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.
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.
Ultrasonic cleaning is real, but it is not what a phone speaker does, and conflating the two leads people to use frequencies that cannot work. Here is the difference, and what to use on a blocked speaker.
For a complete overview, see choosing the right frequency.
Ultrasonic cleaning is real and effective — but it does not work the way a speaker tone works, and the two are often conflated in a way that leads people astray.
An ultrasonic cleaner submerges an object in a liquid bath and drives transducers at 20–80 kHz. The energy creates cavitation: microscopic bubbles form and collapse against the object's surface, lifting contamination away. This is what jewellers and repair technicians use, and it genuinely cleans corroded circuit boards. It requires the object to be immersed.
A speaker tone works by an entirely different mechanism. The device's own diaphragm moves back and forth in air, pumping trapped liquid outward through the grille. This requires large diaphragm travel, which only happens at low frequencies — the opposite end of the spectrum from ultrasound.
So a phone cannot perform ultrasonic cleaning on itself. It has no bath, no transducer, and its speaker cannot produce ultrasonic frequencies at any useful level. Files marketed as ultrasonic speaker cleaners either produce nothing audible at all, or quietly play a low-frequency tone under a misleading name.
Roughly 120–400 Hz, with around 165 Hz a good default for smartphone drivers. If your device has genuine corrosion inside — green or white residue, a tripped liquid indicator — that is a case for a technician's ultrasonic bath, and no tone will substitute for it.
Lint and dust are held by two forces that have nothing to do with surface tension: static charge, and simple mechanical wedging between mesh fibres. A single fixed frequency tends to settle particles into a stable position — the diaphragm reaches a steady state and the debris finds a spot where it is no longer being disturbed. Sweeping across a range denies it that resting point. It also explains why dust clearing usually needs four or five passes where water often clears in one, and why brushing the exterior grille with a dry, soft brush before you start makes a measurable difference.
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.
Expelled water sitting on the outside of the grille gets drawn back in on the next cycle's intake stroke. Running three cycles back to back without wiping can therefore recycle the same liquid rather than removing it. Keep a dry lint-free cloth to hand, stop after each cycle, blot the grille area, and only then start the next one. It is a small change in method that noticeably improves the outcome on a heavy soaking.
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.
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.
No. Rice is a poor desiccant — open moving air dries a device faster — and its starch dust migrates into the charging port, microphone holes and speaker grille, which can create a second problem on top of the first.
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.
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.
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.
