The thing that is patentable isn't "a vibration". It's the exact, specific means through which you produce that vibration.
We've gone from completely dumb eccentric rotating mass vibration to trackpads that you'd swear are actually physically clicking, or the Ice Cubes demo in in Nintendo's 1-2-Switch[0], both of which use linear resonant actuators. Those actuators are themselves a complex enough piece of technology to warrant a patent, and the techniques to simulate the feel or real physical objects using those actuators are pretty damn non-trivial as well.
As a general rule, I find that the patent system is problematic but, within the scope of the system as it exists today, these are perfectly reasonable things to patent.
It's literally a voice coil with a mass on it. Literally anyone who has ever played with a solenoid, and hooked it up to a speaker, has made one. I did it when I was a kid, decades ago, and watched it vibrate on the table and in my hand. When I tried the first haptic thing I knew exactly how they did it. It's so incredibly obvious I don't understand how it's even patentable, with all the prior "make thing vibrate with electromagnet" work.
It's not really "high tech", it's just tuned well, with some high power for the size.
> trackpads that you'd swear are actually physically clicking
Like my Mac's trackpad ? Can someone ELI5 how it works ? It's gotta be magic-adjacent cos when the machine locks up, the trackpad is deader than a doornail.
It's the same technique of the "3D touch" the iPhone 6S had, though that was discontinued. Capacitive sensors measure microscopic changes in the glass, as it slightly flexes when you press it. Then a haptic motor does a little kick to simulate the feel of it being pressed down.
They've been doing this since 2015 or so. Prior Macs didn't click on the top 1/4 of the trackpad, because there was basically a "hinge" there and the glass would actually press on a physical button.
So there's a big big matrix of tiny tiny motors under the trackpad ?

Fun fact, the other thing that can cause this is a Bluetooth mouse in a backpack that is being clicked continuously. Confused me to no end for fifteen minutes.
Have noticed exactly this behavior as well, it's one of the better indicators actually the system ain't coming back.
