Music box

A music box is a mechanical device that produces sound without electricity. Inside, a rotating cylinder or disc with tiny, engraved bumps or pins triggers a series of tuned metal prongs or teeth, causing them to vibrate and produce musical notes. A comb-like structure amplifies these vibrations, creating melody. Traditionally, music boxes are wound up with a key or handle, storing potential energy that drives the mechanism. They are cherished for their intricate craftsmanship and vintage charm, often used as decorative items or keepsakes, and can play a wide variety of melodies depending on their design.
