SpeakerCure Documentation — Phone Speaker Cleaning Guide & Technical Reference
From your first cleaning session to the acoustic physics behind how it works.
Getting Started
How to run your first cleaning session in under 60 seconds.
Open SpeakerCure
Visit speakercure.com in any browser — no download, no extension, no account required.
Raise Volume to Maximum
Set your device volume to 90–100%. This is the single most important step — low volume means weak acoustic pressure and poor results.
Position Your Device
Place your phone on a flat, hard surface with the speaker grille facing downward or sideways. If water-damaged, speaker-down helps gravity assist ejection.
Select a Mode
Choose Water Eject for liquid, Dust Removal for muffled audio, or Smart Diagnostic if unsure. Pro users can also access Deep Vibration and Manual Control.
Run the Full Cycle
Press Start and let the 2-minute cycle complete without interruption. For heavy damage, run 2–3 consecutive cycles.
How Acoustic Cleaning Works
The physics behind why sound waves clean better than cotton swabs.
Acoustic Speaker Cleaning is a non-invasive maintenance process that uses algorithmically generated sound frequencies to mechanically displace fluid, dust, and debris from micro-acoustic chambers — all without opening your device.
Mechanical Displacement: A low-frequency sine wave (e.g. 165 Hz) causes the speaker membrane to oscillate rapidly back and forth. This high-excursion movement acts like a miniature piston, creating alternating pressure zones that push particles outward through the grille.
Breaking Capillary Action: Water trapped in speaker mesh is held by surface tension. Our Water Eject mode alternates between 190 Hz and 210 Hz — frequencies calibrated specifically to overcome these cohesive forces, shattering droplet bonds and expelling liquid outward.
Anti-Static Dislodgement: Dust and lint cling to speaker mesh via static charge. A sustained 260 Hz tone modulated by a 4 Hz tremolo breaks this static grip, freeing micro-particles without requiring physical contact.
Water & Dust Restoration Modes
What each mode does and when to use it.
Alternates rapidly between 190 Hz and 210 Hz at maximum gain. Creates intense pressure bursts that push liquid droplets out of narrow speaker cavities. You may see tiny droplets spray from the grille — this is normal and expected.
Sustains a 260 Hz tone with a 4 Hz tremolo modulation. Designed to break static cling on fine dust, pocket lint, and microscopic debris without puncturing the membrane.
Sweeps through multiple frequency profiles automatically. Ideal when you're unsure of the cause — the system selects the optimal cleaning sequence based on measured impedance response.
Uses extended low-frequency bursts below 120 Hz for stubborn blockages that resist standard modes. Recommended for devices submerged for extended periods or with compacted debris.
For best results after a water incident: run Water Eject → wipe grille with a dry microfiber cloth → repeat 2–3 times → air dry for 30 minutes before testing audio.
Understanding Speaker Frequencies
Why different Hz ranges solve different problems.
| Frequency Range | Physical Effect | Used For |
|---|---|---|
| 100 – 250 Hz | High membrane displacement, strong pressure waves | Water ejection, heavy debris removal |
| 250 – 400 Hz | Balanced displacement + vibration | General dust removal, Smart Diagnostic |
| 2 kHz – 10 kHz | Rapid oscillation, low displacement | Speaker integrity diagnostics, Pro Diagnostic Test |
| 20 Hz – 20 kHz | Full spectrum sweep | Manual Frequency Control (Pro) |
Low frequencies (100–250 Hz) move more air and create more physical force — ideal for ejecting water and dislodging solid debris. High frequencies oscillate faster but with less membrane travel, making them better for diagnosing tonal accuracy and detecting "dead zones" in the speaker.
The Pro Speaker Diagnostic Test sweeps this entire spectrum, letting you hear exactly where your speaker drops off or distorts — giving you a real picture of hardware health.
Hardware & Audio Safety
Why SpeakerCure cannot damage your phone or ears.
All cleaning frequencies used by SpeakerCure (100–300 Hz in standard modes) fall well within the safe operating tolerances of modern smartphone speakers. These are the same acoustic principles used in the Apple Watch's built-in Water Lock feature.
In line with WHO guidelines for safe listening, output gain is capped via the Web Audio API to stay below the 85 dB short-exposure threshold. The system cannot physically generate damaging levels.
If your speaker is already physically torn, blown, or producing crackling before you start — begin at 50% volume and increase gradually. Acoustic cleaning cannot repair physical membrane damage.
The Rice Myth: Never place a wet phone in rice. Rice starch and dust enter the speaker grille and charging port, forming a paste when wet that causes permanent blockages. Always use acoustic ejection + air drying in a ventilated space instead.
No Foreign Objects: Do not insert needles, SIM tools, or compressed air into speaker holes. The membrane is thinner than a human hair — a single puncture permanently destroys sound quality.
Maintenance Best Practices
Keep your speaker clean before problems start.
Monthly Preventive Run
Run a 2-minute Smart Diagnostic once a month, even if audio sounds fine. Microscopic lint compacts slowly — catching it early prevents full blockages.
Post-Exposure Treatment
After rain, sweat, or any liquid contact — run Water Eject immediately, even if sound seems fine. Liquid travels deeper over time.
Wipe Between Cycles
After each cleaning cycle, gently wipe the speaker grille with a dry microfiber cloth. This removes ejected debris before the next cycle pushes it back in.
Avoid Cotton Swabs
Cotton fibers shed and lodge inside speaker cavities, worsening blockages. Use microfiber only.
Avoid Rice or Silica Bags on Speakers
Both release micro-particles that enter the grille. Use acoustic ejection followed by open-air drying.
