Abstract

Cymbal transducers are often used as an array rather than single because they have a high quality factor and low energy conversion efficiency. When used as an array, there occurs a big change in the frequency characteristics of the array due to the interaction between constituent transducers. In this study, we designed the structure of a cymbal transducer array to have ultra-wideband characteristics using this property. First, cymbal transducers with specific center frequencies were designed. Then, a 2x2 planar array was constructed with the designed transducers, where the cymbal transducers were arranged to have same or opposite polarization directions. For this structure, we analyzed the effect of the difference in the center frequency of and the spacing between the constituent transducers on the acoustical characteristics of the array. Based on the analysis, we designed the structure of the cymbal transducer array to have the widest possible bandwidth.
宽带钹换能器阵列的设计
钹式换能器通常用作阵列而不是单个,因为它们具有高质量因子和低能量转换效率。当用作阵列时,由于各组成换能器之间的相互作用,阵列的频率特性会发生很大的变化。在这项研究中,我们设计了一个钹换能器阵列的结构,利用这一特性具有超宽带特性。首先,设计了具有特定中心频率的钹换能器。然后,将所设计的换能器构建为2x2平面阵列,其中钹形换能器排列成相同或相反的极化方向。针对这种结构,我们分析了各组成换能器之间的中心频率差和间距对阵列声学特性的影响。在此基础上,我们设计了钹换能器阵列的结构,使其具有尽可能宽的带宽。
