That's an electrolytic capacitor charging. The noise is called coil whine, and the reason it goes up in pitch is due to a material property called magnetostriction.
It's most likely a photoflash capacitor, but the sound effect tends to get used in media for things like night vision goggles, defibrillators, tasers, or laser pointers.
Sounds more like generic video game night vision goggles
I think it's a capacitor charging or discharging, I can't remember which.
