Intro: Phone Amplifier Diy
Hello, I show an accessory for your phone that can be interesting. It's basically a stand for cell phone that amplifies the sound from the external speaker phone.
I tried it and it is curious to see that the result is really sensitive. Notice a significant volume change.
It is now an idea for a mono system, I'm in the process of making one for a tablet that has stereo output, I hope to show it soon.
A greeting and thanks for the visit.
