How can I vary an Ultrasonic Mist Maker vibration using a soundcard tia sal2

[sal2]

Greetings All

I would like to vary an ultrasonic mist maker like this one
http://www.physlink.com//estore/cart/UltrasonicMistMaker.cfm
using my audio sound card.

Example:
I want to produce complex waves using my sound card 4000Hz square wave
combined with some 1000 hz sine waves etc.. I would like to be able
to vibrate the ultrasonic mist maker transducer at this rate. Is this
possible?

I can create the audio waves easily but I'm not sure how to drive/control
the vibration of the ultrasonic mist maker using the signal coming from
my sound card. Does anyone have any recommendations? I'm trying to keep
this as cheap as possible and use a ultrasonic transducer off the shelf.

these devices are design with optimun efficiency as bought changing freqency will change the efficiency . besides what do you expect to achive better results?

Most of the mist makers I'm familiar with run at 1 to 2 Megahertz.
Your sound card frequency is way to low. What are you trying to do
with the ultrasound?

Usually you can only modulate it. So he'd have to build a modulator that
gets added on to the generator in the box and then feed that from the
sound card.

again your idea is lame this is a vibrator design with mechanical dumping as with a spring it will oscillate mybe as some hamonics. it has nothing to do with frequency as in electronics but it has everything to do with the mechanics of the thing.

Try putting the fog generator between two speakers or one speaker and a
wall. Might be interesting to see if you can see visible standing waves
somehow.

Or light up a nice big stogie. Might be frowned upon in some places though.
