Abstract

PURPOSE:To shorten the length of the cantilever itself and then to enhance the reproducing frequency characteristics at the high-frequency band, by putting the effective magnetic space close to the stylus tip and then providing the magnet oscillator within the magnetic space so as to secure the angular motion to the magnet oscillator. CONSTITUTION:Square attachment window 44 through which projection 43 provided on the back of replaceable stylus 21 pierces through is attached to cartridge main body 23, and magnetic space 42 is formed with yokes 39A, 39B, 40A and 40B of the power generation system 24 protruded over window 44. Then the hole part through which those yokes mentioned above pierce is formed so that it may enclose vibration system 22 provided at stylus 21. And the ample distance is secured between main body 23 and record surface 45 when the distance is shortened between surface 45 and vibration fulcrum 46 of system 22. Thus substantial space 42 is put close to the stylus tip 25, and magnet oscillator 27 is provided within space 42 so as to secure the angular motion. As a result, the length of cantilever 26 itself is shortened, thus enhancing the frequency characteristics at the high-frequency band.
