![]() ![]() These variations in the magnetic field generate a small voltage in the coils, which corresponds to the movement of the magnet (thanks to Lenz's Law). This signal is then passed through a phono preamp (for RIAA equalization) before reaching the amp/speakers, which convert the electrical signal into sound. As the magnet vibrates, its magnetic field varies. Vibrations from the stylus tip travel along the cantilever to the magnet. The rubber suspension allows the cantilever to pivot so that the stylus can accurately track the grooves. The cantilever is a rigid tube with a stylus mounted on one end and a magnet on the other. As the stylus traces the movements of the grooves, it vibrates the cantilever. The diamond stylus tip is the only part of the cartridge that makes direct contact with the record. ![]()
