Frequently Asked Questions

These questions address the specific recovery situation this page covers.

What frequency is best for ejecting water from a phone speaker?

Frequencies in the 165 to 200 Hz range are most commonly used for speaker water ejection. This range produces sufficient physical vibration in the speaker membrane to displace water without being so high that it loses driving force or so low that it is inaudible or blocked by volume limiters. The Apple Watch uses a similar low-frequency tone for its built-in water eject feature.

Why does Fix My Speaker pulse the tone rather than play it continuously?

A pulsed tone alternates between on and off rapidly, which creates a repeated push-pull motion in the speaker cone. This rhythmic displacement is more effective at breaking the surface tension of water droplets than a steady continuous tone, which the water may resist by forming a stable film. The pulse pattern also reduces heat buildup in the voice coil during extended sessions.

Does using the wrong frequency damage the speaker?

Frequencies within the audible range and at reasonable volumes do not damage a healthy speaker. Speaker damage from frequency is typically caused by sustained high-volume resonance at the speaker's natural resonant frequency, which is a concern for large subwoofers rather than a small phone speaker. For water ejection purposes, the 100 to 300 Hz range at moderate volume is safe for repeated use.
