Äänilevysoitin

An äänilevysoitin, commonly known as a record player or turntable, is an electro-mechanical device used to reproduce sound from a vinyl record. It consists of a rotating platter onto which a vinyl record is placed. A tonearm, equipped with a stylus (needle), tracks the grooves on the record's surface. As the platter rotates, the stylus vibrates, converting the physical undulations of the groove into an electrical signal. This signal is then amplified and sent to loudspeakers, producing audible sound.

The äänilevysoitin typically includes a motor to drive the platter at a consistent speed, usually 33 1/3 or 45 revolutions per minute (RPM). The tonearm's design and the stylus material are crucial for accurate sound reproduction and minimizing wear on both the record and the stylus. Early äänilevysoittimet were purely mechanical, but modern versions are almost entirely electronic. The device is a core component of a hi-fi audio system, allowing users to enjoy music stored on analog vinyl records. Despite the rise of digital audio formats, the äänilevysoitin has experienced a resurgence in popularity among audiophiles and music enthusiasts.
