Anatomical board of a speaker

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, and the position of the cone is also an indicator of operation. When flat, the speaker is turned off, as the folding close the circuit, creating a switch system mechanically.
