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： In the movable body one of a magnet and a core that has a magnetic pole surface disposed so as to face a magnetic pole surface of the magnet via an air gap and around which a coil is wound is provided on each of both sides across the shaft of the support shaft part in the movable body, and in the fixing body the other is provided facing the magnet or core disposed on both sides of the shaft of the support shaft part in the movable body. The movable body is elastically supported by magnetic attractive force generated between the magnetic pole surfaces at each of both sides across the shaft and vibrates back and forth in the direction of the shaft of the support shaft part with respect to the fixing body by the coil interacting with the magnet.

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： 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.

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： A fixing body includes a coil holding part that is disposed to surround a magnet externally in a radial direction and holds the coil disposed outside the bobbin-shaped coil holding part in the radial direction. The coil holding part includes a coil protection wall portion that is disposed inside the coil in the radial direction of the coil with a gap being interposed between the coil protection wall portion and the magnet, and inhibits contact between the coil and the movable body. Elastic supporting parts are a plurality of leaf springs installed between the fixing body and the movable body to sandwich the movable body in the vibration direction, and support the movable body such that, in a non-vibration state and in a vibration state of the movable body, the movable body is freely movable in the vibration direction without making contact with the coil holding part.
