Speakers that produce good quality of sound will no longer be big and clumsy. Perhaps, you wouldn’t believe it, as in your mind, a sub-woofer is normally housed in a large and ugly black box. But Warwick Audio Technologies have designed these super thin speakers, which are completely flat like a piece of paper and they are flexible that can be bended to suit various needs for interior designs. And the most important is they’re claimed capable of producing good sound.
These flat, flexible loudspeakers can be printed and cut into various shapes to suit the need of the design of a house or the interior of a car. The super thinness and flexibility should allow it to stick like wallpaper or to be concealed in a vehicle.
Warwick Audio Technologies, a company that spun off from University of Warwick, claims that these speakers are able to produce very good sounds, despite the ultra thinness. Believe it or not, these ultra thin speakers measure only a quarter of a millimeter in thickness. Warwick has provided some information to support their claims of how these flat, flexible loudspeakers can produce accurate and powerful sound. The information provided related to the materials that make up these speakers and how sound wave travels, as follows:
The speaker material is a laminate composed of sandwiched insulators and conductors, which with the addition of the electrical audio signal, vibrates and produces a planar wave with high directivity and precise imaging. The wave spreads evenly across a listening room or audience and doesn’t drop off sharply based on distance. Warwick has also expounded upon the fact that FFLs are inexpensive to manufacture, meaning that they could be a viable option for basic home and car audio.
Warwick describes the speakers as efficient and low power, driven by voltage and dissipating little current into heat. Distortion is also said to be minimal. This statement offers a very promising glimpse: “By significantly improving the electrical to audio efficiency, we have broken the conventional link between the power rating and the loudness of a speaker. The loudness of cone speakers is often linked to the electrical power consumption. This is not a relevant relationship for the FFL.” Perhaps, in addition to space, you can save a little money on the amplifier.
Everything sounds perfect. Hopefully, they are truly inexpensive so they could take over home audio soon.
