Rainbow Provides Sunshine and Wireless Sound
Edifier's wireless speaker system uses infrared to transmit sound.
Edifier Rainbow
Edifier’s Rainbow speaker system was nominated for a 2008 CES Innovations award.

Installing speakers all over the house makes beautiful music, but it’s certainly a project. Somewhere over this Rainbow, you’ll find the ability to stream audio—all without wires.

Edifier was first showing off its Rainbow speakers at this year’s Consumer Electronics Show. The system uses an IR transmitter, an IR receiver and a class D amp to produce sound.

The weird thing about this system is not the enclosures, which resemble those tubes that you put money into at the drive-up bank teller.  It’s that they are not included in the $199 price tag. That just gets you the transmitter, the receiver, and the dream that you may someday have wireless music.

Someone doesn’t care though; the Rainbow scored a nomination for the 2008 CES Innovations awards. It didn’t take the prize, but that’s still pretty impressive.
