Abstract

PURPOSE:To reduce the weight of the vibration system as well as to increase the magnetic moment and the damping effect by loading the bar-type magnet and the conducting magnetic substance disk into the rear part of the cantilever and toward its axial core. CONSTITUTION:Bar-type magnet 3 featuring the magnetic poles across it is inserted and fixed to the inside of the rear end of cantilever 1 containing reproduction stylus 2 at the tip and in coincidence with the direction of the axial core. At the same time, disk plate 4 made of the conducting magnetic substance is fixed at the rear edge of lever 1 and then connected to magnet 3 magnetically. Wire 5 is fixed at the center part of plate 4 to stretch the plate and thus to support lever 1. In such constitution, the weight of the vibration can be decreased, at the same time obtaining a cantilever vibration system featuring the increased damping effect and the magnetic moment.
