* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 평면진동판 2 : 더스트캡1: flat vibration plate 2: dust cap
본 고안은 장방형 평면 스피커에 관한 것으로, 특히 평면진동판의 일부를 일정한 형태로 절개한 다음 더스트캡을 상기 절개부위에 부착시킴으로써 주파수 대역의 고역부를 개선하도록 된 장방형 평면 스피커에 관한 것이다.The present invention relates to a rectangular flat speaker, and more particularly, to a rectangular flat speaker designed to improve a high-frequency portion of a frequency band by cutting a portion of a flat vibration plate into a predetermined shape and then attaching a dust cap to the cut portion.
장방형 평면 스피커의 동작원리를 알아보면 보이스코일의 상하수직운동을 코온지에 전달하므로써 엣지에 연결된 평면진동판을 진동시키고 상기 진동에 의해 진동판과 공기와의 입력변화로 인한 음을 발생하게 되는데, 상기 평면진동판에 있어서 종래와 같이 평탄한 면으로 형성하여 사용하다 보면 높은 주파수에서 보이스코일의 상하수직 운동속도가 급격히 증가할 경우 진동판의 중앙부위와 모서리부위간의 움직임이 일치되지 않는 현상이 일어나 출력음압 레벨에 요철(凸)이 나타나는 분할진동을 발생시키게 되고 상기 분할진동에 의해 고음에서 지향특성이 크게 열화되는 주파수감쇠현상이 일어나게 되는 문제점이 있었다.When the operation principle of the rectangular flat speaker is transmitted, the vertical vibration of the voice coil is transmitted to the nose paper, thereby vibrating the plane vibrating plate connected to the edge, and the vibration generates sound due to the input change between the diaphragm and the air. In the diaphragm, when the flat surface is formed as in the prior art, when the vertical and vertical movement speed of the voice coil is rapidly increased at high frequency, the movement between the center part and the corner part of the diaphragm is inconsistent and the output sound pressure level is uneven. There was a problem in that a frequency division phenomenon occurs in which the vibration generated by (i) is generated and the directivity is greatly deteriorated in the treble due to the division vibration.
본 고안은 상기 문제점을 해결하기 위하여 평면진동판의 일부를 일정한 형태로 절개한 다음 가볍고 탄력이 있는 재질로 된 더스트캡을 상기 절개부위에 부착시킨 장방형 평면 스피커을 제공하는데 그 목적이 있다.The present invention aims to provide a rectangular flat speaker in which a portion of the flat vibrating plate is cut in a predetermined form and then a dust cap made of a light and elastic material is attached to the cutout portion.
이하 본 고안의 구성 및 작용, 효과를 예시된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the configuration, operation, and effects of the present invention will be described in detail with reference to the illustrated drawings.
본 고안은 자계회로부와 진동부로 구성되되 상기 진동부의 평면진동판(1)에는 하나 또는 다수개의 절개부를 형성시키며 상기 절개부에 더스트캡(2)을 부착시킨 구조로 되어 있다.The present invention is composed of a magnetic circuit portion and a vibrating portion, but one or a plurality of cutouts are formed in the flat vibrating plate (1) of the vibrating portion, and has a structure in which a dust cap (2) is attached to the cutout portion.
미설명부호 3은 폴, 4는 마그네틱, 5는 보이스코일, 6은 코온지, 7은 엣지이다.Unmarked 3 is pole, 4 is magnetic, 5 is voice coil, 6 is Coon, 7 is edge.
상기와 같은 구조를 가지는 본 고안은 평면진동판에 더스트캡을 부착하여 고역을 개선한 것이다.The present invention having the structure as described above is to improve the high range by attaching a dust cap to the flat vibration plate.
본 고안의 실시예를 나타낸 제1도는 폴(3)과 마그네틱(4)으로 형성된 자계회로부와 보이스코일(5)과 코온지(6), 엣지(7) 및 평면진동판(1)으로 형성된 진동부로 구성시킴으로써, 상기 폴(3)과 마그네틱(4)에 의해 형성된 자계 회로내에 삽입된 보이스코일(5)에 전류를 흘려보내게 되면 상기 신호전류에 비례하여 보이스코일(5)의 상하수직 운동이 일어나며, 이는 곧 코온지(6)를 통해 평면진동판(1)을 진동시켜 음을 발생하도록 하는데, 상기 평면진동판(1)에는 하나 또는 다수의 절개부를 형성시켜 더스트캡(2)을 부착시킴으로써 높은 주파수대에서 종래와 같이 중앙부위 진동과 모서리부위 진동과의 불균형을 방지할 수 있으며, 분할공진이 적고 찌그러짐이 적은 지향특성을 가질 수 있다.1 shows an embodiment of the present invention is a magnetic circuit portion formed of the pole (3) and the magnetic (4) and the vibration portion formed of the voice coil (5), the coon (6), the edge (7) and the flat vibration plate (1) In this configuration, when a current flows through the voice coil 5 inserted into the magnetic circuit formed by the pole 3 and the magnetic 4, vertical and vertical motion of the voice coil 5 occurs in proportion to the signal current. This causes the sound of vibration by vibrating the planar vibrating plate 1 through the coronage 6, which forms one or a plurality of cutouts in the planar vibrating plate 1 and attaches the dust cap 2 at a high frequency band. As in the prior art, it is possible to prevent the imbalance between the vibration of the center portion and the vibration of the edge portion, and may have a directivity characteristic of less division resonance and less distortion.
상기와 같은 본 고안은 평면진동판의 평탄한 면에 하나 또는 다수의 절개부를 형성시키고 가볍고 탄력이 있는 재질로 된 더스트캡을 부착시킴으로써 고음에서 분할진동과 찌그러짐이 발생하는 현상을 방지할 수 있으며 주파수대의 고역을 개선시킬 수 있는 효과가 있다.The present invention as described above, by forming one or a plurality of incisions on the flat surface of the flat vibration plate and by attaching a dust cap made of a light and elastic material, it is possible to prevent the phenomenon of split vibration and distortion at high frequencies and high frequencies There is an effect that can improve.
