sonar boomer transducer

sonar boomer transducer

[′sō‚när ′büm·ər trans‚dü·sər] (engineering acoustics) A sonar transducer that generates a large pressure wave in the surrounding water when a capacitor bank discharges into a flat, epoxy-encapsulated coil, creating opposed magnetic fields from the coil and from eddy currents in an adjacent aluminum disk, which cause the disk to be driven away from the coils with great force.
