Abstract
Electroacoustic system repelling rodents and noxious animals, characterized in that it consists of a main electronic unit (uep), which generates variable electrical impulses or signals, with a frequency between approximately 16,000 to 23,000 hz, whose frequency may vary with time, the signal intensity can also be varied by sweeping through the aforementioned range of frequencies, if the first of the three generation circuits that the system will be equipped with is used, while if the second one is used, the generation will be will be based on a white noise generator including a bandpass filter previously to the amplification chain, if the third of the circuits is used, the generation will be made using the loop feedback effect based on microphonic elements, installed in the area of ultrasonic emission and also intercalating a bandpass filter previously to the amplification circuits, producing the connection of one to another of the circuits, manually by means of a three-position switch located in the (uep).
