본 고안은 다이나믹형 진동소자를 이용한 필름스피커에 관한 것으로, 특히 4각형상의 필름진동판을 아치형으로 형성시켜 그 양측변에 다수의 다이나믹형 진동소자를 설치해 놓음으로서 음향재생효율을 더욱 높여 줄수 있도록 된 다이나믹형 필름스피커에 관한 것이다.The present invention relates to a film speaker using a dynamic vibrating element, and in particular, a quadrangular film vibrating plate is formed in an arch shape, and a plurality of dynamic vibrating elements are installed on both sides thereof to increase the dynamic reproduction efficiency. It relates to a type film speaker.
일반적으로 스피커는 전류신호를 음성신호로 재생시켜 주도록 된 장치로서, 특히 필름스피커는 진동음을 발하는 필름진동판이 아치형상으로 되어있어 발생음이 방사상으로 고르게 발산될 뿐만 아니라, 전면필름이 투명하고 슬립형이기 때문에 장식적인 효과도 매우 큰 것으로 그 이용가치가 높다.In general, a speaker is a device that reproduces a current signal as a voice signal. Especially, a film speaker has an arcuate shape of a film vibration plate that emits vibration sound, and the sound generated is radiated evenly in a radial manner. Because of the decorative effect is also very large, its value is high.
이러한 필름 스피커를 구동시키는 진동소자로서 종래에는 압전형 진동소자를 사용해왔는데, 이 압전형 진동소자는 그 구조가 간단하고 제작이 용이하다는 장점을 가지고 있는 반면, 압전소자의 진동특성상 고유의 주파수, 즉 고역의 주파수에 대해서만 진동효율이 높게 나타날 뿐 음성재생대역이 극히 한정되어 있었으며, 압전소자 자체의 임피던스가 매우 크기 때문에 필름스피커에 이용될 경우에도 그 음압출력특성이 매우 낮게 나타나게 된다는 문제점이 있었다.Conventionally, a piezoelectric vibrating element has been used as a vibrating element for driving the film speaker. While the piezoelectric vibrating element has an advantage that the structure is simple and easy to manufacture, the vibration characteristic of the piezoelectric element has a unique frequency, namely There was a problem that the sound reproducing band was extremely limited only in the high frequency frequency only, and the sound pressure output characteristic was very low even when used in a film speaker because the impedance of the piezoelectric element itself was very large.
이에 본 고안은 상기와 같은 종래의 압전형 필름스피커의 문제점을 개선시켜 주기 위해 고안된 것으로서, 압전형 진동소자 대신 다이나믹형 진동소자를 사용하되 자기회로내에 설치된 보이스 코일상에 캡을 부착시켜 아치형상필름 진동판의 양측변에 접착되도록 함으로써, 폭넓은 대역에 걸쳐 양호한 음성신호를 충실히 재생시켜줄 수 있도록된 다이나믹형 필름스피커를 제공하는데 그 목적이 있다.The present invention is designed to improve the problems of the conventional piezoelectric film speaker as described above, using a dynamic vibration device instead of a piezoelectric vibration device, but by attaching a cap on the voice coil installed in the magnetic circuit arc-shaped film It is an object of the present invention to provide a dynamic film speaker capable of faithfully reproducing a good voice signal over a wide band by being attached to both sides of the diaphragm.
이하 본 고안의 구성 및 작용효과를 첨부된 예시도면에 의거 상세히 설명하기로 한다.Hereinafter will be described in detail on the basis of the accompanying drawings and the configuration and effect of the present invention.

The edge part 4 is supported on the frame 1, and the dynamic vibration element 2 is a voice coil 8 in a magnetic circuit composed of a permanent magnet 5 and upper and lower plates 6,7. And the cap 9 is installed on the voice coil 8 to be bonded to the film vibration plate 3.
상기와 같은 구조를 갖는 본 고안은 다이나믹스피커의 특징인 넓은 음역에 걸친 양호한 재생능력과 우수한 음압출력 특성을 얻을 수 있을 뿐만 아니라 아치형 필름진동판을 사용하므로 음의 발산이 고르게 퍼져 나갈수 있게된다.The present invention having the structure as described above can not only obtain good reproducibility and excellent sound pressure output characteristics over a wide range, which is a feature of the dynamic speaker, but also use an arcuate film vibration plate, so that sound divergence can be spread evenly.
