摘      要：In this study,a 2kHz Tonpilz projector was designed using a Terfenol-D and modeled in *** the purpose of modeling studies,it has been determined that a radiating head mass exhibits better transmitting current response（TCR） at 136 mm diameter,where the resonance occurs at 2.4kHz and the peak value of 118 dB re 1 μPa/A at 1 m occurs at 12 *** bolt at a 46mm distance from the center of the head mass offers resonance at 2.4kHz,and the peak value of 115.3 dB re 1 μPa/A at 1m occurs at *** optimized design is fabricated and molded with polyurethane of 3mm *** prototype was tested at the Acoustic Test Facility（ATF） of National Institute of Ocean Technology（NIOT） for its underwater *** on the result,the fundamental resonance was determined to be 2.18kHz and the peak value of TCR of 182 dB re 1 μPa/A at 1m occurs at 14 *** maximum value of the RS was found to be -190 dB re 1V/μPa at 1m at a frequency of 2.1kHz.
