Abstract
Disclosed are apparatuses, systems, and methods for use of an acoustic projector. An embodiment discloses an acoustic projector comprising a fixed plate; a first bender plate coupled to a first side of the fixed plate; a second bender plate coupled to a second side of the fixed plate, opposite to the first side; a first driver coupled to the first side of the fixed plate and to the first bender plate to oscillate the first bender plate; and a second driver coupled to the second side of the fixed plate and to the second bender plate to oscillate the second bender plate.
Claims20
An acoustic projector comprising:
- a fixed plate;
- a first bender plate coupled to a first side of the fixed plate;
- a second bender plate coupled to a second side of the fixed plate, opposite to the first side;
- a first driver coupled to the first side of the fixed plate and to the first bender plate to oscillate the first bender plate;
- and
- a second driver coupled to the second side of the fixed plate and to the second bender plate to oscillate the second bender plate.
A method for marine seismic surveying, comprising:
- towing an acoustic projector through a body of water, wherein the acoustic projector comprises:
- a fixture;
- a first bender plate attached to a first side of the fixture;
- a second bender plate attached to a second side of the fixture, opposite to the first side;
- a first driver attached to the first side of the fixture and to the first bender plate;
- and
- a second driver attached to the second side of the fixture and to the second bender plate;
- actuating the first driver to cause the first bender plate to flex to generate a first sound wave emanating from the acoustic projector;
- and
- actuating the second driver to cause the second bender plate to flex to generate a second sound wave emanating from the acoustic projector.
A method of operating an acoustic projector, comprising:
- selecting a mode of operation for the acoustic projector, wherein the mode is selected from at least one of monopole operation or dipole operation, wherein the acoustic projector comprises, a first bender plate, a second bender plate, a first driver attached to the first bender late, and a second driver attached to the second bender plate;
- sending current to the first driver and the second driver to implement the selected mode of operation;
- and
- flexing the first bender plate with the first driver to generate a first sound wave;
- and
- flexing the second bender plate with the second driver to generate a second sound wave.
