摘要:
In a pickup cartridge of moving-coil type, the components of movement of a cantilever in the vertical and horizontal directions are individually detected to produce two kinds of electromotive forces respectively proportional to the velocity of the detected vertical and horizontal components of movement. The sum and difference signals of the two kinds of electromotive forces are separately obtained for stereophonic reproduction of signals recorded on a recorded disk. The vibration system is given different vibration characteristics for vertical movements thereof than those for horizontal movements thereof, without sacrificing electrical output characteristics such as channel separation characteristic and low frequency response characteristic. First and second coils are arranged so that the axis of the first coil is parallel to the record disk and the axis of the second coil is perpendicular to the record disk.
