The invention relates to an audible indicator (13, 113, 213, 313, 413, 513, 613) for use with a drug delivery device (1, 101, 201, 301, 401, 501, 601) comprising a bistable resilient force member (13.1, 113.1, 213.1, 313.1, 413.1, 513.1, 613.1) capable of residing in two states (S1, S2), - wherein in a biased state (S2), the resilient force member (13.1, 113.1, 213.1, 313.1, 413.1, 513.1, 613.1) is biased and stores energy, - wherein in a relaxed state (S1), the resilient force member (13.1, 113.1, 213.1, 313.1, 413.1, 513.1, 613.1) is relaxed, and - wherein the resilient force member(13.1, 113.1, 213.1, 313.1, 413.1, 513.1, 613.1) releases the stored energy when transitioning from the biased state (S2) into the relaxed state (S1), thereby generating an audible signal. |
