This is a make-up of the assignment on actuators.
Since I was interested in Cymatics phenomena, I chose an appropriate actuator which could be used to generate vibrations that result in said patterns appearing. That device is the “3B Scientific U56001 Vibration Generator” with a frequency capability response of 0-20khz, a robust resolution considering the general capability of the human ear to recognize frequencies between ~20hz to 18,000hz [although there are considerable variations in this range]
Here is the product manual: http://www.a3bs.com/product-manual/U56001_EN.pdf
The device is lightweight at 1.4kg, impedance is rated @ 8 ohms. If that sounds a lot like a speaker, it is because it is basically a speaker, housed inside of a metal assembly and attached to a rod which oscillates based upon the frequencies inputted. The device, unfortunately, does not generate the actual input frequencies itself, for that you need a wave function driver or similar input [a software solution could probably be implemented].
A chaldni plate can be used in conjunction with sand/salt/particulate for observance of visual cymatic patterns, which I have documented here before. One can also attach several accessories to this 3B U56001, including a resonance wire, rubber band, spring, etc. for the study of wave phenomena… one particularly interesting real-world example of wave phenomena is the “Galluping Gertie” effect as exhibited here in the pre-Tacoma Narrows collapse and similarly, in a Russian bridge:
The mythbusters sort of tried to do this on a small scale: https://www.youtube.com/watch?v=7xODgR2FEKo
Resonance breaks wine glass at around 550hz.

thanks Peter, I had never seen the MythBusters ep, but I have seen that vocal coach on youtube shattering many, many glasses without amplification! Just shows you the power of vibration. Tesla also did work on this, I believe his “Death Ray Gun” and/or “Earthquake Machine” was based upon this principle, match the resonant frequency of something and interesting things happen!

I want to try this at home, but I don’t want the neighbors calling the cops. I’ll bring the wine and wine glasses next time… LoL
This is very interesting, its amazing how sound is able to cause this.
