Piezoelectric Speaker Kit - PZ-SPK
The piezofilm speaker kit is both educational and fun. The piezoelectric
material is a thin flexible plastic sheet with metalized surfaces. When
voltage is applied the piezofilm changes size. The kit incorporates
a LM386 integrated circuit that amplifies an electrical sudio signal
from an IPOD or similar device, and outputs the amplified signal to
the piezoelectric film which generates audible sound.
