Music Box/Music Piano/Sound of Music - Science Museum Exhibits Plan
What It Shows
A cylinder is made with several regular protrusions, each column of protrusions having corresponding metal pieces. When the circular axis starts to rotate in a regular manner, the protrusions drive the metal paddles to bounce and fall. With the driving of different protrusions, different sounds are produced. In addition, when it rotates, a fixed song will be produced after one round. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Remind everyone to insert some small wooden sticks themselves and create a music.
Science Behind It
The principle of a music box is to uniformly rotate the sound tube with small bumps on the surface driven by electricity. When it grows up, the article points out that the soundboard switches the reed (slowly lifting first, then suddenly lowering) according to the vibration frequency and set of the reed's vibration sound. source factory of science museum exhibits - Shanghai Inertia Automation Co., Ltd. Please note that a portion of the music box on the soundboard has the same cutting length on a metal plate, but the thickness of the thin strip varies depending on the vibration frequency range (thickness).
Exhibition items description
This exhibition items feature multiple cylinders with rows of circular holes corresponding to the number of spring plates. Viewers can freely choose different positions and quantities of circular holes, insert small sticks into holes of different rows and orders, and rotate the rollers to compose different music.

How to Operate
1. Watch the graphic board and learn related knowledge;
2. Insert the stick into the circular hole and rotate the drum. When the stick moves the hammer, it can drive the hammer to strike the spring on top, causing the spring to vibrate and make a sound.
