The ring is caused by the tone ring vibrating at a different frequency than the main bell flare. This happens because these are two different pieces of metal (the tone ring being nickel or nickel-plated), and over time the solder weakens. This may manifest itself in a buzzing sound, or a vibration, thus the ring. All sound is produced by vibration, and on an instrument when something is loose this can occur.

Take a tuning fork into account. When you tap on your hand and hold it up to your ear, what you are hearing is viration of the metal caused by its structural design. Brass instruments need to be solid due to the vibration of sound that passes through them. When a brace is weakened or in your case a tone ring comes loose, it can manifest itself in odd ways, and this can produce ringing. Take the backs of your fingernails and light tap the bell, you will hear ringing. The ringing you are hearing is caused by the frequency of the notes (or one of their harmonics) and how it is interacting with the brass on the horn.
