  • Electrodynamic transducer for underwater acoustics
    Patent number: 6515940
    Abstract: Disclosed is an electrodynamic transducer designed to emit acoustic waves in a sea environment while being capable of withstanding external explosions. The lower pole piece of such a transducer is drilled with vertical holes enabling air to circulate inside the transducer in order to efficiently cool the coil that makes it work. Light metal masses that are good heat conductors, attached between the magnets which excite the pole pieces, furthermore drain the heat out of the transducer. The efficiency of such a transducer is increased by at least 4.
    Type: Grant
