ABSTRACT:
Disclosed is an electrodynamic transducer designed to emit acoustic waves in a sea environment. The dome of a transducer such as this is provided with a horn sliding in the body of the transducer with an adjutage whose clearance is extremely small. This reduces the effects of a shock wave coming from a possible external explosion and prevents the tearing of the tight-sealing membrane between the horn and the body. Radial ribs increase the stiffness of this mobile structure. A toroidal, elastic air chamber provides compensation for the effects of the hydrostatic pressure and of gravity on the mobile structure. The disclosure provides transducers that are resistant to external explosions.
