It doesn’t come any thinner than this! Technology continues to amaze us with potent audio solutions such as this one from Emo Labs. They have created a flat, transparent “speakers” that go in front of the display. Warwick Audio and NXT Technologies, two British companies, and a Korean firm, Plasma & Ion Beam Corp., have similar plans of developing these film-thin speakers for better audio compatibility towards HDTV enjoyment.

“People are spending a lot of money on these TVs expecting to get great video and audio,” says Allan Evelyn, vice president of business development for Emo Labs. “And when they get their HDTV they are disappointed to discover their old CRT TV had much better sound.”

“It’s a question of physics,” says Aldo Cugnini, a digital technology consultant with AGC Systems, “and physics usually dictates that the bigger speakers have higher fidelity.”

Emo Labs uses a thin membrane made of polyethylene terephthalate (or PET, a plastic used in bottles) and two piezoelectric actuators. The actuators vibrate the membrane along the side, creating a force that is perpendicular to the motion. Emo Labs says it is negotiating with display manufacturers to embed its technology that users can see in TVs in the next nine months to a year.
