In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. 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.
