NXT puts sound on screen through thin clear speaker
Steve Bush NXT, the flat-panel loudspeaker company, has developed a thin transparent speaker that can be fitted over a display and produce stereo sound. In the first public demonstration, one was fitted to a slimline notebook computer, although the technology is said not to be limited to small screens. “It could be applied to a 60 inch television,” said company spokesman John Watson. The company claims that the technology, which it is calling SoundVu, is ready for use. “If someone takes it up and runs with it, it could see production before the end of the year,” said Watson. For NXT, it is too early to talk about licensees because last week’s demonstration was the first time anyone outside the company had experienced SoundVu in action. “It is an in-house development, we did not have a development partner,” said Watson. The display itself takes no part in the sound production, although Watson will not rule out using the display structure to make sound in the future. Instead the speaker sits in front of the display with an air gap. The speaker adds “a couple of millimetres, if that” to the display thickness, said Watson. Driving the speaker from the top or bottom allows stereo sound to be produced, although Watson thinks that it would also be possible by driving from one side only “but you would need a DSP”.
