Water-damaged speakers can be fixed at home through a number of different DIY techniques. One of the most popular techniques includes the use of a water eject application that can play a set of special high-intensity audios that makes your speakers vibrate and push out any water that has seeped up inside them. Another DIY technique is to dry the phone at room temperature while also putting it inside a clean bag of rice. The rice, when placed with the water-soaked speakers, can possibly soak up all the moisture and make your speakers work perfectly. However, make sure that while using dry rice to fix your speaker, make sure that the rice is free of any starchy white powder or debris.
