Fix iPhone Speaker

iPhone speaker cleaner

Muffled top or bottom iPhone speaker after water? This plays the 165 Hz iPhone water eject sound straight from Safari — no Shortcut to install, no app to trust.

0% Ready

Hold the phone speaker-down. Volume to maximum. Silent switch off.

  1. 1. Volume to max. iPhone: flip the silent switch to ring, or the tone is muted.
  2. 2. Speaker facing down. Gravity does half the work. Hold it over a towel.
  3. 3. Run 45 s, repeat. Works best while the speaker is still wet.

iPhone: the three things that stop the tone

  1. Silent switch. Orange showing means Safari’s audio is muted. Flip it to ring before pressing Start.
  2. Connected AirPods. If AirPods or any Bluetooth speaker is connected, the tone plays there, not from the iPhone. Open Control Center and switch audio output to iPhone, or put the AirPods in their case.
  3. Low volume. Press the volume-up button until the bar is full. The tone needs to move the speaker hard.

Top speaker or bottom speaker?

  • Bottom speaker — the grille beside the charging port. Music, videos, ringtones and speakerphone. Hold the phone upright, port facing the floor.
  • Top speaker (ear speaker / earpiece) — the thin slot above the screen. Phone calls sound muffled but music is fine. Hold the phone screen-down, top edge angled at the floor.

Run the tone once for each if you are not sure. Both play at the same time anyway; the orientation is what changes. The same holds for the ear speaker on Samsung, Pixel and other Android phones.

Muffled, crackling or distorted?

Three symptoms, three causes. Muffled after water is trapped water — the tone clears it. Crackling right after a spill is water on the diaphragm, and it usually goes with the second or third run; crackling on a phone that never got wet is debris or a torn cone. Distorted in one app only is software — restart and check the app’s EQ; distorted everywhere on a dry phone means the speaker is failing. Run the tone first in every case: it is free and takes 45 seconds, and most “broken” iPhone speakers after a spill are just wet.

Shortcut, YouTube video, or this?

All three play a similar tone. The differences are practical: a Shortcut has to be found, installed and trusted, and shared iCloud links keep dying. A YouTube video carries ads, the frequency is compressed, and someone can upload anything under that title. This page generates the tone itself, in Safari, with a 165 Hz fundamental, with nothing to install.

Does this really work?

Yes, for water in the speaker — and it is the same trick your smartwatch uses. A speaker is a paper-thin diaphragm on a coil. At 165 Hz the diaphragm of a phone speaker moves close to its largest excursion, so each cycle gives the water droplets sitting in the mesh a physical shove. Water only stays in the grille because of surface tension; a few hundred shoves a second break it, and the droplets get pushed out through the holes. Hold the speaker facing down and gravity finishes the job.

Apple Watch’s Water Lock does exactly this — it plays a tone and you can watch the droplets leave the grille. Samsung Galaxy Watch and several Android phones (OnePlus, Xiaomi) ship the same feature under “speaker cleaner”. This page just gives every phone the button.

What it does not do

  • Charging port. Sound does nothing there — the port has no diaphragm. Playing a tone over a “liquid detected” warning is wasted time. What actually works for the port.
  • Dust and lint. Loose dust may fall out during a run, but compacted pocket lint does not. For that, a soft dry toothbrush or a piece of Blu-Tack pressed gently on the grille beats any sound.
  • A blown speaker. If the sound is crackly and quiet without the phone ever getting wet, the voice coil is damaged. No tone fixes hardware.

Why this and not an app

The tone is generated by your browser’s Web Audio API with a 165 Hz fundamental — not a compressed MP3. It is deliberately not a bare sine: a phone speaker can barely reproduce a lone 165 Hz sine, so the wave carries its odd harmonics too, which is what makes it loud enough to matter while 165 Hz stays the strongest component. There is no app to install, no account, no subscription and no ads. Google Analytics counts page visits; what you do with the tool never leaves your device. It is free because there is nothing to sell.

Do not run the tone over and over on a speaker that is already dry. Pushing a dry diaphragm at full volume for minutes on end can loosen the voice coil and leave a permanent rattle. Three runs, then let it air-dry.

Questions people ask

Does the iPhone have a built-in water eject feature?
No. The Apple Watch has Water Lock, and iOS shows a “liquid detected” warning for the charging port, but there is no native button that plays a tone through the iPhone speaker. People who remember one used a Siri Shortcut. This page does the same thing with no setup.
Why does the Water Eject Shortcut not work for me?
Shortcuts shared on Reddit and RoutineHub break when iCloud links expire or when iOS blocks untrusted shortcuts. The tone here is generated by the browser, so there is nothing to install or trust.
Which iPhone speaker got wet?
iPhones have two: the bottom speaker beside the Lightning or USB-C port, and the earpiece speaker in the slot above the screen. Music and speakerphone use both; calls use only the earpiece. Point whichever one sounds muffled at the floor while the tone plays.
The tone is silent on my iPhone. What is wrong?
The side silent switch. While it shows orange, Safari mutes web audio. Flip it to ring, check the volume buttons are at maximum, and press Start again. Also make sure no AirPods are connected — the sound would go to them.
Will this damage my iPhone speaker?
Not in normal use. The tone is a clean 165 Hz signal at the volume your iPhone already plays music, and it stops after 45 seconds. Avoid running it more than three times in a row on a speaker that is already dry.
How do I clean the top speaker on my iPhone?
The top speaker — also called the upper speaker, ear speaker or earpiece — is the slot above the screen. For water: hold the phone screen-down with the top edge toward the floor and run the tone. For lint: brush the slot with a soft, dry toothbrush and make sure your screen protector is not covering it. An iPhone top speaker cleaner is the same tone as the bottom one; only the way you hold the phone changes.
What is the best sound to clear iPhone speakers?
A 165 Hz tone, played at full volume with the speaker facing down. It is the frequency the Apple Watch uses and the one people report clearing water most reliably. Higher-pitched “speaker cleaner” sounds are louder but move the diaphragm less; this page keeps 165 Hz as the fundamental and adds harmonics so it is still loud on a phone.
Does it work on iPhone 15, 16 and 17?
Yes. Every iPhone since the 7 is water resistant and every one has the same kind of micro-speaker, so the same frequency applies. Newer models simply need fewer runs because their grilles drain better.
