膜片
用作极式安装座组件一部分的谐振圆盘。膜片按弯曲模式调谐，并安装在波腹处（一个膜片位于换能器—增幅杆接头处，另一个位于增幅杆—变幅杆接头处）。由于膜片已调谐，它可以阻止声能从叠堆逸散到支撑结构（如焊接机架）。
Diaphragm
A resonant disk that is used as part of a polar mount assembly. The diaphragm is tuned in flexure and is positioned at an antinode (one diaphragm at the transducer-booster joint and another at the booster-horn joint). Because it is tuned, the diaphragm prevents the escape of acoustic energy from the stack to the support structure (e.g., the welding stand).
