BROADBAND ULTRASOUND ELECTROACOUSTIC TRANSDUCER WITH CIRCULAR PATTERN FOR RODENT REPELLENT DEVICES

摘要

FIELD: rodent repellent devices.;SUBSTANCE: invention can be used in rodent repellent devices in domestic and industrial premises. Broadband ultrasound electroacoustic transducer with a circular pattern for rodent scaring devices consists of an emitter with ultrasonic actuators attached to it. Emitter is made in the form of bent metal plate. Ultrasonic actuators are arranged inside emitter bend and have different resonant frequencies.;EFFECT: higher efficiency of rodent repellent due to formation of circular pattern of directivity of ultrasonic radiation without dead zones not covered with ultrasonic irradiation, and expansion of number of resonance frequencies of device, and also simplification of manufacturing.;1 cl, 2 dwg
