Abstract

PURPOSE:To reduce the total mass of a pickup cartridge while raising an output voltage by simplifying a magnetic circuit and by using small sized magnets. CONSTITUTION:A coil body 5 is so constituted that left and right signal detecting coils 3 and 4 are sound around a bobbin 17 at 90 deg. to each other and at 45 deg. to a horizontal surface. Two of magnets 10-13 are arrayed for one channel in nearly the same direction with the lengthwise center axis X-X' of a cantilever 2. The magnets when viewed from the front is bent at a 90 deg. internal angle and at 45 deg. to a horizontal surface. Since adjacent poles of the magnets are different, electromotive forces generated at the coil are added together to eliminate leaking magnetic flux, increasing the density of magnetic flux.
