Abstract

PURPOSE: To reduce greatly the noise contained in the reproduced signal, by increasing the antiresonance frequency higher than the audible frequency among the vibration transmitting properties of a tone arm.
CONSTITUTION: The tone arm resonance frequency (ωr) which controls the reproduction property of the tone arm is shown by the equation I, and the value by which the arm is made to follow the waves of the record is set to 10Hz or so. If the conditions can be satisfied to set the (ωr) at 10Hz or so, the inertia momemt J around the rotating shaft 8 of the arm 6, the full mass (m) of the arm 6, the distance Lc between the shaft 8 and the stylus 5 and the distance Lg between the shaft 8 and the center of gravity G of the arm can be altered freedly. In this connection, the antiresonance frequency (ωa) is set higher then the audible frequency. As a result, the noise in the reproduced signal can be eliminated substantially even though the shift base 9 may have an intermittent motion.
