I'm talking like a true, bare bones one. I just want to brush up on the basics behind it, such as the various components behind one. Basically, I would like to see how hard they are to build as a personal experiment. Thanks for responding!

Thanks to both of you. I feel like an idiot forgetting about ground wires. I've been playing with simple circuits too long. And LIP I'll probably do what you said, you probably are much more experienced with science than me. Thanks again!

Hello engineers! So my left earbud got crushed, but everything else was ok. So I got this cazy idea to hook up the wiring to a speaker from a radio. The speaker works, I have tested it, and the wires for it are plainly labeled negative and positive. That is all fine and dandy. My problem stems from two facts: can my phone use a speaker like that if I get it properly wired, and I also am having trouble with the wiring in the earbud. They are the earbuds that came with my iPhone 5 and have worked fine (until being crushed). I cut the earbud off and discovered that there is three wires, not two like I had been expecting. So I have no idea what is negative positive and what the third wire does. I did some research and think I have found some solutions but the time I have spent here assures me somebody has an answer for me. I attached a photo of the wiring in the earbud. Whether I overlooked something stupid and just failed miserably, or it is an understandable problem, thank you for any help!

Hello Science Forums! New user here! As a new user, I ask that anybody tell me when I go astray from the etiquette around here. So, the reason I came here was my interest in science, particularly the crossroads between chemistry and electricity. So I have been researching hydrogen fuel cells, and I am NOT here to talk about how they are the future or how they are a bust and a fad. I was hoping someone could explain the basic outline of how these machines work. Whether I get my answer or not, thanks for helping out!
