Title:
SUPPORT FOR VIBRATION PICKUP IN VIBRATION EXCITER
Document Type and Number:
Japanese Patent JP3679886
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a support for the vibration pickup in a vibration exciter in which a vibration-proof base is substantially insusceptible to reaction force to the vibration of a vibrator, i.e., a movable body.
SOLUTION: The support for the vibration pickup in a vibration exciter comprises a pole structure 41 movable relatively to a vibration-proof base 30, a pole structure reset means 35, e.g. a leaf spring, for resetting the pole structure 41 to a neutral position with respect to the vibration-proof base 30, a movable body 38 having a movable coil 39 and vibrating with respect to the pole structure 41 and the vibration-proof base 30 through magnetic action between a pole 32 and the movable coil 39 while supporting the vibration pickup 10, a movable body supporting part 36 disposed on the vibration-proof base 30 while being separated from the pole structure 41 and supporting the movable body 38 relatively movably such that the acting line of the combined force of reaction force to the vibration of the movable body 38 substantially passes through the center of gravity of the pole structure 41, and means for resetting the movable body 38 to a neutral position with respect to the movable body supporting part 36.
