<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a speaker diaphragm with which an edge formed from a soft material can be stabilized with respect to chemicals while suppressing a change in acoustic characteristics, and a speaker diaphragm which is manufactured by the manufacturing method. <P>SOLUTION: On a surface of an edge 12 formed from a soft material in a speaker diaphragm 10, a coating 13 of an inorganic compound is formed according to chemical vapor deposition. The coating of the inorganic compound, which does not affect chemicals, is formed on the surface of the edge, thereby stabilizing the edge with respect to the chemicals while suppressing a change in product characteristics. Furthermore, since the coating is formed according to chemical vapor deposition, processing can be performed without any product characteristic change such as dissolution, swelling or deformation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
