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(10) includes a macromolecular film(20) attached to both sides of web; and a web(30), which is a web formed from an electro-spinning fiber, attached to the macromolecular film and having at least one of a relatively high internal loss rate and a relatively low density in comparison with the macromolecular film. |
