Soundlazer SNAP – The Directional Parametric Speaker
The Soundlazer directional audio project is the continuation of my first and very successful project here on Kickstarter. I developed the Soundlazer “Snap” during my quest to lower the cost of this amazing technology and give backers the opportunity to explore new possibilities in directional audio.
Parametric speakers like the Soundlazer are directional speaker systems. They use ultrasonic carrier waves to transmit audio to listeners in a focused beam of sound that acts like light from a laser. Generally speaking, only the person standing in front of a parametric speaker can hear the audio being transmitted. People to the sides of the directional audio source hear little or no sound.
