a spring element configured to reside in one of a relaxed state and a biased state; and
a rotatable element coupled to the spring element and rotatable about a pivot,
wherein the rotatable element is configured to impact a surface,
wherein the spring element and the rotatable element are arranged such that, when the spring element releases stored energy, the rotatable element rotates and is configured to impact the surface to generate an audible signal when the spring element changes from the biased state into the relaxed state,
wherein the spring element is engaged in a slot within the rotatable element, and
wherein the spring element is a sheet metal part.
