With features of half-space sound field radiation and the receiving characteristic, Hemispherical deep-water transducer can work 6000 meters underwater in depth under the condition of the pressure balance principle. Hemispherical deep-water transducer can be used in underwater vertical channel acoustic communication system, response releasing instrument and USBL positioning system.
