Provided are marine acoustic vibrators and methods of using marine acoustic vibrators. An example marine acoustic vibrator (5) comprises a sound radiating surface (25) operable to produce a resonance frequency, wherein the sound radiating surface at least partially defines a marine acoustic vibrator internal volume, wherein the marine acoustic vibrator internal volume comprises a marine acoustic vibrator internal gas having a marine acoustic vibrator internal gas pressure; a compliance chamber (10), wherein the compliance chamber comprises a compliance chamber internal volume, and a spring function system (53); a linear motor (90) operable to adjust the compliance chamber internal volume; wherein pressure variations in the marine acoustic vibrator internal volume generated by actuation of the sound radiating surface induce the spring function system and the linear motor to adjust the compliance chamber internal volume such that the pressure variations in the marine acoustic vibrator internal volume are reduced. |
