Buzzing sound in lens that makes pics blurry

I bought this camera used on eBay it worked great for a year or two, I dropped it a few times since I bought it but recently it started making this buzzing sound in the lens and since the pics blur every time it does the buzz, I think it might be because of the focus. I have another camera, but this one takes better photos than the last one, so is there a way I can fix it without buying a new part?
