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.
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.
Laptop speakers collect dust easily. Select your laptop type and run a targeted cleaning cycle.
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.
Windows 7 reached end of mainstream and extended support in January 2020, and several audio problems on these machines trace back to that rather than to hardware.
For a complete overview, see our full guide: Fixing laptop and PC speakers.
Microsoft stopped issuing updates for Windows 7 in January 2020. Manufacturers stopped writing new audio drivers for it around the same time. That means driver issues on these machines cannot be resolved by updating — the fix is usually to find and reinstall the last driver the manufacturer released, which may only be available on their legacy support pages.
Control Panel → Sound (or right-click the speaker icon → Playback devices). Check that the built-in speakers are set as Default Device — a connected monitor or headset frequently takes it. Then Properties → Enhancements → Disable all sound effects, and Advanced → try 24-bit 48000 Hz.
Device Manager → Sound, video and game controllers. Uninstall the audio device, then restart — Windows reinstalls a generic driver. If the generic driver works but sounds poor, download the manufacturer's last Windows 7 audio package for your exact model. Realtek and Conexant were the common chipsets on machines of this era.
This matters for using any web-based tool. Modern Chrome and Firefox versions dropped Windows 7 support, so these machines are typically running older browser builds. The Web Audio API is supported in those older versions, so tone generation generally works — but if a page fails to run, browser age is a likely cause rather than the page.
A Windows 7-era laptop is well over a decade old. Speaker surrounds perish, solder joints fatigue, and connectors oxidise. Dust accumulation over that period is substantial — both in the grilles and in the cooling system, which has been drawing air through the chassis for years.
Power down. Soft dry brush across the grilles. Compressed air across, never into. Then three or four sweep cycles at 60–70 percent volume. Given the age, an internal clean of the heatsink is often worthwhile at the same time.
Worth mentioning separately: an internet-connected Windows 7 machine receives no security updates. That is a larger issue than the speakers.
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.
No — and this matters. The sound has to travel through the blocked speaker to do anything, so any connected Bluetooth or wired device defeats the purpose entirely. Disconnect everything first.
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. 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.
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.
