Abstract
PURPOSE:To make easy the manufacture of horn and to uniform the quality of products, by giving the characteristics of rigidity and high loss required for the speaker horn through the use of foamed plastic material adding balloon. CONSTITUTION:The separation type foaming agent is added in a suitable amount to the powder of pellet of the thermoplastic forming material such as polyvinylchloride or thermo-setting forming material such as phenolpolyester. Further, as the reinforce material, glass, ''sirasu'' balloon, or glass fiber is added in a suitable amount to obtain the specified rigidity and high loss performance, sufficient mixing is made to avoid unmixing speaker horn. Further, this raw material is injected to the molding with the injection machine of the in-line screw type to mold the speaker horn 1 having required rigidity and ligh loss performance having the balloon 7, glass fiber 8 and hole 9 in the resin frame 10, allowing to uniform the quality of the horn 1 in mass-production.
