We already know all about the iPhone 4’s amazing noise-cancellation system for phone calls with its double microphone setup and today a patent reveals that Apple may be taking noise-cancellation a step further. Since we are talking about headsets and so there is no confusion, this is not noise-cancellation for listening to music but is noise-cancellation so you sound crystal clear on the phone calls you make. Patently Apple reports that Apple today published patents for two new headsets both with triple microphone action. Having two microphones on the iPhone 4 is already helpful, but three on a headset would be amazing and of course magical. Patently Apple describes the benefit of multiple microphones on mobile phones:
One of the headsets Apple is patented even reportedly includes a small boom and this would be extremely helpful. Users can use their microphone-equiped headsets for so many functions on iOS devices including phone calls on iPhones, FaceTime, voice recording, video recording, and of course Voice Control – which I never used. Getting into the design of these headsets, if you look at the image above you will see two different ones. The first looks nearly identical to the Apple earphones today and the second/bottom design looks like its straight out of 1999 with the external mic hanging on the side. Check out the patent in its entirety at Patently Apple.
