PURPOSE:To obtain the audio vibration plate easy for the manufacture and improving the audio various characteristics remakably, by forming the construction that the internal part has a number of small air chambers with the material mixing graphite powder and resin. CONSTITUTION:The material mixing graphite powder and polyvinyl chloride as the core 1 is manufactured with injection or compression. After molding the core 1 in honey-comb, it is heated under oxidation atmosphere for preparatory baking. After that, it is heated under non-oxidation atmosphere and carbonized. Further, as the skin 2, graphite powder and resin are mixed and pressed into flat plate as the same as the core 1. Thus, at the surface of the core 1 thus manufactured, the skin 2 is bonded with the adhesives and assembled to form the honey-comb audio vibrating plate. |
