stereo turntable MAGNETIC CARTRIDGE. MOBILE MAGNET SYSTEM ~ CLASSIC HI-FI EQUIPMENT

2017-06-10





In this type of design, a small magnet, as powerful as possible, is associated with the needle-holder lever and when moving into motion, it modifies the magnetic flux that crosses fixed coils where a current is generated. The technical problem to overcome in this type of system is the weight of the magnet that is associated with the lever, because, one of the basic parameters to obtain good results is a very low mobile mass or effective.

Reducing the weight of the magnets reduces their efficiency and therefore the output voltage. However, it is a system that provides sufficient good results for the technological development achieved in the manufacture of magnets. Among the manufacturers using this system are Shure, Audiotecnica and AKG.