제1도는 본 고안에 따른 필름스피커의 정면도로서 프레임의 양측변에 다수의 다이나믹형 진동소자(2)가 배열되어져 있고, 상기 다이나믹형 진동소자(2)상에는 필름진동판(3)의 양측변이 접합되어져 있으며, 상기, 필름진동판(3)의 양측단은 상기 다이나믹형 진동소자(2)와의 접합부위로부터 절곡되어 엣지부(4)를 형성하면서 프레임(1)에 지지된 구조를 갖는다. 상기와 같은 구조로 인해 본 고안의 필름스피커는 구조가 간단하고 슬립형이면서도 양호한 음성재생능력을 가지게 된다.1 is a front view of the film speaker according to the present invention, a plurality of dynamic vibration elements 2 are arranged on both sides of the frame, and both sides of the film vibration plate 3 are joined to the dynamic vibration elements 2. The both ends of the film vibration plate 3 are bent from the joint portion with the dynamic vibration device 2 to form the edge portion 4 and have a structure supported by the frame 1. Due to the structure as described above, the film speaker of the present invention is simple in structure and has a good sound reproduction ability while slip type.
상기 구조를 좀더 상세히 설명하면, 제2도는 본 고안에 따른 제1도 스피커의 A-A선 단면도로서, 프레임(1)과 다이나믹형 진동소자(2) 및 필름진동판(3)의 결합구조를 나타내고 있는바, 다이나믹형 진동소자(2)는 프레임(1)상에 설치되어 상하 진동하면서 필름진동판(3)의 양측변으로 진동을 전달시켜주고, 상기 필름진동판(3)은 양측 엣지부(4)가 프레임(1)에 지지된 상태에서 다이나믹형 진동소자(2)의 진동에 따라 소리를 발생시켜 주게되는 것이다. 제3도에는 상기 다이나믹형 진동소자(2)의 진동구조가 좀 더 구체적으로 확대 도시되어 있는바, 다이나믹형 진동소자(2)는 영구자석(5)과, 상,하부 플레이트(6,7)로 구성되어 프레임(1)상에 지지된 자기회로 내에 보이스 코일(8)이 설치되고, 상기 보이스코일(8)상에는 캡(9)이 설치되어 필름진동판(3)에 접합된 구조로 되어있다. 여기서 상기 스피커의 작용을 좀더 상세히 설명하면, 상기 보이스코일(8)에 음성전류 신호가 인가될 경우 상기 보이스코일(8)은 자기회로부의 자계내에서 음성전류신호에 비례하여 상하운동을 하게되고, 이 상하 운동을 보이스코일(8)상에 설치된 캡(9)을 통해 필름진동판(3)으로 전달되어 음향을 발하게 된다.2 is a cross-sectional view taken along line AA of the speaker of FIG. 1 according to the present invention, and shows a coupling structure of the frame 1, the dynamic vibration device 2, and the film vibration plate 3. , The dynamic vibration device 2 is installed on the frame 1 and transmits vibration to both sides of the film vibration plate 3 while vibrating up and down, and the film vibration plate 3 has both edge portions 4 at the frame. The sound is generated by the vibration of the dynamic vibration device 2 in the state supported by (1). 3 shows the vibration structure of the dynamic vibration device 2 in more detail. The dynamic vibration device 2 includes a permanent magnet 5 and upper and lower plates 6 and 7. The voice coil 8 is provided in the magnetic circuit supported on the frame 1, and the cap 9 is provided on the voice coil 8 and bonded to the film vibration plate 3. Herein, the operation of the speaker will be described in more detail. When a voice current signal is applied to the voice coil 8, the voice coil 8 moves up and down in proportion to the voice current signal in the magnetic field of the magnetic circuit part. The vertical motion is transmitted to the film vibration plate 3 through the cap 9 installed on the voice coil 8 to emit sound.
상기와 같은 작용은 프레임(1)은 양측변에 설치된 다수의 다이나믹형 진동소자(2)에서 동시에 일어나게 되므로 아치형 필름진동판(3)은 균일하고 선명한 음향을 방사상으로 고르게 발산할 수 있게되며, 그에 따라 본 고안의 스피커는 다이나믹형 스피커의 장점인 넓은 대역에 걸친 양호한 음성재생능력을 충분히 살릴 수 있을 뿐만 아니라 종래의 압전형 필름 스피커에 비해 더욱 선명하고 균일한 음향을 얻을 수 있는 효과가 있다.As described above, the frame 1 simultaneously occurs in a plurality of dynamic vibration elements 2 installed at both sides, so that the arcuate film vibrating plate 3 can radiate uniform and clear sound evenly and radially. The speaker of the present invention not only can sufficiently utilize good voice reproduction ability over a wide band, which is an advantage of the dynamic speaker, but also has an effect of obtaining a clearer and more uniform sound than a conventional piezoelectric film speaker.
