The turntable cartridge is one of the key pieces of equipment that directly affects the sound of a vinyl record. Whether the magnet is vibrating and the coil is fixed, or the magnet is fixed and the coil is vibrating, it will cut the magnetic lines and generate current, and the size of this current is issued with the size of the music signal vibration. These currents will be converted into voltage form and input to the preamp, then through a RAA equalization line reduction in the preamp, continue to enter the signal amplification most, and finally from the speaker to send out music.
