Abstract

PURPOSE:To reduce the specific gravity of diaphragm plate and to increase elastic factor and internal loss, by mixing hollow glass fiber as reinforce member, in a diaphragm plate for speaker taking thermosetting plastic as base material. CONSTITUTION:In a diaphragm plate for speaker taking thermosetting plastic as base material, hollow glass fiber is mixed as reinforce member. The hollow glass fiber is hollow glass fiber shown in a-g. Accordingly, the fiber is hollow, the specific gravity is low, specific elasticity and bending rigidity are greater. Further, since air layer is formed at the hollow section, the internal loss is made greater. Further, the fiber length of the glass fiber is 13mm. or less and outer diameter is 50mu or less, causing a good scattering property. Further, the effect as reinforce member is maximum at 60-75% of the entire cross section for the hollow part.
