Abstract

PURPOSE: To make it possible to damp high-frequency resonance effectively without detracting anything from the follow-up property in terms of intermediate and low frequency range by providing the 2nd damping material between a stylus and damping material and by setting its resonance frequency nearly equal to the high- frequency resonance frequency of a vibration system.
CONSTITUTION: The base end of cantilever 3 is pulled by wire 5 to press armature 6 against holder 7 with damping material 8 interposed. In the meddle of cantilever 3, the 2nd damping material consisting of ring-shaped mass body 10 and elastic body 11 is fitted. The resonance frequency determied by the mass of this mass body 10 and the stiffness of elastic body 11 is set nearly equal to the high frequency of the whole vibration system including cantilever 3. Consequently, as the vibration frequency approximates the high frequency range, elastic body 11 of mass body 10 resonates to apply damping in proportion to the displacement of the vibration system. Consequently, frequency response characteristics can be flattened without detracting anything from the follow-up property in terms of intermediate and low frequency range.
