Abstract
PURPOSE: To secure the porper Young's modulus and the hardness for the ceramic material which is one of the elements for the vibration system of the record player as well as to prevent occurrence of the resonance by using the poly-crystal sintered material wich is composed mainly of the alumina with the specified Young's modulus.
CONSTITUTION: For the vibration system of the record player in which cartridge 1, head shell 2, tone arm 3, weight balancer 4 and others are integrated, the ceramics composed of the poly-crystal sintered material of the minute alumina crystal featuring the average grain size of under 10μm and with the Young's modulus between 1.4W2.8×106kg/cm2 is used to form head shell 1.
