A marine vibrator (5) may include a containment housing (135), a sound radiating surface (21), and a compliance chamber (10). The compliance chamber (10) may include a compliance chamber housing, a non-linear linkage assembly (85), and a low pressure chamber (70). The compliance chamber housing may define at least a portion of a compliance chamber internal volume having a compliance chamber internal gas pressure. The low pressure chamber may comprise a low pressure piston (75) and a low pressure chamber housing (76). The low pressure chamber housing (76) may define at least a portion of a low pressure chamber internal volume having a low pressure chamber internal gas pressure. The low pressure piston may be configured to move in response to a pressure differential across the low pressure piston such that a resonance frequency of the marine vibrator may be changed. |
