摘要： A transducer assembly holder is mounted through the wall of a fluid conveying structure and includes an acoustic window in communication with the fluid. A transducer assembly is positioned within the holder and has a transducer active element encapsulated in an elastomeric material. The assembly is positioned up against the window of the holder and a spring force is applied to the assembly through a spacer tube or rod. The arrangement is such that the spring force is transferred evenly over the encapsulating elastomeric material and a pressure bond is created between the transducer active element and the acoustic window, such couplings being essential for proper transducer operation.

摘要： Three posts mounted on the underside of a ship transmit acoustic signals to and from one another for computation of ship''s speed. The posts are streamlined for traveling through the water and each includes at the lower end thereof a streamlined housing having a cavity in which is positioned a transducer assembly. The cavity is covered by a thin acoustic window along the streamlined surface. Water is introduced between the transducer assembly and the window for proper signal coupling such that a propagated acoustic signal is properly transmitted to the transducer assembly in another post. Due to the streamlining, the acoustic signals impinge at different angles upon at least two of the posts and the acoustic windows for these two different posts are of different materials and carefully chosen to insure proper signal reception.
摘要翻译：安装在船的下侧的三个柱子彼此传递声信号以计算船的速度。柱被流线化以便穿过水，并且每个在其下端包括具有空腔的流线型壳体，其中定位有换能器组件。空腔由流线型表面的薄的声窗覆盖。在换能器组件和窗口之间引入水以进行正确的信号耦合，使得传播的声信号在另一个柱中适当地传递到换能器组件。由于精简，声信号在至少两个柱和两个不同柱的声窗之间以不同的角度入射，并且被仔细选择以确保适当的信号接收。
