Thin solenoid coil of a power generating structure and its manufacturing method

The present invention discloses a thin solenoid coil of a power generating structure, which includes a base, a plurality of elastomers, a moveable object, a magnetic unit and a magnet-conductive metal iron sheet. The base has an upper bottom part arranged thereon a first recessed slot installed therein the plurality of elastomers. A second recessed slot is arranged on the front side and the rear side of the base and the magnet unit is installed in the second recessed slot. A third recessed slot is arranged on the moveable object for fixing to the top of the plurality of elastomers, wherein an electricity-conductive unit is placed in a slot of the moveable object. When the moveable object is pressed by external force to move, the pluralities of elastomers are compressed to allow the electricity-conductive unit to pass through the magnetic unit. When the external force pressed on the moveable object is released, the elastic force of the elastomers resumes the electricity-conductive unit. Therefore, the electric
