Abstract:
A moving-magnet type pickup cartridge is disclosed, which includes a cantilever, a stylus chip attached to a front end part in a longitudinal direction of the cantilever, a damper disposed at a base end part in the longitudinal direction of the cantilever and configured to support the cantilever in a swingable manner, a magnet disposed in the longitudinal direction of the cantilever and immediately above the stylus chip at the front end part of the cantilever, and configured to vibrate with vibration of the stylus chip, and a yoke formed in a U-shape, having generating coils being wound thereon, and having magnetic poles at both leg parts thereof being disposed to face the magnet. With this configuration, there is provided a moving-magnet type pickup cartridge enables not only to ensure a large output signal but also to obtain a faithfully reproduced sound with little distortion.
