The first personal sound projector was invented 2 октября, 2021


Engineers demonstrated the world’s first sound projector, which can track the movement of a particular person and create a sound sphere next to it to transfer individual audio messages.

The invention was presented at the International Technological Conference and the SigGraph 2019 exhibition. To create it, researchers from Sussek University used thin acoustic lenses made from special materials smaller than the length of the sound wave, and also used the principles of optical design.

During operation, the device uses integrated software to recognize persons, which is necessary to control the acoustic telescope and focusing sound on a moving object. The system tracks a person using a built-in inexpensive webcam and determines the distance between two acoustic lenses, creating a sound sphere with a diameter of about 6 cm in front of a person, reacting to its movement.

The technology is designed in such a way that it requires a user consent for its operation. This avoids obsessive and unwanted use.

According to engineers, in the manufacture of the projector, acoustic lenses were used, which can be printed on a 3D printer for $ 120 and the usual webcam for $ 12. They believe that with the help of technology, you can create a variety of useful devices, for example, to transfer personalized emergency messages in a crowd or sound equivalent of special effects without headphones.

The research team is currently working on the expansion of the system capabilities. They want to do so that the projector can simultaneously work in several directions and octaves.
