Abstract

PURPOSE: To decrease the sensibility to vibrations and at the same time secure the sudden attenuation for the vibration by constituting the tone arm for record player with the ceramic sintered substance featuring the specific porocity and stomatal diameter.
CONSTITUTION: The tone arm is constituted with impregnation of the elastic material such as the rubber, the plasticized resin or the like into the ceramic sintered substance featuring the porocity of 20% or more and the stomatal diameter of average 300μ or less or into at least part of the pore of the ceramic sintered substance, along with the ceramic molded substance formed through combination of ceramic particles and the resin or the like or with impregnation of the elastic material such as the rubber, the plastic resin or the like into at least part of the pore of the molded substance. Thus the sensibility to vibrations can be decreased owing to the high rigidity and large mass of the ceramics, and the vibration is suddenly attenuated by the pore contained in the ceramics. As a result, the good sound effect can be obtained with the high performance.
