"We're quickly becoming a society of audiophiles.  Just think about the social media tools revolutionizing audio like Last.fm and Pandora, or the giant surround-sound systems we love to install in our homes.  \nBut while audio is becoming more dynamic, the actual speaker hardware hasn't changed much in years.  This is a problem as computers get smaller, TVs get thinner, and phones get more multimedia focused.\nOne company making some big buzz at the DEMO 2009 conference is Emo Labs, which revealed their \"invisible speakers\" to the applause of the audience.  The concept: instead of sound emerging from giant speakers, they come from thin, clear membranes that could completely redefine how you watch TV or use a computer.The technology they've developed is nothing short of impressive.  Dubbed \"Edge Motion,\" (the long form of Emo), the technology makes sound with sideways forces on an invisible membrane.  This vibration creates a full range sound that, from our vantage point, isn't distinguishable from even the regular speaker.  \nWe actually asked Jason Carlson, the CEO of Emo Labs, to give us a video demo.  Be sure to have your audio on for the full effect:\n\n\n\n\n\n\n\nOur inner geek couldn't help but be excited.  Imagine a notebook or a tablet with this technology.  No need to have a speaker, yet you could integrate full-featured sound.  The rumored Apple Tablet could play rich audio right in your hands without any plugs or headphones.  TV sound quality could be vastly improved, as many flatscreen TVs today have tiny speakers with limited strength.\nWe are impressed with Emo Labs and their invisible speakers and hope we see these things on the market."^^<http://www.w3.org/2001/XMLSchema#string>
