Purpose & Scientific Principle
The exhibition item mainly consists of a concave sound concentrator, a triangular groove filled with steel nails, and steel balls.
How to Operate
Slowly rotate the triangular groove, and the small balls continue to fall in the triangular frame. These small balls collide with many nails during the falling process. During each collision, they will hit the steel needles and make a sound that is amplified by the concave sound concentrator. Because the lengths of the steel needles are different, the sounds produced by the small balls hitting each steel needle are also different, like a "Gaussian melody". 1.
