1. An acoustic device assembly comprising:
a housing comprising a spacing element;
a piezo element comprising a piezoelectric material, wherein the piezo element is coupled to the housing; and
an at least partially flexible acoustic coupler coupled to the housing and including a first portion configured to contact tissue of a user,
wherein the first portion of the acoustic coupler includes an outer protrusion disposed on an outside surface of the acoustic coupler,
wherein the piezo element is spaced from the acoustic coupler by the spacing element, and
wherein the piezo element is coupled to the acoustic coupler by a coupling element configured to apply pressure to the piezo element so as to bias the piezo element in tension.
