200 Hz Speaker Agitation Cleaner

Play a 200 Hz tone to dislodge dried mud, dust, and sand from speaker grilles. Fast mechanical agitation frequency.

Start audio tests at low volume; stop for distortion. Tones cannot guarantee removal of water or repair internal damage. Do not charge a wet device.

Dropping a phone in beach sand can pack dry granules into the grille. 200 Hz vibrates the metal mesh rapidly, causing sand particles to bounce out.
