OEM OrigAudio Universal Portable Rock-It 2 Vibration Speaker 3.5mm - Black
I had first seen a vibration speaker system that another family member had. When I researched it, I found the Rock-It product, and it was considered an OEM. It's one of the items that maybe was more improved on with other companies starting to get in on the idea. It's an okay sound on what seemed to be a more limited number of surfaces than what my other relative had. Volume is a little sketchy and sound jack connecter wire seemed a little short. Still discovering different sound qualities with it though.
