Speaker Cleaner: Water Eject

Got water in your phone speaker? Speaker Cleaner plays a low 165 Hz tone that vibrates the speaker and helps push water out — the same idea used by smartwatches' water lock.

■ Water Eject

• 165 Hz pulsed tone, 30 / 60 / 120 seconds

• Vibration at the same time (optional)

• Intense mode: a low-to-mid sweep for stubborn water

■ Dust Cleaner

• A frequency sweep that shakes dust loose from the speaker grille

■ Tone Generator

• Any frequency from 20 Hz to 20,000 Hz

• Sine, square, triangle and sawtooth waves

• Left / right / both channels, volume, presets (incl. the 17.4 kHz mosquito tone)

■ Speaker Test

• Check left and right speakers

• 20 Hz – 20 kHz sweep to spot rattles and distortion

How to use: turn the volume all the way up, point the speaker down and press Start.
