摘要
A speaker diaphragm molded from a poly-bisphenol phthalate type plastic film having ester linkages prepared from an aromatic dicarboxylic acid such as isophthalic acid or terephthalic acid or a mixture thereof and a bifunctional phenol such as bisphenol A. This speaker diaphragm has an excellent low-pitched sound reproducing performance and is further featured by the flat acoustic pressure- frequency characteristic and improved transduce efficiency.
