As these work?

This article show the scientific basis of ribbon microphones. For now we can show this video, where the sensitivity and the degree of adaptation to displacement by wave fronts in the ribbon mic is observed. In this case, the tape is folded into a semi piston shape. Has some folds which make suspension the other and rigidify the tape at the center.

 

This form of folding tape, characteristics of Beyer microphones, among others. Currently the trend of manufacturers is the ribbon with transverse folds along its length. Have slightly less sensitivity, but the sound at high pressures has less distortion.
