Sound energy experimental apparatus ,This is our new creative series which used for junior middle school Innovation experimental ! new beautiful design and very eash to be used.
The device contains IC circuit, speaker, microphone, acrylic voice resonant cavity, power switch, power indicator and the base (as shown above).
the sound input through the microphone, amplified by the IC circuit and output by the speaker; sound resonance in the resonant cavity, air in the cavity resonance come out through the small vents and blow out the candles light or blown away feathers.
Sound generated by vibration of the object, spread in the air in the form of sound waves and will cause the air vibrate.
All the waves has energy, this experiment can prove that sound wave spreading in the air also has energy
Overall product specification: 350mm × 260mm × 300mm.
Using a common base of PVC molding, base size: 350mm × 260mm × 70mm; 10mm high legs using special rubber pads to prevent vibration and slipping.
Power input: 12VAC/DC1000mA (universal adapter); condenser microphones; standard 2.5mm speaker input interface; push-button power switch with red LED power indicator; loudspeakers fixed on acrylic resonant cavity, and use nylon molding universal bracket on the base.
