본 고안은 음향기기의 스피커에서 발성하는 음향 방향 조정 장치에 관한 것으로 반원형의 음 안내편을 일렬로 다수개 배설한 음향 방향 조정장치를 스피커 케이스 전면에 설치하여 스피커에서 발성하는 음향 방향을 임의로 조절할 수 있도록 한 스피커 음향방향 조정장치에 관한 것이다.The present invention relates to an acoustic direction adjusting device that is produced by a speaker of an acoustic device. The acoustic direction adjusting device having a plurality of semicircular sound guide pieces arranged in a line can be installed on the front of the speaker case to arbitrarily adjust the acoustic direction of the speaker. And a speaker acoustic direction adjusting device.
종래에는 스피커에서 발성하는 음향방향을 조정할시에는 스피커가 부착된 스피커 케이스를 손으로 요구되는 방향으로 향하게 위치시켜서 음향 효과를 얻을 수 있도록 하였으므로 스피커 케이스를 높은 곳에 고정하였을시에는 스피커의 음향 방향을 자유로히 맞출수 없었다.Conventionally, when adjusting the sound direction uttered by the speaker, the speaker case with the speaker is placed in the direction required by the hand to obtain a sound effect. When the speaker case is fixed at a high place, the speaker's sound direction is freely adjusted. I couldn't hit it.
본 고안은 이와같은 점을 감안하여 스피커케이스 전면에 음향 방향을 조정할 수 있는 음향 안내판을 설치하여 음향 안내판의 회전 시킴에 따라서 음향 방향을 임의로 조정할 수 있게 하고 음향의 확산 효과를 얻을 수 있도록 한 것이다.The present invention is to provide a sound guide plate that can adjust the direction of the sound in front of the speaker case in view of the above point so that the sound direction can be arbitrarily adjusted by the rotation of the sound guide plate to obtain a sound diffusion effect.
본 고안의 구성과 작용효과를 도면에 의하여 설명하면 다음과 같다.Referring to the configuration and effect of the present invention by the drawings as follows.
제1도, 제2도를 참조하여 본 고안의 구성을 설명하면 음향방향 조정기 케이스(1)내부 상하면에 뚫어진 구멍(2)에 상하축(3, 3')으로 축지된 다수개의 반원통형 안내편(4)의 상축 축(3)에 기어(5)가 형성되어 다수개의 기어(5)가 중간기어(5')를 통하여 맞물리게 하고 종단에 위치된 기어(5)에는 조정기어(6)가 맞물리되 조정기어의 축(7)은 케이스 벽체(8)내면에 형성된 돌출부(9)의 구멍에 축지되어 벽체(8)외면에 조정기어(6)일부가 돌출되게 한 것이다. 미설명 부호 10 : 스피커 케이스, 11 : 결합나사못이다.Referring to FIGS. 1 and 2, the structure of the present invention will be described. A plurality of semi-cylindrical guide pieces axially supported by upper and lower shafts 3 and 3 'in the holes 2 formed in the upper and lower surfaces of the acoustic direction adjuster case 1 will be described. A gear 5 is formed on the upper shaft 3 of (4) so that a plurality of gears 5 are engaged through the intermediate gear 5 'and the gear 5 positioned at the end is fitted with the adjusting gear 6. Physically, the shaft 7 of the adjusting gear is held in the hole of the protrusion 9 formed on the inner surface of the case wall 8 so that the adjusting gear 6 is protruded on the outer surface of the wall 8. Unmarked 10: Speaker case, 11: Combination screw.
이와같이 구성된 본 고안의 작용효과를 설명하면 제2도와 같이 안내판(4)과 상하축(3, 3'), 기어(5)는 일체로 형성되고 다수개의기어(5)들은 중간기어(5')를 통하여 서로 맞물려 있으며, 우측 종단기어(5)는 조정기어(6)와 맞물려 있다. 제2도와 같이 본 고안의 음향방향조정장치를 스피커케이스 전면에 나사못(11)으로 결합하면 스피커에서 발생하는 음향을 스피커케이스(10) 저면과 음향방향조정기 케이스(1) 내부를 통하여 소리가 나오게 되어있다.Referring to the operation and effect of the present invention configured as described above, the guide plate 4, the upper and lower shafts (3, 3 '), the gear (5) is integrally formed as shown in Figure 2 and the plurality of gears (5) is an intermediate gear (5'). Are engaged with each other, and the right end gear 5 is engaged with the adjusting gear 6. As shown in FIG. 2, when the acoustic direction adjusting device of the present invention is combined with the screw 11 on the front of the speaker case, the sound generated from the speaker is output through the bottom of the speaker case 10 and the inside of the acoustic direction adjuster case 1. have.
음향방향을 조정할시에는 외부에 돌출된 조정기어(6)를 손으로 돌리면 각 기어(5)들도 따라서 회전하게 되는데 스피커에서 발성된 음향은 반원통형 안내편(4)이 중첩된 사이를 지나 외부로 발산된다.When adjusting the acoustic direction, turn the gear (6) protruding from the outside by hand to rotate the gears (5). The sound produced by the speaker passes through the overlap between the semi-cylindrical guide pieces (4). Is divergent.
이 때 반원통형 안내편(4)의 내면 곡선부를 따라서 진행하는 음파는 좌우측으로 완전히 분리되어서 발산되고 동시에 중첩된 반원통형(4) 사이에 직선공간을 따라서 진행되는 음파는 그 방향으로 진행되어 청취자는 결국 서라운드나 와이드의 효과를 얻을 수 있는 것이다.At this time, the sound waves propagating along the inner curved portion of the semi-cylindrical guide piece 4 are completely separated from the left and right sides, and at the same time, the sound waves propagating along the linear space between the overlapping semi-cylindrical shapes 4 proceed in that direction. After all, you can get surround or wide effects.
이것은 음파의 전달 방향은 음원의 중심으로 해서 동심원상으로 퍼져나가나 스피커와 같이 지향성이 있는 음원은 그 지향 방향으로 음이 퍼져나가기 때문에 본원 고안에서 중첩된 반원통형안내편(4)은 스테레오 효과를 더욱 확장하는 와이드 또는 서라운드 효과를 얻을 수 있게 한다.This is because the direction of sound wave propagates in a concentric circle as the center of the sound source, but a directional sound source such as a speaker spreads the sound in its direction, so the semi-cylindrical guide piece 4 superimposed in the present invention has a stereo effect. Allows you to achieve wide or surround effects that extend.
이상에서 설명된 바와같이 본 고안에 의하면 간단한 구성으로 스피커의 방향을 이동시키지 않고도 서라운드 효과 또는 와이드 효과를 얻을 수 있어 특히 실내에 다른 물건들 예를 장농 등과 같은 음파 진행에 방해를 주는 물건이 있을 때 매우 유용한 것이다.As described above, according to the present invention, it is possible to obtain a surround effect or a wide effect without shifting the direction of the speaker with a simple configuration, especially when there are objects in the room that interfere with sound wave progression such as jangnon. It is very useful.
