| dc.description.abstract | 水聽器是一種專門設計用來檢測水下聲波的裝置,廣泛應用於海洋監測、聲納系統和水下通訊等領域,基於壓電效應,能夠將接收到的聲壓信號轉換為電信號,並依據不同的設計和材料呈現出不同的靈敏度和頻率響應特性。本研究以探討壓電式圓管水聽器的低頻工作頻率以及接收靈敏度為主,對其內部的壓電材料進行軟體上分析,以不同的尺寸、陶瓷和複合材料以及包覆在壓電管外的材料做一系列「阻抗分析」、「接收靈敏度」、及「指向性」的模擬與討論,最終建立的水聽器設計想法,對各種水下環境中的聲學探測需求給予應對。 | zh_TW |
| dc.description.abstract | Hydrophone is a device specially designed to detect underwater sound waves. It is widely used in the fields of ocean monitoring, sonar systems and underwater communications. Based on the piezoelectric effect, it can convert the received sound pressure signal into an electrical signal, and exhibit different sensitivity and frequency response characteristics based on different designs and materials. This study focuses on exploring the low-frequency operating frequency and receiving sensitivity of the piezoelectric circular tube hydrophone. Conduct a series of simulations and discussions on "Impedance analysis", "Receiving sensitivity", and "Directivity" using different sizes, ceramic and composite materials, and materials covering the piezoelectric tube., and finally the hydrophone design idea was established to respond to the acoustic detection needs in various underwater environments. | en |
