Harmful animal repeller having a ultra cardioid directivity loudspeaker being rotated toward a direction of detected sound

摘要

[0001] The present invention relates to a pest suppressor having a supergain loudspeaker rotated in the direction of a sensed sound, a super directional loudspeaker capable of detecting sound from a plurality of directional microphones installed on the north, south, The direction of the sound of the directional microphone in which the loudest sound signal is detected is detected, and the rotation angle of the directional microphone is detected according to the control of the control unit. Directional speaker in the direction of the sound detected by the controlled motor drive and modulates the sound signal for eliminating the animal from the supergiant speaker rotated in the direction of the sensed sound and transmits it to the ultrasonic signal, As the sound is emitted with the directivity in the specific direction shown, The effect of chasing animals to reduce the damage of my crops.
