Bought this recently --> http://www.ebay.com/itm/201004070756
It has a built in speaker. That's the main reason I bought it -- I wanted to see how they did that, along with how it's controlled (etc). The sound is tinny and a bit buzzy. Probably can't do much for the buzz (internal amp chip is a SMT version of the LM4871 that I really don't feel like replacing, and there's not really any room for piggying in extra components...) but the tinny speaker I might be able to fix.
What's in there now is a little oval thing that looks like you'd find it in a cheap old cell phone. The upshot is that it's on leads. I can replace that!
...but is there a cheap, small speaker that will fit this thing, that I can stuff in there?
I'll post photos of the player and its guts in a little bit, got a phone call to make first.
