Funny thing is that I'm currently drinking cold brew that I prepared on my acoustic cavitation brewer.
It's called Osma Pro. The company that made it sadly did not survive, and they took a lot of heat (no pun initially intended) for the price point and various complaints about how it worked.

Luckily, mine works great and I like it a lot. I use it every morning.
Takeaway point: maybe Google your idea to see if other people have also had it before describing it as new.
