A modern way of life had society developing the habit of taking with them some sort of auditory entertainment wherever they go. According to https://www.tldevtech.com this can be in the form of earphones when in public and portable speakers when alone. But, what if, you’ve got yourself a speaker that can help you catch your next ride?
A Modern Take on Sound Generation
Engineers from the University of Warwick came up with something that can amplify and improve the sound quality of public announcements in passenger terminals, and it’s no thicker than 0.25mm. What it lacks in girth will be thoroughly compensated by how much it can improve the quality of life for communities in the future.
This invention was pioneered by Warwick Audio Technologies, a spin-out company from the aforementioned university and was initially named the “Flat Flexible Loudspeaker” or the FFL. It was conceptualized to be a lightweight piece of material that can be hung on a wall like a painting but will be able to generate directional sound waves that are planar. This makes it ideal for public spaces as it can project crisper and clearer sounds further than a typical speaker.
Manufacturing of this loudspeaker will also be inexpensive and display can be innovative, with these speakers to be concealed as part of the cladding or tiles in interior fit-outs for vehicles or the building.
An Efficient Addition to Everyday Life
Steve Couchman, the CEO of the pioneering company, believes this idea may cause a domino effect that could replace the conventional speakers used in our daily lives. When applied on PA systems, Couchman also claims that the sound quality of the FFLs will not deteriorate as the volume increases.
The plan was to have the FFL incorporated into public address systems, with the purpose to relay information effectively and efficiently. Such technology can also be integrated into our smartphones, laptops, and even cars, whose hardware had been turning micro over the years. If such an initiative pushes through to the market, this jeopardizes the sales for portable speakers, if not make conventional speakers altogether obsolete.
How Does It Work?
Warwick Audio Technology’s design for the FFLs had evolved into the carefully modified thin flexible laminate, both with conduction and insulation properties that will produce sound through vibrations caused by electrical signals.
Conventional speakers share a similar basic principle for sound generation, but the FFL will work akin to a piston resonator. Here, the diaphragm of which forms an area source as it radiates in phase. Now, the waves emitted through vibrations on the surface become phase coherent. Thus, the plane waves produced will have very accurate imaging and high directivity.
FFLs Are Well on Their Way
Early attempts at the project had Dr. Duncan Billson and Professor David Hutchins, both are as well from Warwick, generating sound using tin foil and baking paper. They have gone a long way since then.
The pioneers are now eyeing the concept as a commercial success and are currently in the business of looking for partners on the venture. Although they remain open to fresh ideas and design approaches, Warwick Audio Technologies plans to push through with their product launching soon.
