PROBLEM TO BE SOLVED: To provide a speaker vibration cone in which distortion is reduced by eliminating friction, slip, and the like, between fibers and deterioration due to UV-rays is eliminated and has no effect on sound quality. SOLUTION: Textile fabrics made of polyester fibers coated with polyester having a melting point of 120-180°C is hot pressed to produce the speaker vibration cone wherein the diameter of the polyester fiber is preferably in the range of 10-100μm. Average thickness of polyester coating for the polyester fiber is preferably in the range of 0.5-5μm. Weaving density of the textile fabrics is preferably in the range of (100 to 2,000)×(100 to 2,000) fibers/inch and the surface density is preferably in the range of 10-200 g/m<SP>2</SP>.
