Vibration device

Abstract

A vibration device, which can generate impressing vibrations and is not easily broken even when a large impact of a drop, etc. is exerted, is provided. A gun-shaped controller 30 includes a barrel 32 and a barrel jacket 34 formed integral and a receiver 36 to a grip 38 are formed integral. A trigger 37 is provided on the underside of the receiver 36 . Inside the grip 38 of the gun-shaped controller 30 , 2 vibration actuators 40 A, 40 B are mounted, opposed to each other. Actual shooting sounds are applied to the vibration actuators 40 A, 40 B to thereby realize realistic vibrations of shooting. The vibration actuators 40 A, 40 B each includes a coil and a magnet. The coils are secured to the case members, the magnets are swingably mounted on the case members 38 , and the movements of the vibrating magnets are restricted by restricting members.

       6 . A vibration device comprising a vibration actuator including a case, at least a coil and a magnet, and a damper interconnecting the coil and the magnet with the magnet being movable relatively to the coil,
 the vibration actuator including the coil secured to the inside of the case so that when alternate current is flowed through the coil, the magnet reciprocates in the direction normal to the inside of the case, and   the vibration actuator comprising:   a first resting part for restricting the reciprocation of the magnet provided at a position which is away from the magnet by a first distance in the reciprocation directions of the magnet, which is away from the inside of the case with the coil secured to; and   a second restricting part for restricting the movement normal to the reciprocation direction of the magnet provided at a position which is away from by a second distance from the magnet in the direction normal to the reciprocation direction of the magnet,   wherein the first distance is a distance larger than a distance over which the magnet reciprocates when alternate current is flowed through at least the coil.
