Vibration of Sound
★Exhibit Content: Popular science on the principles of sound vibration and propagation ★Interaction: Electromechanical interaction ★Operation: 1. Face the horn and blow forcefully; 2. Observe the jumping trajectory of the laser spot on the opposite screen/wall as it changes with the pitch and intensity of the sound; 3. Change the blowing force and frequency to compare the differences in the spot patterns. ★Exhibit Overview: The exhibit consists of a horn model, amplifier, laser emitter, etc. A mirror and laser emitter are installed at the sound outlet of the horn model. During interaction, the visitor blows the horn on the table, and the vibration of the sound waves inside the horn causes the mirror to vibrate. At this time, the visitor can observe the movement trajectory of the laser spot. ★Scientific Principle: Sound is a mechanical wave generated by object vibration. Sound waves with frequencies between 20Hz and 20kHz can be recognized by the human ear. Sound waves propagate through the air and act on the mirror at the horn mouth, causing tiny displacements; the laser irradiates the vibrating mirror, and the reflection angle changes with the mirror's vibration, amplifying the tiny displacement into a large spot trajectory, thereby achieving the effect of "seeing" vibration. Changing the force and frequency of blowing will cause the jumping amplitude and trajectory of the spot to change accordingly, intuitively reflecting the relationship between sound intensity, frequency, and vibration.
