| Popis: | A new type of cymbal transducer, called the concave cymbal, has been developed to increase the pressure tolerance and reliability of the transducer under high hydrostatic pressure. The main feature of the new design is a lead zirconate titanate ceramic ring sandwiched between two concave metal endcaps. It shows much improved pressure performance and can withstand a pressure of up to 6 MPa while maintaining high effective hydrostatic piezoelectric coefficients. When incorporated into a planar array with a radiating area of 5.5 cm/spl times/5.5 cm and weight of only 30 g, a transmitting voltage response of around 125 dB re 1 /spl mu/Pa/V@1 m was obtained over a frequency range between 20 and 50 kHz. |
