PURPOSE: A speaker diaphragm and a manufacturing method thereof are provided to satisfy a high elasticity and a high internal loss rate. CONSTITUTION: A speaker diaphragm is a part of a web(30) formed from electro-spinning fibers, and includes a web internal layer(31) maintaining a fibrous shape and a heat transformation layer(32) thermally deformed and formed in one side of the web internal layer. The web internal layer has an internal loss rate higher than the web heat transformation layer, and the web heat transformation layer has an elastic rate higher than the web internal layer. |
