摘要： A vibration actuator includes: a movable part including a coil or a magnet; a fixing part including the other one of the coil or the 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 with respect to the fixing part in a vibrating direction by interaction between the coil and the magnet. 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. The coil in a state of being fixed to a resin coil holder is integrated in the movable part or the fixing part.

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： 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.

摘要： In a device cover fastened to a casing of a vibration generating source to cover a device mounted on an outer surface of the casing, an elastic member having a natural frequency different from that of the device cover, is mounted in a mounting bore provided in the device cover which is fastened directly to the casing to close the mounting bore. Thus, the strength and durability requirements of the device cover are satisfied and moreover, the vibration of the device cover can be inhibited to reduce the resonance sound from the device cover in a simple arrangement.
