重要ポイント
- スピーカーグリルに入り込んだ水滴は表面張力によって留まり、音のこもりや音割れの原因になります。
- 165Hz の周波数は小型スピーカー振動板の固有共振周波数に一致し、最大の物理振幅を生み出します。
- 6Hz の LFO 変調によるパルス気流が液体の表面張力を打ち破り、外部へ押し出します。
- Web Audio API を用いて純粋な正弦波を生成するため、歪みのない安定した音波を再生できます。

01.The Physics of Acoustic Water Ejection: Why 165Hz Expels Moisture
When smartphones are exposed to water, liquid droplets adhere to the fine mesh protective grill over the speaker cavity. Acoustic resonance principles dictate that driving the speaker diaphragm at its fundamental resonant frequency (~165Hz) produces maximum physical cone displacement. The resulting pressurized air pulses force trapped water droplets outward through the mesh.
02.Pulsating Amplitude Modulation: Breaking Liquid Surface Tension
Continuous static tones can cause standing waves that hold water in place. By modulating the amplitude with a 6Hz sub-audible Low-Frequency Oscillator (LFO), the sound pressure rapidly ramps up and down 6 times per second. This rapid hammering effect overcomes liquid surface tension and expels droplets cleanly.
How to Eject Water from Phone Speakers
Step-by-step speaker water ejection instructions.
1
Set Device Volume to Maximum
Turn your smartphone or laptop volume to 100% to maximize acoustic air pressure.
2
Position Device Speaker Facing Downward
Hold or prop your phone with the speaker grill angled downward so gravity aids ejection.
3
Start Water Ejection Tone
Click "Start Cleaning" to play the 165Hz pulsating acoustic tone for 30 to 60 seconds.
4
Run Stereo Sound Balance Check
Play the Left and Right channel test sounds to confirm crystal clear audio playback with zero muffling.
Frequently Asked Questions
Run the tone for 30 to 60 seconds. If audio remains muffled, repeat the process 2-3 times while gently tapping the device on a soft towel.
