How sound waves push water out of your speaker
Your phone speaker makes sound by vibrating a tiny diaphragm thousands of times per second. When water gets trapped behind the speaker mesh, it adds weight to that diaphragm — that’s the muffled, “underwater” sound you hear.
The fix uses the same physics in reverse: play a targeted low-frequency tone (around 165 Hz) and the diaphragm vibrates so violently that trapped droplets are physically ejected through the grille. This is exactly how Apple Watch’s Water Lock feature works after a swim — we’ve adapted the principle for any phone, laptop or Bluetooth speaker, in your browser.
Three modes, one goal: clear sound
💧 Water Eject · 165 Hz pulsed
A steady 165 Hz sine wave, pulsed 4 times per second. The pulsing creates sharper pressure spikes than a flat tone — better at breaking water surface tension on the mesh.
🌪️ Dust Clean · 250 Hz pulsed
Rhythmic 250 Hz bursts agitate lint, pocket dust and sand sealed into the grille holes, then the airflow carries them out.
✨ Deep Clean · 4 automatic stages
Stage 1: Water Eject (165 Hz, 60s) → Stage 2: Dust Sweep (2000 Hz pulses, 45s) → Stage 3: Resonance Sweep (120→220 Hz sweep, 45s) → Stage 4: Final Clear (165 Hz, 30s). Ends with a test tone so you can hear the difference.
What it can’t fix
Sound waves clear blockages — water, dust, lint. They cannot repair a torn diaphragm, corroded coil or dead amplifier chip. Rule of thumb: if the speaker is still completely silent after cleaning and a restart, it’s hardware — see the FAQ on when to visit a repair shop.
