Abstract

Embodiments relate to marine seismic vibrators and associated methods of use. An embodiment provides a marine seismic vibrator comprising: a shell comprising endbeams and shell side portions coupled to the endbeams, wherein each of the shell side portions has a midline between the endbeams, wherein each of the shell side portions has a thinner portion at the midline to force each of the shell side portions to bend at the midline; a driver disposed within the shell; and a pair of spring elements disposed within the shell on either side of the driver, wherein the pair of spring elements are coupled to the driver and to the shell such that movement of the driver is transferred to the shell by way of the spring elements, wherein the pair of spring elements have a second mode of oscillation that provides a second resonance frequency within the operational frequency range.
