My main speaker damaged by water

My phone got in a bathroom and water spilled on it. Well actually it’s not J5 but J2 (2015) one. there has no J2 model so I used this instead, It’s too late to put in rice or silica gel because it passed an hour. Now it sounds a lot more quiet and sounded distorted and rather ear rape-like. I know it’s too late but however, since its obsolete i’m going to replace it with Huawei Y7 Pro but I will have to wait for my mom to buy it and send it to me from other city which is still TBA but will be sent in 2019. What can I do while waiting for that wacky phone?
