| Zusammenfassung: | An object of the present invention is to provide a speaker diaphragm in which anisotropy can be readily controlled. A speaker diaphragm according to one aspect of the present invention contains a first polymer and a second polymer, wherein the first polymer and the second polymer undergo phase separation, the first polymer is a polyolefin and the second polymer is a thermoplastic resin being immiscible with the polyolefin, and one of either the polyolefin or the thermoplastic resin constitutes a sea phase 1a, and another one of either the polyolefin or the thermoplastic resin constitutes island phases 1b being interspersed in the sea phase 1a. |
