Made a few different cell phone amplifiers, these little devices really project the sound from a cell phone. Made these from scraps that I knew would turn into something useful.
Great projects! Thanks for sharing! When you designed these, did you have to take into account the exact locations of the speakers? I find it confusing that they call it stereo sound while the speaker is on the right bottom side and, in some models, one extra in the center top.
Harum, I build these in such a way that the holes will line up with most cell phones. You can customize for your particular phone but I never know who is going to get these so I make the holes a little bigger and leave wood in strategic places to support most phones. Thank for looking.
