본 고안은 스테레오(Stereo) 음향을 방출하는 기능을 가진 TV에 설치되는 음향 반향 장치(Reflecting Apparatus for Sound Direction)에 관한 것이다.The present invention relates to a Reflecting Apparatus for Sound Direction installed in a TV having a function of emitting stereo sound.
본 고안에서 음향 반향 장치라 함은 TV본체의 좌우 양측벽에 설치하고 그 설치된 스피커로부터 발해지는 음향이 TV본체의 정면을 향하도록 하는 장치를 말한다.In the present invention, the acoustic echo device refers to a device which is installed on both left and right side walls of the TV main body and directs sound emitted from the installed speaker to the front of the TV main body.
종래의 음향 반향 장치를 보면, 스피커를 TV본체의 양측면에 각각 고정 설치하고, 측방에 반사판을 설치하여 음향의 방향을 전방으로 유도 전환시키도록 하였으나, 이 장치를 사용하는 경우에는 반사판에 의한 단순한 반사음향을 이용하기 때문에 스피커에서 발해진 음이 청취자의 귀에 까지 정확하게 전달하지 못하는 결점이 있었다.In the conventional acoustic echo device, the speaker is fixedly installed on both sides of the TV body, and the reflection plate is installed on the side to induce the direction of the sound to be directed forward. Because of the use of sound, there was a drawback that the sound produced by the speakers could not be accurately delivered to the listener's ears.
따라서, 본 고안은 종래의 위와같은 결점을 해결하기 위하여 측면 내측에 일정 각도로 스피커를 부착하였으며 선단의 축돌기를 중심으로 회동하여 본체의 측벽에 형성한 출립공을 통해 내부로 출입자재 하면서 상측 안내 브라켓트의 가이드 레일 및 위치 설정홈과 접촉하는 각도 조정핀에 의해 개방각도를 조절하도록 하는 음향 반향 장치를 제공한 것으로서, 이를 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Therefore, the present invention is attached to the speaker at a predetermined angle inside the side to solve the above drawbacks of the prior art and rotated around the axle of the tip to guide the upper side while going in and out inside through the standing hole formed on the side wall of the main body. It provides an acoustic echo device to adjust the opening angle by the angle adjusting pin in contact with the guide rail and the positioning groove of the bracket, which will be described in detail with reference to the accompanying drawings.
즉, TV몸체(1)의 양측에 설치되는 음향 반향 장치를 구성함에 있어서, 원호형 후면(41)와 말단부에 이탈 방지턱(42)을 가지는 부채꼴 단면 형태의 회동체(4)를 형성하면서 그 평면과 저면 선단부 상에 각기 축돌기(44)(45)를 형성하였으며, 평면(47) 후단부 일측의 오목홈(43)내에는 상부에 반구형 접촉부(61)와 하부에 탄성 걸림턱(62)를 가지는 각도 조절핀(6)을 스프링(7)으로 탄동 설치하여 일정 높이만큼 상향 돌출 되도록 하였고, 우측면 내측에 형성한 오목부(46) 내에는 도면 제2도에서와 같이 측면과 일정각도(α)를 유지하도록 공지의 스피커(5)를 고정 설치 하므로서, 회동체(4)가 최대로 돌출되었을때에는 스피커(5)가 TV화면의 투사 방향과 평행을 이룰 수 있도록 하였다.That is, in constructing the acoustic echo devices provided on both sides of the TV body 1, the flat surface is formed while the rotating body 4 having a fan-shaped cross section having an arc-shaped rear face 41 and a disengagement stopper 42 at its distal end. And axles 44 and 45 were formed on the front and bottom ends, respectively, and in the concave groove 43 on one side of the rear end of the plane 47, a hemispherical contact portion 61 at the top and an elastic locking jaw 62 at the bottom were formed. Branch angle adjustment pin (6) with a spring (7) to be installed so as to protrude upward by a predetermined height, inside the recess 46 formed on the inside of the right side, as shown in Figure 2 the side and a constant angle (α) By fixing the known speaker 5 so as to maintain the, when the rotating body 4 protruded to the maximum, the speaker 5 was able to be parallel to the projection direction of the TV screen.
또한, TV몸체(1)의 측벽(11)에는 상기 회동체(4)의 높이와 폭에 비례하는 길이와 폭을 가지는 출입공(12)을 형성하면서, 출입공(12)의 상부와 하부 내측으로는 선단부에 각기 회동체(4)의 상하측 축돌기(44)(45) 삽입용 축공(21)(31)을 가지는 일정 길이의 안내 브라켓트(2)(3)를 설치 하였으며, 상측 안내 브라켓트(2)의 저면 후단부의 각도 조정핀(6) 대향 부위에는 도면 제3도에서와 같이 수개의 위치 설정홈(22A, B, C)을 가지는 원호형 가이드 레일(23)을 형성하므로서, 최선단의 위치 설정홈(22C)에 각도 조정핀(6)이 위치하면 회동체(4)는 출입공(12)에서 최대로 돌출된 위치에 오도록 하였으며, 출입공(12) 상부에는 손가락 삽입공(13)을 절개 형성 하여서 된 것으로서, 도면중 미설명 부호 8은 스피커 보호망이다.In addition, the side wall 11 of the TV body 1 is formed with an entrance hole 12 having a length and width proportional to the height and width of the rotating body 4, the upper and lower inner side of the entrance hole 12 The guide brackets (2) and (3) of predetermined lengths having shaft holes (21) and (31) for inserting the upper and lower shaft protrusions (44) and (45) of the rotating body (4), respectively, were installed at the distal end. In the opposite side of the angle adjustment pin 6 of the bottom rear part of (2), as shown in FIG. 3, the arc-shaped guide rail 23 which has several positioning grooves 22A, B, and C is formed, When the angle adjusting pin 6 is positioned in the positioning groove 22C of the pivoting body 4, the entrance body 12 is positioned at the maximum protruding position from the entrance hole 12, and the finger insertion hole 13 is placed above the entrance hole 12. In the figure, reference numeral 8 denotes a speaker protection net.
