Abstract

一种金属琴杆带共振片板胡,涉及一种民族乐器,其特征是:琴杆采用高强薄壁金属管[2],上为方形管[4],下为扁圆形管[13],方形管[4]塞有硬杂木[5],有弧形金属共振片[3],共振片下劈出2个挂弦钩[10],联接管[11]将高强金属管[2]、弧形金属共振片[3]与底托[12]紧配合联接成一体。由于高强金属管强度优于传统红木类琴杆,金属琴杆在弦拉力下和演奏中压揉弦保证其弦音准可靠稳定,结构简单,节省高级稀缺木料,降低成本、解决了木质受力和受潮跑调难题,且轻于红木一半重量,加上弧形金属共振片起到共振作用,音色别具一格,演奏时上轻下重稳定性优越。用在民族器乐合奏、伴奏、独奏等场合发挥其特色。

Description

一种金属琴杆带共振片板胡
1、技术领域  本实用新型涉及一种民族乐器,具体地说是涉及一种金属琴杆带共振片板胡。
2、背景技术  板胡是我国古老的民族乐器,有3百多年的历史,用椰子壳做共鸣箱,梧桐板做发音面板,用红木等做琴杆,采用钢弦,用马尾弓拉弦使发音板振动,在共鸣箱的作用下,发出较大声音。
目前采用高级昂贵稀缺的老红木加工琴杆,由于受弦的拉力、受气候潮湿变化使琴杆变形导致弦跑调。板胡的音乐表现力远没有达到人们欣赏音乐、歌舞、戏曲、影视剧等需求的最佳音乐表现力,渴望有多种音色登上舞台,其音质、音色、音量仍需要改善。
3、发明内容  本实用新型的目的是为民族乐器提供一种金属管琴杆带共振片板胡,定弦稳定可靠、长期不跑调、重量轻、音量增大、音质纯正、音色清脆悦耳、有效的增加音乐的表现力,其结构简单,成本低、携带方便等优点。
为达到上述目的,本实用新型的技术方案是这样实现的:琴杆采用高强薄壁金属管上为方形管,下为扁圆形管,方形管内塞有硬杂木,有弧形金属共振片,有挂弦钩,连接管。
4、附图说明  图1是金属琴杆带共振片板胡主视图,图2是图1中左侧视剖面图,图3是图1中A-A剖视图及局部剖面图,图4是图1中B-B的剖视图,图5是图1中C-C的剖视图。
5、具体实施方式  参照附图将详细叙述本实用新型的具体实施方式。
琴杆采用高强薄壁金属管,用摸具加工成型,上段为方形管[4],下段为扁圆形管[13],制成金属琴杆[2],方形管[4]塞有硬杂木[5]用做安装琴弦轴[1],以保证琴轴牢固耐久,弧形金属共振片[3]用金属薄板,厚0.3mm-1.2mm,用摸具压制成,其下部劈出2个挂弦钩[10]。组装:将共鸣箱[6]穿入金属琴杆[2],再镶装联接管[11],穿入弧形金属共振片[3]紧配合,再插入底托[12],板胡主体制做及安装完成。试用,将琴弦[9]套在挂弦钩[10]上压过琴码[8]到琴弦轴[1],便可用弓子拉弦调音,琴码[8]在发音面板[7]上半部,各个环节要经过多次反复调试中找到音色、音量及音质的最佳状态。
