40-70khz motor driven speaker project

Hey forum,

I’m looking to design a speaker specifically for sound healing frequencies.

Since the audio will not be heard, the volume won’t need to change, the only thing that needs to change is the frequency.

With the same excursion the driver could be driven by an electric motor that varies only in speed.

I’m looking for a designer to design this in CAD, I understand that this would require specialised knowledge and isn’t something normal. I will compensate you well if you have the skill set to do this!

If anyone knows any companies I should reach out to, knows any people that build drivers or have any ideas for the project please let me know!

Peace, love and light
Jeremy
