Well, I suppose it depends on how much of the lips vibrate.  I can
vary it from almost completely slack orbicularis oris (the lip-pursing
muscle) where the whole lip vibrates, to almost completely tense,
where only the most central portions of the lips move at all.

And that's just *pulmonic* bilabial trills.  Ejective and velar-egressive
b.t.s produce a whole different set of sounds.
