Jonas B, vibrations in any camera system can be caused by any component of such system like the camera’s shutter, parts of strap, lens adapter, lens filter, attached hood, camera plate, tripod head, tripod, tripod’s elements like spikes, fasteners, and on and on. Vibrations generated by any of these elements can be absorbed, dissipated, stored and released back into the system; all affecting final images.
Pointing precisely to a specific element as single source of vibrations causing image blur would require tests performed in isolation and well controlled environment, I would guess.

Except none of those other elements you listed can generate vibrations without external perturbation, so while a given implementation of those elements may be improved to dampen vibration they can never technically be the "source" of it. So experiments to isolate the source of the vibration will always lead you back to something inside the camera. This may seem like a pedantic distinction but when you consider the complexity of modeling resonance and worse, the time and expense that photographers would have to endure putting together disparate, prosumer-grade elements to avoid its complex interactions, the most reliable solution is always to prevent the source of the vibration in the first case. Which is why camera makers go through so much trouble to dampen movable elements within their cameras and also why they offer additional options to avoid it (mirror lockup, timer/remote release, electronic shutter curtains, aperture rings).
