Abstract

PURPOSE:To make light the weight and to make suitable the manufacture for mass-production, by incorporating a skin consisting of a plurality of consecutive cylindrical core members and thin films through the use of a nonwoven fabric thermal molten type adhesives. CONSTITUTION:A core member 1 constituting a diaphragm is formed to honey- comb shape where a number of hexagonal cylindrical unit cores 2 are adjacently arranged. On the front and rear side of the core 1, a paper foil shape thin film 3 manufactured in cone shape from natural fiber is sticked. Between the thin film 3 and the core 1, a polyamide resin nonwoven fabric thermo-molten adhesives 5 is inserted, and the core 1 and the thin film 3 are unified by melting and solidifying the adhesives 5.
