3 : 받침구 4 : 원추형 받침추3: Base 4: Cone Base
5 : 나선부 6 : 고정나트5: Spiral part 6: Fixed nut
본 고안은 스피커 시스템(SPEAKER SYSTEM)과 바닦면과의 접촉면적을 최소화하여 스피커 시스템과 바닦면과의 상호 진동전파를 극소화 시키고 스피커 시스템을 바닦으로부터 일정간격 이격시킴으로써 불필요한 저역으로 증가를 방지 하도록한 진동전파방지용 받침구에 관한 것이다.The present design minimizes the contact area between the speaker system and the floor, thereby minimizing the mutual vibration propagation between the speaker system and the floor, and by separating the speaker system from the floor by a certain distance to prevent unnecessary low frequencies. It relates to a propagation prevention base.
구체적으로는 스피커시스템의 캐비네트(CABINET)하부를 천공하여 고정너트를 결합시키고, 원추형받침추의 상단에 나선부를 형성하여 고정너에 체결시킴으로서 스피커시스템과 바닦면과의 접촉면적을 최소화하고 일정한 간격을 바닦면으로부터 이격시킴으로서 진동을 방지하고 나사의 길이를 조절하여 바닦면에 의한 저음의 반사량을 조절할 수 있도록 한것이다.Specifically, the fixing nut is combined by drilling the bottom of the cabinet of the speaker system, and a spiral is formed on the upper end of the conical support weight to be fastened to the fixing nut to minimize the contact area between the speaker system and the floor surface and to maintain a constant interval. It is to be separated from the floor to prevent vibration and to adjust the length of the screw to adjust the amount of reflection of the bass by the floor.
종래의 스피커 시스템은 제4도에 도시한 바와 같이 단순히 바닦면에 설치하거나 벽돌 또는 나무상자위에 올려놓고 사용하여 왔다.Conventional speaker systems have been used simply on the floor or as placed on bricks or crates as shown in FIG.
이러한 경우 스피커 시스템의 캐비네트와 바닦면 사이의 진동 전파방지에 대한 해결책이 전혀없어 바닦공진이 스피커 시스템으로 전달되어 음질이 열화되거나 바닦공명 현상에 의하여 불필요한 저역이 증가하여 음의 균형을 끼뜨리게 되고 명료도를 저하시키게 되었다.In this case, there is no solution to preventing vibration propagation between the cabinet and the floor of the speaker system, and the floor resonance is transmitted to the speaker system, resulting in deterioration of sound quality or an increase in unnecessary bass due to floor resonance. The intelligibility was reduced.
또한 바닦면을 통하여 다른 부분으로 진동이 전파되어 턴테이블의 하울링(Howing)및 콤팩트 디스클 플레이어의 하울링 등에 의한 디지탈의 오동작을 발생시키고 불필요한 저역의 증가와 소음의 전파로인해 청취자에세 불쾌감을 갖도록 하였다.In addition, vibrations propagate to other parts through the bottom surface, causing digital malfunction due to howling of the turntable and howling of the compact disc player, and causing unpleasantness to the listeners due to unnecessary low frequencies and noise propagation. .
본 고안은 이하 같은 결점을 해결하고자 안출된 것으로서 하단에 원추형 받침추가 형성되고 그 상부로 나선부가 형성된 받침구를 스피커 시스템의 캐비네트 하부에 결합된 고정너트에 체결시켜 스피커 시스템과 바닦면사이의 접촉면적을 최소화 하여 불필요한 저역의 증가를 방지하고 소음의 전파를 줄이며 다른 음향기기등에 진동이 전파되는 것을 방지하여 진동전파에 의해 발생하는 음향기기등의 오동작의 발생을 제거하는데 목적이 있는 것이다.The present invention was devised to solve the following drawbacks, and the contact between the speaker system and the floor surface is fastened by fastening a support hole formed with a conical support at the bottom and a spiral formed at the top thereof to a fixing nut coupled to the lower part of the cabinet of the speaker system. The purpose is to minimize the area to prevent unnecessary low frequencies, reduce the propagation of noise, and to prevent the propagation of vibrations to other sound equipments, thereby eliminating the occurrence of malfunctions of sound equipments caused by vibration propagation.
이와 같은 목적을 달성시킬 수 있는 본 고안의 구성을 첨부된 도면에 의해 설명하면 다음과 같다.Referring to the accompanying drawings the configuration of the subject innovation that can achieve the above object is as follows.
