Hi All,
I'm looking around at piezo transducers for a project I'm starting on and I thought I'd check here for a bit of advice before buying. I'm looking to build a keyboard that plays wine glasses. Basically the idea is oscillators into piezo units attached to wine glasses.
Many transducers I come across list their resonant frequency. I don't know how important a spec that is for my needs. What does this equate to in actual use? Something I need to concern myself with when running sine waves into them? Most of the resonant frequencies seem to lie above where I'll be using them at, between 2k and 5k, whereas I'm working with glasses who's fundamental is in the range of 300 to 1500hz.
Anyone know of a good type that's findable in the US that would work well for sticking to wine glasses?
