Some devices support the drainage function, which can be used to remove water from the speaker after swimming or from everyday exposure to moisture. The principle behind the drainage function involves playing sounds at specific frequencies to make the speaker vibrate, which helps expel the water that has entered the speaker, protecting it from water damage.
The methods to activate the drainage function are as follows:
1. Tap the drainage icon on the control panel of your device;
2. After certain water-related activities, the device will automatically enter the drainage process.
