Technology / Home Audio / Piezo (Tweeter): A tweeter whose motor is simply a crystal of Piezo material through which the signal current flows. The crystal lattice responds to this by bending in proportion to the Amplitude and frequency of the incoming signal. Because it is a high impedance device, it does not need a Crossover in line with the source. Piezo tweeters are very efficient Drivers and are relatively inexpensive. They come in a large variety of designs and radiators.
Technology / Home Audio / Piezoelectric Driver: This is among the most robust and least expensive alternative drivers for the high frequency reproduction. The material used in the Piezoelectric Driver is a piezoelectric polymer first developed in t MORE
Entertainment / Photography / Piezo-Electric Flash: Tiny flash bulbs (normally housed in flash cubes) which can be fired by a very low current produced by striking a piezo-electric crystal. Such bulbs can therefore be used without a battery. MORE
