The article is dedicated to the research of the influence made by secondary modes of oscillations on the uniformity of distribution of the oscillations produced by the ultrasound disk radiators. The article considers the reasons for emergence of the secondary oscillation modes and the ways of mitigating the influence of the secondary modes on the final distribution of the oscillations of the ultrasound disc radiator. It is pointed out that the difference between the working mode frequency and the secondary flexural mode should be 500 Hz or above, and the minimum difference between the working mode and the secondary radial mode frequencies should be 2 kHz. The article also presents the results of the studies of the disc radiators with anisotropic mechanical properties. It suggests a method for modernization of the disc radiators featuring anisotropic mechanical properties in various ways.
