My recollection of information from Lani Herrmann is that the mechanism for
buzzing is very interesting. Instead of the usual (for stringed
instruments) wide, flat bridge, the bridge for the trompette, the buzzing
string, is sort of like a koto bridge, an upside-down "Y", and one leg is
off the soundboard by a very small distance, and the bridge foot buzzes
against against the soundboard when driven by the string. Apparently there
is a threshold level of speed of the wheel below which no buzzing happens,
so that speeding up over that threshold and backing down below in a
rhythmic pattern results in the rhythmic surge of buzz.
Sounds harder than regulators to me.
