How to Amplify Your IPhone Speakers...with Your Hands!

I was listening to a song one day on an iPhone and didn't have any external speakers, so I came up with this method to boost an iPhone's speakers, using only your hands.

Start by holding the iPhone like this. You will notice that the speakers have been amplified immediately, and the sound will get slightly deeper.

Cup your left hand around the iPhone and right hand like in the picture. This boosts the sound quite a lot, and the sound gets much deeper. Make sure that there are no spaces between your fingers, as this will ruin the tone.

Adjust your hands and experiment to get the best tone. If someone has a variation of this technique that works better, feel free to put them in the comments!
