Clear speaker

Muffled iPhone speaker? Hold it speaker-down and press Start. A 165 Hz tone clears water out of the grille in 45 seconds — and if it is dirt, not water, this page says so and tells you what does work.

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.

Wet or clogged? A 30-second test

“Clear speaker” covers two different problems, and only one of them clears with sound.

  • It went muffled all at once, after the phone got wet, and the grille looks clean under a torch: that is water in the mesh. The tone above clears it. Press Start.
  • It got quiet over weeks, the phone has not been wet, and a torch shows grey fluff in the holes: that is lint. No sound clears that — a soft dry toothbrush across the grille and a piece of Blu-Tack pressed on and peeled off do. Five minutes, no tools you do not own. Here is the full routine.
  • Both, which is common: run the tone first while the water is still liquid, then brush once it is dry.

How the clear speaker sound works

Water stays in a speaker grille because of surface tension: each droplet sits in a hole a fraction of a millimetre wide and will not fall out on its own. A speaker is a thin diaphragm on a coil, and at its resonant frequency — around 165 Hz for a phone — it moves the largest distance for the power put in. A few hundred pushes a second break the surface tension, and with the grille facing down, gravity takes it from there.

That is also why holding the phone the right way matters more than the sound itself. The tone plays through both speakers; gravity only helps the one pointing at the floor.

Things that sound like a blocked speaker and are not

Before anything else, thirty seconds on these — every one of them gets phones brought into repair shops for a “blocked speaker”:

  • AirPods or a Bluetooth speaker still connected somewhere in the house. Check the audio output in Control Center.
  • A case with a small cut-out sitting over the grille. Take it off and compare.
  • Reduce Loud Audio, in Settings → Sounds & Haptics → Headphone Safety.
  • The balance slider nudged to one side in Settings → Accessibility → Audio & Visual.
  • An EQ preset in Settings → Music that flattens everything.

A speaker that is quiet but clean-sounding is blocked. A speaker that crackles or buzzes on a dry, clean grille is damaged — that is a repair, not a clearing job.

Clear speaker — questions people ask

How do I clear my iPhone speaker?
If it went muffled after getting wet: volume to maximum, silent switch to ring, hold the speaker facing down and press Start above. The 165 Hz tone pushes the water out in 45 seconds. If it went muffled slowly with no water involved, the tone will not clear it — brush the grille with a soft dry toothbrush and press a piece of Blu-Tack on it to lift the lint.
What is the clear speaker sound?
A low tone, around 165 Hz, at which a phone speaker diaphragm moves the furthest. The movement breaks the surface tension holding water in the mesh and pushes the droplets out. It is the same sound the Apple Watch uses to clear its speaker after a swim. Higher-pitched “clear speaker” sounds on YouTube are louder to the ear but move the diaphragm less.
How do I know if my speaker is clogged or wet?
Timing and looks. Wet: it went muffled suddenly, after rain, a sink, a shower or a spill, and the holes look clean. Clogged: it got quieter over weeks, and a torch shows grey fluff in the holes. Wet clears with the tone; clogged clears with a brush. If you are not sure, run the tone first — it takes 45 seconds and cannot make lint worse.
Will the tone clear the speaker of dust?
Only loose dust sitting on the mesh, and only sometimes. Compacted lint does not vibrate out, whatever a “speaker clear” app claims. There is an honest page on speaker dust cleaning sound that explains what does and does not shift.
My speaker cleared but the other one is still muffled.
iPhones have two speakers and the tone plays through both, but gravity only helps the one facing down. Turn the phone over: for the earpiece, hold it screen-down with the top edge toward the floor and run it again. The top speaker cleaner page shows the hold.
Speaker still not clear after three runs and a brush?
Let it dry for a day and test again with a song at half and full volume. Crackling or buzzing on a dry, clean speaker means the diaphragm is damaged, and no sound or brush fixes that. It is one of the cheaper iPhone repairs; the repair cost guide has the numbers.
