Creating a broadband tonpilz transducer that operates efficiently at low frequencies presents a significant challenge. The objective of this study is to develop a high-power tonpilz transducer with enhanced broadband performance by optimizing the radiating plate. Further refinement is conducted to achieve the widest possible bandwidth without compromising voltage transfer performance. The study examined how variations in the radiating plate structure affect the overall transducer performance using finite element analysis (FEA) and experimental methods. By drilling holes in the radiating plate, an optimal bandwidth of 28,07% was achieved with 16 holes, while the tactile vibration response (TVR) of the transducer was reduced from 9,61 dB to 6,39 dB re 1 mPa/V. Furthermore, the generated model exhibited resonance, demonstrating strong agreement between the FEA modeling and the physical prototype. Thus, experimental verification during the transducer prototype development validates the proposed design improvements.
