Speaker Cleaner

About the Speaker Cleaner

Did your phone get wet, and now the speaker sounds muffled or crackly? Often a few drops of water are stuck in the speaker opening. This page plays a water eject sound: low, strong tones that make the speaker move a lot. The movement can push the water out.

Press Start and it plays for 30 seconds. Many people hear the sound get clearer after one or two runs.

It works on any phone, tablet or laptop with a browser. There is no app to install, and nothing is recorded or sent anywhere.

Features

• One tap — a big Start button and a ring that shows the time left
• 165 Hz pulses — the low tone most water eject tools use, in short bursts
• Low sweep — a slow sweep from 100 to 400 Hz, for a second try
• Steady tone — one long 165 Hz tone
• 30 seconds, 1 minute or 2 minutes — run it as long as you need
• Volume slider — full volume by default; turn it down for a laptop
• Screen stays on — the phone does not lock and stop the sound halfway

How does a water eject sound work?

A speaker makes sound by moving a thin cone back and forth. Low notes move it the most. At 165 Hz the cone pushes the air — and any water in front of it — about 165 times a second. Short bursts help too: every new start gives the drops another push.

Phones with water resistance are sealed inside, so the water usually sits in the outer opening of the speaker. That is the part this sound can clear. Some watches have a "water lock" feature that works the same way.

Important: what it can and cannot do

• It may help with a little water in the speaker opening. There is no promise — every phone is different.
• It cannot fix a speaker that is broken, or water inside the phone itself.
• If the phone fell into water, turn it off and let it dry first. Do not charge a wet phone.
• Never hold the speaker to your ear while it plays. It is loud on purpose.
• Do not put the phone in rice, use a hair dryer, or push anything into the speaker holes. Gentle shaking and air drying are safer.

Tips for the best result

• Remove headphones and turn Bluetooth off, so the sound comes out of the phone's own speaker.
• Turn the phone volume all the way up.
• Hold the phone with the speaker facing down, so the water can fall out.
• After each run, wipe the speaker opening with a soft, dry cloth.
• Run it two or three times. Try the low sweep if the pulses did not help.

How to use it

• Take off headphones and turn Bluetooth off
• Turn the phone volume all the way up
• Hold the phone with the speaker facing down
• Press Start — the sound plays for 30 seconds
• Wipe the speaker, then run it again if the sound is still muffled

Frequently asked questions

Does a water eject sound really work?

It can help when a few drops are stuck in the speaker opening, and many people hear a clearer sound after one or two runs. It does not work every time, and it cannot repair a damaged speaker.

Why 165 Hz?

Low tones make the speaker cone move the most, and about 165 Hz is a strong, low tone that small phone speakers can still play well. It is the tone most water eject tools use.

Does it work on iPhone and Android?

Yes. It plays in the browser, so it works on iPhone, Android, tablets and laptops. Turn the volume up and use the phone's own speaker, not headphones.

How long should I play it?

Start with 30 seconds. Wipe the speaker, then run it once or twice more if the sound is still muffled. You can choose 1 or 2 minutes too.

Can this damage my speaker?

It plays a normal tone, like loud music with a lot of bass. A phone can play it safely. If the sound starts to rattle badly, stop and turn the volume down.

My speaker still sounds bad. What now?

Let the phone dry in a warm, dry place for a few hours, speaker facing down. If the sound is still bad after a day, the speaker may be damaged — ask a repair shop.
