PROBLEM TO BE SOLVED: To provide a manufacturing method for a vibration cone by which there is no need to unify a vibration cone with a voice coil using an adhesive, and manufacturing is easy, and shape-holding performance is high because is performed using an upper mold and a lower mold, and a drive plane of the vibration cone can be increased and a thinner product can be manufactured by the adoption of a flat type for the voice coil, and to provide a vibration cone manufactured by the method and a speaker using the vibration cone.;SOLUTION: At least either of a pair of molding blocks composed of an upper mold 1B and a lower mold 1A is formed of a material into which ultraviolet rays and/or visible rays 7 penetrate. Then, a predetermined amount of resin 4 to be hardened by the ultraviolet rays and/or visible rays 7 is dropped and molding blocks are closed after a voice coil 2 is arranged at a predetermined position on the female mold 1A having a surface formed almost in a vibration cone shape. The ultraviolet rays and/or visible rays 7 are irradiated from the outside of a mold which is penetrated with the ultraviolet rays and/or visible rays 7, and the resin 4 is hardened to form a vibration cone 8. The voice coil 2 is arranged on the female mold 1A along the vibration cone shape to attain a thinner product.;COPYRIGHT: (C)2006,JPO&NCIPI
