Speaker cleaner

The water modes push the speaker cone hard with low loud pulses, which is the same trick the phone makers' own water eject shortcuts use; the dust modes shake at a quieter 2 kHz so they do not pound the cone. What this page cannot do: it cannot hear your speaker, measure how much water came out, or guarantee anything. If the sound stays muffled after a couple of cycles, let the device dry and try again later rather than pounding it more.
