Description

双音管竖笛
技术领域
本发明涉及一种乐器,具体地说涉及一种双音管竖笛。
背景技术
现有的普通竖笛的发音原理是:气流经过簧片振动,直接进入笛管,然后进入音孔发出声音;这导致气流不能充分得到管壁的振动,使得发出的音色没有厚度与个性,吹奏低音音色虚弱。
发明内容
本发明为了解决上述问题,运用双管结构,提供一种使气流形成Z型流动,双管同时共振,音色富有个性,低音润厚,高音透亮,音域宽,发音灵敏,音阶及高低八度音准确,用气量小,转调方便的双音管竖笛。
本发明的目的通过以下技术方案来实现:一种双音管竖笛,包括笛头、第一音管、弧形弯管和第二音管,笛头内设有哨塞,第一音管上设有出气口,出气口处设有振动片,出气口外侧设有U型挡片用于平衡低音的振频,U型挡片高度为1厘米,也可根据第二音管的长度和内径而定,第一音管内部下端设有管塞,可调准八度音及高低音的音色平衡,弧形弯管和第二音管之间通过伸缩管连接,弧形弯管与第一音管相通,双管结构使气流形成Z型,加强双管管壁的振动,减少用气的流量,第二音管表面设有指孔。
本发明的进一步改进为,弧形弯管内部设有垫块。管塞在第一音管内部与出气口的距离可活动调节。弧形弯管与第一音管的接头处夹角为90°。指孔数量为6个或者8个。
本发明具有以下优点:运用双管形成Z型气流,使双管同时共振,音色富有个性,音量较大,低音润厚,高音透亮,音域宽,发音灵敏,音阶及高低八度音准确,用气量小,转调方便。

图2为本发明的侧视图;

具体实施方式
为了加深对发明的理解,下面将结合实施例和附图对本发明作进一步详述,该实施例仅用于解释本发明,并不构成对本发明保护范围的限定。
如图1、2所示的一种双音管竖笛,包括笛头1、第一音管2、弧形弯管3和第二音管4,笛头1内设有哨塞5,第一音管2上设有出气口6,出气口6处设有振动片7,出气口6外侧设有U型挡片8,U型挡片8可控制气流的流动方向,加强振动片7的振动,且U型挡片8的大小高低与第一音管2的粗细匹配适合,达到音频率的平衡,第一音管2内部下端设有管塞9,管塞9可使气流反向运动,产生封闭第一音管2的效果,管塞9在第一音管2内部与出气口6的距离可活动调节,通过管塞9的上下移动,可以精确调整各音及高低八度的音,弧形弯管3和第二音管4之间通过伸缩管10连接,弧形弯管3与第一音管2相通且与第一音管2形成90°夹角,弧形弯管3内部设有垫块12使弧形管道缩小,根据不同的气流,调节伸缩管10的长度控制第二音管4的长短来控制音准,第二音管4表面设有6个或8个指孔11。
本发明双音管竖笛的发声原理是,当气流进入哨塞5,形成细小的气流冲击振动片7,使第一音管2振动发音,气流经过管塞9返流产生二次振动,此时部分气流从出气口6逸出,出气口6处的U型挡片8控制气流的方向与流量,另一部分气流进入第二音管4,U型挡片8的高度与第二音管4的长度成正比例,使气流形成Z字型产生平衡共振,并通过指孔11控制不同音高。
