from iFixit's teardown

On the inside, this vibration motor seems fairly standard. It's essentially a voicecoil installed in a moving mass assembly, flanked by a pair of powerful magnets.

However, it's interesting that this LRA seems to vibrate along its short axis, while many haptic feedback motors that we've seen vibrate along their long axis.
