Removing the speaker reveals the 12-series-standard (and festive) orange ingress-prevention gasket.

Considering the already shrunken Taptic Engines, we're surprised to see an even shrimpier one in this mini.

This tiny Taptic Engine measures 15.14 mm x 10.9 mm x 3.44 mm—25% smaller than the motor in the 12 and 12 Pro.

Taking advantage of that "extra" space: a beefier cable and socket.

We had suggested there might have been enough space for a headphone jack in the 12 and 12 Pro—no such luck for the mini. The Taptic Engine and speaker fit much more snugly here.
