Say what? A surprisingly simple way to amplify your iPhone

You've probably seen a lot of fancy devices promising to boost the sound of your iPhone. It turns out there's at least one simple acoustical solution out there to consider. The AudioGlove iPhone case works by simply creating an acoustic channel around your phone's microphone.

Inventor Falco Freeman actually uses the "flaw" in the iPhone's acoustical design — the fact that the microphone is small and faces downward in providing the solution. He's created the AudioGlove case for the iPhone that works by simply sliding out the bottom of the case to create a natural sound channel around the mic.

It not only amplifies the sound coming out of the phone, but the sound going in. It directs the users voice and weeds out background noise by channeling it into the microphone. Sound coming out is projected to the listen so there's less distortion. The dual function creates a better experience on both ends.

It's such a simple fix it's hard to believe it could work, but the numbers are impressive. The AudioCase was tested by Dolby's sound labs, and it was found that it enhanced sound volume in the range of 20%.

The case is made from a durable polycarbonate so it looks good while functioning and as it happens, also protects the phone itself. It's available for the iPhone 4/4S and 3G/3GS (iPhone 5 version to be ready this fall) and comes in a variety of colors.

Freeman's cases are available via Kickstarter for $35, with discounts available. He's also offering a custom stand to go with the cases for the iPhone 4/4S case, which is great when you need to go hands-free.

There's plenty of time to get in on the ground floor as the project has reached just under a third of their financial goal with 31 days to go.
