A method of manufacturing a speaker diaphragm fabric for a loudspeaker, includes: a preparation step, a plurality of first warps, at least one second warp and a plurality of wefts are prepared, wherein the second warp has characteristics different from the first warps; and a weaving step: the plurality of the first warps and the second warps are aligned and the wefts transversely cross and pass alternately over and under each of the first warps and the second warps in order to form the speaker diaphragm fabric having at least one formation region and a non-formation region exterior to the formation region. The second warps made from an inferior material are provided at the non-formation region, thereby reducing the waste cost and facilitating the differentiation of the formation region and the non-formation region.
A speaker diaphragm fabric, woven by a plurality of first warps, at least one second warp, and a plurality of wefts, having at least one formation region and at least one non-formation region exterior to said at least one formation region, wherein each of said at least one formation region has a plurality of said first warps crossing a plurality of said wefts transversely therein for forming a speaker diaphragm, said at least one non-formation region has some of said at least one second warp crossing some of said wefts transversely therein, said at least one second warp has at least one characteristic different from said first warps, and none of said at least one second warp is in any of said at least one formation region.
A speaker diaphragm fabric, woven by a plurality of first warps, at least one second warp, and a plurality of wefts, having a first formation region and a second formation region aligned on a row, wherein said at least one second warp has at least one characteristic different from said first warps and is provided at a non-formation region exterior to said first and second formation regions, one distal end of said at least one second warp is spliced with one of said first warps, said first formation region has a dimension greater than said second formation region, and said at least one second warp is provided at said non-formation region on one side of said second formation region on said row while the first warp spliced with said at least one second warp is provided on said row and is extending through said first formation region.