이상과 같이 구성된 본 고안의 작동 상태를 보면 다음과 같다.Looking at the operating state of the present invention configured as described above are as follows.
회동체(4)는 선단의 축돌기(44)(45)가 상하측 안내 브라켓트(2)(3)의 축공(21)(31)이 삽입 결합 되므로서, 이를 중심으로 회동자재 하면서 출입공(12) 내외부로 돌출 삽입 동작하는데, 이때, 회동체(4) 상면 후단부 일측에 탄동 설치된 각도 조정핀(6) 상부의 반구형 접촉부(61)가 상기 가이드레일(23)에 안내 되므로서, 정확하게 회전운동하는데, 도면 제4a도에서와 같이 접촉부(61)가 가이드레일(23) 면과 접하는 상태에서는 회동체(4)에 약간의 외력을 가해주면 쉽게 좌우로 회전하지만, (b)에서와 같이 위치 설정홈(22)내에 삽입되어 있을 때에는 상당한 외력을 가하기 전에는 움직이지 않게 되어 회동체(4)의 위치가 고정되는 것인데, 그 형성 위치는 회동체(4)의 완전 삽입위치, 중간 삽입위치, 최대 돌출위치에 각기 3개를 형성해 주면 이상적이고, 그에 따라 스피커(5)의 지향 각도도 A, B, C위치로 가변되어 보다 자연적인 음향 청취를 가능케 함과 동시, 회동체(4)의 이탈 방지를 위하여 원호형 후면 말단부에 이탈방지턱(42)을 형성하였으며(도면 제2도 가성선 참조), 필요에 따라서는 상측 안내 브라켓트(2) 저면에 회동체(4)의 회전각도 제어용 스텁포더 형성하도록 한다.The rotating body 4 is the shaft projections 44, 45 of the tip is coupled to the shaft hole 21, 31 of the upper and lower guide brackets (2) and (3) is inserted and coupled, so that the rotational material around the entrance hole ( 12) Protruding insertion operation into the inside and outside, at this time, the hemispherical contact portion 61 of the upper part of the angle adjusting pin 6 installed on one side of the rear end of the upper surface of the rotating body 4 is guided to the guide rail 23, thereby accurately rotating. In the state in which the contact portion 61 is in contact with the surface of the guide rail 23 as shown in FIG. 4A, when a slight external force is applied to the pivoting body 4, it rotates easily to the left and right, but as shown in (b). When it is inserted into the set groove 22, it does not move until a significant external force is applied, and the position of the rotating body 4 is fixed. The forming position is the complete insertion position, the intermediate insertion position, the maximum position of the rotating body 4. Ideally, three at the protruding position should be provided, thus providing the speaker (5) Directional angles are also changed to A, B, and C positions to allow more natural sound listening, and at the same time, a departure prevention jaw 42 is formed at the rear end of the arc to prevent the departure of the pivot 4 (Fig. 2). If necessary, a stub feeder for controlling the rotation angle of the rotational body 4 is formed on the bottom surface of the upper guide bracket 2 as necessary.
그리고, 출입공(12)상의 손가락 삽입공(13)은 완전 삽입된 회동체(4)를 꺼낼 때 이를 통해 손가락을 삽입하여, 회동체(4)의 상면을 압박하면서 측방 인출해 낼 수 있도록 하는 것이다.And, the finger insertion hole 13 on the entrance hole 12 to insert the finger through this when the fully inserted rotating body (4), so as to push out the upper side of the rotating body (4) to draw out sideways will be.
이상과 같이 구성되고 작동되는 본 고안은, TV몸체(1)의 양측벽(11)에 스피커(5)를 일정 각도로 설치하고, 상측 안내 브라켓트(2)의 가이드레일(23)과 위치 설정홈(22)에 의해 안내되어 출입 회동 자재하는 회동체(4)를 구비하므로서, 청취자가 스피커의 각도를 원하는 각도로 변환시키면서 보다 생생하고 자연적인 음향을 청취함과 동시, 종래의 스피커 고정 붙박이 방식에서 발생하던 측방 돌출물을 배제하고 TV청취를 않을 시는 회동체(4)를 측벽면과 일치 되도록 삽입해 넣으므로서 몸체의 외관이 단순 미려해 지는등의 특출한 효과가 있는 것이다.The present invention constructed and operated as described above, the speaker 5 is installed on both side walls 11 of the TV body 1 at a predetermined angle, the guide rail 23 and the positioning groove of the upper guide bracket (2) By having the rotating body 4 guided and rotated by the 22 to allow the listener to change the angle of the speaker to a desired angle while listening to more vivid and natural sound, the conventional speaker fixing built-in method When the TV is not listened to without the side protrusions that have occurred, there is an extraordinary effect such that the appearance of the body becomes simple and beautiful by inserting the rotating body 4 to match the side wall surface.
