Speaker Cleaner (Water Eject Sound)
Got your phone wet and now the speaker sounds muffled? Play a low 165 Hz tone, a slow sweep and short pulses that make the speaker cone vibrate and push droplets out through the grille. Nothing to install: it works in your phone's browser.
Last updated:
Ready: Auto mode, 165 Hz, 60 seconds. Turn your phone volume up first.
Your phone's own volume buttons still control the maximum.
- Dry the outside with a soft cloth and remove the case.
- Turn the volume up to 80-100% and disconnect headphones.
- Hold the speaker facing down or lay the phone screen-up with the speaker over the edge of a table.
- Press Start cleaning and let the full cycle play. You may see droplets on the grille.
- Wipe and repeat 2-3 times if the sound is still muffled, then let the phone air-dry.
How to use the Speaker Cleaner (Water Eject Sound)
- Prepare the phone: remove the case, unplug headphones and turn off Bluetooth audio.
- Turn the volume up to about 80-100% with the phone's volume buttons.
- Hold the speaker facing down so the water can drip out of the grille.
- Press Start cleaning. Auto mode plays a 165 Hz tone, a sweep and pulses for one minute.
- Wipe the grille and repeat 2-3 times if the sound is still muffled, then let the phone air-dry.
How a water eject sound pushes water out
A phone speaker sits behind a small chamber and a fine mesh grille. When water gets into that chamber, surface tension holds a film of droplets across the mesh and the sound turns muffled or crackly. A speaker makes sound by moving a thin membrane (the cone) back and forth. At the same loudness, a low note makes the cone travel much further than a high note, and that larger movement pumps air through the grille in short bursts, breaking the film and pushing droplets outwards.
That is why water eject tones sit low, around 150-300 Hz, rather than in the high range where the cone barely moves. Phone speakers are tiny, though, and their output falls away quickly below about 200-300 Hz, so going very low (like a subwoofer test at 40 Hz) just produces silence. 165 Hz is a practical middle ground, and the sweep covers the frequencies around it in case your phone resonates best at a slightly different pitch.
Which mode to use
| Mode | What it plays | Best for |
|---|---|---|
| Auto | 40% steady tone, 35% sweep, 25% pulses | The first run after the phone got wet |
| Tone | A constant tone at the chosen frequency (165 Hz by default) | Steady vibration while you hold the speaker facing down |
| Sweep | Glides slowly up and down the chosen range, 3 seconds each way | Phones and tablets whose speaker resonates at a different frequency |
| Pulse | 0.4 s bursts with 0.2 s pauses | Shaking loose the last droplets: each start gives the cone a sudden push |
Tips for a wet phone
- Power and charging: do not charge the phone while the charging port is wet. Many phones show a liquid detection warning; wait until it clears.
- Gravity helps: keep the speaker grille pointing down while the tone plays so water drips out instead of running back in.
- No heat, no rice: skip hair dryers and ovens. Air-dry the phone in a place with some airflow.
- Salt or sugary liquids: rinse with a little clean water only if your phone maker allows it, because dried residue can block the grille permanently.
- Still muffled after a day? Check the sound with the Left Right Speaker Test or the Speaker Frequency Response Test. If one speaker is still weak, it may need professional service.
Water resistance ratings such as IP67 and IP68 describe how well the inside of the phone is sealed. The speaker chamber in front of the seal is still open to the outside, which is why even water-resistant phones can sound muffled for a while after a swim.
Frequently asked questions
Does a water eject sound really work?
It can help with water trapped in the small cavity in front of a phone speaker. A loud low-frequency tone makes the speaker membrane move further than speech or music does, and that motion pushes droplets out through the grille. It does not remove water that has already got inside the phone, so it is not a repair for real water damage.
Why 165 Hz?
165 Hz is the frequency popularized by speaker-cleaning tones. It is low enough to make the speaker cone move a long way, but still high enough that small phone speakers can reproduce it loudly. If 165 Hz sounds weak on your device, try 200 Hz or the sweep, which passes through a range of frequencies.
How loud should the volume be?
Set the phone volume to about 80-100% and the tool volume to 90%. The motion of the speaker grows with loudness, so a quiet tone does little. Stop and lower the volume if you hear crackling, rattling or harsh distortion.
How many times should I run it?
One 1-minute cycle often clears the grille. If the sound is still muffled, wipe the speaker opening, wait a minute and run it 2 or 3 more times. If it is still muffled after the phone has dried for a day, the speaker may need service.
Can a speaker cleaner damage my speaker?
A low tone at normal maximum phone volume is within what the speaker is designed to play, and the tool fades in and out to avoid clicks. Very long runs at full volume are not needed, which is why the timer stops after at most 3 minutes.
Does it work for dust and lint too?
Vibration can loosen light dust in the grille, but packed lint or dirt usually needs gentle cleaning with a soft dry brush. Never push needles or pins into the speaker holes.
Should I put my wet phone in rice?
Phone makers including Apple advise against rice because small particles can get into the phone. They recommend tapping the phone gently with the connector facing down and leaving it to dry in a place with some airflow.
