Insert Coin: Soundlazer speaker plays music with extreme focus

Stefan Mileschin · 29th March 2012, 07:03

Here's a neat little project -- a parametric speaker that can only really be heard from the front. According to its inventor, the Soundlazer utilizes ultrasonic carrier waves, focusing its output in a single direction. The Soundlazer has a 20 to 30 foot range. You can hear it from head-on, but if you move to the side or shift the direction of the speaker a bit, the output drops off. The project has 52 days to go, to reach its goal of $48,000. Interested parties who pledge $175 or more will get a fully assembled speaker kit. To see the device in action, check out the video after the break.
