behold!
this is the rumble in a ps3 controller. it spins that heavy metal thing that’s off balance at different speeds to create the vibration.
haptic motors of modern consoles are much more complex but they follow similar mechanics
They have a tiny motor that spins an unbalanced disc. The heavy part of the disc wants to go to the outside, but has no counter weight, and tugs on your phone or toy ever so slightly.
An electric motor turns a shaft with an off-center weight. This weight shifts the system around and round.
Put a couple of quarters in an empty pill bottle. Now shake it back and forth a little. The mass of the coins moving around will “effectively shake” the bottle. So basically to cause shaking you need to move mass.
Have a standard motor with a mass off to the side of the shaft and turn it on. Get a shake. Have a mass on the end of a solenoid and turn it on and off. Get a shake. Raise and drop a mass, get a shake. Basically any way you can move a mass in a way that isn’t smooth you will get a shake.
