Back in 2011, I designed and built an ultrasonic transducer+horn assembly and a power oscillator for driving it. My webpage on this proved to be reasonably popular, and I've had many inquiries about the horn design process. I thought it was about time to do a proper video that tries to cover all the common questions.
Links to video chapters:
00:00 Introduction & circuit
01:44 Bare transducer measurement
03:40 Effect of loading
04:31 Horn design & initial testing
09:57 Finished horn, different tipes, nodes & antinodes
19:16 Sinewave vs. squarewave excitation
22:41 Temperature effects
24:41 Conclusion
