According to an Apple patent application published by the United States Patent & Trademark Office and detailed by PatentlyApple, Apple is working to implement audio transducers in combination with multiple speakers to enable surround sound configurations on MacBook-like devices. Apple’s focus of the patent appears to be improving audio in mobile devices as speakers decrease in size to accommodate smaller and thinner form factors.

As detailed in the image to the right, one embodiment of the invention shows the use of several speakers and an audio transducer integrated into the bezel and enclosure of a MacBook. These configurations would allow, for example, the speakers embedded next to the display to handle high range frequencies, while the lower speakers would handle mid-range and the audio transducer the low-range. Additional speaker enclosures could be added to enable 3.1 or 4.1 surround sound configurations. Apple also stated the audio transducer could provide both low and mid-range frequencies, “essentially performing as a “subtweeter” for frequency ranges from 20-500 Hz and 500-1500 Hz.
