Abstract
The disclosure herein generally relates to a device for use in marine seismic surveying. A displacement apparatus has a base and an actuated head. The actuated head is coupled to an actuation means comprising a shaft, a cam, and a motor. The cam is coupled to the shaft at a radial position from the center of the cam. A vacuum piston is optionally coupled to the actuation means. A variable resonance spring, such as an air spring, is coupled to the actuated head in order to tune the apparatus to operate in resonance at a range of frequencies.
