Abstract

PURPOSE: To obtain the high performance canti-lever light in weight and high in the rigidity, by kneading the resin and graphite powder in mixture and orientating the graphite powder with rolling flat plate into molding, and carbonizing or graphiting the molded body.
CONSTITUTION: After heating and kneading in mixture for 30% of polyvinylchloride and 70% of graphite powder 20μ or less in the average particle diameter, for example, the mixture is rolled and the flat plate 3 in which the graphite powder 2 is oriented in the plate 3 in the resin 1 is made. The plate thickness of the flat plate 3 is determined in matching with the thickness of the canti-lever 3. The plate 3 is made in matching with the diameter of the canti-lever 5 and the joint 4 is pressed or bonded with adhesives. After preparatory sintering of the canti- lever 5 molded under oxidized atmosphere to 250°C gradually, the molded body is carbonized at 1200°C under non-oxidized atmosphere or vacuum to increase the rigidity at about 4 times that before carbonization. Further, about 1.5 times rigidity can be obtained with graphiting at 2500°C or more. Thus, the reproduction excellent in the audio quality can be obtained.
