复合功能吉他音梁结构的形式与工作状态
Dual Function Guitar bracing Introduction
一． 传统支撑与连接功能共存的音梁结构
Traditional bracing system with both support and connection function.
这种传统的音梁结构形态的琴箱，在面、背、侧三者之间，由于没有共同稳定的依附体，整个琴箱处于一种悬浮的动态中。当其中的某一部分（或几个部分同时）发生收缩变化时，会导致相邻的其他部分，也会被同步产生牵引而发生变形变化，尤其是面、背板的收缩变化幅度最为明显），最终导致整个琴箱的整体结构同时发生变形变化。从而影响琴箱的最初共鸣设计要求，琴体的稳定性寿命也会受到较大的影响。
Above traditional bracing structure has no solid foundation on top, sides, and back. Whole guitar body is more or less like in a floating status. When one(or some) parts move against environment change， it(they) will bend/twist due to the change from its neighbor part.（especially the shrinkage of top and back），The result is whole body bend/twist and affect the original body structure design.，as well as guitar life time.
二． 满氏支撑与连接功能分开的双层音梁结构Mann’s innovation Dual function bracing system separating support and connection functions.
这款音梁结构，由于它的连接与支撑功能，分别被下（1）上（2）两层的独立部分所分担。当面板和（或）背板部件因为空气湿度的变化而发生收缩变化时，连接层不会同步产生等位长的收缩变化，从而不会导致相邻侧板部件被同时大幅度受到牵引而产生明显的变形变化。由于面板和（或）背板部件受到连接层音梁的牵拉限制，它们的凹凸收缩变化，也会受到一定的保护性限制。
相反，当吉他处在标准音的状态下时，琴箱受到琴弦的牵拉，侧板受到向下的折压力时，侧板的两边就会发生向内收拢或向外伸展的被动变化，从而造成琴箱的腰部会发生明显的弯曲变化。侧板两边的距离变化，也会同步带动面板和（或）背板产生相应的凹凸变化，从而也会影响到面板和背板的正常自然工作状态（包涵它们的振动张力和反射弧形）。满氏双层音梁连接层部分的支撑和牵拉双向功能，对减少侧板的这种双向性变化，有很好的帮助功用。
同时，由于面、背、侧它们三者之间的音梁，都互相粘连接着在一起，形成了一个互连的稳定闭环体。面、背、侧板，不再是粘贴在一个悬浮性的音梁结构体上，整个琴箱的稳定性，也就得到了很好的保障。
This innovated bracing design contain two parts: Connection function(1) and Supporting function(2) Two independent parts
When top or back shrink/twist due to the environment humidity Connection function does not move against the top movement.，Also won’t pull the sides according the movement.。In another hand, top and sides structurally limited by connecting part of bracing, they will be limited in changing dimension and protected then stretch less.
In the opposite way, when the guitar under standard tuning, body is under tension of the strings, the sides plate is subjected to folded into the center of guitar. The side plate on both sides will be inward or extended changes, resulting in a significant bending of the waist of the body. Changes in distance on both sides of the side plate will also simultaneously drive the top and/or the back plate to produce undesirable corresponding bump changes, which will also affect the normal natural working status of the panel and back (including their vibration and reflection). The support and pull-bidirectional function of the two-way connection layer part of the Mann's dual function bracing design is very helpful to reduce this two-way change of the side plate.
At the same time, because of the top, back, sides between them between the sound bracings, are glued together, forming an interconnected stable closed system. Top, back, sides plate, are no longer pasted on a suspended bracing structure, creates a stability of the body system.
三．传统的音梁系统就像是放置于地表面上，没有地面对其固定支撑住桥墩的桥梁模型。面、背板的伸缩变化，都会导致侧板的左右位移变化。
Traditional bracing systems are like bridge models placed on the ground surface without the ground to hold the bridge pier. The scaling change slabs of the face and back plate will cause the left and right displacement changes of the side plate.
满氏音梁系统，才是真正屹立于地里的桥梁结构。无论是面背板的伸缩变化，还是侧板的左右位移变化，对其相邻部件的影响都是非常小的。
Mann's dual function system is the bridge structure that really stands on the ground. Whether it is the scaling change of the top and back plate or the change of the left and right displacement of the side plate, the effect on its adjacent components is very small.
四．满氏双层音梁结构，就像手机、电脑的操作系统一样，是一个可以兼容各种原声吉他产品结构的平台，欢迎大家融入此系统"。
Mann’s dual function bracing system, like OS of mobile phone, computer, is compatible with a variety of acoustic guitar structure platform, welcome to integrate into our system".
