How SpeakerDryer Works

Understanding the science behind using sound waves to clean your smartphone speakers.

The Acoustic Principle

SpeakerDryer.net utilizes a specific acoustic phenomenon known as Resonant Frequency Excitation. Smartphone speakers are designed to move air to create sound, but they can also move other light substances, including liquid water droplets and fine dust particles.

Why 165Hz?

Through extensive testing, we identified 165Hz as the optimal frequency for most modern smartphone speaker modules (including iPhones and Samsung Galaxy devices). This low-frequency bass tone creates a standing wave pattern with high amplitude (vibration strength) but low pitch.

At this frequency, the speaker cone vibrates with maximum excursion, generating significant air pressure changes. These pressure waves break the surface tension of water droplets trapped in the mesh, effectively "blowing" them out of the grille.

The Water Ejection Process

The "Water Eject" mode operates in three phases:

1. Initial Pulse: Short bursts of sound loosen water droplets from the internal speaker walls.
2. Sustained Tone: A continuous 165Hz wave pushes the water towards the grille opening.
3. Clearing Cycle: Alternating frequencies ensure that water trapped in corners or smaller mesh holes is dislodged.

Dust Cleaning Mode

Unlike water, dust particles are dry and often cling due to static electricity. Our "Dust Cleaner" mode uses a variable high-frequency pulse (sweeping from 800Hz to 2000Hz).

These rapid vibrations create a "shaking" effect that destabilizes dust and lint, causing it to fall out of the grille or become loose enough to be blown away by a subsequent bass tone.
