A device for repelling animals using acoustic waves, comprising an acoustic wave generation unit (11); first and second frequency adjusting units (12, 13) to induce the generation of resonance of the pulse signal generated from the acoustic wave generation unit (11); an acoustic wave output unit (14) to output the acoustic wave; a resonance generation-type acoustic wave output unit (15) to output the acoustic wave; a resonance generation unit (16) which forms a space in which the acoustic wave outputted from the acoustic wave output unit (14) and the acoustic wave outputted from the 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. |
