The cymbal transducer is a miniature transducer developed from the class V flextensional transducer. Many studies to analyze this transducer have been conducted using either the finite element method or fabrication and measurement technique. Meanwhile, the equivalent circuit method is a relatively simpler, faster, and more efficient approach to conduct performance analysis of an electromechanical transducer compared with these two methods. However, despite this merit, an accurate equivalent circuit model has not been introduced for the cymbal transducer, yet. In this study, we developed a novel equivalent circuit that can accurately depict the characteristics of the cymbal transducer and enable its efficient performance evaluation. The equivalent circuit was first divided into several parts according to the structure of the transducer. Thereafter, the electromechanical and vibration characteristics of each part were analyzed to derive the values of the circuit parameters corresponding to the part. The validity of the circuit parameters was verified by comparing the impedance calculated with the circuit comprising the parameters and that measured with prototype transducers. Additional analysis of the transmitting voltage response of the transducer further confirmed the efficacy and accuracy of the developed equivalent circuit in characterizing the cymbal transducer. The new equivalent circuit developed in this work can facilitate the design and analysis of not only individual cymbal transducers but also their large arrays.

铙钹换能器等效电路的开发


铙钹式换能器是由V类弯张换能器发展而来的微型换能器。已经使用有限元方法或制造和测量技术进行了许多分析该传感器的研究。同时，与这两种方法相比，等效电路法是一种相对简单、快速、高效的机电换能器性能分析方法。然而，尽管有此优点，但尚未为铙钹换能器引入准确的等效电路模型。在这项研究中，我们开发了一种新颖的等效电路，可以准确地描述铙钹换能器的特性并实现其有效的性能评估。首先根据换能器的结构将等效电路分为几个部分。此后，分析每个部件的机电和振动特性，得出该部件对应的电路参数值。通过比较包含参数的电路计算的阻抗和原型传感器测量的阻抗，验证了电路参数的有效性。对传感器发射电压响应的额外分析进一步证实了所开发的等效电路在表征铙钹传感器方面的功效和准确性。这项工作中开发的新等效电路不仅可以促进单个铙钹换能器及其大型阵列的设计和分析。
