PROBLEM TO BE SOLVED: To make a module slender and small in size by a method in which an oscillation module set in portable equipment which tells reception, timer information, etc., to a user is composed of a rectangular oscillating weight in which a magnet and a weight are integrated, and a driving coil which reciprocates the oscillating weight in cooperation with a spring, etc. SOLUTION: A weight 7 and a magnet 6 are integrated by an adhesive so that the magnetism of both is of the same pole in the outside to constitute an oscillating weight. A coil 4 is wound square, placed in a frame 3, and integrated with the frame 3 by an adhesive, etc. Both ends of a spring 5 are fixed to the frame 3 by caulking, fusion bonding, adhesion, etc., the middle part of the spring 5 is connected with the oscillating weight by a fixing pin 8, a member which is integrated with the frame 3 is inserted into a housing 2, and the housing 2 is covered by a lid 1. By applying an electric current, etc., to the coil to generate oscillation, the oscillating weight with a large mass is oscillated in linear reciprocating motion, the oscillation is transmitted to the housing 2 and the lid 1, and the whole oscillation generator is oscillated. |
