The Soundlazer parametric speaker

The Soundlazer project at kickstarter implements a parametric speaker hardware which allows to beam sound waves in the direction of a specific listener. This technology has been around since the 1960s but little advancement has been made using modern electronics components.

A parametric speaker uses ultrasonic carrier waves to transmit audio to listenersĀ a focused beam of sound, while people to the sides of the parametric source hear little or no sound. As the Soundlazer team offers the hardware as open source hackable solution, you can use your imagination to create fantastic new applications with it.
