1. An apparatus comprising:
a downhole acoustic measurement tool comprising:
at least one transducer operable for emitting acoustic excitation signals and/or receiving echo signals to perform downhole measurements;
a backing in contact with an inner surface of the at least one transducer;
a first structure mechanically coupled to a first housing;
a second structure mechanically coupled to a second housing; and
a longitudinally extending member comprising:
a first portion mechanically coupled to the first structure;
a second portion mechanically coupled to the second structure, wherein at least one of the first and second structures is mechanically coupled to the member and thereby has a longitudinal degree of freedom relative to the member; and
a third portion extending longitudinally through the backing between the first and second portions such that compressional longitudinal forces experienced by the first and second housings are transferred through the first and second structures and the backing.
