The magnet (or mechanism) holding down the lid seems to have broken

I dropped it from seat height and heard a crack as it hit the ground, now the lid has something rattling inside and the magnet (or whatever the mechanism is that holds the lid shut, magnetic or not) doesn’t keep the lid closed as well and opens often in my pocket. The lid opens with a slight swing, there seems to still be some retaining of the lid in place, but it’s far weaker than when I got it. Otherwise the issue does not affect the listening nor the charging and I wouldn’t mind if this was impossible to fix.