제1도는 본 고안의 사용상태 이고, 제2도는 본 고안의 진동전파량을 도시한 것으로써 발생한 진동량보다 캐비네트의 내외부로 전파되는 진동량이 극소화된것을 나타내었으며 제3도는 고무쿠션을 이용하여 진동흡수를 좀더 효율적으로 한것이고, 제4도는 종래도로서 발생된 진동량이나 그 이상으로 캐비네트 내외부에 전파되는 것을 나타낸 것이다.FIG. 1 is a state of use of the present invention, and FIG. 2 shows the amount of vibration propagation of the present invention, which shows that the amount of vibration propagated into and out of the cabinet is minimized rather than the amount of vibration generated. The vibration absorption is made more efficient, and FIG. 4 shows the propagation inside and outside of the cabinet by the amount of vibration generated as the conventional figure or more.
도시한 바와 같이 하단에 원추형 받침추(4)가 형성되고 그 상부로 나선부(5)가 형성된 받침구(3)를 스피커 시스템(1)의 캐비네트(2) 하부에 다수개 결합된 고정너트(6)에 체결시킨 구조로 된 것이다.As shown, a fixing nut in which a plurality of support holes 3 having a conical support 4 formed at the bottom and a spiral 5 formed thereon are coupled to the lower part of the cabinet 2 of the speaker system 1. It is a structure fastened to (6).
제2도는 원추형 받침추(4)와 나선부(5) 사이에 고무쿠션(7)을 갖도록한 응용 예시도로서의 진동의 전파를 고무쿠션(7)에서 흡수하도록 하여 진동 전파방지를 좀더 효율적으로 이루어 지도록한 것이다.2 is a diagram illustrating an application in which the rubber cushion 7 is provided between the cone-shaped support weight 4 and the spiral portion 5 so that the vibration of the vibration is absorbed by the rubber cushion 7, thereby preventing vibration propagation more efficiently. To make it.
미설명부호 8은 바닦면 이다.Reference numeral 8 is on the bottom.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
일반적으로 스피커 시스템(1)과 바닦면(8)사이에 전파되는 진동속도의 함수관계를 살펴보면, 다음과 같다.In general, look at the functional relationship of the vibration speed propagated between the speaker system (1) and the floor surface (8), as follows.
캐비네트(2) 저면의 면적을 S라 하면 스피커 시스템의 자체하중 W에 의하여 바닦면에 작용 힘는 힘 F는 F=S·P가 된다.If the area of the bottom surface of the cabinet 2 is S, the force F acting on the floor by the self-load W of the speaker system becomes F = S · P.
이때 P는 단위면적당 작용하는 힘이다.P is the force acting per unit area.
그리고, 기계적인 임피던스(Impedance)를 Zm이라 하고 스피커 시스템 캐비네트(2)의 저면에 진동하는 속도 V를 구하면 V=F/Zm이 된다.Then, the mechanical impedance (Impedance) is Zm and the velocity V oscillating on the bottom of the speaker system cabinet 2 is obtained as V = F / Zm.
그러므로 진동의 속도 V=P·S/Zm이 됨르로 캐비네트(2)와 바닦면(8)의 접촉면적이 작을수록 진동속도 V가 작게 되므로 바닦면(8)과 스피키 시스템(1)의 접촉면적을 최소화시키면 진동이 전파되는 것을 극소화할 수 있는 것이다.Therefore, as the speed of vibration V = P · S / Zm, the smaller the contact area between the cabinet 2 and the floor 8 is, the smaller the vibration speed V is, so that the surface of the floor 8 and the speech system 1 Minimizing the contact area minimizes the propagation of vibrations.
그리고, 나선부(5)의 길이를 임의적으로 조정하여 바닦면(8)과 캐비네트(2)와의 거리를 조절함으로서 저음의 증감을 조절할 수 있는 것이다.And, by arbitrarily adjusting the length of the spiral portion 5 by adjusting the distance between the bottom surface 8 and the cabinet (2) it is possible to adjust the increase and decrease of the bass.
이와 같은 본 고안은 스피커 시스템(1)의 진동전파를 방지하여 음향기기의 오동작을 제거하고 저음의 증가를 방지하여 음질의 명료도를 얻을 수 있는 등의 효과가 있는 매우 유용한 고안인 것이다.The present invention as described above is a very useful design that has the effect of preventing the vibration propagation of the speaker system (1) to remove the malfunction of the sound equipment and to prevent the increase of the bass to obtain the clarity of sound quality.
