What Is the Water Eject Sound?
The water eject sound is a low-frequency tone, usually around 165 Hz, that makes a speaker diaphragm move quickly and with force. When water is trapped in the grille, this vibration acts like a tiny pump and moves droplets toward the outside. Our version alternates between 165 Hz and 210 Hz so more of the water is reached. You can read more about how a loudspeaker produces sound and why a trapped liquid muffles it.
How to Use the Water Eject Sound
- Dry the outside of the phone with a soft cloth.
- Place the phone with the speaker facing down on a tissue.
- Set volume to about 60 to 70 percent.
- Press start and run it for 30 seconds.
- Repeat up to three times, then play music to test the result.
Tip: if you are using headphones or Bluetooth, disconnect them first so the sound plays through the phone speaker.
Why the Phone Should Face Down
Gravity works with the vibration. When the speaker grille faces downward, droplets that are shaken loose fall out instead of settling back in. A paper tissue under the phone lets you see how much water leaves. If you see tiny dots on the tissue, the tool is working and you should repeat the round.
Water Eject vs Other Methods
Rice, hair dryers and compressed air are common myths that can make things worse. Heat can damage seals and adhesives and air pressure can push water deeper. Sound is non-contact and does not risk the internals. Pair it with air drying. For long exposure see our wet phone drying guide, and for dust use the speaker cleaner sound.

Frequently Asked Questions
What frequency is the water eject sound?
It is typically between 150 and 200 Hz. Our tool uses 165 Hz and 210 Hz in alternating pulses for better coverage.
How many times should I play it?
Two to three rounds of 30 seconds is enough in most cases, with a short pause in between.
Does it work if my phone is not water resistant?
It can still help clear water from the grille, but a phone without water resistance may have liquid inside. Power it off and get it checked if it was submerged.
Can the sound damage my speaker?
At moderate volume it is safe. Avoid maximum volume and stop if you hear buzzing or crackling.
