iPhone 排水的科學原理為什麼 165Hz 是關鍵頻率
So, how does playing a simple sound get water out of your phone? We’re breaking down the physics of how 聲波 and vibrations force water out of your 喇叭.
重點摘要
- 165Hz 聲波 eject water by vibrating the 喇叭 membrane. Same principle as Apple Watch 水鎖
- Set volume to maximum and play for 1-2 minutes. Repeat 2-3 times for best results
- Apple recommends at least 5 hours of drying after water exposure, even after using sound ejection

1. What Exactly *Is* a “Water Eject” Sound?
A “water eject” sound is basically a tool that uses a specific low-frequency 聲波 to physically vibrate water droplets right out of your phone’s 喇叭 grill.
You’ve probably seen this on an Apple Watch — it has a built-in “Water Lock” feature that plays a tone to clear out its 喇叭 after a swim (Apple 官方支援). While your iPhone doesn’t have this feature baked in, apps and websites can replicate the exact same principle.
The magic number you’ll hear about most is 165Hz. This specific low-frequency tone makes the 喇叭 diaphragm vibrate powerfully, literally shaking and blasting water droplets off the 喇叭 mesh.
2. The Science: Why Does This Actually Work?
It’s not just magic — there are three key scientific reasons why playing a sound can get water out of your 喇叭.
The 3 Core Principles of 水抜き
- ① Powerful Vibrations
The 165Hz low-frequency 聲波 causes the 喇叭’s internal diaphragm to vibrate intensely. This physical movement directly transfers energy to the water droplets, pushing them outward.
- ② Breaking Surface Tension
Water clings to the tiny holes in your 喇叭 mesh because of surface tension. The force of the vibrations is strong enough to break that tension, allowing the droplets to be ‘flung’ away.
- ③ Resonance Amplification
Every physical object has a natural resonant frequency. 165Hz is close to the resonant frequency of the iPhone’s 喇叭 assembly, which means the vibrations get amplified, maximizing the water-clearing effect.
3. Comparing Your 水抜き Options
So, what’s the best way to do this? Let’s break down the options.
| Method | Effectiveness | Convenience | The Lowdown |
|---|---|---|---|
| Water Eject App | Excellent | Excellent | Diagnostics + Multiple Modes + Haptics |
| Water Eject Website | Good | Excellent | No install needed. Usually just one frequency. |
| YouTube Videos | Low | Good | Interrupted by ads. Audio quality varies. |
| Apple Watch Eject | Excellent | Excellent | Built-in, but for Apple Watch only. |
| Air Drying | Low | Slow | Takes 24-48 hours. Water can stay trapped in mesh. |
4. WaterKick’s 5 Smart Modes
WaterKick isn’t a one-size-fits-all tool. It has five modes for different situations. You start with ‘Diagnostic Mode’ to check your 喇叭’s condition, and it’ll suggest the best mode for the job.
Diagnostic Mode
Tests 喇叭 damage on a 4-level scale.
Soft Mode
For light moisture. Gentle and low-power.
Standard Mode
Your go-to for typical water exposure.
Powerful Mode
For serious soakings. Max power + haptics.
Repeat Mode
Continuous ejection. Set it and forget it overnight.

A good rule of thumb is to run it for 2-3 minutes at a time, for up to 5 or 6 cycles. Between each cycle, give your iPhone a gentle shake (喇叭-side down) to help gravity do its thing. Keep going until the WaterKick diagnostic tool gives you the all-clear.
Crank it up to max volume. The louder the sound, the stronger the vibrations, and the more effective it’ll be at pushing water out. Just, you know, don’t hold it right next to your ear.
沒有。 165Hz is well within the normal operating range for your 喇叭. Playing it for short bursts won’t cause any damage. WaterKick is designed with built-in timers and rest periods to keep everything safe.
Yep! The sound is a physical thing coming out of your 喇叭, so it keeps working even if you switch to another app. WaterKick fully supports background playback.
