About Fix My Speaker
Fix My Speaker is a free, browser-based tool that plays controlled low-frequency audio through your device’s speaker to push out trapped water and loose debris. There is nothing to install and no account to create.
What the tool actually does
A speaker produces sound by moving a diaphragm back and forth. At low frequencies that diaphragm travels its greatest physical distance. Around 165 Hz, most small phone speakers reach a useful combination of excursion and force — enough to break the surface tension of water sitting in the speaker cavity and push droplets out through the grille. Apple uses the same principle in the Apple Watch water-ejection feature.
The deep-clean mode sweeps a range of low frequencies rather than holding one tone, which helps dislodge lint and dust that a single fixed frequency can miss.
What it cannot do
The tool clears blockage. It does not repair hardware. A torn diaphragm, a corroded contact, a failed amplifier or a disconnected cable will not respond to any tone. We keep a plain-language guide to the symptoms that mean you need a technician, because sending someone away with false hope is worse than telling them to stop.
Editorial approach
Guides on this site are written by James Whitfield, a mobile repair technician. We aim to be specific about what is established (low-frequency excursion moves liquid) and what is not (exact resonant frequencies vary by device, and no tone is universally optimal). Where a method is unsafe or ineffective — rice, hairdryers, compressed air fired into a grille — we say so.
Privacy
The tool runs entirely in your browser using the Web Audio API. It does not request microphone access, does not record anything, and does not upload audio. See our privacy policy for details.

How we test what we publish
Claims on this site fall into three categories, and we try to be clear about which is which. Established physics — that diaphragm displacement falls as frequency rises, or that surface tension has a breaking threshold — is stated plainly. Device-specific detail such as grille layouts, diagnostic dial codes and Liquid Contact Indicator locations is checked against manufacturer documentation. And anything that varies between devices, such as resonant frequency, is described as varying rather than given a single number.
Where a popular method does not work, we say so directly. Rice is a weak desiccant that adds starch dust to your ports. Compressed air fired into a grille drives debris past the dust mesh permanently. Frequencies advertised above 20 kHz cannot eject anything, because the diaphragm barely moves at those frequencies and most speakers cannot reproduce them at all.
Our corrections policy
If something here is factually wrong, we would rather hear about it than leave it published. Report the page and the error through the contact page and we will correct it. Substantive corrections are made to the page itself rather than appended as a note, so the article you read is the accurate version.
What we do not do
We are not a repair service and cannot diagnose an individual device remotely. We do not sell parts, take commissions on repairs, or accept payment for recommendations. The tool is free because generating a tone costs nothing to provide — it is a browser oscillator, not a service with running costs.
We also do not claim the tool fixes speakers. It clears blockage. A torn diaphragm, a corroded contact, a failed amplifier or a disconnected cable will not respond to any tone, and our guide to the symptoms of genuine hardware damage exists precisely so people stop rather than keep trying.
Who this site is for
Anyone whose speaker has suddenly gone muffled after contact with liquid, or has quietly degraded over months of pocket lint. The guides assume no technical background and explain the reason behind each step, because a step you understand is a step you will do properly. If you are a technician, the device-specific pages may still be useful as a quick reference for diagnostic codes and indicator locations.
