摘要：
A speaker diaphragm made of a resin containing a thermoplastic polymeric material is provided. The speaker diaphragm includes a changed portion formed on the diaphragm that is molded using the resin. The changed portion is formed by partially changing physical properties of the thermoplastic polymeric material for dispersing local vibrations based on a characteristic of local vibrations measured in advance.
