Abstract
PURPOSE: To give the stiffness to the application direction of the stylus pressure and thus enhance the reproduction properties over the entire reproduction frequency band by attaching the leaf spring in parallel to the rubber damper of the cartridge.
CONSTITUTION: Hole 9a at the basement of leaf spring 9 made of bronze is fitted between magnet 3 and damper 4 made of the isobutylene-isoprene rubber, and the cross-section of the hole fractures the J-shape. Projection 9b is formed at the tip of spring 9 to touch the wall of the holder provided at the opposite side to the tip direction of stylus 1. At the low frequency, the stylus tip's mechanical impedance is comparatively high due to the stiffness of the leaf spring. However, the mechanical impedance is lowered down via damper 4 at the high frequency. Thus the ample margin can be secured to the stylus pressure, and furthermore the reproduction properties can be enhanced over the entire reproduction frequency band.
