The present invention relates to a device for repelling animals using acoustic waves, and specifically, to a device for repelling animals using acoustic waves, wherein to amplify and diffuse an acoustic wave band repellent to animals so as to prevent damage to crops by wild animals, accidents involving telephone poles, accidents occurring during take-off and landing of airplanes, and accidents occurring on the tracks of high-speed trains, the invention comprises: an acoustic wave generation unit (11) which generates an electric pulse signal first and second frequency adjusting units (12, 13) which adjust frequencies in order to induce the generation of resonance of the pulse signal generated from said acoustic wave generation unit (11) an acoustic wave output unit (14) which converts the pulse signal outputted via said first frequency adjusting unit (12) into an acoustic wave, and outputs the acoustic wave a resonance generation-type acoustic wave output unit (15) which converts the pulse signal outputted via said second frequency adjusting unit (13) into an acoustic wave, and outputs the acoustic wave a resonance generation unit (16) which forms a space in which the acoustic wave outputted from said acoustic wave output unit (14) and the acoustic wave outputted from said resonance generation-type acoustic wave output unit (15) stay at the same time, and amplifies the volume and the frequencies by inducing resonance to be generated by mutual interference and an acoustic wave diffusing unit (17) which diffuses the acoustic waves expanded by the resonance to a free space via an induction pathway.La présente invention concerne un dispositif permettant déloigner des animaux à laide dondes acoustiques. Pour amplifier et diffuser une bande dondes acoustiques éloignant les animaux de façon à prévenir des dommages réalisés par des animaux sauvages sur les récoltes, des accidents faisant intervenir des poteaux téléphoniques, des accidents se produisant lors du décollage et d
