Roll to Roll Headphones focuses on a type of production increasingly used with the miniaturisation of technology: the production process that involves thin layers, also known as the ‘roll to roll’ process. Through an object – such as a pair of headphones in this case – the designer challenges traditional ways of designing and producing the object. The ‘roll to roll’ process simplifies the composition of an electronic device and makes the composition legible again through its form. Through several models, the designer also explores how these techniques influence the vocabulary of the object that is stratified and made up of superimposed layers. In addition to this exploration, the advantages and benefits of the ‘roll to roll’ production technique is questioned. Techniques and equipment used are mainly printed electronic circuits, hot welding on plastic, hot embossing and laser cutting. Speakers are designed based on the vibration of a piezoelectric cell, which vibrates on a plastic surface. This system produces a sound comparable to conventional systems but it is only 1-millimetre thick. This type of speaker does not contain neodymium like conventional speakers – an interesting point in the thin layer production process. Working with simplified elements, efficient materials and processes – where technology is often the material itself, rather than an assembly of material – this simplicity is visibly manifested in the design and composition. By reducing the number of parts and assembly usually required for the production of headphones, it also reduces mechanical parts subject to wear and improves cohesion and durability. With the production method simplified, these headphones can be produced with one single production line without any injection moulding. It’s a physical reflection of the economy and flexibility of processes, and the materials and means in the production of electronic devices.
