본 고안은 음의 진행방향을 상, 하, 좌, 우로 임의 조정할수 있도록 한 스피커의 방향 조정장치에 대한 것이다.The present invention is directed to a device for adjusting the direction of the speaker so that the direction of sound can be arbitrarily adjusted up, down, left, right.
일반적으로 2채널스테레오 시스템에서 음이 전방에 있는 2개의 스피커에서 직접 출력되어 직접음만 듣게 되었다.In general, in a two-channel stereo system, the sound is output directly from the two speakers in front, so that only the direct sound is heard.
또한, 콘서트의 경우 홀의 구조 및 스피커의 위치에 따라 연주를 하더라도 연주는 앞에서 하지만 벽이나 천정에서 반사되는 간접음은 각 방향에서 부터 들리게 된다.In the case of a concert, even if the performance is performed according to the structure of the hall and the position of the speaker, the indirect sound reflected from the wall or ceiling is heard from each direction even though the performance is performed in front of the performance.
따라서 영화관에서는 이러한 방법에 의해 각 방향에서 간접으로 듣게 되므로 입체감을 느끼게 되며, 이에 따라 스피커의 방향이나 위치가 중요시되는데 종래의 경우에는 전방의 스피커들은 직접음을 내도록 하였고, 후방의 스피커들은 좌, 우 및 상, 하 각도를 적정하게 되도록 설치하여 위와같은 효과를 내도록 하였기 때문에 후방 스피커들을 설치하는데 많은 어려움이 있었으며, 또 일단 설치한 다음에는 그 설치된 상태를 필요에 따라 제조정할수 없게 되는 결점이 있었다.Therefore, in a movie theater, this method is used to listen indirectly in each direction, so that the user feels a three-dimensional effect. Accordingly, the direction or position of the speaker is important. In the conventional case, the front speakers make direct sound, and the rear speakers are left and right. And because the upper and lower angles were installed so as to have the above effect, there was a lot of difficulties in installing the rear speakers, and once installed, there was a defect that can not manufacture the installed state as needed.
본 고안은 위와 같은 점들을 해결하기 위해 스피커의 방향을 상, 하 좌, 우로 조정할수 있도록 받침대위에 착설하므로 음의 방향을 임의 조정할수 있게 고안한 것으로 첨부도면에 의거 상술하면 다음과 같다.In order to solve the above points, the present invention is designed on the pedestal so that the direction of the speaker can be adjusted up, down, left, and right so as to arbitrarily adjust the direction of the sound.
상면에 제어핀(3)과 나선이 형성된 결합봉(2)을 돌출한 받침대(1)에 적정길이의 원호상 활지공(5)과 결합공(6)이 뚫어진 회전대(4)를 결합하여 너트(7)로 회전가능하게 고정하고, 이 회전대(4)에는 상면이 원호상의 경사면(9)으로 되고 그 양측에는 지지편(10)이 형성된 지지대(8)를 이 지지대(8)에는 저면이 원호상의 경사면(9a)으로 되고 양측에는 걸림편(12)이 형성된 스피커본체(11)를 결합하여 지지대(8)의 상면일측에 스프링(13)으로 탄발되게 착설한 볼(14)이 본체(11)저면에 일정간격으로 형성된 고정홈(15)에 끼워지게 하여서된 것이다.A nut is formed by joining a swivel (4) with a circular arc-shaped sliding hole (5) and a coupling hole (6) of appropriate length to a pedestal (1) protruding the control pin (3) and a spirally formed coupling rod (2) on the upper surface. (7) rotatably fixed, and on the swivel table 4, the upper surface is the arcuate inclined surface 9, and on both sides thereof, the support 8 is formed with the support piece 10; The main body 11 has a ball 14 mounted on the upper surface side of the support 8 by coupling the speaker body 11 having the inclined surface 9a on the upper surface and the engaging pieces 12 formed on both sides thereof. It is to be fitted into the fixing groove 15 formed at a predetermined interval on the bottom.
미설명 부호 "16"은 회전대에 결합하는 본체를 고전시켜주는 스크류이다.Reference numeral "16" denotes a screw for hardening the main body that is coupled to the swivel.
이와같이된 본 고안은 회전대(4)에 뚫으는 활지공(5)은 그 길이를 원주의 4분의 1정도록 하는 것이 스피커의 좌, 우 방향조정상태로 보아 가장 적합한 것으로서 그 사용상태를 설명하면 다음과 같다.The present invention, as described above, is the most suitable in view of the left and right direction adjustment state of the speaker, so that the active hole 5 drilled on the swivel table 4 is about one quarter of the circumference. As follows.
