I have several dumb questions regarding piezo-electric transducers. I am considering using one in place of a loudspeaker in a future design. What drive characteristics do they typically have? voltage? current? impedance? Do they need to be driven a their resonant frequency? Are they good only for buzzers, or can they also handle voice? I am attracted by their size and price, but don't know too much else about them. Thanks for any info. -- Joe Hingston "A screaming comes across the sky" Apple Computer, Inc.
