Elastic lips sustain oscillation only when energy is continuously input
Evidence
The lips of a brass player (or vocal folds of someone who is singing or speaking) are elastic; that means that if they are displaced from their rest position, they will oscillate around it due to the restoring force that acts on each lip (or vocal fold) to move it back to its rest or equilibrium position. … Provided there is some energy input to the system, in this case causing the lips (or vocal folds) to move toward each other, the movement can be started and, once started, continue as a sustained oscillation. — David M.
