*도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

본 고안은 스피커(Speaker)용 플레이트(Plate)구조에 관한 것으로, 특히 음성코일(Voice Coil) 과 대응하는 플레이트의 내면에 다수의 요홈을 형성함으로써, 자속밀도를 균일하게 하고 와전류를 감소시킨 것이다.The present invention relates to a structure of a plate for a speaker, and in particular, by forming a plurality of grooves on an inner surface of a plate corresponding to a voice coil, the magnetic flux density is uniform and the eddy current is reduced.
종래의 스피커는 첨부 도면 제1도에 도시된 바와 같이 요크(1)와 일체로 형성된 플랜지(1a)에 마그네트(2)를 부착하고 그위에 플레이트(3)를 설치한 후 플레이트 내면(3′)과 요크(1)사이에 음성코일(Voice coil)(4)을 설치한 자기회로를 구성하여 음성코일(4)에 전류를 통과시키면, 플레임의 왼손법칙에 의하여 음성코일(4)이 상하로 진동하게 되는데 이때 상기 음성코일(4)과 대응하는 플레이트(3)의 내면(3′)이 평탄하게 형성되었기 때문에 첨부 도면 제2도에 도시된 바와 같이, 자력선은 플레이트(3)의 상,하양단 모서리부분으로 많이 발생하고 중앙부분에는 적게 발생되어서 자속이 불균일하고 와전류가 많이 발생하여 깨끗한 음질을 발생시키지 못하는등 많은 문제점이 있었던 것이 현실정이다.Conventional speakers have a magnet 2 attached to a flange 1a integrally formed with the yoke 1 and a plate 3 installed thereon as shown in FIG. When a current is passed through the voice coil 4 by constructing a magnetic circuit provided with a voice coil 4 between the yoke 1 and the yoke 1, the voice coil 4 vibrates up and down by the left-hand rule of the flame. At this time, since the inner surface (3 ') of the negative coil (4) and the corresponding plate (3) is formed flat, as shown in Figure 2 of the accompanying drawings, the lines of magnetic force are upper and lower ends of the plate (3) It is a reality that many problems occur, such as the occurrence of a lot of corners and less at the center, so that the magnetic flux is uneven and a lot of eddy currents are not generated to generate clean sound quality.
본 고안은 상기한 종래의 제결합을 감안하여 플레이트의 내면에 다수의 요홈을 형성함으로써, 자속의 밀도를 균일하게 하고 와전류를 감소토록 함을 그 주된 목적으로 하는 것으로 이를 첨부된 도면에 제3도에 의거 상세히 설명하면 다음과 같다.The present invention has a main purpose to form a plurality of grooves on the inner surface of the plate in consideration of the above-mentioned conventional debonding, to make the density of the magnetic flux uniform and to reduce the eddy current. According to the description in detail as follows.
플레이트(3)의 내면(3′)과 대향토록 음성코일(4)을 설치하여 구성되는 스피커 자기회로에 있어서, 상기 플레이트(3)의 내면에 다수의 요철(3a)을 형성하여 자속의 밀도를 균일하게 하고 와전류를 감소토록 구성한 것으로서 이를 더욱 상세히 설명하면 요크(1)와 일체로 형성된 플랜지(1a)에 마그네트(2)를 부착하고 그위에는 내면(3′)에 다수의 요철(3a)을 형성한 플레이트(3)를 설치한후 플레이트 내면(3′)과 요크(1) 사이에 음성코일(4)을 설치하여 자속의 밀도를 균일하게 한것으로 미설명 부호5는 자력선이며 6은 자력선(5)이 흐르면서 구성하는 자력선 밀도이다.In a speaker magnetic circuit comprising a voice coil 4 opposed to an inner surface 3 'of a plate 3, a plurality of unevennesses 3a are formed on the inner surface of the plate 3 to increase the magnetic flux density. It is configured to make the eddy current uniform and to explain in more detail. The magnet 2 is attached to the flange 1a integrally formed with the yoke 1, and a plurality of irregularities 3a are formed on the inner surface 3 '. After installing one plate (3), the negative coil (4) is installed between the plate inner surface (3 ') and the yoke (1) to make the density of magnetic flux uniform. 5 is a magnetic line and 6 is a magnetic line (5). This is the magnetic force line density constituting as it flows.
이와 같이 구성된 본 고안은 음성코일(4)에 전류를 통과시키면 자속이 플레이트(3)에서 요크(1)측으로 흐르면서 플레밍의 왼손법칙에 의하여 음성코일(4)이 상하로 움직이게 되는데, 이때 자력선은 첨부 도면 제4도에 도시된 바와 같이 플레이트(3)의 내면(3′)에 형성된 다수의 요철(3a)의 각 모서리들에서 각각 자력선 밀도를 구성하여 요크(1)로 흐르기 때문에 자속은 거의 균일하게 흐르게 되면 와전류는 감소하게 된다.According to the present invention configured as described above, when the current passes through the voice coil 4, the magnetic flux flows from the plate 3 to the yoke 1 side, and the voice coil 4 moves up and down by the Fleming's left hand law. As shown in FIG. 4, the magnetic flux is almost uniform because the magnetic force density is formed at each corner of the plurality of unevennesses 3a formed on the inner surface 3 'of the plate 3 and flows to the yoke 1, respectively. As it flows, the eddy current decreases.
상기한 바와 같이 본 고안은 마그네트에 부착되어 요크로 자력선을 흘리는 플레이트의 내면에 요철을 형성하여 다수의 모서리를 형성함으로써 상기 각 모서리마다 자력선밀도가 구성되어 자력선을 흘려 보내기 때문에 전체적으로 흐르는 자속이 거의 균일할 뿐만아니라 이때 발생되는 와전류를 감소 함으로써 보다 좋은 음질을 재생시킬 수 있는 신규한 고안이다.As described above, the present invention forms a plurality of corners by forming irregularities on the inner surface of the plate to which magnetic lines are flowed into the yoke, and the magnetic flux density is formed at each corner, and thus the magnetic flux flowing is almost uniform. In addition, it is a novel design that can reproduce better sound quality by reducing the eddy current generated at this time.
