Flat Panel Speakers - Turn any Surface into a Speaker

The best flat speaker has to be no speaker at all

Feonic have a 15 year history developing surface speakers. We've pioneered new markets along the way. Such as Whispering Window® for retail, and the often imitated Soundbug®. Our technology isn't suited to cheap gadgets you attach to cereal boxes. This is a professional audio technology suitable for an endless range of home and business sound applications.

  • Sound enable: walls, floors, ceilings. Desks, tables, furniture. Wood, drywall, plasterboard, sheet metal. Glass, plastic, plexiglass.
  • Easy to fit using simple DIY tools: screws or sticky pads for glass.
  • Mount around the home for sound zones in every room including halls and bathrooms.
  • Play the sound of the ocean, oars splashing, timbers creaking as in the maritime gallery example below.
  • Play a poem or music from an artwork.
  • Enable museum visitors to hear a historic musical instrument intimately; direct from the glass of the display case.
  • Nothing visible - just sound.


Picture Frame Speakers - Turn your favourite artwork into a flat speaker

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

Picture frame speakers project by Adriana Paice. Intimate sound played just for the viewer.

An alternative approach to loudspeakers is to convert an artwork into a flat speaker. The picture frame hides the audio technology: the surface generates the sound. Creating an exciting immersive audio experience without speaker boxes or grilles.

We should show you an image of one of our invisible speaker solutions here. But there is nothing to see. Take a look at your wall, ceiling or floor...
that's what your flat panel speakers will look like

You've already decided you don't want or can't use a traditional box loudspeaker. Why settle for a traditional flat panel speaker? Just use everyday surfaces for the thinnest speakers possible.

Invisible Speakers for Immersive Museum Installations

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

In this case the devices allow us to invisibly transform a 10 meter long wooden walkway into a multichannel speaker array.
The walkway runs alongside the boat and sound emanates from the entire surface of its structure. Listeners are able to associate sound with the exhibit directly and intuitively. More so than if the sound were to come from an obvious loudspeaker.

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

Take a look at more of our many case studies. You'll find examples for invisible speakers around the home; advertising from store windows; sound art installations including picture speakers and more.

We can help you turn any surface into a speaker - it just has to be resonant. That is, makes a nice sound when tapped. A brick or lump of concrete? No. A wall, wooden floor, glass panel, ceiling, sheet metal? Yes.

Any Surface Speaker Drives

Flat Speakers are created when our surface transducer applies micro vibrations to a resonant panel.

This approach enables you to hide the small transducer near the edge of a panel. Mount near the bottom of a wall where it can be hidden by furniture or on the reverse side of a surface making it completely invisible. Besides great quality audio you also get a more even sound distribution. The entire panel emits the sound; preventing "too loud" hotspots.

Extreme Speaker Solutions

The biggest drive in our range has the same footprint as a smartphone and is a few inches high. The smallest is a little bigger than a matchbox. But a few drives can distribute sound over a huge area...

Flat Panel Speaker for PA System
Extreme Speaker Solutions. In this case we developed an echo and reverberation free PA speaker for Warehouse, Factory and Commercial Premises.
Sound enable surfaces of any size. From artworks, desks, museum display cases up to massive store windows and oak wooden floors in galleries.

Loudspeakers: always at or near eye level: always in line of sight. Why?

Whether hidden or fully invisible our drives avoid loudspeaker clutter: boxes, wires, brackets.

Always at or near eye level: always in line of sight.
And this visible distraction for a technology for the ears not the eyes.

A loudspeaker embedded in a ceiling, wall or display case results in an untidy grille. Resulting in poor design outcomes and can attract dirt. Most typical flat panel speakers are thin but still boxes only slightly less obvious than their boxy cousins.

Choose Feonic to avoid visible clutter and an expensive and messy installation. Create flat wireless speakers as wires are easy to hide.

Both sides emit a high quality dispersed sound field for an immersive surround sound experience. No surface damage. 50Hz up to ultrasonic frequencies of 22KHz. Perfect for music, voice messages or special effects like anti-noise sound masking.

Where are our Flat Panel Speakers used?

Event space speaker system
Boost social sharing with innovative speaker technology


Use our vibration speaker technology behind, or on walls, as ceiling speakers and even under floor speakers. Thin speakers for picture frames or completely flat where the surface is the speaker.


No matter the application, the crucial factor is that the vibration speaker drive is out of sight, only the original surface is visible. Which we think makes the Feonic solution the ultimate Flat Panel Speaker.
