    • A coherent sound source is provided for marine seismic surveys. An underwater sound projector for producing time-harmonic waveforms comprises two pistons positioned on either side of a single electro-magnetic force generator substantially having mechanical and magnetic symmetry about its geometric center to substantially cancel reaction loads that occur when the pistons are actuated. The underwater sound projector optionally also includes control systems to improve the fidelity of the force generator, provide pressure compensation to the pistons, finely adjust the static position of the pistons, and change the depth and roll when it is configured as tow body. A plurality of underwater sound projectors can be configured in an array. A load-bearing umbilical can connect the underwater sound projectors to a ship, transmit electrical power to each array element and serve as a duplex data transmission medium to route commands from the ship to the projector and report machinery status.
    • 为海洋地震勘测提供了一个连贯的声源。 用于产生时间谐波波形的水下声音投影仪包括位于单个电磁力发生器的两侧的两个活塞,其基本上具有围绕其几何中心的机械和磁对称性,以基本上消除活塞被致动时发生的反作用负载。 水下声音投影仪还可选地包括控制系统,用于提高力发生器的保真度,为活塞提供压力补偿,精细地调整活塞的静态位置,并在配置为拖曳体时改变深度和滚动。 多个水下声音投影仪可以被配置成阵列。 负载脐带可以将水下声音投影仪连接到船上,将电力传输到每个阵列元件并用作双工数据传输介质,以将命令从船舶发送到投影仪并报告机器状态。

    • A coherent sound source is provided for marine seismic surveys. An exemplary underwater sound projector comprises a plurality of pistons actuated by an electromagnetic force generator having components comprising a stator, armatures, electrical coils, and permanent magnets. The pistons and the components are arranged to create mechanical and magnetic symmetry about a geometric center of the projector to reduce reaction loads that occur when the pistons are actuated. The stator and the armatures have magnetic poles that employ a tapered geometry. The projector optionally includes control systems to improve the fidelity of the force generator, provide pressure compensation to the pistons, finely adjust the static position of the pistons, and/or change the depth and roll when the projector is configured as a tow body. A plurality of such projectors can be configured in an array. An umbilical can connect the projectors to a vessel, transmit electrical power and compressed gas to each array element and/or provide a data transmission medium between the projector and the vessel.
    • 为海洋地震勘测提供了连贯的声源。 示例性的水下声音投影仪包括由电磁力发生器致动的多个活塞,其具有包括定子,电枢,电线圈和永磁体的部件。 活塞和组件被布置成围绕投影仪的几何中心产生机械和磁性对称,以减少当活塞被致动时发生的反作用力。 定子和电枢具有采用锥形几何形状的磁极。 投影仪可选地包括控制系统,以提高力发生器的保真度,向活塞提供压力补偿,精细地调节活塞的静态位置,和/或当投影机配置为丝束体时改变深度和滚动。 可以将多个这样的投影仪配置成阵列。 脐带可以将投影仪连接到容器,将电力和压缩气体传输到每个阵列元件和/或在投影仪和容器之间提供数据传输介质。
