Vinüüliplaadimängija

Vinüüliplaadimängija, commonly known as a turntable or record player, is an electro-mechanical device used to reproduce sound from vinyl records. It consists of a platter that rotates at a constant speed, typically 33 1⁄3 or 45 revolutions per minute (RPM), upon which a vinyl record is placed. A tonearm, equipped with a stylus or needle, is positioned over the spinning record. As the stylus tracks the grooves etched into the record's surface, it vibrates and translates these physical movements into electrical signals. These signals are then amplified and sent to loudspeakers, where they are converted back into audible sound.

The core components of a vinüüliplaadimängija include the motor, which drives the platter, the platter itself, the tonearm, and the cartridge containing the stylus. The cartridge, often a moving magnet or moving coil design, converts the stylus's vibrations into a low-level electrical signal. A phono preamplifier, either built into the turntable or a separate unit, is crucial for boosting this signal to a usable level and equalizing it to compensate for the RIAA equalization curve applied during record mastering.

Turntables vary widely in their design and price point, from basic, entry-level models to high-fidelity audiophile systems. Factors influencing sound quality include the precision of the motor and platter, the mass and design of the tonearm, the quality of the cartridge and stylus, and the overall construction and damping of the turntable's chassis, which helps to minimize unwanted vibrations. Despite the rise of digital audio formats, the vinüüliplaadimängija has experienced a resurgence in popularity among music enthusiasts who appreciate its unique sonic characteristics and tactile experience.
