force generation part is generated by energization to the coil, and a vibration along the base extending direction is applied to the vibration presentation part through the movable body.

摘要： An actuator has: an affixed section having a coil; a first mobile section that is elastically held and disposed so as to allow movement in the axial direction inside one end of the coil, and has a first magnet magnetized in the axial direction of the coil and disposed on one end in the axial direction; and a second mobile section that is elastically held and disposed so as to allow movement in the axial direction inside another end of the coil, and has a second magnet magnetized in the axial direction and disposed on the other end in the axial direction. The first and second magnets are disposed such that identical magnetic poles are in the same direction in the axial direction, and the first and second mobile sections move in opposite directions along the same axis when a current is applied to the coil.

摘要： The purpose of the present invention is to provide a vibratory actuator the size of which can be reduced and which effectively produces vibrations felt by a user. The vibratory actuator has: a stationary body which has a curved surface section curved in a concave shape to be placed along the skin; and a movable body which is disposed on the curved surface section so as to be able to move with respect to the stationary body in a reciprocating manner along the curved surface section, thereby imparting a vibratory stimulus caused by the reciprocating motion to mechanoreceptors in the skin tissue via the curved surface section.

摘要： The purpose of the present invention is to provide an actuator that has a simple configuration and can stably achieve high output without the occurrence of magnetic saturation. This actuator has: a movable body provided with a cylindrical magnet section having alternately N-pole faces and S-pole faces on the peripheral surface surrounding a rotation shaft; and a fixed body provided with, pole tooth surfaces of the same number as the N-pole faces and the S-pole faces, and a coil that excites the pole tooth sections. The movable body has as a turning reference position a position at which the center of the pole tooth surfaces in the circumferential direction and the switching position of the pole faces of the magnet section face each other, and is held to the fixed body so as to be turnable back and forth around the rotation shaft in the circumferential direction.
