How to increase the volume on my iphone?

I really want some kind of way to increase the volume. This sound is just too low. Please help and thank you.

Added (1). I guess I didn't make it clear: I need a computer wiz to tell me how to enhance the volume on my iPhone beyond it's normal ability.

Buy a portable speaker.

Press the button on the side

I know you don't want to hear this, but Ill share two way:
1. Replace your phone for a new one ( here is a place you can go to do that http://myshoppingbusiness.com/powell5340 )

2. Get a really simple hear piece with a micro phone. That will help your volume. I did it too.

Hope it help Jake ( try here for really simple hear piece http://myshoppingbusiness.com/powell5340 )
