Turn anything into a speaker.

Slap on the Rock-It 3.0 Vibration Speaker's sticky connector into anything and it will use that object's mass to amplify your music. One thing to remember is the more hollow it is the better sound quality it produces. If the music isn't loud enough you can combine multiple Rock-it 3.0s to produce a more powerful sound. This gadget can crank up 10 hours of playtime from a single charge and can be connected to any device that has a 3.5mm headphone jack connector. Amaze everyone when you play your jam using this new revolutionary speaker.
