Abstract

The invention relates to a device whose near-infrasonic transmitted mechanical vibrations render the habitat of hulls or submerged objects undesirable to limpets, barnacles and other molluscs. Diagrammatically, it consists of two half-shells 10 and 11 forming a small-sized sealed casing which contains an electromagnetic resonator 1 having a moving coil 2, of low electrical consumption, supplied externally from any low-voltage sourse. The resonant oscillation maintained by the electronic unit 3 is mechanically transmitted to the protected object 4 by the single means of attachment 5. The device according to the invention is particularly intended for the protection of small- and medium-sized craft.
