摘要： This actuator has a stationary body having either a coil or a magnet, a movable body having the other, that is, a magnet or a coil, and an elastic body that supports the movable body so as to be capable of moving with respect to the stationary body. The movable body moves reciprocally with respect to the stationary body in the vibration direction due to concerted movement of the magnet and the energized coil. The magnet can advance into and separate from the interior of the coil in the vibration direction. The elastic body is a plate-shaped elastic body one end of which is secured to a stationary unit, the other end of which is secured to the movable body, and which supports the movable body with a cantilever structure so as to be capable of oscillating reciprocally in the vibration direction.

摘要： An actuator allows miniaturization by realizing back-and-forth rotating motion of, for example, an electric brush without a drive transmitting mechanism which is a separate entity from a drive source. In a movable body (110) of this actuator (100), an outer yoke (150) is provided with sidewalls (152 and 153) located opposing each other spaced a predetermined interval apart. A magnet (160) is provided in the outer yoke (150) through a non-magnetic body (170) and has different magnetic poles located opposing to the opposing inner wall planes of the outer yoke (150) through the air gaps. The movable body (110) is provided with a shaft (180). The fixed body (120) has a coil (128) which is located in the air gaps and which circles the magnet (160). The fixed body (120) movably supports the movable body (110) through elastic bodies (130). An alternating current supplying section (140) supplies to the coil (128) the alternating current of a frequency virtually equal to the resonance frequency of the movable body (110).

摘要： A vibration generator 1 has an attachment structure of a spring by which the attachment error of the spring elastically supporting a mover composed of a magnet and a yoke does not become the error of the span of the spring to make it possible to improve the ease and yield of manufacture. The vibration generator 1 includes a mover which is composed of a magnet 5 and yokes 4, 7a and 7b, and a spring 6 which is composed of an integrally molded article made of an elastomeric material and elastically supports the mover to allow the mover to vibrate in the central axis direction C. The spring is arranged on the outside of a coil 3 in a radial direction thereof and extends along the radial direction. An outer end portion 6a in the radial direction is nipped by two parts 2 and 8 in the central axis direction to be fixed to the housings 2 and 8, and an inner end portion 6b in the radial direction is nipped by two parts 7a and 7b constituting the outer circumferential part of the yoke in the central axis direction to be fixed to the outer circumferential part of the yoke. The outer end portion and the inner end portion have projecting parts formed to project from an elastic deformation section 6c, connecting the outer end portion and the inner end portion to each other, into two directions along the central axis.

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.
