Sound Installation Invisible Speakers for your Artwork, Gallery or Exhibition.
Ideal for intimate sound from Museum Display Cases

As a Sound Artist you want people to focus on your message, concepts and ideas. The last thing you want is for people to see a loudspeaker mounted on a wall with wires or a distracting dirty grille. Team with Feonic so people focus on your artwork.

Our Invisible Speakers solve the problem of how to install concealed speakers. Perfect to audio enhance the artwork or an entire exhibition space or museum display case. Suitable for inside buildings without creating echoes or "too loud" hotspots. And robust enough for outside in hostile environments. All without bulky and obtrusive speaker boxes cluttering up your artistic design.

LOUDSPEAKERS SHOUT THEIR PRESENCE:
let your art installation do the talking

Picture Frame Speakers - Turn your favourite artwork into a speaker

Take a look at this sound art installation project by Adriana Paice.

"...as people run their fingertips over the contours of the silk embroidery, couched with conductive silver thread, they complete the circuit. And trigger a fragment of poetry that plays through the Feonic speaker attached to the rear of the stitched piece."

An alternative approach to traditional loudspeakers is to convert an artwork into a speaker. The picture and frame hide the drives. This may be appropriate for a temporary art installation which requires sound. Or where attaching a device to a wall panel is not appropriate or practical. Additionally, this technique ensures the sound is generated directly from the artwork itself. Creating an immersive experience that is effectively wireless and without speaker boxes or grilles.


Surface Speaker Transducer creating a Resonance Speaker

The key is to turn a panel surface into a resonance speaker. Think of a guitar or violin. Tiny vibrations from the strings are amplified by the wooden surface. Our technology works with an audio signal from a music player like an mp3 player, DVD player or from a microphone. When attached to a resonant surface the micro-vibrations emit sound over the entire surface.

Both sides of the material emit the sound signal. So install the audio transducer inside an artwork or museum display case. You could even mount one of our smaller drives inside a musical instrument like a guitar, piano or cello. Play a virtuoso performance using the actual instrument surface for a more realistic audio experience.

For more delicate instruments, attach one of our surface transducers to the inside of a museum display case. The glass will make an excellent surface speaker. Hide the audio transducer itself behind a graphic. Again, the sound needn't be too loud, only those close to the glass will hear.



Robust, Reliable, Weatherproof, Vandalproof. Easy to Install, Remove and Re-Position

Additionally, you can avoid extensive and expensive installation procedures. For surfaces such as drywall (plasterboard), metal, wood, grp etc simply screw mount our sound transducers to the surface. Both sides of that panel become the speaker. There is nothing to see. Wireless as wires are behind panels. For exterior artworks there is nothing visible to vandalise.

The drives are robust and weatherproof as standard, but can be waterproof too. The transducer can be safe and dry inside an object or case or behind a window. Drives are often used on decks in gardens, subject to extremes of damp, humidity, heat, cold and even work when covered in snow.

Museum Maritime Exhibit walkway becomes a speaker

"I'm a big fan of Feonic F1.3's and have used them many times to great effect.

In this case the devices allowed us to invisibly transform a 10 meter long wooden walkway into a multichannel speaker array.
As the walkway runs alongside the boat and the sound emanates from the entire surface of its structure I believe listeners are able to associate sound with the exhibit more directly and more intuitively than if the sound were to be provided by a loudspeaker.

Loudspeakers inevitably say to the listener 'I am a loudspeaker', instead we wanted the sound to speak for itself".

Glass and Acrylic Surface Speakers

Glass too makes an excellent surface for our sound transducer technology. Ideal for a display case or window protecting your artwork. With sound, you can help reduce the perception of a glass barrier between the viewer and the artwork or exhibit.

Mount our transducers using a sticky pad to make a permanent or temporary bond to the glass. Leave in place for years or remove from the glass when your art exhibition is over.


Massive Power : Micro Vibration : Zero Cracking of Surfaces

Our Invisible Speaker technology uses extremely powerful micro-vibrations. Up to 300 times smaller in amplitude than other less optimal invisible speaker solutions. This ensures the surfaces are not damaged or cracked in any way.

The key is that the extreme power of the materials we use to power our drives causes the entire panel to emit sound. A speaker diaphragm is typically 4 to 8 inches across. Our approach creates a diaphragm perhaps 30 to 50 times bigger. This sends waves of sound from the surface to fill a room with sound. This avoids the point source line of sight required for traditional cone speakers.

Let your artwork itself generate an ambient, immersive sound unlike anything you have heard. Great for setting mood or tone in a sound art exhibition space. And yet powerful enough to turn a 200 year old solid oak floor into a giant speaker. But which won't damage or crack more delicate surfaces.

Shire Hall Art Gallery Sound Installation System

Shire Hall in the UK dates from 1798, has a grade 2 star listed interior with an enormous concave ceiling. The age and listing meant no audio equipment could be attached to the walls or ceilings.

The trustees required a multi zone audio system for a constantly changing art gallery consisting of 24 zones or groups of high quality audio. With a wireless microphone also required for speeches and public address throughout the entire floor area.

"[Feonic] were sympathetic to the gallery environment and also to the creative and innovative aims of the gallery itself. And, above all, the sound quality is absolutely stunning and well beyond our expectations".

Kim Gould - Gallery & Exhibitions Development Officer, Shire Hall Art Gallery


Our sound transducers are easy to test in situ. You can test our speakers before installation by holding them against the surface to find the best sounding location. The perfect concealed speaker solution for artworks both inside and outside.
