トーンアームの屈曲振動

概要

The bending vibration of a tone arm, mostly used in usual disk record players and named 'swing type' is studied. The bending vibration is calculated by the method of transfer matrix and observed experimentally. The frequency response and modes of vibration are numerically calculated. The results obtained are as follows:(1)The first resonant frequency is at about 100 Herz and dominated by length of the pipe and weight of the head mass. (2)Because of the not enough stiffness of the headshell-pipe connector, the second resonant frequency appears. (3)The third resonant frequency is located at nearly 1000Herz. Then, the influence of these bending resonances on the disk record reproduction system and some methods of avoiding the influences are discussed.
