Frequently Asked Questions

These questions address the specific recovery situation this page covers.

Why does the phone speaker rattle or vibrate after water exposure?

Rattling after water exposure usually means water has entered the space between the speaker membrane and the speaker housing. The water creates additional mass on the membrane and when audio plays the membrane vibrates against the trapped water rather than moving freely. This produces a rattling or resonant quality that is distinct from the muffled sound caused by water blocking the grille.

How is a rattling speaker different from a crackling speaker?

Crackling typically comes from the speaker membrane struggling to move through water, producing a rapid irregular noise. Rattling is usually a lower-frequency resonant sound that occurs consistently at specific audio frequencies, particularly bass notes. Both are symptoms of water in the speaker system but they indicate water in slightly different locations and may respond differently to the eject tone.

Will the eject tone fix a rattling speaker?

It is the best first step. The pulsed tone at 165 Hz is well-matched to the frequency range where rattling is most pronounced, so it both tests and treats the issue simultaneously. Run two to three cycles and check whether the rattling reduces between each cycle. A gradual improvement confirms water displacement is occurring. If the rattling does not improve after three sessions, passive drying for one to two hours before further attempts is recommended.
