What the phone speaker cleaner sound is
The phone speaker cleaner sound is a low, steady hum with a fast pulse on top. It is not music and it is not pleasant to listen to. It is built to make the speaker cone move as far as it can, because that movement is what pushes water and dust out of the grille.
On this page the sound is generated live by your browser instead of being a recorded audio file. That means no compression, no loading time, and the exact frequency every time.
Which sound should you play?
Choose the mode that matches what happened to your phone.
- Phone got wet and sounds muffled: Water, 165 Hz pulse, 60 seconds.
- Volume dropped slowly over weeks: Dust, 200 to 1200 Hz sweep, 60 seconds.
- Tried both and it is still dull: Deep clean, 2 minutes.
- Callers sound quiet during phone calls: Ear speaker, 400 to 1500 Hz.
- You want a specific frequency: Manual, 80 to 1000 Hz.
Why 165 Hz?
Lower frequencies move the cone further, but phone speakers are tiny and cannot play very deep bass loudly. Around 165 Hz is the practical sweet spot: deep enough for long cone travel, high enough that a phone speaker can still play it at full strength.
Larger speakers, such as those in tablets and laptops, can go lower. In Manual mode try 100 to 140 Hz for those devices.
How long to play the sound
One 60 second cycle is enough in most cases. Watch the grille while it plays. If you see fine mist or droplets, the sound is working, so run another cycle until nothing more comes out. Give the speaker a short rest between runs.
