A turntable is a musical instrument that converts sound signals into physical rotary motion. It is usually powered by a power supply or batteries. The instrument consists of a high-speed platter, a frame, a swing arm and a phono cartridge. The turntable is used to play music from vinyl records.
Operating principle of the turntable
The turntable works on the principle of electromagnetic induction. The platter is set in motion by a magnetic strip or series of magnets and windings. Then the platter generates a current in the platter, which is read by the phono cartridge. This cartridge consists of a crystal and a double magnet, which are powered by a power supply or a battery. Sound signals are sent to speakers or headphones.
