Most people don’t ever want to wear braces, a retainer, or basically put anything in their mouth unless it’s a delicious snow cone. I, however, might make an exception for the Play-a-Grill, a mouth-mounted MP3 player that bounces sound waves inside of your head.

Aisen Chacin, a Design and Technology student from the Parsons The New School for Design, created her musical mouth piece using a molding of her own upper jaw and wax models of her teeth. The rest of the device is made up of hacked parts from an MP3 player, a tongue-controlled interface, and a small vibration motor.

Instead of using conventional speakers, the device plays music by vibrating in your mouth. These musical vibrations pass from the concave shape of the palate to your jaw and resonate through your skull to your eardrums.

If the particular song you're listening to is loud enough, others nearby can actually hear the music coming from your mouth. You also don’t have to worry about getting a blaring dubstep headache, either, because these vibrations can only be heard and not felt.

It’s definitely an interesting device especially if you’re someone who is still sporting a metallic grill or a teenager who wants a fancier retainer.
