  • Publication number: 20210275750
    Abstract: The present disclosure relates to an audible indicator for use with a drug delivery device comprising a resilient force member configured to reside in one of a relaxed state and a biased state. The audible indicator comprises a retainer adapted to maintain the resilient force member in the biased state. The resilient force member releases stored energy to impact a surface to generate an audible signal when the resilient force member changes from the biased state into the relaxed state.
