본 고안은 중학교 또는 고등학교에서 학습용 교제로 사용되는 기주공명 장치에 관한 것이다.The present invention relates to a host resonance device used as a learning companionship in middle or high school.

지금까지 음의 진동수를 측정하기 위하여 학습용 교재로 사용되고 있는 기주 공명 장치는 수동식이므로 그 실험에 2-3명의 인원이 필요하고 또한 정확도의 면에서도 다소 문제가 있으며 따라서 학습용 실험 교재로써 다소 불편한 점이 있었다. 본 고안은 이러한 문제점을 해결하고자 안출된 것이다.So far, the host resonance apparatus used as a teaching material for measuring the frequency of sound is a manual type, so it requires 2-3 people for the experiment and also has some problems in terms of accuracy. The present invention is designed to solve this problem.

본 고안은 공기주의 상단부에 위치한 발성체를 전자킷트(KIT)를 이용한 자동발성 장치로 구성하여, 종래의 소리굽쇠에 의한 수타식 발성체의 결점을 보완하며, 고음을 발생시킨 후 공기주내에서 그 음과 공명을 이루는 점을 찾기 위하여 사용되는 수주의 높이 조절을 유량 조절 가능한 물펌프를 이용하여 용이하게 진동수를 측정할 수 있다는 점에 특징이 있다. 본 고안을 보다 잘 이해하기 위하여 도면을 참고로하여 설명하고자 한다.The present invention consists of an automatic voice device using an electronic kit (KIT) located at the upper end of the air column, which compensates for the shortcomings of the manual voice type by the conventional tuning fork, and generates the high sound and then the sound in the air column. It is characterized by the fact that the height of the water column, which is used to find the point of resonance and resonance, can be easily measured using a water pump with a flow rate control. In order to better understand the present invention, it will be described with reference to the drawings.

제1도에 도시된 바와같이 본고안 장치는 기주(1)및 그 상단에 설치된 발성체(2), 그리고 기주(1)내에서 발생된 음과 공명을 이루는 점을 찾기 위하여 물을 공급하는 소형 물펌프(P)로 구성된다. 미설명부호 P는 물펌프를 표시한다. 본 고안의 기본적인 원리는 공지된 학습교재용 기주 공명장치와는 차이가 없으나 발성체가 전자킷트로 대체되어 일정한 고음을 유지하며, 기주속으로 공급되는 물이 전원장치 및 물펌프를 이용하여 손쉽게 공명을 이루는 점을 찾을 수 있다는 특징이 있다. 종래에는 물펌프 대신에 고무 호스 등으로 연결된 큰 비이커등에 물을 가득 채운 뒤 높이를 손으로 조절하면서 공명을 이루는 높이를 측정하는 점을 개량한 것이다. 따라서 기주의 하단에서 부터 채워지는 물기둥의 높이를 손쉽게 측정할 수 있는 것이다.As shown in FIG. 1, the device of the present invention is a compact apparatus for supplying water to find the point of sound and resonance generated in the host 1 and the speaker 2 installed at the top thereof. It consists of a water pump (P). Unexplained symbol P denotes a water pump. The basic principle of the present design is not different from the host resonance apparatus for the teaching materials. However, the speaker is replaced with an electronic kit to maintain a constant high sound, and the water supplied to the host is easily resonated using the power supply and the water pump. The feature is that you can find points. In the related art, a large beaker connected to a rubber hose or the like instead of a water pump is filled with water, and the height of the resonance is measured while adjusting the height by hand. Therefore, the height of the column of water filled from the bottom of the host can be easily measured.

기주(1)의 상단부는 개구되어 있으며, 그것을 통하여 발성체로부터 발생한 고음이 전달되며, 하단부는 물펌프로부터 물이 공급되도록 구멍(4)이 형성되어 있다. 발성체(2)는 온-오프(on-off)가능한 전자 킷트의 그것과 연결된 소형 스피커로 구성되며, 상기 스피커로부터 발생된 고음이 기주(1)내로 전달된다.The upper end of the host 1 is opened, through which the high sound generated from the voiced body is transmitted, and the lower end is formed with a hole 4 so that water is supplied from the water pump. The speaker 2 is composed of a small speaker connected to that of an on-off-capable electronic kit, and the high sound generated from the speaker is transferred into the host 1.

진동수 측정 과정을 보면, 발성체에 의하여 고음이 발생하고, 공기주속으로 공급되는 물에 의하여 형성되는 수주가 일정 위치에 도달하면 상기 발성체에 의한 고음의 공명현상이 일어나게 된다. 이때의 수주의 높이를 측정하면 진동수는 용이하게 계산될 수 있다. 즉, 수주의 높이에 따라 파장이 계산되며, V=λ·f의 공식에 의하여 진동수가 계산된다(단, 여기서 V는 음속, λ는 파장, f는 진동수를 나타낸다.).In the frequency measurement process, high sound is generated by the voice, and when the water column formed by the water supplied to the air circumference reaches a predetermined position, resonance of the high sound by the voice occurs. The frequency can be easily calculated by measuring the height of the column at this time. That is, the wavelength is calculated according to the height of the water column, and the frequency is calculated by the formula of V = λ · f (where V is the speed of sound, λ is the wavelength, and f is the frequency).

또한 본 고안 장치는 기주의 상단부에 성형된 ㄱ자형의 관을 이용하여 그속에 있는 물체의 이동구에 의하여 물체의 운동 즉, 수직방향과 수평 방향의 운동 실험도 할 수 있도록 제작되었는데, 기주의 상단부 발성체의 하단에 위치한 차단편(3)에 의하여 'ㄱ'자형의 관속으로 물이 유동 또는 차단하는 것을 조정하게 되어 있으며 물이 관속으로 이동하면 그속에 위치한 부력이 있는 물질로 성형된 물체 이동구가 이동하여 그에 따라 물체의 운동실험이 가능하게 되는 것이다.In addition, the device of the present invention was designed to be able to experiment the movement of the object, that is, the vertical direction and the horizontal direction by the moving tool of the object therein, using the L-shaped tube formed at the upper end of the host. The blocking piece (3) located at the bottom of the vocal material is to control the flow or blocking of water into the '-' shaped tube, and when the water moves into the tube, the object mover is formed of buoyant material located therein. Will move and accordingly the motion experiment of the object will be possible.
