Manufacturing method of a speaker vibrating diaphragm by controlling a ratio of fiber materials

A manufacturing method of a speaker vibrating diaphragm by controlling a ratio of fiber materials, the method comprising the steps of:

• (A) fabric provision:
• providing a fabric interwoven by a plurality of warps and a plurality of wefts, the warps composed by sequentially and alternatively arranging a plurality of double-stranded first yarns, a plurality of single-stranded second yarns, a plurality of double-stranded third yarns, a plurality of single-stranded fourth yarns and a plurality of double-stranded fifth yarns, the wefts composed by sequentially and alternatively arranging a plurality of double-stranded first yarns, a plurality of single-stranded second yarns, a plurality of double-stranded third yarns, a plurality of single-stranded fourth yarns and a plurality of double-stranded fifth yarns, each of the double-stranded first yarns composed of 50% first fiber and 50% second fiber, each of the single-stranded second yarns composed of 100% first fiber, each of the double-stranded third yarns composed of 50% third fiber and 50% first fiber, each of the single-stranded fourth yarns composed of 100% second fiber, and each of the double-stranded fifth yarns composed of 50% third fiber and 50% fourth fiber;
• (B) impregnation:
• impregnating the fabric in a resin solution;
• (C) drying:
• drying the fabric impregnated with resin solution;
• (D) formation:
• pressing the dried resin-impregnating fabric to form a predetermined shape;
• and
• (E) cutting:
• cutting the formed speaker vibrating diaphragm from the fabric fiber.
