    • A marine vibrator has a housing that comprises a displacement member, the displacement member having a first position and a second position, the housing and the displacement member together defining an internal volume. A linear electromagnetic motor interacts with the displacement member so as to move the displacement member between a first position and a second position and correspondingly strokes the displacement member to cover a volume. The linear electromagnetic motor comprises magnets and coils that when energized create an electromagnetic force there between, wherein the linear electromagnetic motor comprises a piston and a guide that substantially surrounds the piston. The piston has incorporated therein either the coils or the magnets, and the guide having incorporated therein the other of the coils or the magnets. The piston is in interaction with the displacement member.
    • 海洋振动器具有包括位移构件的壳体,所述位移构件具有第一位置和第二位置,所述壳体和所述位移构件一起限定内部容积。 线性电磁马达与位移构件相互作用,以使位移构件在第一位置和第二位置之间移动,并且相应地对位移构件进行冲击以覆盖体积。 线性电磁马达包括磁体和线圈,当通电时,线圈电磁马达在其间产生电磁力,其中线性电磁马达包括活塞和基本上围绕活塞的引导件。 活塞在其中并入线圈或磁体,引导件结合有另一个线圈或磁体。 活塞与位移构件相互作用。
