RECIPROCATING VIBRATION GENERATOR

摘要

PROBLEM TO BE SOLVED: To provide a reciprocating vibration generator having thin structure and providing strong vibration force, without arranging a weight escaping hole at a bottom lid. SOLUTION: The reciprocating vibration generator is provided with a cylindrical casing body 10 supporting a plate spring 30 suspending a weight 20 in a hollow part; a permanent magnet 60 attached to the lower side of the weight 20; and a bottom lid 80 on which a hollow toroidal coil 70 for reciprocatingly vibrating the weight 20 in a vertically retractable and advanceable fashion by magnetically attracting or repulsing the permanent magnet 60 is placed and which closes the lower opening of the casing body 10. A viscoelastic plate 100 is attached to the lower side part of the weight 20 as a collision buffering material. COPYRIGHT: (C)2007,JPO&INPIT
