  • Great demonstration! So we would call this "to drive it with a parametric oscillation", not just a direct connection right?

    Also, in a guitar or almost any other string instrument, the relationship is reversed right? Instead it is the string which is parametrically driving the wood on the top case, creating a powerful sound amplification.

    Btw you should do more videos with that equipment, there's much for us viewers to learn :D
