Why Do My Night Vision Binoculars Whine?

I bought a pair of 1st generation Seben binoculars and am curious as to what causes the whine when they are active. I understand the principle behind how they work, but what causes the whine?

if you think about it the light particles are moving at 7000 times the speed of light, bouncing off the various lenses in the binoculars.
You keep staring at them! Just kidding.
Probably not working right, they should be quiet.
temperature changes within the tightly sealed case, contact the manufacturer, you have a critical recall on that. Seem that they explode when left in heat too long.

It's been scientifically proven that guys find girls with their eyes a shade darker than the rest of their face more attractive. So eyeshadow is a must! :]
