Abstract
An apparatus and method for securing a piezoelectric element in an electroacoustic communications node used in a downhole wireless telemetry system. An end mass is secured to the piezoelectric element. At least one fastener attaches a pre-tensioning support plate to a housing of the node. The pre-tensioning support plate and the at least one fastener impart a tensioning force to the end mass and/or the piezoelectric element when the pre-tensioning support plate and the end mass and/or the piezoelectric element are secured to the housing.
