JP2001120158A - Device for generating sound for repelling animal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an animal-repelling sound generation device which is used for preventing that harmful animals approach an arable, an afforestation area or the like. SOLUTION: This animal-repelling sound generation device comprises an electric source and a piezoelectric buzzer for generating arbitrary audible sounds of 3 to 5 kHz. The animal-repelling sound generation device comprises an electric source, an oscillator, an amplifier, and a speaker, and generates arbitrary or continuously variable audible sounds of 3 to 5 kHz.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beast-repelling sound generating device for keeping pests from approaching cultivated lands, plantations and the like.

[0002]

BACKGROUND OF THE INVENTION Conventionally, there is no effective method for damaging pests on agricultural crops such as monkeys, bears, antelopes, etc., which has become a social problem. There are many types of sensors that use various sensors to detect explosive sounds, onomatopoeic sounds, ultrasonic waves, and non-audible sounds in order to repel the beast. Many are not shown and none are practical.

[0003]

[Technical issues that we attempted to develop] Experiments were performed in various ways, but it was found that the effect was weak after the beast appeared in any method. The present invention relates to an unprecedented beast-repelling sound generation device for the purpose of always generating a sound that the beast dislikes and not approaching the vicinity of the cultivated land, instead of repelling the beast that appeared in the past with threats or the like. .

[0004] The present invention is 3 to 5 KHz that humans hate
It was completed by making a sound generator and experimenting with a beast.

[0005]

Configuration of the Invention

A piezoelectric buzzer 1 for generating an arbitrary audible sound of 3 to 5 KHz shown in FIG.

As shown in FIG. 2, an oscillator 3, an amplifier 4, a speaker 5, and a power supply 6 for generating an audible sound varying arbitrarily or continuously from 3 to 5 KHz.

[0007]

The beast repellent sound generating device shown in FIG. 1 or 2 is installed in a cultivated land, an afforestation area or the like.

Although it is possible to limit the time with an optical sensor or a timer, it is not desirable because the present invention aims to create an environment that always generates sound and is inaccessible.

[0009]

[Effect] Mammals have auditory organs and frequency bands relatively similar to humans. The repellent sound of the present invention is a sound that also gives disgust to humans, and a beast with a sharp hearing responds greatly. In particular, when the piezoelectric buzzer 1 and the speaker 5 are directed to a passage of a beast called an animal trail, the effect is great.

In experiments at a frequency of 3.5 KHz, monkeys,
Bears and antelopes did not appear at all, and the objective was completely achieved.

The sound of 3 to 5 KHz is a frequency obtained in an experiment, and it is unclear what physiological response the beast has, and it is necessary to leave it to the research of an expert, but it is not intended by the present invention. The object of the present invention is to be achieved.

Depending on the type of beast, sounds of 5 KHz or more are considered to be more effective, but they are also not practical because they strongly dislike humans.
