About Speaker Care Lab

What we build

Speaker Care Lab provides free browser-based tools for speaker cleaning sounds, water-ejection assistance, call-speaker diagnosis, channel testing and controlled frequency generation. The tools run on the device after the user presses play. They do not require an account, audio upload or microphone access.

The site also provides troubleshooting guides that separate common causes of poor sound: moisture near an opening, dry debris, cases and screen protectors, Bluetooth routing, phone settings and physical damage. That separation helps users choose a relevant next step instead of repeatedly playing a tone that cannot address the real problem.

Our standard for claims

Sound vibration may help move droplets near a loudspeaker opening and may loosen light surface debris. It cannot prove that a phone is dry internally, remove every kind of dirt, repair corrosion or replace damaged hardware. We avoid universal success percentages, fabricated reviews and claims that one frequency is perfect for every phone.

Manufacturer instructions take priority over general advice. Relevant guides link to official Apple, Samsung and Google support material so users can compare our explanation with the instructions for their device.

Privacy by design

The tools either play locally hosted cleaning audio or generate test tones in the browser, depending on the feature. Speaker Care Lab does not need to hear, record or analyse the user’s microphone. No phone audio is uploaded to the site. Optional analytics may be introduced only with clear disclosure in the Privacy Policy.
