V&A Museum Sound. Display case with musical instruments
Resonant Bodies by Sound Artist Caroline Devine
Victoria And Albert Museum, London. Museum Sound Installation.
Musical instruments can be heard as well as seen.

Peel and Stick with our sticky pads. Wire to an amp. That's the installation complete.
Install at the bottom and inside the glass if you prefer. Easy to hide with vinyl decals.
And of course, the sound emits from both sides of resonant surfaces.

Attach a Feonic surface transducer to a resonant surface to create a high quality resonance speaker. A surface which envelops the listener in immersive sound. Powerful, portable, robust and easy to install (DIY skills only).

Ideal for heavy surfaces such as store windows and solid oak flooring and also lighter surfaces such as furniture, drywall / plasterboard and more. The low amplitude (excursion) ensures surfaces are not cracked or damaged by excessive vibration.

Resonance Speaker created from Resonant Surfaces

Plexiglass audio visual art installation
Plexiglass surfaces turned into invisible speakers for Audiovisual artwork SLABS by Adriano Abbado - Watch on Vimeo video
music by Stephanie L Ku

A resonant surface makes a pleasant sound when tapped.

The sound generated from the surface disperses through the panel. All will hear the same immersive surround sound at the same volume level. Avoids "too loud" hotspots.

Positioning is not as critical as with 'normal' speakers. The latter have to be in "line of sight". Painfully obvious. For sound art installations or museums the ability to hide a speaker can be critical:

"Loudspeakers inevitably say to the listener 'I am a loudspeaker', instead we want the sound to speak for itself".
Sound Designer Nick Ryan referring to his use of Feonic resonance speakers in a museum installation.

What's the differences between Feonic and alternative in wall speakers?

Table showing amplitude of micro vibrations
Micro Vibrations (low excursion) is good. High vibration (large excursion) from traditional speakers is bad. Latter can damage surfaces.

Feonic's unique micro-vibration amplitude is non damaging and suited to driving many structures. The amplitude of wasteful vibration other speakers create can be 300 times greater than an efficient Feonic Surface Transducer. These are potentially damaging vibrations. Additionally, Feonic vibration speaker drives can emit low and very high frequencies: 40Hz up to ultrasonic sound at around 22KHz. Feonic drives also have the advantage of being small, portable, removable and all weather resistant.

And depending on which solution you are going for, our technology is much simpler to install. You can fit our drives on, behind or under surfaces. Watch In Wall Speaker Installation videos and shudder at the effort, mess and expense.

How do Feonic vibration speakers work?
Our Smart Materials make other speakers sound dumb.

We use magnetostrictive Smart Materials to create wide frequency vibrations within surfaces. Developed for advanced military sonar technology, and in collaboration with the University of Hull. Feonic's award winning and multi patented technology is like no other vibration speaker product on the market. This is not a toy or gadget technology for cardboard boxes and the like.

Not all surface vibration speakers are the same. Superficially similar to a piezoelectric transducer, our products deliver high power and exceptional audio quality from the smallest vibrations. Vibrations up to 300 times smaller amplitude than alternatives. This micro vibration approach is a critical factor in avoiding damage to structures and to ensure high audio quality.

In what ways will Feonic Surface Speakers work better for me than traditional loudspeakers?

Feonic transducers activate large areas of windows, walls, floors or ceilings. In this window speaker example a single sound transducer powers a window. Delivering a controlled wall of sound over the entire surface area.

This allows passersby to hear the music or promotional message while they walk past the full length of the window. And at a constant volume without the sound getting annoyingly louder as they approach the speaker.

The consistent audio output is controllable to avoid noise pollution.

Problems with traditional loudspeaker technology

Traditional loudspeakers are subject to abuse from the weather, vandalism and theft. Wires are run through walls, either drilled through brickwork or window frames. Alternatively, Feonic drives are safe inside: fit without fuss in minutes.

The sound is louder the closer you get to the traditional loudspeaker - a "too loud" hotspot is the result. Conversely, the volume drops rapidly. To compensate for this traditional loudspeakers are often too loud, leading to noise pollution issues.

Too loud? And too quiet? Try Feonic technology for volume that is just right and for all your audience, not just those lucky enough to be situated in the volume or stereo sweet spot.
