Our main website provides a helpful guide to the many applications where our customers turn anything into a speaker. Use on resonant surfaces such as:

  • wooden panels or wooden floors
  • drywall / plasterboard wall and ceiling panels
  • sheet metal
  • plexiglass and other acrylic and plastic surfaces
  • and of course glass, including standalone or hanging panels for artworks; display cases; museum cabinets or heavy and even bomb-proof store window panes

Generally anything you can tap which results in a pleasing sound.

Feonic lead development of this powerful micro vibration technology and have done for over 15 years. Look for the Feonic Logo.

Feonic drives are similar to piezoelectric transducers but use a technology called Magnetostriction – learn more on wikipedia. This smart material technology emits micro vibrations with massive force but with very low amplitude (see our Wikipedia page). These micro vibrations mean that, unlike other superficially similar devices, Feonic vibration speakers won’t damage the surface you mount them on.

Micro Vibration Speakers – Fatigue and Stress

Frequency 80 Hz Frequency 300 Hz Frequency 500 Hz
Traditional Speaker c3000 μm c1500 μm c750 μm
Feonic Drive < 10 µm < 4 µm < 1 µm

Table showing how the Feonic drives create micro vibrations up to 750 times smaller than a typical cone speaker (as used in many in wall speakers). This indicates how a Feonic solution won’t cause structural fatigue or stress which could lead to damage to resonant surfaces

Additionally, unlike regular cone or box speakers, using Whispering Window won’t obstruct the view through glass. And because the sound is evenly distributed throughout the surface, you won’t have to crank it up to annoying levels.
People will be able to hear your messages while still being able to carry on a conversation and have a pleasant experience. Whispering Window sound is passive but it provides a dynamic attention grabbing tool.

Whispering Window speaker drives are small and unobtrusive. One or two drives are easily mounted on any glass surface (using a removable sticky pad) and are powered by an amplifier. Feonic can supply suitable amplifiers which can work from any sound source (CD Player, DVD Player, MP3 Player etc). You can of course use your own amplifier. No need to mount box loudspeakers outside with consequent drilling into exterior walls or window frames. No damage to delicate surfaces.
