As an alternative to round and flat transducers, cord speakers are installed in party buses, closets, and just hanging there in your house.
Each cord is essentially a stringed instrument that plays itself.
Portable versions could be made into concave enclosures to direct the sound.
Built into your party bus, for complementary sound...

Welcome to the bakery and thank you for having the
guts to post an idea. I'm not able to garner up the guts
lately, so good for you. Not sure about the actual idea
though. Gotta think about it. Have to research what
you suggest. |
|

Could be cool combined with strobe lighting and some of those EHT-
discharge tweeters. [+] |
|
| |
The idea sounds cool, but I doubt it would work
very well. Think of a guitar string. You can pluck
it hard and see it vibrating 1/8th inch, but if it
weren't for the body of the guitar, it is barely
audible. A vibrating string doesn't actually move
much air. |
|
| |
Now if you made a string or cord that could change
its diameter very rapidly rather than vibrate, then
this could work, but I'm not aware of any way to
do that. |
|
| |
Cordtex can increase its diameter very rapidly, but the process isn't
reversible ... |
|
| |
As was said, a string by itself doesn't move much air. The string has
to vibrate something flat, usually (the term is "impedance matching").
You might be able to use a ribbon, instead of a string. |
|
| |
^Ribbon speakers are rather deep-fried. |

Lord Kelvin (he of the temperature unit) invented
two forms of amplifier. One was the Kelvin Water
Amplifier. |
|
| |
The other was the Gunpowder Amplifier (though,
technically, it wasn't an amplifier), consisting of a
line of gunpowder whose thickness varied,
waveformwise. He successfully reproduced the
first four notes of Beethoven's Fifth. |
|
| |
The string needs the violin in order to make a
significant amount of noise. |

Well, there's your resonant chamber. Tension the strings between the roof and floor of the party bus or closet. Drive them electromagnetically. Bam, mobile or bedroom string orchestra. |
|
| |
Now, where to order a nice mahogany party closet... |
|
| |
//tension the strings between the roof and floor// but
then they wouldn't be "just hanging there". My bone
remains until I see a clear way for loosely hanging
wires to vibrate with sufficient energy to make a
decent speaker. |
