For over a hundred years, listening to speeches, recorded music, lessons, and languages with the aid of a record player was common place. Through the years, the strategy has evolved, but the idea has experienced little change, and the important parts have not experienced any change.
The turntable is the round plate where the record is put on. A bar in the middle holds the record (with a hole in the middle) together. The metal turntable is coated with plastic or rubber, which prevents the record from being dented. The turntable revolves with the aid of either a direct drive system or a belt drive.
The needle or stylus is most likely the most significant part of the record player. It is crafted with a hard material or diamond, designed like a cone and held by an elastic strip of metal. The pointed end is the only part that comes in contact with the upper part of the record and it revolves around the spiraling hollows of the disk, receiving the vibrations which are in turn processed into sound.
The stylus is located at one end of the tone arm, which rests at the other end of the turntable and is opposite the record. With the stylus or needle located in the record’s furthest groove, the tone arm tails the hollow as it coils inward, moving across the record in a semicircle as the record revolves underneath it. Whilst this is happening, the vibrations move through an elastic metal strip and wires enclosed within the tone arm to the cartridge situated at the tone arm’s end. The cartridge picks up the vibrations, which are transformed to electric signals via a coil in the magnetic field. The electric signals move through wires to the speaker which amplifies the signal. Lastly, the signals are transformed to sounds that come out through amplifiers.
