These are not just next-fashioned columns. In addition to the excellent look, they can boast of their revolutionary sound technology. Ultrasound, to be exact. The sound in such speakers is only in one direction, and not “diverges” in the room. In other words, listening to music, only you will hear it, and not the one who is in the same room with you.
Ultrasonic speakers Klang, generate a sound stream somewhere near the frequency of 30.000 Hz, which is a little more than what the human ear can perceive. When the sound wave touches the air, it is divided into three. One of the waves is an ordinary sound that we can hear, while the other two waves hold it back so that the sound cannot dissipate in space. Thus, the sound wave is directed only at you and the person sitting a meter or two from you will not hear anything. In other words, the music goes straight to your brain.
For clarity, we propose to watch the video in which it is told about ultrasound.
Can you imagine what open space is for your imagination? Now, the signs “DON'T MISS NO!” In museums and libraries will not concern you.
The problem is that the columns are still at the concept stage. But quite a working technology allows us to say with confidence that they still get to the store shelves.
