This introduction is meant to a guide to those who have little or no knowledge of violin construction,

particularly concerning the sound post.这是为了引进后指导那些很少或小提琴谁不知道的建设，特别是有关的声音。 Hence it will be largely explained in simple, practical terms.因此，它在很大程度上解释简单，实用范围。 Below is a diagram of a violin cut laterally throught the center that illustrates the position of the sound post in a completed violin.下面是一个小提琴图一切横向以为中心，说明了小提琴的位置完成了一个扎实的研究。

The sound post is a small dowel of Spruce that is held by friction between the top and back plates of a violin (viola, cello, or string bass), situated under the treble side of the bridge.声音后桥是一个小销子云杉该一方是由摩擦高音举行的顶部和背面板的小提琴（中提琴，大提琴下，或者位于弦低音）。 It has both structural and tonal importance.它具有结构和色调的重要性。

Structurally, it supports the top plate, acting like a pillar under the bridge.结构上，它支持顶板，如一座桥梁的支柱作用。 Without it, a violin would "cave in" on the treble side.没有它，小提琴将“洞穴”在高音方面。 A good violin, however, may not be harmed if it is without a sound post for a short period of time, but an instrument should not be left in this situation for long.一个好的小提琴，不过，可能不会受到伤害，如果是没有时间期限短的一听起来员额，但1 instrument should不能long左in有关的情况。

Acoustically, the sound post transfers vibrations from the top plate to the back plate of the instrument.声，声音由转让后的上板振动对仪器的背面板。 It also alters the vibration of the top plate.它也改变了板振动的顶部。 Its placement, length, thickness, grain orientation, and wood selection influence the tone of an instrument.其位置，长度，厚度，晶粒取向，影响和木材的音色选择一个。 An instrument without a sound post will sound weak, thin and hollow.一个没有扎实的仪器将声音微弱，薄和空洞。

On the bass side of an instrument is a "bass bar", a cross section of which can be seen in the illustration above.在低音乐器一边是“低音栏”，一个截面，可以在上面看到的例子。 It has both acoustic and structural roles as well.它既有声学和结构的作用以及。

  第1部分：关于扎实的二传手，并选择木材

A: The Sound Post Setter 答：扎实的二传手

The sound post setter is a small metal tool about 23cm/9" long. The sharp point at one end is pressed into the post to hold it for inserting into the instrument. The other end, which looks like a hand, is for moving the post once it has been placed in the instrument.声音后二传手是9“长大约23厘米的小金属工具/。尖的一端是在压入后举行的工具它的插入。其他目的，它看起来像一个手，是为移动后一旦被放置在仪器。

B: Selecting the Wood 乙：选择木材

The post is made of a dowel of spruce, usually about 5.5-6mm in diameter for a full size violin.该职位是由一，销钉，云杉通常大约为1小提琴全尺寸5.5 - 6mm的直径。 The post must be small enough to fit through the f-hole at the notches, which is usually the widest point.该职位必须足够小，以适应通过的F点的孔槽，这通常是最广泛的。 This is true for all instruments (from the smallest violin to the largest bass).这是真正从最小的小提琴所有工具（到最大的低音）。 The grain should be fine, straight and even, preferably matching the wood that was used in the top of the instrument. So if the to plate instrument is coarsely grained, use a post with wider grain; if it is filely grained, use a post that has closer growth rings.粮食要罚款，甚至直接，最好的仪器匹配的木材被用来在首位。因此，如果对粗颗粒板仪器，使用后有更多的粮食，如果它是filely颗粒，使用后具有更密切的年轮。

 第2部分：确定高度和拟合后

A: Determining the Height of the Post 答：确定后的高度

Once a sound post setter has been obtained, and an appropriate piece of material selected, the next step will be to cut and fit the sound post.一旦一个扎实的制定者已获得适当的物质和一块选定，下一步将是削减和装修后的声音。 There is a tool which is a great help to determining the height of the post, called a sound post gauge, which greatly simplifies this process. 有一个工具，它是一个很大的帮助，以确定该职位的高度，称为扎实的了解，从而大大简化了这一过程。

I will also explain here explain how to do it without a guage. A small needle file can be used to ascertain the approximate height for the post.我也将在这里解释解释如何做到这一点没有一个衡量标准。一个小针文件可以被用来确定后近似的高度的。

• Insert the file (or other appropriate tool) in the upper 'eye' of the f-hole until it touches the back of the instrument, making sure that the file is perpendicular to the plane of the instrument (parralell with the ribs, or sides).插入文件（或其他适当的工具）在上'眼睛文书'的F -洞，直到它触及的背面，并确保该文件是两侧平面垂直于该文书或（parralell与肋骨， ）。
• Place your thumb nail on the file to mark the length needed.该文件放在您的拇指指甲的长度为纪念需要。
• Mark this length on the sound post. The end grain direction of the sound post must run perpendicular to the grain in the top .纪念这个长度的声音后。 结束后的声音粮食必须运行方向垂直的粮食在顶部 。 This is important to the performance of the instrument.这是重要的仪器的性能。
• Cut the dowel somewhat longer than what is required for the post剪切销钉略长于所需要的职位
• With a single-cut file, file the ends at angles to match the arch of the top and the back.由于采用单切的文件，文件在两端角度匹配的顶部和背部拱。

B: Inserting and Fitting the Post 乙：插入和拟合后

 第3部分：定位和调整后

The correct position of the sound post is behind the bridge foot (toward the tailpiece), as seen in the above diagram.声音后的正确位置是后面的桥脚尾翼（2224），为图出现在上面。 Generally, if the sound post is too short, the upper wing of the f hole will sink with the strings tensioned and the post in the above position.一般来说，如果声音后太短，机翼上的F孔的意愿水槽与张弦和位置张贴在上面。 If it is to tall, the wing will protrude.如果要高，机翼会凸显。 Adjust as neccessary.调整是必要的。

To be continued.要继续进行下去。

The sound post can easily be seen through the f-hole on the treble side of the instrument.声音后很容易识破的F -关于该文书的高音方孔。
