Music Box - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:

The exhibition items mainly consist of a handle, manual sound tube, electric sound tube, pronunciation device, transmission mechanism, note stick, and other parts. The rotating handle drives the cylinder with a note stick inserted on its surface to rotate at a constant speed. When the note stick passes through the soundboard and the sound bar, it will move the reed to vibrate at the set frequency and produce sound. Set up two rotary drums, one manual rotary drum, controlled by a crank to rotate; The other one is an electric drum, which can be started by a button. Install a note stick on the outside of the sound tube, and press the note stick to control its protrusion or retraction.
