Can I fix the speakers in my Sony m 430 microcassette corder?

I barely found this sony m-430 microcassette-corder and it works for the most part except the sound quality. When I play back anything I’ve recorded it’s mostly just faded voices with an overpowering static sound. Anyone know what I can do? Or is it time to give up? Thank you!
