some experience with Ultra sound cleaner?
1 Attachment(s)

Im trying to make a small ultra sound cleaner using the piezo tweeters. I have experimented a little, with variable oscillator as a source, TDA2030 - 20W amplifier and 7 piezo tweeters connected in parallel. On some frequencies above 30KHz those tweeters achieved good results.
Now i would like to try to double the power and connect abt 20 piezo's to make the bigger sono-cleaner.
My question is, does anyone have tried this before and is it worth to use piezo's?
