# Speaker Rescue

> Speaker Rescue (https://www.speakerrescue.com) is an independent, browser-based speaker troubleshooting and audio-testing platform. It synthesizes mathematical acoustic frequencies (sine and triangle sweeps) via the W3C Web Audio API to help dislodge small water droplets and loose surface debris from smartphone speaker grilles.

Speaker Rescue is a browser software utility, not a physical hardware repair service. Sound waves drive physical speaker diaphragm excursion to overcome liquid capillary tension in acoustic meshes. Sound waves cannot dry sealed electrical connectors (e.g. USB-C/Lightning ports) or repair galvanic corrosion and circuit shorting.

## Tools

- [Water Eject Sound](https://www.speakerrescue.com/water-eject): Dedicated 165 Hz pulsing resonant sound utility with Quick (15s), Standard (30s), and Deep (60s) cycles to dislodge trapped water droplets from smartphone speakers.
- [Speaker Cleaner Sound](https://www.speakerrescue.com/speaker-cleaner-sound): Wide acoustic frequency sweep (100 Hz to 1200 Hz) to agitate loose dust, pocket lint, and debris across speaker mesh grilles.
- [Diagnostic Hub](https://www.speakerrescue.com): Flagship triage tool with problem selector (water, muffled, dust, charging port alerts) and 4-step safe speaker rescue procedure.
