”According to our sources, Apple had originally planned to incorporate what appears to be a second microphone in the recent version of the iPad mini.The above pictures for the iPad Mini prototype with 2 microphone is very interesting and similar to many rumors, for example I could remember there was a rumors claiming the iPad mini would have a rear mic—Apple must have decided to pull it at the last minute. And two, it explains all of those mini cases with the holes in their backs.
The photos show the prototype iPad mini with an extra hole centered, atop the rear of the device. It is unclear as to why Apple withheld the second microphone from the final product release, my guesses would be that it was axed out to cut down on cost, or to be preserved for a future generation iPad mini.”
Though the first generation iPad mini didn’t actually get the rear mic, both the iPhone 5 and current-gen iPod touch have them. And the word is that the iPad 5 will have one located right next to its rear camera, so we imagine the next-gen mini will too.
