Which physical object sends random vibrations?

No, not even close. Look into the chaos oscillator stuff and you'll see it's quite different. The waveform does have a specific frequency, but it contains a lot of harmonics which would not be present in a filtered signal. Also look at avalanche reverse-breakdown and the random ramp waveforms (very similar) generated that way.
The whistle mentioned in the linked article is going to exhibit a waveform similar to that due to pressure built up by turbulence being suddenly released.
Regardless, you're not going to find a reliable way to trigger this sort of motion and the thought you might is honestly ridiculous.
Instead, you can drive a motor or if you're really completely insane you can attempt to control the shape of the physical result using a servo. One servo you might be familiar with is also known as a "speaker".
You can purchase both of these for a few dollars and drive them with any signal you like.
For example if you need very high frequency low-distortion output you can build your own "candle tweeter", a plasma-arc transducer with its plasma generated reliably by a candle. Of course you have to avoid blowing out the candle and use of paper or other flammable cones is not recommended
If you want bandpass filtered noise get an air pump and a flue pipe.

How about using resonant bandpass filtered white noise?

What you seem to describe does not exist. Any physical object will have one or more resonant peaks. These are a function of its dimensions and material properties. You cannot beat physics.

You mean when the harmonics have frequencies too close to each other. it starts to sound like all resonances has their own volume LFO.HTBoogie wrote:Any physical object will have one or more resonant peaks. These are a function of its dimensions and material properties. You cannot beat physics.

I believe you're describing a tuning fork....

keep hitting it forever then

Why edit my post to say "flute" when I clearly said "flue" ? They are not the same thing!Jedinhopy wrote:I meant it should sound like bowed string and not blown pipe.aciddose wrote:If you want bandpass filtered noise get an air pump and a flute pipe.