먼저, 본체(11)의 방향을 좌, 우로 조정할때에는 본체(11)를잡고 좌, 우 필요한 방향으로 회전시켜주면 받침대(1)의 결합봉(2)을 측으로 하여 회전대(4)가 회전되므로 본체(11)의 방향이 바뀌게 되는데 이때 회전 대(4)에 뚫은 활지공(5)에는 받침대(1)상면에 돌출된 제어핀(3)이 끼워져 있고, 또 이활지공(5)의 길이는 원주의 4분의 1정도 길이로 되어 있기 때문에 본체(11)는 활지공(5)과 제어핀(3)에 의해 45°범위내에서 좌, 우 회전되어 방향이 조정되는 것이다.First, when adjusting the direction of the main body 11 to the left and right, holding the main body 11 and rotating in the required direction left and right, the rotating table 4 is rotated with the coupling rod 2 of the pedestal 1 to the side. The direction of the (11) is to be changed at this time, the control pin (3) protruding from the upper surface of the pedestal (1) is fitted in the sliding hole (5) drilled in the rotating table (4), the length of the movable paper (5) Since the body is about one quarter long, the main body 11 is rotated left and right within the range of 45 ° by the sliding hole 5 and the control pin 3 to adjust the direction.
또한 본체(11)의 방향을 상, 하로 조정할때에는 지지대(8)의 상부에 결합시킨 본체(11)를 위해서 눌려주면 제3도 가상선(A)과 같이 본체(11)는 그 저면이 원호상의 경사면(9a)으로되어 있고, 또 지지대(8)의 상면 역시 원호상의 경사면(9)으로 되어 있기 때문에 이들 경사면(9)(9a)들에 의해 본체(11)는 지지대(8)위에서 원할하게 미끄러지면서 하향되어 방향이 상부로 향하게 되며, 반대로 본체(11)의 하부를 밀어주면 본체(11)는 가상선(B)과 같이 되어 방향이 하부로 향하게 되는 것이다.In addition, when adjusting the direction of the main body 11 up and down, it is pressed for the main body 11 coupled to the upper portion of the support (8), as shown in FIG. Since the inclined surface 9a and the upper surface of the support 8 are also arcuate inclined surfaces 9, the main body 11 smoothly slides on the support 8 by these inclined surfaces 9 and 9a. While the downward direction is directed to the upper side, on the contrary, if the lower portion of the main body 11 is pushed, the main body 11 becomes like an imaginary line B, and the direction is directed downward.
이와 같은 방법으로 방향을 상, 하 조정할수 있게되는 것으로 이러한 과정에서 본체(11)의 저면에는 일정간격으로 고정홈(15)이 형성되어 있고 지지대(8)의 상면에는 볼(14)이 스프링(13)으로 탄발되게 착설되어 있기 때문에 본체(1)의 방향을 상, 하로 조정하게 되면 볼(14)이 고정홈(15)에 끼워져 본체(11)를 지지하여 주므로 조정상태가 임의로 변경되지 않게 되며, 또 지지대(8)의 상면 양측에 형성된 지지편(10)에, 본체(11)의 저면 양측에 형성한 걸림편(12)이 결합되므로, 상, 하 또는 좌, 우 조정시 본체(11)가 유동되지 않게 된다.In this way, the direction can be adjusted up and down. In this process, the bottom of the main body 11 has a fixed groove 15 formed at a predetermined interval, and the ball 14 on the top surface of the support 8 has a spring ( 13) because the ball is installed in the ups and downs, and the direction of the main body 1 is adjusted up and down, the ball 14 is inserted into the fixing groove 15 to support the main body 11 so that the adjustment state is not changed arbitrarily. In addition, since the engaging pieces 12 formed on both sides of the bottom surface of the main body 11 are coupled to the supporting pieces 10 formed on both sides of the upper surface of the support 8, the main body 11 when adjusting the upper, lower, left, or right sides. Will not flow.
이와 같이 본고안은 스피커 본체의 방향을 간편용이하게 상, 하 좌, 우로 조정할수 있기 때문에 스피커를 설치하는데 어려움이 없으며, 또 설치후에도 방향을 임의로 조정할수 있게 되는 등 매우 실용적인 고안이다.In this way, since the direction of the main body of the speaker can be easily adjusted up, down, left, and right, there is no difficulty in installing the speaker, and the direction can be arbitrarily adjusted even after installation.
