본 고안은 스피커에 관한 것으로서, 보다 상세하게는 마그네트에서 발생하는 자속방향을 스피커구동에 필요한 자속방향과 일치하도록 스피커의 자기회로를 형성하는 스피커에 관한 것이다.The present invention relates to a speaker, and more particularly, to a speaker for forming a magnetic circuit of the speaker so that the magnetic flux direction generated in the magnet coincides with the magnetic flux direction required for speaker driving.
종래 스피커의 자기회로는 제1a도에 도시된 바와 같이 구성되어, 스피커를 구동시킬때 사용되는 마그네트(20)에서 발생하는 자속방향이 제1b도와 같이 스피커 구동시에 필요한 보이스코일(30)의 자속방향과 직각으로 교차하기 때문에 이를 일치시키기 위한 수단으로 상기 마그네트(20)위에 플레이트(10)를 부착하였다.The magnetic circuit of the conventional speaker is configured as shown in FIG. 1A, and the magnetic flux direction generated in the magnet 20 used to drive the speaker is the magnetic flux direction of the voice coil 30 required for driving the speaker as shown in FIG. 1B. Since it intersects at right angles, the plate 10 is attached on the magnet 20 as a means for matching it.
이와같이, 중간매체인 플레이트(10)를 이용하여 마그네트(20)에서 발생하는 자속방향과 보이스코일(30)에서 발생하는 자속방향을 일치하면 자속의 효율이 낮게되고, 또한 플레이트 사용으로 중량이 무거운 문제점이 있었다.As such, when the magnetic flux direction generated in the magnet 20 and the magnetic flux direction generated in the voice coil 30 are matched using the plate 10 which is an intermediate medium, the efficiency of the magnetic flux is low, and the weight is heavy due to the use of the plate. There was this.
따라서, 본 고안은 상기와 같은 제반문제점을 해소하기 위해 안출된 것으로서, 본 고안의 목적은 마그네트에서 발생하는 자속반향을 스피커구동에 필요한 자속방향과 일치하는 자기회로를 가진 스피커를 제공하는데 그 목적을 두고 있다.Therefore, the present invention has been devised to solve the above problems, and an object of the present invention is to provide a speaker having a magnetic circuit that matches the magnetic flux direction required for speaker driving with the magnetic flux reflection occurring in the magnet. I put it.
상기의 목적을 달성하기 위해 본 고안은, 스피커의 진동판을 구동하도록 보빈에 권선된 보이스코일과, 상기 보이스코일이 권선된 보빈을 상하 진동하도록 자력을 발생하는 마그네트와, 상기 마그네트에서 발생한 자속의 방향과 보이스코일에서 발생한 자속의 방향이 일치하도록 마그네트를 지지하는 요크로 구성된 것을 특징으로 한다.In order to achieve the above object, the present invention provides a voice coil wound on a bobbin to drive a diaphragm of a speaker, a magnet generating magnetic force to vibrate the bobbin on which the voice coil is wound, and a direction of magnetic flux generated in the magnet. And a yoke supporting the magnet so that the direction of the magnetic flux generated from the voice coil and the same.
이하, 예시된 도면을 참조하여 본 고안을 더욱 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the illustrated drawings.
제2a도는 본 고안에 따른 스피커의 자기회로 형성을 나타낸 도면이고, 2b도는 자속경로를 나타낸 도면이다.Figure 2a is a view showing the magnetic circuit formation of the speaker according to the present invention, Figure 2b is a view showing a magnetic flux path.
제2a도에서 보이스코일(30)은 스피커의 진동판(도면에 생략되어 있음)을 구동하도록 후술하는 요크(40)의 중심선을 기준으로 이동가능하게 설치된 보빈(60)에 권선되어 있으며, 마그네트(20)는 외주연이 보이스코일(30) 위치까지 절곡된 요크(40)의 절곡단부에 장착되어 있다.In FIG. 2a, the voice coil 30 is wound around a bobbin 60 provided to be movable relative to the center line of the yoke 40 to be described later to drive the diaphragm (not shown in the drawing) of the speaker, and the magnet 20 ) Is attached to the bent end of the yoke 40 whose outer circumference is bent to the position of the voice coil 30.
상기한 바와 같은 자기회로를 가진 스피커는 스피커의 진동판을 구동하는 보이스코일(30)에서 발생하는 자속의 방향과 요크(40)의 절곡단부에 장착된 마그네트(20)에서 발생하는 자속의 방향이 일치하므로 자기회로의 자속경로는 제2b도와 같이 되어 진동판을 원활하게 구동한다.In the speaker having the magnetic circuit as described above, the direction of the magnetic flux generated by the voice coil 30 driving the diaphragm of the speaker coincides with the direction of the magnetic flux generated by the magnet 20 mounted at the bent end of the yoke 40. Therefore, the magnetic flux path of the magnetic circuit is as shown in Fig. 2b to smoothly drive the diaphragm.
즉, 마그네트(20)에서 발생된 자력이 보이스코일(30)에서 발생되는 자력과 직접 접촉하게 되므로 자기회로의 자속효율을 향상시킨다.That is, the magnetic force generated in the magnet 20 is in direct contact with the magnetic force generated in the voice coil 30, thereby improving the magnetic flux efficiency of the magnetic circuit.
상술한 본 고안에 의하면, 마그네트에서 발생되는 자력이 보이스코일에서 발생되는 자력과 직접 접촉되므로 중간매체인 플레이트를 제거할 수 있어 스피커를 소형경량화할 수 있으며, 또한 자속의 효율을 높일 수 있는 장점이 있다.According to the present invention described above, since the magnetic force generated in the magnet is in direct contact with the magnetic force generated in the voice coil, the plate, which is an intermediate medium, can be removed, thereby making the speaker compact and lightweight, and also improving the efficiency of the magnetic flux. have.
