That's what the schematic shows, or more precisely it shows a relay coil, I can't
find the actual part description.
Curiously enough, the earlier VT05 does have a proper beeper, with an 800 Hz oscillator
feeding a speaker. And the VT61/t, which is a block editing terminal for Typeset-11 in a
VT52 case, also has a speaker for the key click (and I assume for the bell/beep though I
didn't look that far). Then again, it's not clear whether the VT61/t has anything
in common with the VT52 other than its case and perhaps the CRT and some of the power
supplies. I remember a collection of rather hairy looking circuit boards, the final last
gasp of single-sided PCB technology with hundreds of jumper wires on the component side...

Anyone know why DEC chose to use the grind-noise? it was a singularly
unpleasant sound, it had the effect of not wanting to trigger it.
From what I remember it's actually a little relay on the main circuit
board. A single pulse for the key click and a buzz for the 'bell'
