The resin softens and the 50hz/60hz movement in the coils causes a "buzz" ...same with most buzzing or whining that comes out of old tvs and monitors ...you can open it up and paint the coils with nail varnish if it annoys you, or just ignore it ...it does suggest that your charger was cheap (cheap resin, cost-cutting production line etc.) or has had a lot of use - but it is not normally any cause for concern ...I've known TVs keep going for years after they start whining.
