DYNAMIC TYPE VIBRATION GENERATOR
Document Type and Number:
Japanese Patent JP3764748
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To reduce the mass of a member for connecting a moving coil and a vibration exciting base to reduce exciting force required for obtaining prescribed acceleration and to miniaturize a vibration generator to attain the cost reduction.
SOLUTION: In dynamic type vibration generator A in which an alternating current is fed to a moving coil 11 arranged in a magnetic field by a permanent magnet or an exciting coil 6 to obtain exciting force, a slit 13 extending in the vibration direction of the moving coil 11 is formed in a shell part 1 of the vibration generator, also an extending member 15 extending to the outside in the direction crossing perpendicularly to the vibration direction thereof and through the slit 13 is connected to the moving coil 11 and an exciting base 17 for mounting a material to be vibrated is provided at the outer extended end of the extending member 15. Moreover, a guide rail 18 extending along the longitudinal direction thereof is arranged in the slit 13, and also rollers 20 rolling on the guide rail 18 is freely rotatably fitted to the extending member 15.
