What is this movable diaphragm in the bottom of the speaker for?

Taking this speaker apart to put in a Fanny pack and I was curious what the diaphragm in the bottom does for the speaker.

It’s a “passive radiator”: https://en.wikipedia.org/wiki/Passive_ra...)

I assume this was chosen over a ported design because it doesn’t require a hole where water could get in. :)
