Natural vibrations in the springs cause phase shift and delay of the signal, which is picked up at the other end. Then you mix it with the "dry" audio signal to give an echo or reverb effect.

Nice transformer! It must be great being able to make your own!
Ah, spring-reverb is called "Hallfeder" here. Thanks for explaining.
