Directional Speakers

by on Jan.25, 2013, under My gadgets

This speaker modulates audible sound on ultrasonic signal and send the modulated sound in a beam through the array of piezo speakers. The sound will be demodulated with the non-linearity of air itself and can be heard right in front of  the speaker. The case is made by laser-cut cherry wood. A small laser diode is used to indicate the path of sound.
