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.
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 range where diaphragm travel is greatest.
Frequency is the most discussed and least understood variable in speaker cleaning. Here is the whole range, band by band, and what each one is actually capable of.
For a complete overview, see the physics behind the tone.
Small phone drivers cannot produce meaningful output here. The diaphragm is too small to move enough air, so the tone is inaudible or nearly so and does no work. Files advertised at very low frequencies often produce nothing on a phone — not because the file is wrong but because the hardware cannot reproduce it. On larger drivers (Bluetooth speakers, laptops) this band becomes usable and is sometimes optimal.
This is where speaker cleaning happens. Diaphragm travel is large enough to pump air meaningfully, and small drivers can reproduce it. Most smartphone resonances fall somewhere inside this range, which is why a sweep across it is more reliable than any fixed value. 165 Hz sits usefully low in the band and is the common default.
Still audible, still moving the diaphragm, but travel is dropping fast. Some marginal effect on very loose debris; essentially no effect on liquid held by surface tension.
Displacement is now measured in microns. There is sound but no useful airflow through the grille. This range is genuinely useful for testing — high frequencies are attenuated most by blockage, so a muffled 10 kHz tone reveals an obstruction clearly — but it cannot remove one.
Beyond the ceiling of human hearing, and beyond what almost any consumer speaker can reproduce. Tones advertised at 20 kHz, 30 kHz or 50 kHz cannot eject anything: the diaphragm barely moves, and in most cases the device produces nothing at all. The confusion comes from ultrasonic cleaning baths, which do use these frequencies — but they work by cavitation in a liquid the object is submerged in, which is a completely different mechanism.
Use 120–400 Hz to clean. Use around 10 kHz to test before and after. Ignore anything advertised above 20 kHz.
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.
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.
Our tool is great for water and dust, but it cannot fix physically blown speakers or electrical damage.
