Does anyone know of a loudspeaker that works according to this principle:
A voice coil works against a cylindrical accordion. The 'accordion' is of course fixed at the top. In principle an omnidirectional AMT.
The cylinder below is a voice coil.

There is a "classic" voice coil below.How do you make accordion constrict like amt
There will be a difficulty to get the accordion flexible enough to allow "breathing" but still stiff enough to push air. But maybe it's just a question of geometry?
No, but I think this is close:

There's no pleating in MBL's radialstrahler, but the basic drive principle is the same.

Every Radialstrahler chassis consists of individual petal-like segments, known as lamellae, which are arranged in a circle around a central axis, resulting in an elongated spherical shape. Each individual lamella is permanently fixed at its upper end and attached to a voice coil at the lower end, moving freely in and out of the magnetized gap.
