Meanwhile, the PET layers surrounding the domes add the requisite structural integrity for the material to be able to bend and be attached to surfaces without hampering sound reproduction.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Manufacturers can then tweak the acoustic properties of the material by resizing and rearranging the domes, leading to all sorts of interesting applications. The domes could be arranged to focus sound to specific locations in a room, to be used in ultrasound imaging, or even to \u201cprovide a novel method of stirring chemicals.\u201d Sure, why not.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Circling back to this article\u2019s lede, the weight and flexibility of the material also mean it could be used like wallpaper. Aside from the immersive implications of such a design, the ability to cover large areas and precisely shape sound means you could theoretically turn your walls into noise-canceling surfaces, functioning much like noise-canceling headphones to prevent outside noises from filtering into your home.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This idea works with regular speakers too, but limitations in positioning make it essentially impossible in any practical sense.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">But enough talking \u2014 take a listen for yourself.<\/span><\/p>\n<p><iframe loading=\"lazy\" title=\"A paper-thin loudspeaker plays \" we=\"\" are=\"\" the=\"\" champions=\"\" by=\"\" queen=\"\" width=\"500\" height=\"281\" srcdoc=\"&lt;style&gt;*{padding:0;margin:0;overflow:hidden}html,body{background:#000;height:100%}img{position:absolute;top:0;left:0;width:100%;height:100%;object-fit:cover;transition:opacity .1s cubic-bezier(0.4,0,1,1)}a:hover img+img{opacity:1!important}&lt;\/style&gt;&lt;a href=\" https:=\"\" src=\"https:\/\/img.youtube.com\/vi\/pABxdxTuAY8\/hqdefault.jpg\" style=\"top: 50%;left:50%;width:68px;height:48px;transform:translate3d(-50%,-50%,0)\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"><\/iframe><\/p>\n<p><span style=\"font-weight: 400;\">Okay, so that doesn\u2019t sound great. But I mean, when have you heard anything the size of a Post-It note make a sound at all?<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The fact that it\u2019s able to produce audible sound in such a form factor at all is pretty remarkable, especially given the design seems rather efficient. A square meter of speaker material uses about a tenth (100 milliwatts) of the electricity as an \u201caverage home speaker\u201d (1 watt) for similar decibel output.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Granted, most home speakers don\u2019t have a square meter\u2019s worth of radiating surfaces \u2013 all else being equal, the larger the radiating surface, the more efficient the speaker \u2013 but such speakers would be so large as to be impractical. The compelling part of the PVDF speakers is that you could line your home \u2014 or the interiors of cars and performance venues \u2014 with the material without occupying virtually any space.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If the <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a> pans out in commercial use, I can see it being a godsend for mobile devices. It is fundamentally difficult to fit large traditional drivers onto laptops and phones. The drivers and their associated magnets simply take up too much space (not to mention the added weight). The PVDF speakers, on the other hand, could occupy the entire surface area of your phone or laptop without adding much to the overall volume or power demands.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The researchers will have a lot to prove before these PVDF speakers hit the market. For one, they\u2019ll likely struggle to reproduce bass in large quantities, and it remains to be seen how cost-efficient the design will become, compared to tried-and-trusted driver designs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Still, I think it\u2019s one of the coolest innovations in the world of speakers for some time. I\u2019d like to imagine a world where speakers can be easily and invisibly integrated into our homes, rather than trying to find the perfect location to stick massive wooden boxes. Here\u2019s hoping I\u2019ll be able to get some wallpaper speakers at Home Depot in the years to come.<\/span>\n                        <\/div>\n<p><script async src=\"\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
