Parts of a speaker in brief

Alright, in this short one we're just going to show you parts of the speaker. Here you actually have the speaker itself. This bit in the centre is called the dust cover. Basically stops bits of dust getting into the magnets. Here you have the coil. So if you notice on a speaker you have two wires, positive and negative. What happens is the positive will go around and round and round and round quite a few times, and then eventually that piece of wire will end up here as the negative and come out. Here is the spider. This here is actually attached just above the magnet. What that does is this actually keeps the coil in place in the right position in between the two magnets. So what happens... This moves up and down like so. Here is the chassis. This holds everything together. Terminals, positive, negative. Very often red and black. Here we can see a sticker, 8 ohms. And inside there you've got your magnets. North and south, not sure exactly which one's which. And inside there where my finger is...

You can just about see it as a gap, that's where the coil sits. And the coil should not touch either side, it has to sit perfectly in the middle of there. As soon as it starts rubbing against one of these magnets, eventually what will happen, it'll rub and rub and rub and just basically stop working. So this is another reason why you need to look after your speakers. Don't overpower them because remember, this thing... Won't last forever. Okay.
