摘要

PROBLEM TO BE SOLVED: To provide a deer repellent sound-generating device that can generate a deer repellent sound capable of effectively repelling deer, and to provide a deer intrusion prevention system in a railroad track using the deer repellent sound-generating device, and to provide a vehicle using the deer repellent sound-generating device.;SOLUTION: A deer repellent sound-generating device 10 can emit a sweep sound having frequency change with passage of time from a speaker 20 connected with the deer repellent sound generating device 10 at least in a partial frequency range of a frequency range of 1 kHz or more and 10 kHz or less. The deer repellent sound-generating device 10 is installed in an operator's cab of a train vehicle and the speaker 20 is installed in a front part of the vehicle, and a deer repellent sound is emitted during traveling of the train. Alternatively, the deer repellent sound-generating device 10 is installed around a railroad track, and the deer repellent sound is emitted from the speaker 20 to the habitat of the deer by the deer repellent sound-generating device 10.;COPYRIGHT: (C)2015,JPO&INPIT
