为了实现深海远距离探测和通信，要求水下换能器具有低频宽带特性，本文提出一种新型管梁耦合水声换能器设计方案。该换能器在常规管梁耦合结构中心引入激励振子与质量块，构建双驱动架构，优化有效工作模态，增强辐射响应，有效地减小了尺寸，扩展了带宽。优化后换能器的发射电压响应在起伏3 dB上的工作频率区间为3.5～8 kHz，工作带宽为4.5 kHz，平均幅值为127 dB。
In order to achieve long-distance deep-sea detection and communication, underwater transducers are required to have low-frequency broadband characteristics. This paper proposes a new design scheme of tube-beam coupled underwater acoustic transducer. This transducer introduces an excitation oscillator and a mass block at the center of the conventional tube-beam coupling structure to construct a dual-drive architecture, optimize the effective working mode, enhance the radiation response, and effectively reduce the size and expand the bandwidth. The operating frequency range of the transmission voltage response of the optimized transducer with a fluctuation of 3 dB is 3.5～8 kHz, the operating bandwidth is 4.5 kHz, and the average amplitude is 127 dB.
