본 발명은 콘형스피커의 음색변조 방지에 적당한 배플판 및 이를 이용한 스피커 시스템에 관한 컷이다. 종래에도 통상 목재판을 배플판으로 형성하여 콘형스피커 유닛이 안작될 자리를 원형으로 따내고 스피커시스템을 형성하도록 하는데, 콘형스피커 유닛은 저음방사 능률을 높이기 위해 배플판과 엔클로저가 사용된다,The present invention relates to a baffle plate suitable for preventing tonal modulation of a cone-shaped speaker and a speaker system using the same. Conventionally, a wooden board is formed as a baffle plate to form a speaker system in which a cone-shaped speaker unit is to be formed in a circle and a speaker system is used.
이 배플판은 스피커의 음압을 직접적으로 강하게 받게되어 그 음압에 견디는 강도와 구조를 가쳐야 하는데, 통상 대량생산되는 스피커 시스템에서 목재나 파티클보드를 사용하여 배플판으로 이용하였으나 구조나 강도상의 제약으로 음색변조를 피하기 어려웠다.This baffle plate is subjected to the strong sound pressure of the speaker directly, so that the strength and structure to withstand the sound pressure should be applied. In general, the baffle plate is used as a baffle plate by using wood or particle board in mass-produced speaker system. Tone modulation was difficult to avoid.
따라서 스피커 폰 전면에서의 음(+)에 대한 역위상 음(2)이 스피커로의 뒷면에서 방사되어 배플판을 침으로 인해 음압에 의한 미진동이 발생되어 악기소리, 목소리가 불명확하게 재생되며 여기에 통울림 현상이생겨서 음의 주파수가 낮은 저음이 흐려진다. 따라서 음의 확산이 어리워진다.Therefore, the anti-phase sound (2) against the sound (+) in front of the speaker phone is radiated from the back of the speaker, and the vibration of the sound is generated by hitting the baffle plate. There is a ringing phenomenon, and the low frequency of the low frequency sound is blurred. Therefore, the spread of sound becomes difficult.
따라서 본 발명은 이상과 같은 문제점을 감안하여 이루어진 것으로서 배플판을 충분한 강도보장을 위하여 한쌍의 판사이에 제조물질을 개재하여 고정시킨 구조로써, 이를 전면판으로 콘형스피커 유닛을 부설하여 음향기기 스피커 또는 카스피커를 형성케 하여 음압에 대한 저음영역의 손실없이 양호한 음질을 들을 수 있게 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above problems, and has a structure in which a baffle plate is fixed between a pair of plates to ensure sufficient strength through a manufacturing material, and a cone-shaped speaker unit is installed on the front plate of the sound equipment speaker or car. The purpose is to form a speaker so that good sound quality can be heard without loss of bass to sound pressure.
이하에서, 이를 첨부도면에 의해 상세히 설명하면 다음과 같다. 제1도에서와 같이 한쌍의 철판(10,20)사이에 제조물질(30)을 개재하여 고정시킨 구조로써 제2도에서와 같이 주변 여러개소에 압봉으로 프레스에 의해 결합고정시 고정함몰부(40)를 갖게하여 배플판(50)을 형성한다. 이때 제조물질로는 바람직하게 종이재로 형성하나, 그밖에 하드보드, 목재, 스치로폴, 스펀지, 코르크판, 탄소섬유판, 그라스울, 암면 및 점탄성수지 등을 사용할 수 있으며, 철판과의 결합방법의에 상기 프레스방법 이외에 리베팅, 냉간압접 등과 같은특수 용접 등으로 가능하다.Hereinafter, described in detail by the accompanying drawings as follows. As shown in FIG. 1, the structure is fixed between a pair of iron plates 10 and 20 with a manufacturing material 30 interposed therebetween. As shown in FIG. 40 to form the baffle plate 50. In this case, the manufacturing material is preferably formed of paper, but hard board, wood, styropol, sponge, cork board, carbon fiber board, glass wool, rock wool and viscoelastic resin, etc. may be used. In addition to the method, special welding such as riveting, cold pressing and the like is possible.
또한 이 배플판(50)을 음향기기 또는 카스피커 시스템의 전면판으로 스피커 유닛(SP)을 부설하여 음향기기의 스피커 시스템(60) 또는 카스피커 시스템(70)을 형성한다. 이때 배플판(50)은 철판 0.8mm일때 종이재를 1mm의 두께의 비율로 형성함이 바람직하다.In addition, the baffle plate 50 is provided with a speaker unit SP on the front plate of the sound equipment or the speaker system to form the speaker system 60 or the speaker system 70 of the sound equipment. At this time, the baffle plate 50 is preferably formed of a paper material at a ratio of 1 mm thick when the iron plate is 0.8 mm.
이상과 같은 본 발명의 작용효과를 살펴보면 스피커 유닛(SP)의 진동시 생기는 배압을 철판(10,20)에 의해 충분한 강도로 스피커의 저음을 해하지 않고 버티면서, 그 사이에 개재된 종이재(30)의 자체 히스테리시스로 흡수하고 제어하도록 되므로써 스피커 시스템의 고유 공진을 현저히 저하시킬 수 있어 저음영역 보호가 안전하여 양호한 음질을 갖게 한다.Looking at the operation and effect of the present invention as described above while holding the back pressure generated during vibration of the speaker unit (SP) with sufficient strength without harming the bass of the speaker, the paper material 30 interposed therebetween By absorbing and controlling by its own hysteresis, the inherent resonance of the speaker system can be remarkably lowered, so the bass area protection is safe and the sound quality is good.
이상과 같이 구성된 본 발명은 비교적 얇은 구조의 배플판으로써 형성할 수 있으므로 취급이 용이하며 스피커 시스템에 적용시 그 강도보장이 안전하며 저음영역이 음을 양호하게 들을 수 있는 효과가 있다.The present invention configured as described above can be formed as a baffle plate of a relatively thin structure is easy to handle, the strength is secured when applied to the speaker system and the bass region can hear the sound well.
