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.
30,000 Hz appears on a lot of speaker-cleaning pages and videos. It cannot clear water from a speaker, and most devices cannot even produce it. Here is what is really going on, and what to use instead.
For a complete overview, see our full guide: What the frequency actually does.
A 30,000 Hz tone cannot clear water from a speaker, and it cannot be heard by anyone. 30 kHz is ultrasonic — above the ceiling of human hearing, which tops out around 20 kHz in young adults with undamaged hearing.
Two separate problems make this frequency useless here. First, virtually no consumer phone, laptop or Bluetooth speaker can reproduce 30 kHz at all; the driver and the amplifier are both designed for the audible band and roll off sharply above it. If you play a 30,000 Hz file, in most cases nothing is being produced at all. Second, even if a device could produce it, diaphragm displacement at that frequency is effectively zero. Ejection depends on the cone physically travelling far enough to pump air against the trapped droplet. At 30 kHz there is no meaningful travel, so there is no pumping.
The confusion usually comes from ultrasonic cleaning baths, which genuinely use frequencies in this range. But those work by cavitation in a liquid the object is submerged in — a completely different mechanism that has nothing to do with a speaker vibrating in air.
The working range for speaker ejection is roughly 120–400 Hz. Around 165 Hz suits most smartphone drivers. Run the tool above with the grille facing down, at 70–80 percent volume, for 30–60 seconds per cycle.
Three popular fixes that do more harm than good. Rice is a weak desiccant — open moving air dries a device faster — and its starch dust migrates into ports and grilles, adding a blockage problem to a moisture problem. A hairdryer's heat can warp the thin diaphragm and pushes water vapour deeper into the chassis rather than out of it. Compressed air fired directly into a grille drives debris inward past the mesh, where you can no longer reach it. Room-temperature moving air and gravity are slower and genuinely better.
If the speaker turns out to be physically faulty, the decision is usually financial rather than technical. A speaker module is often an inexpensive part, but the labour of opening a modern adhesive-sealed phone is not, and if liquid reached the board the job expands from a swap to a clean-and-inspect. A reasonable rule of thumb: when a quoted repair approaches half the device's current resale value, replacement is usually the better call. Always ask for a written quote after inspection, before work begins.
Music is a poor diagnostic. A bass-heavy track masks exactly the mid and high frequency dullness that indicates remaining blockage, and a track you know well biases what you think you hear. Speech is far more revealing — a podcast, a voice memo, or a call on speakerphone. Consonants are the giveaway: if s and t sounds are soft or smeared, there is still something in the mesh.
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.
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.
