Abstract

PURPOSE:To achieve the improvement in output characteristics by making the magnetic field of the regions bisected at the center of a pickup coil to opposite polarities. CONSTITUTION:Magnet pieces 12, 13 of mutually different combinations are provided in the upper and lower two regions symmetrical to the center of the spiral form coil 14 of a coil plate 15 vibrating together with the stylus 3 of a pickup. Then, magnetic fields of mutually different polarities of the upper and lower two regions bounded by the center are applied to the coil 14 and the current free from any adverse influence such as counter electromotive force, leakage flux, etc. is flowed in the coil 14 wherein the spiral directions are opposite with the upper and lower of the center, in correspondence to the vibrations of the stylus 3, whereby the output characteristics of the pickup cartridge are improved.
