Smart speaker cleaning
A quick 4-step diagnostic calibrates a low-frequency sweep (165–230 Hz), then plays it to push debris out of your speaker.
How the cleaning sound works
- Turn your volume to maximum and remove any case.
- Hold the phone speaker-side down so loosened debris falls out.
- Press play and let the sound run for 30–60 seconds.
- Repeat if the audio is still muffled, or get the app for a stronger calibrated sound.
The cleaning sound is a low-frequency sweep (165–230 Hz) that vibrates the speaker diaphragm and pushes out water, dust and lint. The Speaker Wizard app plays a calibrated, full-power version with haptic vibration for the most thorough clean.
Frequently asked questions
What is the speaker cleaner sound?
It is a low-frequency tone, usually swept between 165 and 230 Hz, that vibrates the speaker just enough to push out water droplets and loosen dust and lint trapped in the grille.
What frequency cleans a speaker?
The 165–230 Hz range works best for phone speakers. It is low enough to move the diaphragm strongly without harming the speaker.
Does the cleaning sound actually work?
Yes. The vibration creates outward pressure that expels water and dislodges debris, and most people hear the audio clear up within a minute.
