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.
  • 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.

拆解更新:正好来看看我们拿到的秘密武器,我们掀开了触觉反馈马达的盖子,它其实是一个 线性共振螺线管 (LRA) ,用来支持Switch的高精度震动。

这个线性共振螺线管看起来和我们之前从Oculus触控器, HTC Vive, 以及Steam 控制器上拆下来的很像。

我们又拆开了Oculus Touch的触觉马达,它的内部和这个一模一样。

在它的内部,这个震动马达十分标准。 它本质是一个安装在变质组件上的音圈,位于一对强力磁铁旁。

然而,有趣的是这个LRA似乎是沿着其短轴震动, 而大多数触觉反馈马达是沿着它们的长轴震动。
