So, I salvaged an old USB Joystick that stopped working on my PC, but I'm not sure of what this component in the attached pictures is. As you can see, it is not very big, and it has SG written on it. I think it might be a speaker or a vibration motor, but I'm not sure.
Do any of you know what this component is, or how to test its function?

There are two solder fields, and if you look closely you can see that one is connected with tiny tracks to the outside shell. That's ground. Use a ~6k8 resistor from the other field to power (3-9volt).
Tap the sound from the same field with a dc blocking capacitor.
You need to add a preamp if you want a usefull signal.
Many electret examples on google images.
