摘要： A vibration actuator has a movable body including: a disk-shaped magnet; disk-shaped cores fixed on front and rear surfaces of the magnet and each having an opening at a center thereof; leaf springs having a substantially circular shape; and spring stopper weight parts each having one end positioned by joining the opening to be joined with one of the cores and having another end connected to a central part of one of the leaf springs; and a fixing body including an annular coil having a larger inner diameter than the magnet, the cores and the spring stopper weight parts. The fixing body supports an outer periphery part of the leaf springs and accommodates therein the movable body such that the magnet, the cores and the spring stopper weight parts are capable of moving upwardly and downwardly inside the coil.

摘要： A vibration actuator includes a movable body provided with one of a coil and a magnet that is disposed radially inward of the coil with a gap formed therebetween, a fixing body provided with the other of the coil and the magnet and a shaft portion, and an elastic support portion, the movable body vibrating in a vibration direction by means of cooperation between the coil supplied with power and the magnet. The movable body is provided with a through-hole into which the shaft portion is inserted with a gap formed between the through-hole and an outer peripheral surface of the shaft portion and the elastic support portion supports the movable body such that the movable body does not come into contact with the shaft portion at a time when the movable body does not vibrate and at a time when the movable body vibrates.

摘要： A vibration apparatus, which is provided with vibration actuators with which a moving body elastically supported on a fixed body can be vibrated linearly with respect to the fixed body at a resonance frequency, has a mounting case in which multiple vibration actuators are mounted. The multiple vibration actuators oscillate at roughly the same resonance frequency, and in a manner such that the respective oscillation axis lines along the oscillation directions of the moving bodies are parallel to each other and that the center of gravity of the mounting case is interposed between the oscillation axis lines, the vibration actuators are disposed in orientations according to which the actuators excite oscillations in mutually opposite directions on the respective oscillation axis lines.

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： An oscillatory actuator has: a fixed body that has a planar part and a flat coil disposed on the planar part; and a movable body that has a magnet facing the coil and oscillates in a reciprocating manner in one direction relative to the fixed body above the planar part via cooperation between the coil and the magnet. The fixed body has a pair of linear bearings that are respectively disposed along both side surfaces extending in said one direction of the movable body and are equipped with balls capable of rolling and coming into contact with the respective side surfaces. The movable body is supported via the balls of the linear bearings so as to be able to oscillate in said one direction.
