Coralie Gourguechon is a french designer. Her interest in electronic and digital devices started from a realisation that she wasn’t able to repair digital devices. Through physical and semantical dissections, she tried to understand and simplify those objects. This anatomical chart of a speaker presents the hidden operating system in a graphical way, it is an educationnal tool that should be intelligible and attractive. Here, the anatomical chart looks like a skinned speaker, with components left visible, and signs that visually represent their technical role. The speaker cone is detached from the sheet, and spreads out to form a mechanical amplification of the sound system. When flat, the speaker is turned off, as the folding close the circuit, creating a switch system mecanically.
