The invention relates to an audible indicator (13, 113, 213, 313, 413, 513, 613) in combination with a drug delivery device (1, 101, 201, 301, 401, 501, 601) comprising a resilient force member (13.1, 113.1, 213.1, 313.1, 413.1, 513.1, 613.1) capable of resting in either of 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 changing from the biased state (S2) into the relaxed state (S1), thereby generating an audible signal, wherein the resilient force member (313.1, 413.1, 513.1) is supported by a retaining element (10, 15.2, 110, 210, 310, 410, 510, 610) in the biased state (S2) in order to prevent transition into the relaxed state (S1).本發明涉及一種與藥劑輸送裝置(1，101，201，301，401，501，601)組合的聲響指示器(13，113，213，313，413，513，613)，包括能夠停留在以下兩種狀態(S1，S2)任一種的彈性力部件(13.1，113.1，213.1，313.1，413.1，513.1，613.1)，-其中在偏置狀態(S2)中，彈性力部件(13.1，113.1，213.1，313.1，413.1，513.1，613.1)被偏置並儲存能量，-其中在鬆弛狀態(S1)中，彈性力部件(13.1，113.1，213.1，313.1，413.1，513.1，613.1)鬆弛，和-其中當所述彈性力部件(13.1，113.1，213.1，313.1，413.1，513.1，613.1)從偏置狀態(S2)改變到鬆弛狀態(S1)時釋放所儲存的能量，由此產生了聲響信號，其中該彈性力部件(313.1，413.1，513.1)由保持元件(10，15.2，110，210，310，410，510，610)支承在偏置狀態(S2)，從而防止向鬆弛狀態(S1)的轉變。
