‘roll to roll’ production processes are often applied to the miniaturization of technologies, in techniques like printed electronic circuits, hot welding, embossing or laser cutting — in effect, simplifying the composition of an electronic device. presented at wanted design for the ENSCI — diplorama+ exhibition during new york design week 2015, maxime loiseau explored this type of manufacturing method to smarten and streamline a ubiquitous technology: headphones.

‘through an object, I challenge this new way of designing and producing an object’, loiseau describes. ‘I question the advantages and benefits of ‘roll to roll’ production techniques, and also explore how those techniques influences the formal vocabulary of the object, made of thin strata and superposed layers.’

in terms of production and materials, everything has been simplified: electronic circuits are printed instead of using wires, plastics are welded instead of using junction parts, and shape is given through embossing rather than expensive injection molds. aesthetically, as the process is similar to that of offset printing system, then object conception become similar to a graphic composition and each technical component becomes legible again — for example, you can see the circuit feeding the piezoelectric cell.

the speaker functions based on the vibration of a piezoelectric cell, where electricity results from pressure. through the piezoelectricity that occurs on the plastic surface, the system produces a sound comparable to a conventional unit, but is only 1mm thick.

the ‘roll to roll’ design adopts simplified elements and efficient processes, where technology is the material itself, rather than an assemblage of various matter. the headphones can be made with one single production line without injection molding — a reflection on the economy of processes, materials and means in electronic devices production. each earpiece can be composed of 8 simple parts, whereas a standard headphone can use up to 50 pieces.

‘the project doesn’t change the way we will use headphones’, loiseau says. ‘the purpose here is to offer a reflection about producing electronic devices in a smarter way. the more materials are advanced, the more they are paradoxically easy to work. through one production process, we can then using less process, less material, energy and pieces. at the same time, I tried to use the possibilities of the process to create an aesthetic result from it, a more fair product, with no superfluous parts.’
