Sonoflex: Embroidered Speakers Without Permanent Magnets

“…When implementing light-weight speakers many researchers focus on "paper-based" solutions Ishiguro et al presented Uminari, an interactive electrostatic loudspeaker [19], which was also combined with 3D printed objects [20]. Similarly, Kato et al presented OrigamiSpeaker, a hand-crafted paper electrostatic speaker, which is low-cost and can easily be fabricated with inkjet-printers [23].…”

“…In contrast to electrostatic speakers [19,20,21,22,45], dynamic speakers as in our approach do not require high-voltages and are therefore more safe to touch. Similarly to the vibrotactile widgets (cf.…”
