Free sound cleaner · no install

Water and dust don't belong in your speaker.

This speaker cleaner runs a calibrated water eject sound to clear a muffled speaker and get it back to full volume in under two minutes — no apps, no repair shop, no sharp objects near your ports. If your phone speaker is fixable at all, a sound cycle is the safest way to try.

  • 165 Hz water-ejection tone, same principle as Apple Watch
  • 0 downloads required
  • <2min average cycle
— Hz 00:00

Set your volume to maximum and hold the speaker face-down over a cloth before you start.

What's actually happening when it runs

No trick, no mystery frequency chart. Every speaker is a tiny diaphragm sitting in a mesh grille. Sound moving that diaphragm at the right rate physically shakes out what's trapped behind it.

  1. 1

    Pick a mode

    Water Ejector for liquid, Dust Buster for lint and grit, Full Clean to run both back to back.

  2. 2

    Speaker down, volume up

    Gravity does half the work — the tone does the rest. Rest the phone speaker-down on a soft cloth.

  3. 3

    Let the cycle finish

    The tone ramps smoothly and pulses at a rate tuned to move the diaphragm without straining it.

  4. 4

    Tap, test, repeat if needed

    A light tap against your palm clears the last of it. Play a sound to confirm — run it again if it's still muffled.

Why 165 Hz for water

A phone speaker cone resonates most efficiently within a narrow band. At roughly 165 Hz, the cone's excursion — how far it physically moves — is large enough to overcome the surface tension holding a water droplet against the mesh, without needing punishing volume. It's the same principle behind the water-eject shortcut built into Apple Watch and several waterproof action cameras.

Why higher frequencies for dust

Dry particles don't cling the way water does, so they respond better to faster vibration than to raw excursion. Dust Buster sweeps 3,000–9,000 Hz, a range that shakes the mesh fast enough to loosen lint and grit without the low rumble that water removal needs.

Questions people actually ask

What frequency removes water from a phone speaker?

Around 165 Hz — the same frequency Apple Watch uses for its built-in Water Eject shortcut. At that frequency the diaphragm moves with enough amplitude to push trapped droplets out of the mesh without needing dangerously high volume.

Is it safe to use sound to clean a speaker?

Yes, when volume and duration are controlled. This tool ramps volume up and down smoothly, caps every cycle at 30–75 seconds, and never exceeds a safe drive level, so there's no risk of overdriving the coil.

Does this work for dust as well as water?

Yes. Dust Buster sweeps 3,000–9,000 Hz, a range that shakes loose lint and fine debris more effectively than the low, steady pulse used for water.

Will this fix a speaker that's physically broken?

No. Sound-based cleaning only helps with water and debris trapped in the grille or mesh. If the coil is burned out or the diaphragm is torn, no tone will restore it — that needs a hardware repair. Not sure which case you're in? The fix my speaker guide walks through the symptoms.

Is a "clear speaker" tool the same as a sound cleaner?

Yes — "clear speaker," "sound cleaner," and "speaker cleaner" all describe the same idea: using a tone to clear whatever's muffling the sound. Some sites push a flat "10,000 Hz" tone for this; it's the wrong frequency for water specifically — see why in the blog.

Is this the same as a speaker test?

No. This tool cleans — it uses sound to physically dislodge water or dust from the grille. A speaker test is different: it checks whether your left and right channels work and runs a full frequency sweep to catch dead spots or rattling. If you're not sure your speaker is actually broken versus just blocked, run the speaker test first.

Does this work on iPhone and Android?

Yes. It runs entirely in your mobile browser using the Web Audio API — iPhone Safari, Android Chrome, and most modern mobile browsers all work. No app install needed.

Can I use this on a laptop or Bluetooth speaker?

It'll play through any connected output, but the effect is strongest on the small single-cone drivers in phones. Larger laptop or Bluetooth speakers rarely trap water the same way and respond less reliably.

How long does a cleaning cycle take?

Water Ejector runs 45 seconds, Dust Buster runs 30 seconds, and Full Clean chains both for about 75 seconds total. Most muffled speakers clear up in one or two cycles.

Will this drain my battery or damage my phone?

No. A single cycle uses about as much power as a 60-second video, and every frequency used is well within a phone speaker's normal operating range.

Muffled speaker, right now?

Skip back up, pick Water Ejector, and give it 45 seconds.
