核心要点
- 扬声器振膜缝隙积水会因液体表面张力堵塞声孔，导致声音沉闷并产生严重杂音。
- 165Hz 频率恰好匹配微型扬声器振膜的机械固有共振点，产生最大的物理振幅位移。
- 6Hz 低频脉冲调制产生强劲空气推力，破坏水珠张力并将其推出防尘网。
- Web Audio API 生成纯净正弦波，避免了音频压缩带来的谐波失真。

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.
