The stylus mass and the groove compliance in phonograph reproduction give rise to a resonance at high frequency, which, even when compensated electrically, causes deleterious side effects. This resonance cannot be damped effectively by addition of series damping as it would produce excessive forces with high-velocity mid-frequency modulations. By subdividing the stylus-inductor structure into two parts connected by a semi-viscous coupler, a -dynamic damping- is obtained, which eliminates the resonance while at the same time diminishing the forces which the groove is called upon to furnish.
