Speaker Cleaner

What is this tool?

A tone generator built for clearing a blocked phone speaker. It plays a pulsing low-frequency tone that pushes water out of the grille, a sweeping tone that shakes dust loose, and a manual mode for finding the frequency your own phone resonates at. Nothing is recorded and nothing is uploaded — the sound is synthesised live on your device.

When to use it

  • Your phone got wet and calls or music now sound muffled
  • The speaker crackles or buzzes after a splash, a spill or a rainy walk
  • Dust or pocket lint has built up in the speaker grille over time
  • You want to check whether the left and right speakers still sound the same
  • You need a clean test tone to judge a speaker's clarity

How to use it

  1. 1Turn your phone's volume up to full
  2. 2Pick a mode — Water Eject for a wet speaker, Dust Shaker for a dusty one
  3. 3Hold the phone with the speaker pointing down so gravity helps the water out
  4. 4Press Start and let the tone run for the full session; wipe away any water that appears
  5. 5Use the test tones afterwards to check whether the sound is clear again

Frequently asked questions

Does playing a sound really remove water from a speaker?

Yes, within limits. A low-frequency tone moves the speaker's driver back and forth much further than music does, and that movement pushes droplets out of the grille. It is the same idea behind the water-eject feature on smartwatches. It shifts water sitting in and just behind the grille; it cannot do anything about liquid deeper inside the phone.

Why 165 Hz?

Low frequencies produce the largest cone movement, and pulsing the tone on and off adds a push-and-release action rather than a steady hum. Around 165 Hz is low enough to move a lot of air while still being something a small phone speaker can actually reproduce. Every phone differs, so the manual mode lets you hunt for the frequency yours buzzes hardest at.

Can this damage my speaker?

The output is capped below full scale for that reason, and a 15 to 60 second session at a sensible volume is well within what a phone speaker handles. If you hear crackling or a harsh rattle instead of a clean tone, that is the driver distorting — turn the volume down.

Will it vibrate my phone as well?

On Android, yes — the vibration motor pulses along with the water-eject tone. iPhones do not let a web page trigger vibration at all, so on iOS you get the tone only. The tone is what does the work either way.

Is any audio recorded or uploaded?

No. The tones are generated by your browser's own audio engine as they play. The tool never asks for microphone access, never records anything, and sends nothing to a server.
