Question on how to energize a air transducer

Ed2024
Ed2024 over 1 year ago

Looking at energizing 72 200KHz Air Transducers for a science experiment. Only need to send a signal not trying to receive it back also wondering if you can piggy back a second signal on the 200KHz air transducer.  Need a generator that will work for the transducers to work.

  What are the power requirements for the 200KHz air transducer. Your help would be appreciated, Ed

    I am confident that you will not be ignored if you can demonstrate anti-gravity. I am equally confident that you will not do so. Levitation using acoustics has been demonstrated but is no more anti…

    I can't tell from here, but that screw looks wrong - should be Pozidrive. Will never work with that one.

    It isn't clear what all of your constraints are or what your complete objectives are so it is tough to provide ideal advice. 200KHz piezo transducers can be driven by any microcontroller connected to a power transistor. This also allows the 200KHz signal to be modulated with on-off-keying. If all 72 are driven with the same signal, it is much simpler than if you need to modulate each one differently.
