Hi guys not a very technical question but my lecturer was raving about how cool the airharp project was, in particular how realistic the sensation was of moving strings in the box when the internal speaker provided sound and vibration that can be felt through the surface of the box.
I was just wondering what speaker was used and where I might get something similar for my Hang Drum project, as I would also like it to have an internal speaker, ideally one that doesn't need to be switched on from the outside (passive?)
Thanks for all your help so far!
