Abstract
A method for manufacturing a speaker diaphragm comprising the steps of forming a plurality of virtual concentric circles between central point of a circle having a predetermined size and a circumference thereof; dividing said each concentric circle with a predetermined angle, forming divided points on the circumference of each concentric circle and arranging a plurality of yarns from a point on the circumference of said circle to another point thereof to come in tangential contact with said divided points, thereby forming a omnidirectional pseudo-textile fabric; thermosetting said pseudo-textile fabric; and removing a gap formed on said pseudo-textile fabric using a resin, a film or a sheet.
