Can anyone recommend a commercial supplier, and application data, for
broadband piezo transducers?

IOW those operable in non-resonant mode to emit a wide range of
frequencies. I am particularly interested in the audio range upward to
several tens of KHz.

Best regards,

Brüel & Kjaer should have what you need.

Hello Dorris,

frequencies. I am particularly interested in the audio range upward to
several tens of KHz.

I don't know much about the kHz range since I usually design in the MHz
range. I had excellent experience with this company:

There are many others. Google for PZT or PZT-5H suppliers and then ask
them for low frequency materials. Also, check the very large ceramic
parts manufacturers such as Murata. I don't know if they supply wideband
stuff though.

Just a word about PZT and other ceramics: All transducers have a
resonant frequency and that is (usually) determined by their thickness.
How broad the usable band is depends on many factors, one being your
circuitry. IOW you or an engineer in your company needs to really
understand this stuff. Or hire someone who does ;-)

Regards, Joerg
