I found this piezo ultrasonic transducer in local store. I think this is the right one? What you think?

Also what kind of transformer is good to use, i mean 12 to 12 volts? Or 220 to 12?
Is it silly of me that the first thing I think of is a guitar pickup transducer.?
As far as transformer goes an "isolation" transformer would work best. Any AC transformer should also work well, Typically, a high impedance device like a piezoelectric buzzer should be connected to the higher voltage output of the transformer. This is because a high impedance device requires a higher voltage to drive it than a low impedance device.
Hi Joel,
I'd like to experiment with the Web App thas was on http://typeright.social/neurophone/. It said visit help for circuit diagram. Would you mind sharing the circuit diagram?
Thanks in advance!
