About some animation of driver motion and actual sound wave propagation (rather than just monitoring Newton's law of gravitation and calling that sound particle mimicking ) (from ~30s in):

I Find this video very cool. Never have seen it. Thanks for the post!
If I may be so blunt to ask, but what's the big deal about this video? Isn't it just basically demonstrating what a speaker is meant to do? I know how planar magnetic technology works, and it's very cool...but seriously, particles being moved by a speaker diaphragm isn't anything new to people. If they had shown the magnetic field in action, then that might be something cool to watch. But yeah...particles moving from a speaker diaphragm.
this is like a frying pan gone haywire!
I think it's the background music used in this video. And I think it's kinda synced to it if you pay attention. lol.
It was NOT intended to.
It would be interesting to line up side by side:a) Dynamic voice coil driver, b) Planar Magnetic (Orthodynamic) drivers, and c) Electrostatic (non-moving) diaphragm,
and see the differences in driver movement.
I totally agree. Electrostatic > Orthodynamic > Dynamic
Are you saying that most Head-Fiers are truly abnormal people? ..... (although you may have a point here)
You really can't be serious! You must have a lower impression of any and all products that utilize advertising gimics to promote their product...how sad.
This is really what it's all about. It's not intended to be dissected and analyzed to death. It's interesting, well filmed and just plain old fun to watch.
I would be interested in seeing a video like this, either with or without the glass particles, where a sweep was used to show how the driver reacts to difference frequencies. Of course a clock displaying milliseconds would be nice, as would an indicator of what frequency is being played at any given time.
A laser imaging system could also be used either to view the particles or a flexible reflective coating placed onto the driver. This image could be viewed on a CCD camera array much like an old COHU 4800. See Particle Image Velocimetry:
Great idea for the video!
