Future Macs could sport sensors that would detect users and adjust audio according — Apple World Today

This involves Macs with better built-in speakers and improved ability to send audio to external speakers. Especially interesting is that some of the patent graphics hint at Macs with built-in Face ID and body location (Body ID?) that could adjust sound based on where the user is standing relative to the desktop or laptop. All this would be accomplished by adding more sensors to Macs.

In the patent filing, Apple notes that electronic devices, such as computers, mobile phones, audio players, laptops, tablet computers, and TVs may have an integrated speaker or may be able to communicate with an audio output device. Additionally, such devices may also include a visual or video output device or communicate with a video display device. 

Apple says that such devices could offer improved audio or video output if the audio output is able to be adjusted to the environment, surroundings, circumstances, program, and/or environment. However, many audio and video output devices may require a user input or interaction in order to change a particular output or may not have variable output settings.
