Abstract
A diaphragm for tweeter is made of loosened and arbitrarily oriented carbon fiber pieces, or a mixture of such loosened and arbitrarily oriented carbon fiber pieces and a predetermined amount of organic or inorganic fibers, which are processed to form a paper-like or non-woven fabric-like thin sheet having a final thickness from about 0.02 mm to about 0.15 mm. The diaphragm so produced has increased structural strength to resist humidity and insect-biting, and a sufficient rigidity and very small thickness to produce clear and soft sound quality.
Claims6
A diaphragm for tweeter, comprising a plurality of loosened and arbitrarily oriented carbon fiber pieces, which are obtained by cutting carbon fibers into pieces, and then loosening and separating said carbon fiber pieces, so that said carbon fiber pieces looked like loose yarns;
- and said loosened and arbitrarily oriented carbon fiber pieces being processed to form a paper-like thin sheet, which is subjected to further processing to reduce a thickness thereof and form a predetermined shape.
