Our teacher wants us to construct a speaker that can provide sound (that can be heard from anywhere within the classroom) when connected to wires that are hooked up to some sort of device. I'm unsure of where to start and where to get the supplies. Since we are on the magnetism course, I know that we need magnets and mabye coils. I also need some structure to hold my speaker together so that it stands by itself. Are there any links to instructions on where to build speakers from home materials (you cannot take parts from a speaker)? I found a couple of sites using google but they seem really complicated and this project is due on Monday for us. Thanks in adv..
