Piezoelectric Microphone. By : Keundra Waller and Chris Burke : ). When the microphone was invented and who invented it ???. In 1877, Emile Berliner invented the first microphone . Where and how the microphone is used ???.
Piezoelectric Crystals. MEEN 3344 By: Matthew Kelso. Piezoelectric Crystals. Crystals that generate a voltage when a stress is applied to them. The inverse effect is also true: a voltage causes deformation. This is due to complicated crystal structure that is unsymmetrical about the center.
