  • Teardown Update: Just to make sure we were getting our fill of secret sauce, we popped the top off the haptic feedback motor, a linear resonant actuator (LRA) that powers Switch's HD Rumble.

  • These LRAs look very similar to the ones we pulled out of the Oculus Touch controllers, HTC Vive, and the Steam Controller.

  • We took a second to pop open a Oculus Touch haptic motor and it seems to be internally identical to this one.

  • 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.
