Abstract
PURPOSE: To reduce the movement of the centroid position of a counter weight and eliminate the restrictions of player case by forming the moving mechanism of counter weight and the adjusting mechanism of resonance frequency of a dynamic absorber in a telescopic structure.
CONSTITUTION: The counter weight consisting of a housing 14, adjusting screw 15, adjusting guide pin 16, chuck 10, spring 11, weight 12, viscous material 13 moves in its axial direction as a moving screw 6 is turned. Turning of the adjusting screw 15 causes the chuck 10 to be moved in the axial direction by way of the adjusting guide pin 16, by which the free length of the spring between the chuck 10 and weight 12 is changed and the resonance frequency (f) of a dynamic absorber is changed by the formula 1. In this case, the distance between a bearing 2 and the rear end of the counter weight does not change at all and the movement of the centroid position of the counter weight is small. Hence, the restrictions of the player case mounting the tone arm may be eliminated.
