4 Easy audio amplifier circuit

[@nik14116]

7:43 When you always use a puny 3.7v battery, your amp isn't much louder than the phone without. A 5v or 9v Supply would generate a much louder Audio-Signal. But when you use more voltage like 9v your amp would perhaps make some hum-noises. When this happens you need another Filter-Capacitor. You also need this higher voltage for driving big inch speakers like at 7:43. Otherwise the Speaker is as loud as your Phone. But your Videos are great i very like them.
