본 고안은 스피커에 관한 것으로 스피커의 에지에 하향댐퍼부를 형성하여 진동판지지와 댐퍼기능을 갖도록하여 또한, 후레임의 중앙부를 절곡 형성하여 자기회로 구성과 자체방자(自體放磁)기능을 갖도록한 것이다.The present invention relates to a speaker, which forms a downward damper at the edge of the speaker to have a diaphragm support and a damper function, and to form a bent portion at the center of the frame to have a magnetic circuit configuration and a self shielding function. .
종래의 스피커에 있어서는 일반적으로 제2도에 도시한 바와 같이, 자기회로를 형성하는 어퍼플레이트(100)의 상측과 내측으로 후레임(101)과 보이스코일(102)의 권최된 보빈(103)을 내설하고 후레임(101)에는 에지(104)로써 진동판(105)을 고착하며 상기 보빈(103)과 후레임(101)간에는 댐퍼(106)를 설치한다. 또한 상기 어퍼플레이트(100) 하측에는 메인마그네트(107)와 버텀플레이트(108)를 설치하고 버텀플레이트(108)하측에는 서브마그네트(109)를 설치하되 이를 지지하기 위한 실드케이스(110)를 설치하여서 된 구성이다.In the conventional speaker, as shown in FIG. 2, the bobbin 103 of the frame 101 and the voice coil 102 is installed above and inside the upper plate 100 forming the magnetic circuit. The diaphragm 105 is fixed to the frame 101 by the edge 104, and a damper 106 is installed between the bobbin 103 and the frame 101. In addition, the main magnet 107 and the bottom plate 108 is installed below the upper plate 100, and the sub magnet 109 is installed below the bottom plate 108, and a shield case 110 is installed to support the bottom plate 108. Configuration.
이와 같이 구성된 종래의 고안은, 스피커 구동시 급격한 출력이나 또는 충격등에 의하여 보빈(103)이 터치되면 양호한 음이 발생되지 아니하여 이를 방지하기 위한 댐퍼(106)를 구성하여야 했다. 또한 자기회로를 구성하기 위해서는 버텀플레이트(108)가 필요하며, 스피커의 방자를 위해서는 별도의 서브마그네트(109)와 이를 지지하기 위한 실드케이스(110)를 구성 설치하여야 했다. 따라서, 이에 따른 구성이 복잡하고 또한 부품수가 많아 많은 작업공정과 원가상승등에 의한 작업공수가 좋지 못한 결점이 있었다.According to the conventional design configured as described above, when the bobbin 103 is touched by a sudden output or impact when driving a speaker, a good sound is not generated and a damper 106 is required to prevent this. In addition, a bottom plate 108 is required to configure a magnetic circuit, and a separate sub-magnet 109 and a shield case 110 for supporting the same have to be installed to install a speaker. Therefore, there is a drawback in that the construction is complicated and the number of parts is large.
따라서 본 고안은 상기와 같이 종래의 문제점을 해결하기 위하여 안출된 것으로 진동판을 고정설치하는 에지에 하향댐퍼부를 형성하여 상부는 진동판을 지지고정하는 역할을 하고 하부는 댐퍼역할을 하며, 후레임의 중앙을 절곡하여 폴피스를 형성함으로써 자기회로 구성과 자체 방자 역할을 할수 있도록 하여서 된 것으로 이하 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the conventional problems as described above to form a downward damper on the edge for fixing the diaphragm, the upper part serves to support the diaphragm and the lower part acts as a damper, bending the center of the frame By forming the pole piece to act as a magnetic circuit configuration and self-protection will be described in detail by the accompanying drawings as follows.
