What does a piezo emitter feel like?

For one project, there is an idea to use piezo emitters similar to those in the picture, the essence of the "device" is that if it is touched, it would be possible to determine "tactilely" whether it sounds or not, and if it does, how strong it sounds. Because there is no such thing at hand and it is not foreseen until the weekend, maybe someone knows how much it can "fluctuate" when sounding, is it really possible to feel whether it sounds without straining or not?

Quite realistic, especially if you take a smaller frequency.

If the sound frequency - yes. If ultrasonic - no.

It became interesting, I rummaged through all my old trash in search of a Montana watch, but the watch went somewhere :(

When applying to the piezo emitter of its resonant frequency (usually 4 kHz.), It sounds distinctly, without hearing strain. If you use the same piezo emitter, but in a case, for example like this , then the volume will be decent. You can connect directly to any Arduino output (except A6 and A7), the second output to the "+" or "-" power supply.
You can check the performance with a sketch from the Arduino IDE examples => 02.Digital => toneMelody on pin 8.
