Want to astonish your guests with music from the empty walls or showcase objects of your living room? Well, inventor Richard Haberkern has designed a great low-cost parametric speaker, dubbed the Soundlazer, which can direct sound to a particular point, so like you can do with the laser beams. What Haberkern brags the-never-before-possible-parametric-speaker-technology is able to bring lucid music from your walls, showcase objects or anywhere else the speakers are into.
The Soundlazer makes use of 39 individual high frequency ultrasonic beams. Yes, the technology is based on ultrasonic beams that travel through the air and hit the objects ahead to let off the sound as it is from the objects. The parametric speaker produces a 2-foot diameter beam and it can move to 30 feet on a direction. Any hard object that prevents the ultrasonic beams on their war reproduces the sound in a stunning clarity.
Parametric speakers have been there for a long time. But, to get a standard parametric speaker, you will have to pay at least $3,000. According to the designer of Soundlazer, his project costs much less. The circuit board of the Soundlazer just contains an Analog Devices ADAU1701 Digital Signal Processor, 39 piezo ultrasonic transducers and some other tiny components.
The creator of the project is looking for financial support on Kickstarter with a pledged goal of $48,000. Haberkern offers that once the project is successful, Soundlazer units can be built for low cost, thus many industries, advertisers and all others can get the advanced parametric speaker for a low price.
