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

Question

Greetings AllI would like to vary an ultrasonic mist maker like this one 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 ableto 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.tia sal2

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 dowith the ultrasound?                      Mike

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.-- Regards, Joerg"gmail" domain blocked because of excessive spam.Use another domain or send PM.

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.-- Regards, Joerg"gmail" domain blocked because of excessive spam.Use another domain or send PM.
