120 Hz Speaker Cleaner Tone

120 Hz speaker cleaner tone. Balanced low-frequency vibration for laptop speakers, iPads, and large smartphones.

Start audio tests at low volume; stop for distortion. Tones cannot guarantee removal of water or repair internal damage. Do not charge a wet device.

Laptops often route sound through keyboard grilles or display hinges. 120 Hz excites these internal acoustic waveguides to drain condensation.
