Episode 1: Designing the Lithium Speaker — Circular Design Meets Digital Product Passports

Welcome to Episode 1 of the Circular Design Series — “Designing the Lithium Speaker in Autodesk Fusion.”

This marks the beginning of a new video series from Infinite Acoustics & Lostboyslab, in collaboration with whatt.io, exploring how Digital Product Passports (DPPs), AI, and circular design principles are redefining sustainable manufacturing — from the first sketch to the final product.

In this episode, we take you inside the design process of the Lithium ONE and Lithium TWO speakers — from concept to CAD — using Autodesk Fusion.
Every design choice, from materials to modularity, is made with circularity in mind, ensuring that each speaker is traceable, repairable, and designed for a long life.

In this episode:

• Early design concepts and 3D modeling in Fusion

• Modular speaker housing and integration of NFC tags

• Planning for disassembly, repair, and upgrade paths

• How whatt.io’s Digital Product Passport is embedded from day one

Each Lithium speaker carries an NFC tag linked to the whatt.io platform, providing instant access to verified data on materials, CO₂ footprint, and spare parts — turning the product into a living digital identity.

This project is also part of the broader European and Swedish innovation landscape, connected to the EU’s CIRPASS-2 initiative and Vinnova’s MCSR project, where whatt.io and Infinite Acoustics contribute to shaping the future standards for DPP implementation, traceability, and circular production frameworks.

“Designing for circularity isn’t an afterthought — it starts on the CAD screen,” says Stefan Larsson, Group CEO of whatt.io. “By merging design intelligence with digital identity, we’re proving how the next generation of products will be both physical and data-driven.”
