A new patent awarded to Apple today suggests that the company’s audio plans for future iPhones may go beyond reportedly ditching the 3.5mm headphone socket in favor of Lightning and Bluetooth. The patent is very densely-worded, but seemingly describes a method of getting higher-quality and higher-volume audio from speakers built into slimmer devices.
Apple’s statement of the problem is clear enough.
Given the area constraints imposed on many portable electronic devices, it is increasingly difficult to provide high-quality audio sound output and pickup without hindering the ability to make portable electronic devices smaller and thinner. Consequently, there is a need for improved approaches to provide high-quality audio sound output and/or pickup from portable electronic devices as they get smaller and thinner.
The language describing Apple’s proposed solution is less clear, but from a combination of this and the accompanying diagrams, I at least have a working theory of what is being suggested …
