sound wave vibration DemonstrationSound wave vibration Demonstration ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
In this study, mainly by the speaker, foam balls, MP3, cradle, power amplifier IC circuit, and the corresponding switch and volume potentiometers and other components (as shown above).
Sound waves emitted from the speaker directly driven plate, the foam plate vibrate pellets, which can prove that the vibration of the sound generated from the object, different vibration produces a different sound
The overall specifications of the device 350 mm * 260mm * 180mm; the base by use of PVC mold molding, the base specification: 350mm * 260mm * 70mm; four using special rubber pad 10mm high, to prevent vibration and sliding.
Power supply for 12VAC/DC2000mA.
The MP3 module is fixed on the base panel; IC power amplifier circuit is fixed in the base, a high-power horn hidden inside the base; the power switch and volume potentiometer mounted on the panel.
The panel fixed phi 200mmx100mm acrylic cylinder cylinder, cylinder placed uniform foam ball.
