For Best Ejection: Set device media volume to 100%, position speaker ports facing downward onto a paper towel, and run for 60 seconds.

How Does 165Hz Sound Eject Water?

When a smartphone is exposed to water, liquid surface tension (72.8 mN/m at room temperature) causes droplets to cling to the fine mesh covering the speaker opening. Because the droplets bridge across the micro-pores, they dampen the speaker cone and make audio sound muffled or quiet.

Smartphone micro-speakers achieve maximum mechanical displacement (stroke excursion) around 160Hz to 175Hz. By generating a pure, continuous 165Hz sine wave with rapid rhythmic pulses, the speaker diaphragm acts like an acoustic piston, producing bursts of positive air pressure that shatter the droplet's capillary bond and shake water free from the mesh.

💡

Best Practice Protocol: Turn media volume to 100%, disconnect headphones, point the speaker ports downward onto a soft absorbent towel, and run 2 to 3 cycles of 60 seconds.

Realistic Limitations: What Sound Waves Cannot Do

Cannot dry charging ports: Sound waves exit through open speaker apertures; they cannot displace liquid trapped against metallic USB-C or Lightning pins. See our Charging Port Guide.
Cannot remove liquid behind displays or cameras: Moisture trapped behind the screen indicates failed rubber adhesive seals.
Cannot fix physical hardware damage: If your speaker suffered a torn cone, deformed surround, or blown voice coil, acoustic vibrations cannot repair the physical components.
