Coming Soon - Flat Speakers

A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear. Lightweight and inexpensive to manufacture, the speakers are slim and flexible: they could be concealed inside ceiling tiles or car interiors, or printed with a design and hung on the wall like a picture.

How about some specs on this... like some Freq response stuff...:confused:


Good point Warp. Just because it reproduces sound does not truly make it a "speaker". A wall can be turned into "speaker" with the stick on transducers. We shall see as the story gradually unfolds.

Supposedly, you can attach these to any surface & change it into a speaker/transducer. You could stretch a piece of heavy duty Reynolds Wrap in a frame, stick one of these things on, and presto – flat panel speaker.

Dayton Audio DAEX25 Sound Exciters turn virtually any solid object into a speaker by vibrating it at speeds of up to 20,000 cycles per second. The vibrations modulate the air, which is then decoded by the brain as sound. We've tested and placed Sound Exciters on nearly everything you can imagine; under a desk, in an overhead cabinet, behind picture frames, inside cans, behind paper plates, inside binders, cardboard, scraps of wood and even the box they came in! Test the limits of your imagination. Each stick on Sound Exciter is designed using patented nxt® transducer technology for a wide frequency response and great sensitivity. Built-in push terminals enable quick connection to the included pre-stripped speaker wire. Strong 3M adhesive pads affix to nearly any solid surface for secure, long-lasting playback. Package includes two Dayton Audio Sound Exciters and two pairs of 5 ft. speaker wire. Specifications: • Power handling: 6W RMS • Impedance: 8 ohms • VCdia: 1" • Dimensions: 3-1/2" dia. x 3/4".
• Turn any solid surface into a great sounding speaker system
• Create a completely hidden surround sound system
• 3M adhesive pads for secure and fast placement
• Wideband frequency response (dependent on attached material)

It would be cool to rig something up & plug it into the Emotiva XPA-2 just to watch it catch fire.

I find great irony in this. Does anyone else.:)
