1. An injection device for injecting a dose of a medicament, the injection device comprising:
an acoustic feedback arrangement comprising:
a first feedback element having a first engaging section;
a second feedback element having a second engaging section configured to engage with the first engaging section;
wherein the first feedback element is movable, pivotable or resiliently deformable along a first direction relative to the second feedback element from an initial state towards a biased state; and
a sound generator formed by the first engaging section, wherein the first engaging section is configured to audibly engage with the second engaging section when the first feedback element returns from the biased state to the initial state,
wherein the second feedback element is configured to transfer the first feedback element from the initial state towards the biased state, and
wherein the first feedback element is transferable from the initial state towards the biased state through mechanical engagement of the first engaging section with the second engaging section.
