FIELD: transport.
SUBSTANCE: invention relates to info systems and converters of mechanical effects into optical signals. Proposed annunciator comprises interconnected converter of mechanical power into electric power and converter of electric power into optical power. Said converter of mechanical power into electric power is composed of encased piezoelectric element with damping gaskets. Elastic element (helve) has one end clamped to the case and includes hammer on its free end aligned with said piezoelectric element. Bicycle wheel rim is equipped with pusher (hook) to allow mechanical contact with elastic element free end in wheel rotation.
EFFECT: higher efficiency and reliability, expanded performances, longer life.
