Early digital music players were cone-shaped, allowing the tiny squeaks of MP3s to be amplified to a listenable level without having to rent a cave. Pursue sonic superiority with today’s Groupon: for $20, you get one Rock-It portable vibration speaker system (a $49.99 value). The Rock-It turns common household objects into a speaker by converting music from your device into vibration sequences. Stick the Rock-It to any surface—such as a cereal box, picture frame, plastic cup, or sketchbook of Terminator prototypes—and let your favorite songs resonate through the ready-made framework. The speaker’s panel can be cleaned with water when it gets dirty, enabling repeated stickiness, unlike a Spider-Man costume. Either USB power or batteries can keep the Rock-It charged, enabling continued rocking long after lightning storms subside.

- Rock-It is the first ever portable vibration speaker that will turn anything into a speaker. It turns music into vibration sequences and sends them through the Rock-It pod, which you can stick to any object and turn it instantly into a speaker. – National Geographic
