Abstract
An apparatus for generating acoustic waves in an aquatic environment through the use of linear motors mounted on a frame is disclosed herein. The linear motors can reciprocate at a first frequency which is transmitted through a transmission element and to a sound emitting surface. The structure of the apparatus can generate acoustic waves across a broad frequency to measure subterranean formations.
Claims10
A drive assembly for acoustic sources, the drive assembly comprising:
- at least one vibrating surface capable of being set in vibrational motion;
- a frame including at least one linear motor;
- two or more flexible transmission elements connecting between fastening devices and extending on both sides of an axis, between the two fastening devices;
- at least one spring element connected to the two or more flexible transmission elements, wherein the at least one spring element is configured to introduce a resonance mode different from a resonance mode of the flexible transmission elements;
- the at least one linear motor being connected to the transmission elements, and adapted to provide a controlled oscillating motion;
- and
- a sound emitting surface connected to the fastening devices.
