We need to force into oscillation a small card (50 gr) hanging from a wire.

After evaluating all acceptable means (for us) we found that blowing a tiny jet of air from time to time will do.

Without resorting to microblowers, we DO know they exist, (expensive and hard to get locallly), would you suggest something else to obtain a gentle air blow lasting for less than one second every time is needed?

Please note we are not looking for other solutions; just to generate a gentle, very quiet, air blow.

Mechanical noise is a no no and air volume required is definitely SMALL.

I may have the wrong idea here but would a sealed speaker or piezo disk, attached to a fine nozzle, have the desired effect when pulsed?
 
Hi Agustín.
Use Nitinol - the muscle wire to move in a fanning way forth and back (abanico), or if you prefer, to push/pull the hanger string. No sound at all, and as much action as needed.
 
Another idea would be a small fan, running at very reduced voltage...both quiet and gentle.
 
Trying that right now

So many ideas...

Yours seems feasible provided we get a small fan, not necessarily a ublower.

Instead of changing voltage... PWM might be.
