At one point there were spring based audio delay devices use for

solutions when dram started showing up.
They weren't spring based, just a loose coil of wire.
Take a look at https://en.wikipedia.org/wiki/Reverberation under
Spring reverberators.
These are the ones I knew of but there may have been some other
devices based on other operating principles.
I remember those reverb springs, from back when I was a kid. The delay
lines I'm referring to look like the one pictured in this link.

Ah now that is interesting.
Sending bits down the line as sound waves is an interesting concept.
You would need to feed them from the output back into the input along
with some timing signals to use it for memory.
I got into computers when core memory was on its way out so I never got
to see any systems built using this kind of technology.
cheap mass produced bits in silicon has made a whole bunch of really
interesting technologies go away.
