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： 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： An actuator includes a movable body including a cylindrical magnet portion, an immovable body including pole tooth faces and a coil, and a torsion coil spring supporting a movable body to the immovable body. The coil receives an alternating current of a frequency substantially equal to a resonance frequency of the movable body and excites the pole tooth faces to have alternately different polarities in the circumferential direction. One end of the torsion coil spring is fixed to one end of a rotary shaft of the movable body and other end is fixed to the immovable body. The torsion direction of the torsion coil spring is arranged to be coaxial with the rotary shaft. The torsion coil spring supports the movable body to enable the movable body to vibrate at the resonance frequency of the movable body.
