Water Eject 101: How Sound Waves Clear Your Phone Speaker

Why Trapped Water Matters

Phone speakers rely on a thin membrane that vibrates to reproduce sound. When water or condensation lingers around the membrane, the vibration becomes dampened, resulting in muffled audio and distorted notifications. Leaving the liquid unattended can also corrode the copper voice coil, leading to permanent damage.

How Water Eject Works

Water Eject plays a sweeping tone between 150 Hz and 330 Hz. This frequency range is ideal because:

• Low frequencies travel farther through trapped liquid.
• The amplitude remains comfortable for human ears while still producing enough air pressure.
• Repeating the sweep prevents the formation of standing waves that might keep droplets in place.

The rapid oscillations push the membrane outward and create micro air bursts that shake water droplets loose. Gravity then helps the droplets exit the speaker grill.

Pre-flight Checklist

1. Disable silent mode so the tone can play at full volume.
2. Remove thick cases or accessories covering the speaker outlets.
3. Angle the speaker downwards to let gravity assist the process.
4. Wipe visible droplets gently with a lint-free cloth.

When to Repeat the Cycle

Most users see noticeable improvement after two cycles (30–40 seconds total). If you still hear distortion:

• Dry the exterior again and wait five minutes.
• Run the Water Eject sweep a third time.
• Consider leaving the device in a dry environment with gentle airflow.

Safety Notes

• Do not insert cotton swabs or toothpicks into the speaker mesh—they bend the membrane.
• Avoid blasting higher frequencies at extreme volume; you risk tearing the driver.
• If your device suffered saltwater exposure, rinse with distilled water first, then run Water Eject and allow the phone to dry completely.

Next Steps

Once the speaker sounds clean again, we recommend running a short maintenance sweep every few weeks, especially after beach trips or rainy commutes. Pair this with the full step-by-step tutorial inside the Water Eject tool for best results.
