A Tonpilz type transducer has been designed and fabricated using grain oriented Tb 0.3 Dy 0.7 Fe 1.95 magnetostrictive rods as active elements. The design include provisions for DC biasing of the active elements with the help of an array of resin-bonded Nd-Fe-B ring magnets, AC drive coil and a pre-stressing mechanism. Resonance frequency of this transducer was found to be 1.6 kHz. A Transmitting Current Response (TCR) of 167 dB ref 1μPa/A at 1 m and a Transmitting Power Response (TPR) of 152 dB ref lμPa/W were achieved. The Source Level (SL) was determined to be 177 dB ref μPa at 1m.
