Traduction de l’étape 21
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.
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.
