The magnet is around an order of magnitude more powerful on the coil side versus the back, so must be Eddie/Maxwell magic mathsticism of some wizard variety. Are these style drivers typically rare earth magnets? The sticking power feels like a rare earth magnet, but I don’t know that factually is the case. Perhaps the flux is unintuitive when guided well.
Is the port shape intended to increase the Reynolds coefficient… (Is that even a valid question at this limited displacement volume? Like, I don’t even know how, or if, this falls between laminar and turbulent regimes, or if such a system should be modeled more like a spring and damper or something like that.) Do you think the little square volume in the lower left is intentional or a byproduct? Does this port design have a niche name specific to the zigzag?
Bass port, they use the geometry of the port to fill in lower sounds with constructive and destructive interference from the echos along the path, it’ll give it a more full sound from a tiny cheap speaker.
It’s called a labyrinth. It helps certain frequencies. It was added to compensate/enhance a frequency, probably bass.

Indeed. It is probably a Halbach Array: https://en.wikipedia.org/wiki/Halbach_array
That port has nothing to do with Ryan Reynolds.
I think Ryan would be disappointed to hear this.
All that black plastic is there to make it look like your $500 TV came with better sound than a $0.50 driver.
Magnet may be covered if it was a CRT TV, stop magnet affecting the picture??
I think that one was from a small plasma ages ago. I’m pretty certain it is for directing the magnetic flux because of how strong it is in the one direction. Like from the back it sticks like a low quality ceramic magnet that can barely hold its own weight up. From the other side, it requires a very firm grip to remove from typical sheet steel appliances and furniture.
