Hello,
First I want to mention that I know very little about electronics. I've always wanted to learn about designing circuits and such, but I've never gotten around to it. Currently I'm working on a project where I've taken apart some simple computer speakers that will be relocated into a custom case I've built. I've realized that I'm missing a headphone jack and will not be able to use headphones, so I'm trying to fix this issue. I first started by trying to find a set of computer speakers that met all my requirements
#1 - small in size, simple L+R speakers
#2 - Push button On/Off and Volume control (no knobs as I will be relocating the controls to a place where knobs sticking out would be an eye sore.)
#3 - NOT USB speakers, the sound will not be coming from a computer.
#4 - A Headphone jack.
However after days of searching and finding speakers that almost fit the requirements, only to find out they are USB or don't have a headphone jack was very frustrating. So I decided to explore the option of modifying the speakers I have now and insert a headphone jack. My idea is as follows:
After the signal leaves the simple audio amp, it goes straight the the L+R speakers. I was thinking of instead sending it to 2 Transistors that in one position go to the speakers and on the other position go to the headphone jack. I was thinking that a simple tactile push button switch would work to control the transistors. As I stated above I don't know very much about electronics let alone diagrams. I guess I should start to explore what all the symbols mean etc. However for know I was wondering if these idea would work? It almost sounds too simple. If it would work, could someone help me find transistors that would work? If it is simple enough I was thinking of printing the basic circuit off on those projection slides with a printer, burning it to a PCB board, developing and then etching it as I've seen done in a video I once saw. Thanks for your time and anything you might contribute,

PS - is it possible to replace an those knob volume controls (I think potentiometers) with digital ones (push button volume control)? If so is it hard to do?
