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.
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.
You have probably seen 20,000 Hz recommended as a speaker-cleaning frequency. It does not work, and this page explains why in plain terms — then points you at the frequency range that actually does.
For a complete overview, see our full guide: What the frequency actually does.
The direct answer: a 20,000 Hz tone will not eject water from your speaker. It is worth saying that plainly, because a great deal of material online implies the opposite.
20,000 Hz sits at the absolute upper limit of human hearing, and most adults cannot hear it at all — hearing above roughly 16,000 Hz declines steadily from your late teens onward. More importantly, it is far outside the range where the ejection mechanism works. Water is pushed out of a speaker by diaphragm displacement: the cone physically travels back and forth, and each stroke pumps air against the trapped liquid. At 20,000 Hz the diaphragm is vibrating twenty thousand times per second, but the distance it moves on each cycle is vanishingly small — microns rather than the meaningful travel you get at low frequencies. There is no pumping action, so there is nothing to push the water out.
Many phone speakers also simply cannot reproduce 20 kHz at any useful level. The driver is a few millimetres across and optimised for voice and midrange.
Useful ejection happens between roughly 120 Hz and 400 Hz, where the diaphragm travels its greatest distance. Around 165 Hz is a practical middle for typical smartphone drivers, and a sweep across the low band is more reliable than any single fixed tone because resonant frequency varies between devices. The tool above uses that range. Set volume to about 70–80 percent, point the grille downward, and run 30–60 second cycles.
Most phones have at least two audio outputs that fail independently. The earpiece at the top handles calls held against your ear. The loudspeaker at the bottom handles media and speakerphone. Some models add a third grille that is purely decorative and produces no sound at all. Testing each in isolation — a call in handset mode, then a music file on speaker — identifies the blocked opening in under a minute and stops you spending effort on a grille that was never the problem.
The grille you can see is not the speaker. Behind it sits a small acoustic chamber, then a fine mesh designed to keep dust out while letting air through, and only then the diaphragm itself. Liquid usually collects in the chamber rather than on the driver, which is good news — it means the water is on the outside of the mesh and can be pushed back out the way it came. It also explains why poking at a grille with a pin or a cotton bud is counterproductive: you are pushing debris past the mesh into a space you cannot reach.
The onset pattern is often more informative than the symptom. Sound that faded gradually over weeks or months points to debris accumulation — dust builds slowly. Sound that changed the instant the device got wet points to liquid. Sound that vanished the moment the device hit the floor points to a mechanical fault, and no amount of acoustic cleaning will address it. Being honest about which of the three happened saves a great deal of wasted effort.
IP67 and IP68 are laboratory ratings, tested with clean fresh water, at a specified depth, for a specified time, on a new device. They say nothing about soapy water, seawater, chlorinated water, or hot water — and nothing about a device whose adhesive seals have aged through two years of heat cycling and a screen replacement. Speaker grilles in particular are designed to let air move, so they are among the least sealed openings on any phone. A rated device that gets wet still deserves the same care as an unrated one.

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.
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.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
