How our tools work (methodology)

Straight answer: our speaker cleaner plays a carefully shaped low-frequency sound through your phone’s own speaker. The speaker’s diaphragm moves farthest at low frequencies, and that physical motion pushes trapped water droplets out of the grille and shakes loose light dust. It is the same principle smartwatches and some phones use for their built-in “water eject.”

How the water-eject sound works

At low frequencies (roughly 100–340 Hz) a speaker diaphragm makes its largest excursion — it moves in and out the most. We sweep through that band and play it in short bursts so water can re-settle and then be pushed again, which clears droplets more effectively than a single steady tone. Turning volume up increases the diaphragm’s movement and the effect.

What it can and cannot do

• Can: eject trapped water after splashes, rain or a brief dunk, and dislodge loose dust or lint muffling the grille.
• Cannot: repair a physically damaged, blown, or corroded speaker, or reverse liquid damage to internal components. If sound is still distorted after the water is gone, the hardware may need service.

How the Clarity Score is measured

When you tap Measure, the tool plays a fixed reference tone through your speaker and records it with your microphone, then analyses the captured audio’s frequency balance. A muffled speaker loses high-frequency energy, so a clearer result scores higher. This is a relative, on-device indicator using your own hardware — it is useful for comparing before vs. after on the same phone, not a calibrated laboratory measurement, and results vary with room noise and mic quality.

Safety

The tones are ordinary audio within the range your speaker already produces. Run it at a sensible volume; extremely high volume for long periods is unnecessary. Nothing you do here is sent anywhere — all audio processing happens in your browser.

Privacy

Every tool runs entirely on your device. Microphone audio is analysed locally and never uploaded or stored. There is no account and no tracking on tool pages.
