Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.
Tap the button below. It plays a low‑frequency sound that vibrates the speaker and pushes trapped water and dust out of the grille. Turn your volume up to about 80%.
💡 Point the speaker downward so gravity helps the water escape. Repeat 2–3 times if needed.
Manually tune the exact Hz frequency for your speaker cleaning. Drag the slider to find the resonant frequency of your device.
Dry the outside of your phone first.
Let gravity help pull the water out.
Ensure audio plays through the phone's internal speakers.
Never use earbuds. Turn volume up, but 100% isn't required.
Our tool is designed to target the three most common speaker issues using precise acoustic frequencies. Whether your phone took a dive or just sounds muffled from pocket lint, here is how we fix it.
Clear trapped water from your phone in about 60 seconds. The steady 165 Hz vibration physically pushes trapped liquid out of the speaker mesh.
A steady 165 Hz tone — the sweet spot for maximum diaphragm travel — physically pushes trapped water out.
Use our deep clean mode to act as a dust remover. Sweeping low frequencies shake loose stubborn dirt, sand, and lint.
Sweeps across low frequencies (120–400 Hz) to shake loose lint, dust and stubborn droplets the single tone misses.
Act as a volume booster for muffled speakers. Clear out blockages to restore heavy sound, loud bass, and crisp audio.
A clean 440 Hz reference tone so you can hear whether your speaker sounds clear again after cleaning.
Perfectly safe. These are ordinary frequencies your speaker already plays during music. The tool never exceeds normal listening levels — it just concentrates the energy at the frequency that moves water best.
10 kHz sits inside human hearing, so unlike the ultrasonic claims you can at least tell it is playing. It still cannot clear a speaker, and the reason is worth understanding.
For a complete overview, see our full guide: What the frequency actually does.
At 10,000 Hz you will hear a thin, high tone — most adults under fifty can. That audibility misleads people into assuming something is happening. What matters mechanically is not whether you can hear it but how far the diaphragm travels on each cycle, and at 10 kHz that distance is measured in microns.
For a given drive level, diaphragm travel falls as frequency rises. At 150 Hz a small phone driver moves a comparatively large distance each cycle, which is enough to pump air against trapped liquid. At 10,000 Hz it is vibrating rapidly but barely moving. There is sound energy, but almost no air displacement through the grille — and displacement is the entire mechanism.
Two legitimate uses. It is a reasonable hearing test tone — if you cannot hear it at all and you are under forty, that is worth noting. And it is a useful speaker test: high frequencies expose blockage clearly, because debris in the mesh attenuates treble more than bass. A 10 kHz tone that sounds muffled or absent tells you there is an obstruction. It just cannot remove it.
Some cleaning tools play a descending sweep that starts high and ends low. People remember the high portion because it is more noticeable, and attribute the result to it. The work was done at the bottom of the sweep.
Roughly 120 to 400 Hz, with around 165 Hz a practical default for smartphone drivers. The tool above operates in that band. Set volume to 70–80 percent rather than maximum, point the grille downward, and run 30–60 second cycles.
Use 10 kHz as a before-and-after test, and a low-frequency cycle as the actual treatment. Play the high tone, note how muffled it sounds, run the low cycle, then play the high tone again. It is a more reliable progress check than music.
Stop. If three cycles produce no improvement at all, the cause is not blockage. Check the symptoms on our guide to when a sound tool will not help, and have the device inspected rather than continuing to run cycles.
Playing an audio file does not modify your device or open it, so the tool itself has no warranty implication. Note separately that liquid damage is usually excluded from standard warranty cover regardless.
No. The frequencies used sit inside the range your speaker already reproduces whenever you play music, and the tool runs at moderate volume rather than maximum. The one genuine caution is earbuds: never run ejection tones into in-ear devices while you are wearing them.
No. Around 70 to 80 percent is the practical sweet spot. Maximum volume on a restricted diaphragm produces distortion rather than more displacement, and adds avoidable stress to the driver.
Thirty to sixty seconds per cycle, repeated two or three times with short pauses. Running it continuously for many minutes adds nothing once the accessible liquid is out, and only heats the voice coil.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
