Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
TL084 circuits JFET Input Op-amp datasheet
TL084: low noise OP-AMP in cheap. Use JFET input. Why popular in audio & a lot of circuits: wide bandwidths and fast slew rates. Example:

LM386 Datasheet Low voltage audio power amplifier
You finished an audio circuit. But the sound is too weak. Many people use LM386 to increase sound up to a speaker. Why should you do it too? Some said to try it now. But...it is better. If you read LM386 Datasheet before.