어퍼플레이트(1)의 하측부와 중앙부는 메인마그네트(2)와 보이스코일(3)이 권취된 보빈(4)를 각각 설치한 스피커에 있어서, 상기 메인마그네트(2) 하면에는 중앙부를 절곡하여 폴피스(5)를 형성한 후레임(6)을 고정설치하고 후레임(6)의 선단부에는 에지(7)를 설치하되 이의 내측 하향으로 하향댐퍼부(8)를 형성하며, 상기 에지(7) 상부에는 진동판(9)을 고정설치토록 하여서된 구성이다.The lower side and the center portion of the upper plate 1 are provided with a main magnet 2 and a bobbin 4 wound around the voice coil 3, respectively. The bottom surface of the main magnet 2 is bent to form a pole The frame (6) formed frame (6) is fixed and installed, the edge of the frame (6) is provided with an edge (7), but the downward damper portion (8) is formed in the inner downward direction of the upper edge (7) The diaphragm 9 is fixedly installed.
이와 같이 구성된 본 고안의 작용효과를 설명한다.It describes the effect of the present invention configured as described above.
즉, 본 고안은 후레임(6)의 중앙부를 절곡하여 폴피스(5)를 형성함으로써 종래의 버텀플레이트(108)와 같이 자기회로를 구성하며, 또한 후레임(6)의 중앙부를 절곡하여 형성한 폴피스(5)가 중공부를 이루고 있으므로 중공부의 내측과 외측으로 이중자력이 발생되어 자체 방자역할을 함으로써 종래와 같은 방자역할을 하는 서브 마그네트(109)가 필요치 않음은 물론 후레임(6) 자체가 종래의 버텀플레이트(109)와 실드케이스(110)역할을 할 수 있도록 그 기능을 수행하는 것이다. 그리고 본 고안은 후레임(6) 선단부에 설치된 에지(7)의 내측 하향으로 하향 댐퍼부(8)를 형성함으로써 에지(7)의 상부에 진동판(9)이 고정설치될수 있도록 하고 하향댐퍼부(8)는 스피커의 급격한 출력이나 충격을 흡수하여 완충작용을 가짐으로써 보빈(4)이 지그러지거나 손상됨을 방지하는 것이다.In other words, the present invention forms the magnetic circuit by bending the central portion of the frame 6 to form the pole piece 5, and the pole formed by bending the central portion of the frame 6 and forming the magnetic circuit. Since the piece 5 forms a hollow part, a dual magnetic force is generated inside and outside the hollow part, thereby acting as a self-magnetic shield, so that the sub-magnet 109 that acts as a conventional magnetic shield does not need to be used. The bottom plate 109 and the shield case 110 is to perform its function to serve. In addition, the present invention forms a downward damper portion 8 inwardly downward of the edge 7 provided at the front end of the frame 6 so that the diaphragm 9 can be fixedly installed on the upper portion of the edge 7 and the downward damper portion 8 is provided. ) Is to absorb the sudden output or impact of the speaker to have a cushioning action to prevent the bobbin 4 from being distorted or damaged.
이와 같이 본 고안은 종래의 버텀플레이트(108), 서브마그네트(109), 실드케이스(110)및 댐퍼(106)를 별도로 구성함이 없이 중앙부가 절고된 후레임(6)을 구성하여 자기회로 구성과 자체방자 역할을 하고, 에지(7)에 하향댐퍼부(8)를 형성함으로써 진동판(9)을 고정지지 함은 물론 댐퍼역할을 갖는 기능을 갖게 하면서도, 구성을 간단히 하여 부품수를 줄임으로써 많은 작업공정을 줄이고 또한 원가 상승등을 방지하여 작업수를 좋게 하는 특징을 제공하는 것이다.As such, the present invention does not constitute the conventional bottom plate 108, the sub magnet 109, the shield case 110, and the damper 106. By acting as a self-protection and forming a downward damper portion 8 at the edge 7, it not only fixes the diaphragm 9 but also has a function as a damper, while simplifying the construction to reduce the number of parts, a lot of work It is to provide a feature that improves the number of operations by reducing the process and preventing cost increase.
