Apple Patents a Virtual Acoustic Audio System for MacBooks

Laptop speakers rarely impress. There's only so much a manufacturer can do to make them sound good, after all, and most people probably use headphones anyway. But the U.S. Patent and Trademark Office (USPTO) revealed on Tuesday that Apple has patented a new audio system to improve its MacBook speakers.

Part of the problem with laptop speakers is their proximity to each other. Many people are used to hearing things via stereo audio, especially since headphones and earbuds became so popular, but laptop speakers are often too close to clearly separate audio that's really only meant to be heard from one side or the other.

Apple's patent covered a virtual acoustic system that's supposed to address that issue. Rather than simply emitting sound from its speakers, a MacBook equipped with this technology would be able to make it seem like the sound came from somewhere else, almost like a technological ventriloquist. Apple said in the filing:

The patent covered numerous configurations of this virtual acoustic system that change how the crosstalk canceler is used--or if it's used at all--and how each of the paths are utilized. Check out the patent for more information on how Apple conceived of the system and what forms it might take in a real product. 

Apple filed the patent application, titled "System to move a virtual sound away from a listener using a crosstalk canceler," in August 2018. USPTO granted the patent on New Year's Eve. That means it could be a while before this system appears in a MacBook--assuming that Apple plans to continue developing it at all.
