WringThe details
How water eject clears a cellphone speaker
A cellphone speaker is a tiny membrane behind a metal mesh. When water enters the speaker grille — after a shower, rain, a pool or a sink — droplets stay in the mesh and between it and the membrane, held by surface tension. Music sounds muffled because the water dampens the membrane and blocks the holes sound passes through.
The fix is mechanical. Drive the membrane at low frequencies and it moves air back and forth through the grille. Each stroke pushes droplets from behind; the pauses let them settle and merge. Eventually they are big enough to break surface tension and leave through the mesh. Apple Watch does this after a swim with a short burst of low tones. Wring's cycle uses the same idea, tuned for cellphones.
Why water eject uses two passes, not one tone
This page plays the same cycle as the app. The first half sweeps 110–900 Hz, where the bottom speaker moves the most air. The second sweeps 300–1500 Hz for the smaller earpiece, which cannot reproduce the lowest notes. Each sweep is gated: a short upward glide, silence and a downward glide. The on/off pattern matters more than volume — a steady hum just vibrates the water in place.
Is water eject safe for the speaker?
Yes. The tool uses audible frequencies at the speaker's normal playback level — the same level as a song at full volume. There is no ultrasound and nothing above 1.5 kHz in the cycle. Keep your cellphone away from your ear while it runs; it is deliberately loud.
What it cannot do
Water eject clears the speaker grille. It cannot dry water that has gone inside your cellphone. If it was submerged, turn it off, do not charge it, let it dry for a day and visit a repair shop if it acts up. Forget the bag of rice: rice absorbs almost no moisture from the air and its dust can cause problems in the port.
Why the browser version is quieter than the app
A web page can generate exactly the same sound but cannot control system volume. At 30%, the membrane moves a third as far and pushes a third as hard. The Wring app sets volume to 100% for the cycle, then restores your previous level. It also detects when your cellphone is face down, repeats if it still sounds muffled, and can run from Apple Watch or Siri on iOS — useful when your hands are wet.
Crackling rather than muffled sound?
Muffled sound suggests water. Crackling or buzzing usually means dust and lint have built up in the mesh. Water eject will not fix that; a higher-frequency dust cycle shakes particles loose instead. Wring includes a dust clean mode and a speaker test to check whether one speaker or both are affected.
Water eject shortcut vs this page vs the app
The popular Siri Shortcut plays one fixed 165 Hz tone at a fixed volume. It helps, but one frequency reaches only one speaker well and does not gate. This page runs the full two-pass cycle for free in any browser on iPhone or Android. The app adds volume control, positioning, repeat, dust mode, individual speaker tests and a health score; we recommend it if your cellphone gets wet more than once a year.
