Abstract

PURPOSE:To obtain a light-weight, high-stiffness, high-internal loss diaphragm for speaker, by using a sheet, which is obtained by mixing carbon fibers and so on as reinforcing material into the high-density polyethylene base materials, as surface materials of a core material to give a sandwich structure. CONSTITUTION:The sheet obtained by mixing carbon fibers, glass fibers, aramide fibers, and so on as reinforcing materials into the high-density polyethylene base material is used as surface materials 2 of one face, at least, of core material 1.
