Abstract: The music box can play beautiful music mainly because of the movement. The traditional handmade music box uses a clockwork movement. After winding up, it will automatically play a fixed track. With the technology With the development of music, two types of hand-cranked movements and electronic movements that can compose music by oneself have also been invented, but clockwork movements are still relatively common. There are many types of clockwork music box movements, mainly due to the difference in the number of notes, including 8 tones, 18 tones, 30 tones, 55 tones, 72 tones, etc. The more the number of tones, the more complex the movement structure will be, and the more complex the movement will be. The music is also richer. Let’s take a look at the movement of the music box. 1. In addition to the clockwork movement, what other movements does the music box have?

The movement of the music box is the core device for playing music. Generally speaking, there are the following two types:

1. Mechanical Movement

Mechanical movement is divided into two types: wind-up movement and hand-crank movement. The wind-up movement has a fixed track. After twisting the wind and loosening it, the music box will automatically play. The hand-crank movement can compose the music by oneself or fix the repertoire. If the music is composed by oneself, the hand-crank movement needs to have the ability to identify the hole position of the staff on the paper tape.

2. Electronic movement

The electronic movement is the product of music box technology in the electronic era. It uses electricity as energy and drives the movement to produce sound.

2. There are several kinds of clockwork music box movements

A clockwork music box is a common music box. It uses a clockwork to provide power for the music box to play music. Its core component is the sound barrel. The movement consists of , soundboard, gears, spring, damping and other components. It is a row of steel bars on the movement that look like piano keys.
