Zusammenfassung:rodent repelling equipment. SUBSTANCE: apparatus has signal generator and piezoelectric emitters for generating supersonic field. Signal generator has casing, for instance rectangular, comprising rectifier, pulse-frequency modulator, basic frequency generator, noise signal generator, inverter, delay generator, and output cascade. Piezoelectric emitters are provided with megaphone and are made of outside type. Apparatus is designed for preventing objects to be damaged by rodents by repelling effect of supersonic field and may be used in stores, grain storages, premises of food-processing industry, in shops and houses, as well as in municipal services, cable, telephone and other communication systems. Construction of apparatus prevents rodents from adaptation to emitted signal. EFFECT: increased efficiency and simplified construction. 1 dwg
