The history of mechanical music is rooted in England, where bell towers rang out melodies to mark the hour. Swiss crafts men miniaturized this concept and created the first music boxes, which at the time were solely for aristocrats and the royalty of Europe, Asia and the Middle East. A half century ago, inexpensive Japanese brands made mass-produced music boxes for the first time.

In 1992, it is the Yunsheng that made the first music box with independent property rights in China. Yunsheng musical movements combine the art of music with the science of precision machinery to produce wonderful musical pieces that can be enjoyed in a wide range of musical products. After several generations of Yunsheng people’s unremitting efforts, Yunsheng has gotten a series of noticeable achievements.
