상기한 목적을 달성하기 위하여, 본 발명은 스피커의 진동을 차단하는 전측, 후측 플랜지와, 방진 고무를 일정한 형태로 유지시키도록 내측 원통부와 외측부가 경도가 다르게 성형된 이중 고무에 의하여 해결된다.In order to achieve the above object, the present invention is solved by a front rubber, a rear flange for blocking the vibration of the speaker, and a double rubber molded in the inner cylindrical portion and the outer portion is different in hardness to keep the dust-proof rubber in a constant form.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조하면서 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1, 2에 도시되듯이 방진 고무(9)는 경도가 서로 다른 내측 원통부(14)와 외측부(17)로 성형된다. 내측 원통부(14)는 높은 경도의 고무로 형성되어, 체결 나사(16)의 조립 토크를 모두 받더라도, 내측 원통부(14)의 변형량이 작아 방진고무의 일정형태가 유지된다. 반면, 외측부(17)는 낮은 경도의 고무로 성형되어, 스피커의 진동이 효과적으로 차단된다.As shown in Figs. 1 and 2, the anti-vibration rubber 9 is formed into the inner cylindrical portion 14 and the outer portion 17 having different hardness. The inner cylindrical portion 14 is formed of rubber of high hardness, and even if all the assembly torques of the fastening screw 16 are received, the deformation amount of the inner cylindrical portion 14 is small, so that a constant shape of the anti-vibration rubber is maintained. On the other hand, the outer portion 17 is molded of a low hardness rubber, the vibration of the speaker is effectively blocked.

외측부(17)에는 중간부(11)와 그 양끝단에 위치하는 전측, 후측 플랜지(10, 12), 후측 플랜지부(12)가 더욱 후측으로 연장되어 형성되는 원추부(13)와 내경 확장부(15)로 구성된다. 중간부(11)는 원통형상이고 그 원주면에 방진 고무용 보스(8)와 축보스방식으로 결합된다. 전측 플랜지(10)는 중간부의 전측(도 1에서 좌측)끝부분에 위치하고, 방진 고무(9)가 조립되는 경우에 스냅방식으로 전측 플랜지(10)가 방진 고무용 보스(8)의 구멍에 삽입되고, 조립된 후에는 스피커 어셈블리(2)(도 4 참조)를 지지하여 진동이 모니터에 전달되는 것을 차단한다. 후측 플랜지(12)는 중간부(11)의 후측(도 1에서 우측)의 끝부분에 위치하여, 상기 전측 플랜지(10)와 함께 스피커 어셈블리(2)를 지지하여 진동이 모니터에 전달되는 것을 차단한다. 원추부(13)는 후측 플랜지(12)에서 후측으로 직경이 작아지는 원추형상이고 그 끝부분에서 접하는 체결용 나사(16)의 조립 토크는 내측 원통부(14)에만 가하여지고, 진동을 차단하는 전측, 후측 플랜지(10, 12)에는 영향을 주지 않게 되어, 방진고무의 일정형태가 유지된다. 내경 확장부(15)는 체결용 나사(16)의 외경보다 크게 확장되고 경도가 높은 내측 원통부(14)가 없어, 조립되는 경우에 스냅방식으로 전측 플랜지(10)가 방진 고무용 보스(8)의 구멍에 삽입되는 것을 용이하게 하고, 조립된 후에는 삽입된 조립용 보스(7)(도 2 참조)가 스피커 어셈블리(2)를 지지할 수 있게 된다.The outer portion 17 has a conical portion 13 and an inner diameter expansion portion in which the intermediate portion 11 and the front, rear flanges 10 and 12 and the rear flange portion 12 located at both ends thereof are further extended to the rear side. It consists of 15 pieces. The intermediate portion 11 is cylindrical in shape and coupled to the circumferential surface of the anti-vibration rubber boss 8 in an axial boss manner. The front flange 10 is located at the front end (left in FIG. 1) of the middle portion, and when the anti-vibration rubber 9 is assembled, the front flange 10 is inserted into the hole of the anti-vibration rubber boss 8 in a snap method. After assembly, the speaker assembly 2 (see FIG. 4) is supported to prevent vibration from being transmitted to the monitor. The rear flange 12 is located at the end of the rear side (right side in FIG. 1) of the middle portion 11, and supports the speaker assembly 2 together with the front flange 10 to prevent vibration from being transmitted to the monitor. do. The conical part 13 is a conical shape whose diameter decreases from the rear flange 12 to the rear side, and the assembling torque of the fastening screw 16 contacting at the end thereof is applied only to the inner cylindrical part 14, and the front side which blocks vibration. The rear flanges 10 and 12 are not affected, and a certain form of the anti-vibration rubber is maintained. The inner diameter expansion portion 15 is larger than the outer diameter of the fastening screw 16, and there is no inner cylindrical portion 14 having a high hardness, so that the front flange 10 has a dust-proof rubber boss 8 in a snap manner when assembled. The insertion boss 7 (see FIG. 2) can support the speaker assembly 2 after being assembled.

도 3, 4에는 방진 고무가 조립되어 사용되는 상태를 도시하는 도면이다. 도 4에 도시되듯이 스피커 어셈블리(2)는 스피커(6)와 스피커(6)의 지지대(5)와 스피커 커버(4)로 구성되어 있다. 스피커(6)은 스피커(6)의 지지대(5)에 나사로 먼저 체결되고, 스피커 커버(4)가 스피커의 지지대(5)에 결합된다.3 and 4 are views showing a state in which the anti-vibration rubber is assembled and used. As shown in FIG. 4, the speaker assembly 2 is composed of a speaker 6, a support 5 of the speaker 6, and a speaker cover 4. The speaker 6 is first fastened to the support 5 of the speaker 6 with a screw, and the speaker cover 4 is coupled to the support 5 of the speaker.

스피커 어셈블리(2)는 프런트 커버(1)에서 돌출되는 조립용 보스(7)에 조립된다. 조립하기 위하여, 방진 고무(9)가 먼저 방진 고무용 보스(8)에 스냅인(snap-in)되고, 방진 고무(9)의 내경 확장부(15)에 조립용 보스가 삽입된다. 체결용 나사(16)가 방진고무(9)의 내측 원통부(14) 내로 삽입되어 조립용 보스(7)의 나사부에 체결된다.The speaker assembly 2 is assembled to the assembling boss 7 protruding from the front cover 1. In order to assemble, the anti-vibration rubber 9 is first snap-in to the anti-vibration rubber boss 8, and the assembling boss is inserted into the inner diameter extension 15 of the anti-vibration rubber 9. The fastening screw 16 is inserted into the inner cylindrical portion 14 of the anti-vibration rubber 9 and fastened to the screw portion of the assembling boss 7.

상기한 구성의 본 발명에 따르면, 체결용 나사의 조립토크에 의한 방진 고무의 변형이 적고, 또한 스피커의 진동이 모니터에 전달되는 것을 차단하는 효과가 있다.According to the present invention of the above configuration, there is little deformation of the anti-vibration rubber due to the assembling torque of the fastening screw, and there is an effect of preventing the vibration of the speaker from being transmitted to the monitor.
