Water Eject Sound

Speaker sounding muffled after rain, a spill, or a swim? Play a pulsed 165 Hz tone - the same method Apple Watch uses - to physically push water out of the speaker cavity. Turn your volume to maximum, point the speaker down, and hit eject.

165 Hz

30-second pulsed ejection tone

Before you start: set your device volume to maximum, remove any case, and hold the device with the speaker pointing down so gravity helps the droplets leave.

How to eject water from your speaker

  1. Dry the outside first. Wipe the device and shake it gently, speaker facing down, to remove loose water.
  2. Max the volume, remove the case. The tone needs to move as much air as possible.
  3. Point the speaker down and press Eject Water. You should see or feel fine droplets leaving the speaker grille.
  4. Wipe and repeat 2-5 times until music sounds clear again.
  5. Let it finish air-drying for an hour before charging - the port needs to be dry even when the speaker is clear.

Why 165 Hz?

A speaker diaphragm moves furthest at low frequencies - but tiny phone and watch speakers lose the ability to play very low tones with any power. Around 165 Hz is the compromise both constraints agree on: deep enough for large, water-pushing excursion, high enough that a 10 mm speaker can still deliver it loudly. It is the frequency Apple chose for the Apple Watch Water Lock ejection chime, and the pulsing pattern helps break the surface tension holding droplets in place.

Water Eject FAQ

How does a water eject sound work?

A speaker is a diaphragm that moves air. Playing a strong low-frequency tone makes the diaphragm pump hard enough to physically push water droplets out of the speaker cavity - the same trick the Apple Watch Water Lock feature performs with a burst of roughly 165 Hz tone. It works on any device whose speaker can reproduce the tone: phones, watches, tablets, and laptops.

What frequency ejects water from a speaker?

Around 165 Hz is the sweet spot used by Apple Watch and most eject tools: low enough to produce large diaphragm excursion, high enough that small phone speakers can still reproduce it with power. This tool plays a pulsed 165 Hz sine wave for 30 seconds per run.

How many times should I run the water eject sound?

Run it 2-5 times, wiping away expelled droplets between runs, with the speaker facing down so gravity helps. Stop when the speaker sounds clear when you play music. If sound is still muffled after several runs and an hour of air-drying, moisture may be deeper in the device than the speaker cavity.

Does the water eject sound damage the speaker?

No - it is an ordinary audio signal well within what speakers are built to play. It is far gentler than the water itself, which can corrode contacts and leave mineral deposits if left to dry inside the cavity. Ejecting promptly is protective, not risky.

My phone was fully submerged - is this enough?

This tool only clears the speaker cavity. For submersion: power the device off, do not charge it until fully dry (liquid in the charging port plus current causes corrosion damage), wipe it down, and let it air-dry for several hours - port facing down. Skip the rice: studies show it dries no faster than open air and adds dust. Use the eject tone afterwards to clear the speaker itself.
