Speaker helps deaf to 'feel' music

Deaf people rejoice! If you love music there is a device that allows deaf people to "feel" music with their fingertips through an audio speaker.

Shane Kerwin's "Vibrato" invention connects to a speaker and relays the sounds of different instruments using unique vibrations for each one.
While vibrations can be felt on a regular speaker, it is impossible to distinguish the sound of each instrument.
With the Vibrato, a speaker is connected to five different finger pads. When music is played, it sends different vibrations to each of the finger pads, allowing the wearer to feel the difference between notes, rhythms and instrument combinations. Via CNN.
