SOFT SPEAKERS

I designed a set of custom fabric actuators that can be used as audio speakers and vibro-haptic feedback using arithmetic spirals. Digitally-embroidered with silver-plated threads, I made these tactile, malleable and aesthetic e-textile designs to be part of wearables, soft furnishing and fabric objects. With parametric design in additive and constructive methods, I prototyped 3 wearables, a piece of furniture and a soft toy. This can help empower maker-users expand the design space and support inclusive design.

“While at work, I find it uncomfortable to use headphones on top of my scarf and even more challenging to use earpieces as it gets tangled with my covered hair”. Supporting diversity and inclusive design, Soft Speakers inspired a technically simple DIY solution to embed ‘sound in a scarf’: “I used to think that no headphone designer ever considered a user with a headcovering. Now with this 2in1 scarf, I feel empowered.” We digitally embroidered two speakers to standout as part of the fabric pattern, to “look like an embellishment on the fabric”.

Judy couldn’t use earphones that fit her ear size and with 6 months of Canadian winter, she had a need to combine her snow hat with headphones explaining: “you can’t really walk around in headphones in winter, and you can’t wear it on top of your tuque. Some people use earphones but I don’t find them comfortable”. She sketched her design with a colour palette inspired from her winter suit. We used a matching wool yarn to add some embellishment (in the form of: couched seams, 2 dangling braids, and a pompom on top) for the aesthetic desirability of the hat. Finally, we added an invisible zipper with a matching colour to allow easy access to the sewn circuit. When Judy wore it during her outdoor walks, she used it to listen to her favourite sound track and navigate Google-Maps. She was happy and excited to be able to clearly hear the directions, while staying warm and without headphones, just by plugging the audio jack in her hat’s braided chin tie: “I love how it’s easy to use and easy to access the electronics inside”. Mary elaborated: “This is way better than headphones, because you can walk with it without anyone noticing that you’re listening to anything. . . It’s more comfortable because it’s soft and fabric so it is much better because it warms my ears, covers my head and a speaker. . . [but] nobody else can hear, then I can have something [private] playing and no one else would say oh what’s that?”
