Harman patented flying robotic speakers

Imagine you're using a VR headset and as a car races past, you hear it whip from left to right. Only the sound literally moves from left to right because it's coming from a robotic speaker that zips across the room. From the looks of a new patent, audio company Harman is dreaming up speakers that would do just that. This week, the US Patent Office awarded Harman a patent for a "mobile speaker system for virtual reality environments." According to the patent, the company would map VR soundscapes to robotic speakers, which would either drive or fly (thanks to quadcopters) to better represent the distance, direction and movement of sounds.
