PURPOSE:To improve the bonding performance of a resin and a reinforcing member by using a constituent subject to composite by a polymer having an opposite electric charge to a surface electric charge of an organic or inorganic solid substance. CONSTITUTION:The speaker diaphragm is formed by using the constituent subject to composite strongly by the polymer having an opposite electric charge to a surface electric charge of the organic or inorganic solid in the liquid medium. The inexpensive and stable composite is obtained, the bonding performance between the resin and the reinforcing member is improved and a high specific elastic rate E/rho and a proper internal loss are realized. |
