Adding Sound Generation

[Alarm Siren]

That's an interesting concept. I came across something similar when I worked at an electronics retailer, LG televisions which used the screen itself as a diaphragm. Got round the whole problem with modern, improbably thin televisions having rubbish sound because the speakers are tiny, and I have to say it worked very well. I'll order a couple of them and do some experimentation....

BTW, "piezo" is frequently mispronounced. It comes from the Greek work meaning "to bend," and with the Greek vowels, says "pee-eh-zo", not "pie-" (as in "apple pie"). Classical Greek had the "d" sound in front of the "z" sound, so "pee-Ed-zo" would be correct too. (Take if from our son whose undergraduate degree was in Greek and Hebrew, and got further education in it in his two masters' degrees.)

I've always butchered it as "pee-zo". Just plain easy to say, and I've never heard anyone pronounce it.

I've always said Pee-Zee-Oh, and the very few people who have said the word to me have said it the same.
