Industrial piezoceramic for sound production?

Question

Can you please share some information about this.

I already understand that piezo or piezoceramic is voltage driven, meaning it requires a higher voltage and lower current. It can be made to cover a wide range of frequencies.

I also understand that the discs commonly used for sound production, can be made in a wide variety of power levels, and can even be custom made.

I also understand, that the disc is often placed in some type of housing, commonly to form a beam. This housing, whether for acoustic, or industrial use, is precisely constructed to reduce noise and distortion, which are detrimental to most applications. I understand that this process can often follow very detailed specifications and can be very expensive.

Thanks Steve,
As far as I know, you still need "some type" of housing to form a concentrated beam. Although, maybe the sound from the face of the disc is more powerful.

I wonder if it is possible to get samples of these discs in a variety of frequencies, voltages and power levels? Also, i wonder if i could pay a little more to have the electrodes already attached.

Also, i wonder how i can select a disc with the highest sound pressure or spl?

Also, i wonder how robust these discs are? If i was to put too much voltage through the disc i wonder what happens?

Answer 1

Piezo electric transducers also work in the same way for ultrasonic tanks and give a fairly concentrated beam. Not sure qiute what info you need.
