You know those curly coiled ear-piece cables? (see link) So this
one's curls are as small as 2 mm wide. The cable is inside an
elastic cover. Stretches out to several times its original size.
An extra nice-to-have feature would be if the cable pulls back to
its original size only when given
a strong tug.
This, of course, is a half thought. I'm sure it's doable the only
question is in which of the many available methods.

This would be nice if it could be made to work. |
|
| |
One problem might be supercoiling: a very long helix will tend to form supercoils (ie, the axis of the helix will itself tend to form a helix), which would be tanglesome. |
|
| |
However, this problem could be overcome if you had two (or more) separate wires in the cable, coiled in opposite directions. That way, you'd have the same elasticity but the overall cable would tend to remain tangle-free, I think. |
|
| |
Another problem might be breakage of the conductors due to frequent bending/unbending, but this might not be the case. |
|
| |
No, "tinsel" braid superflexible cables, with high immunity to repetetive flexion, have been around for many decades. |
|
| |
I was thinking of something like this, the inspiration being
the annoying frequency* at which I break the conductor in
one of my earphones by snagging it on a door handle or
whatnot. My thinking was to make the conductor form a
gentle helix inside the insulation so that while the insulator
took the stress and strain, the conductor just uncoiled
slightly. |

Would it not be more effective, for so many reasons, to fit yourself with "breakaway" ears ? |

Duff link....thought I'd mention it..not like in me days, them
was links that lasted...just can't get the wood these days.. |

NB, are you quite sure of that "repetetive"...it's them
Ferengi keyboards, I tole him, yes I did, but did he listen..

Poor, poor Minnie Bannister... how she must have suffered. |

But you can get tablets for that now (allegedly). |
