About this test
When water or dust gets into the speaker, sound becomes muffled or crackly. This tool generates a low sine wave that makes the speaker membrane vibrate hard, pushing droplets out, the same principle as the water-eject feature on smartwatches.
The ideal frequency is usually between 150 Hz and 200 Hz. Keeping the speaker facing down lets gravity work together with the vibration.

Frequently asked questions
Can this damage my speaker?
At normal volume it is safe even at 100%. Avoid running it for many minutes non-stop at max volume and never with earphones in your ears.
Does it really remove water?
It helps expel most surface water. If the phone was submerged, power it off, dry it and avoid charging until you are sure it is dry inside.
