Abstract

本发明公开了一种低音六角二胡，包括琴码、琴杆，所述的琴码包括琴码支架和床型桥码，床型桥码的上部比床型桥码的下部高，床型桥码支撑住琴弦。琴码支架为城墙垛口型，床型桥码的支撑脚是与琴码支架嵌合的城墙垛口型。琴杆中心靠近擦弦点上方设立分叉体，分叉体的内侧和外侧均为内凹型，分叉体的底部为圆弧型。本发明既保证了擦弦点位于最佳位置，又充分利用了加大的六角共鸣体的音量，实现了音色和音量的完美统一。具备适于演奏低音区域的音乐，使民族拉弦乐器的音域覆盖更广，满足民族室内乐的演奏需求。另外当演奏者不需要使用琴弓的时候，就可以琴弓向上，无阻碍地放置到琴杆分叉体上，演奏者就可以做其他的演奏动作了。

Description

低音六角二胡
技术领域
本发明涉及中国民族拉弦乐器，特别涉及二胡技术领域。
背景技术
二胡是一种常用的中国民族拉弦乐器。二胡由琴筒、振动膜、琴杆、琴头、弦轴、千斤或山口、琴码、琴弓和琴弦等主要部件组成。二胡的发音原理是：运弓，使弓毛和琴弦相互摩擦，琴弦的有效振动范围受到压迫振动，通过琴码把音源传递给振动膜，振动膜将振动波传入琴筒，与琴筒内固有频率产生共振而引起共鸣发声。
现有二胡音色柔和、优美，穿透力很强，但是在大型的民族室内乐的演奏中，民族弦乐的拉弦乐器都存在低音不足的问题，低音位置空缺，现用西洋大提琴来代替，故民族室内乐中不能完全做到乐器的民族化与声音的协调性。
发明内容
针对民族弦乐的拉弦乐器存在的缺陷，本发明提供了一种低音充分的低音六角二胡，其目的在于在大型的民族室内乐的演奏中，改善二胡低音音质，提高民族乐器的协调性。
本发明包括琴码、琴杆，所述的琴码包括琴码支架和床型桥码，床型桥码的上部比床型桥码的下部高，床型桥码支撑住琴弦。琴码支架为城墙垛口型，床型桥码的支撑脚是与琴码支架嵌合的城墙垛口型。
作为本发明的进一步改进，琴杆中心靠近擦弦点上方设立分叉体，分叉体的内侧和外侧均为内凹型，分叉体的底部为圆弧型。
由于二胡琴码采用了床型桥码的结构，既保证了擦弦点位于最佳位置，又充分利用了加大的六角共鸣体的音量，实现了音色和音量的完美统一。具备适于演奏低音区域的音乐，使民族拉弦乐器的音域覆盖更广，满足民族室内乐的演奏需求。另外二胡琴杆中心靠近擦弦点上方设立可悬挂琴弓的分叉体，当演奏者不需要使用琴弓的时候，就可以琴弓向上，无阻碍地放置到琴杆分叉体上，演奏者就可以做其他的演奏动作了。

具体实施方式：
下面结合附图，对本发明进行具体描述。
低音六角二胡的共鸣体为加大的六角形箱体7，振动膜为整块蟒蛇皮面板6，两侧有出音孔（音窗），本发明的琴码5包括固定连接的琴码支架52和床型桥码53，并固定在琴码底盘51上，琴码底盘51与蛇皮面板6固定，床型桥码53的上部比床型桥码53的下部高，床型桥码53支撑住琴弦3。琴码支架52为城墙垛口型，床型桥码53的支撑脚是与琴码支架52嵌合的城墙垛口型。琴弦3的有效振动范围是床型桥码53的上部到山口2的范围。床型桥码53的上部与擦弦点8的距离是山口2到擦弦点8的七分之一到九分之一。作为本发明的进一步改进，琴杆1中心靠近擦弦点8上方设立琴杆分叉体4，琴杆分叉体4的内侧和外侧均为内凹型，琴杆分叉体4的底部为圆弧型。当演奏者不需要使用琴弓9的时候，就可以把琴弓9向上，无阻碍地放置到琴杆分叉体4的内侧和外侧的凹型处，利用琴弓9的弓毛弹性固定在琴杆分叉体4上，并且不碰到琴弦。演奏者就可以做其他的演奏动作了，比如演奏拨弦，这样就不会影响到拨弦的演奏。
综上所述，本发明提供的一种低音六角二胡，对现有二胡的功能、性能进行了明显的改进，使其具备低音区域的演奏功能，丰富了演奏形式和风格。由于箱型共鸣体的体积变大，音量增加，二胡的演奏方式不变，但是音色在低音演奏区域得到了更大程度的发挥，弥补了原先拉弦乐器在低音方面的不足。本发明应用不局限于二胡，包括民族弦乐的拉弦乐器，均在保护范围以内。
