Acoustic Amplifier for iPhone

Yesterday in my dance practice, one of my friends showed me a very interesting device that could amplify the music, alarm or any sound from the iPhone. It is really interesting. I checked it out and found out it. It is a product by GRIFFIN Technology.
The picture below shows how iPhone is placed attached to the AirCurve device and could be amplified to ~10dB. It was one piece of well design engineering application that could make a lot of money out of it. I am very impressed.
You could even charge and sync at the same time using Griffin dock cable or the charge and sync cable that come with the iPhone while playing music. I’ve just ordered one from the Amazon.co.uk (around £10 to £12)and I can’t wait for it to arrive. For more information on this gadget, check it out in
