I had two hands-down favorites at this year’s Consumer Electronics Show. One of them was the one that was everybody’s favorite: Palm’s upcoming Pre phone. The other was a little-known technology which I saw demoed in a private preview. It’s from a Boston-area startup called Emo Labs, and it’s a new technology for loudspeakers that called Edge Motion. Emo says that Edge Motion lets it build “invisible loudspeakers” for incorporation into TVs, computer displays, notebooks, and another devices with screens–and that its technology is the first all-new development in speaker design in decades. Judging from the sneak peek I saw, that isn’t hype.
