Music Box
★Exhibit Content: Photoelectric signal control, generation and patterns of music ★Interaction: Electromechanical interaction ★Operation: 1) View the graphic panels to learn related knowledge; 2) Slide the note blocks and fix them, turn the drum, when the small stick plucks the hammer, it drives the hammer to strike the reed above, causing the reed to vibrate and produce sound. ★Exhibit Description: The exhibit mainly consists of a crank, manual music drum, sound-producing device, transmission mechanism, note bars, etc. Turning the crank drives the music drum of the note bars to rotate at a constant speed. When the note bars pass the sound bars of the sound board, they pluck the reeds, causing the reeds to vibrate at a set frequency and produce sound. ★Scientific Principle: The principle of a music box is that power drives a music drum with small protrusions on its surface to rotate at a constant speed. When the protrusions pass the sound bars of the sound board, they pluck the reeds (first slowly lifting them, then suddenly releasing) causing the reeds to vibrate at a set frequency and produce a set sound. The sound board part of a music box is made by cutting thin strips of equal length but varying thickness and width from a spring steel plate (thickness and width vary according to the set vibration frequency). A protrusion on the music drum is equivalent to a note in a musical score. A music drum has protrusions set in a regular pattern. As the drum rotates, the protrusions brush past the edge of the sound board. Due to the different protrusions, different sounds are produced. In addition, damping causes the drum to rotate at a constant speed. A typical ordinary movement completes one revolution in 8-17 seconds, which is enough to express the climax of a piece; of course, high-end music boxes usually cycle between 30 seconds and 8 minutes.
