    摘要: A speaker diaphragm which has a high rigidity and can improve sound transmission speed for better sound quality is provided. The speaker diaphragm contains fibers of 3 to 50 mm length mixed in matrix resin. The fibers are oriented radially from center to periphery in surface layers of the diaphragm, while they are oriented in different directions in a middle layer. After setting the resin, these fibers are fixed in the matrix resin with certain tension applied thereto.

    摘要: A diaphragm for a speaker is made by forming acrylic foam. As the material of the acrylic foam, using maleic anhydride and methacrylic amide are contained. Thereby, the coefficient of saturated water absorption can be reduced. When the diaphragm thus manufactured is used for a speaker device, the decrease of strength due to the water absorption and the deterioration of the sound quality can be prevented even in a humid environment.
