The utility model relates to a portable knee zither, belonging to the technical field of musical instruments. Including the panel, bottom plate, side plate and is arranged in the string on the panel, front and rear beams, strings of code, set the peg board between the panel and the bottom plate, which is characterized by the panel, the base plate and the side plate length is less than 140cm, before the beam beam, the peg board and the panel point contact support, resonant cavity formed between the panel and the bottom plate. The big end of the cavity is provided with a counterweight. The invention has the advantages of scientific and reasonable structure, easy manufacture and low cost. The beam to beam, beam to the head before the treble bass is about 27cm, at about 11cm, there is conducive to shorten the overall length of the weight set at the head of the Zheng, Zheng in the cavity between the panel and the bottom plate, easy to carry and put on the knee playing. The whole cavity between the panel and the bottom plate is a resonance body, the sound box is enlarged, the resonance is increased, and the sound quality is improved.
【技术实现步骤摘要】
本专利技术涉及一种古筝的结构,特别是便于携带的可放于膝上弹奏的 古筝,属于乐器
技术介绍
古筝是一种民族乐器,很受人们的欢迎。现有的古筝由面板、底板 和弦等构成,有大头(筝首)、小头(筝尾),面板上设有前梁(岳山)、 后梁(尾岳山)、弦码,弦通过前梁(岳山)、后梁(尾岳山)和弦码扣 在面板上,为了扣弦,在面板和底板之间的筝腔的前梁、后梁部位设置 弦轴板(或称弦钉板)扣弦,直接与面板接触,使筝腔的前、后两端各 构成一个腔(或盒)与中腔分开,底板上有筝首出音孔和筝尾出音孔。这种古筝的筝身比较长, 一般在163cm左右,都需要将筝放在架上或桌 子弹奏,前梁是直的,从前梁到大头板高音、低音均为15cm左右,弦 轴板直接与面板接触,影响筝的音质。
技术实现思路
本专利技术的目的是要提供一种便于携带的可放于膝上弹奏的,音质好 的便携式膝筝。本专利技术的目的是这样实现的,便携式膝筝,包括面板、底板、侧板 和设置在面板上的弦、前梁(岳山)、后梁(尾岳山)、弦码(或称琴码), 设置在面板和底板之间的弦轴板,其特征是所述的面板、底板和侧板的 长度均小于140cm,前梁(岳山)为斜梁,弦轴板与面板点接触支撑, 面板和底板之间构成共鸣腔体。所述的腔体内的大头处设有配重。本专利技术结构科学合理,生产制造容易,成本低。将前梁(岳山)改为斜梁,高音处前梁到大头为27 cm左右,低音处为llcm左右,有利 于弹奏者放置膝上时,使筝体保持平衡。在面板、底板之间的筝腔内的 大头处设置配重,便于携带和放于膝上弹奏。为紧弦而设置的弦轴板(或 称弦钉板)与面板采用点接触支撑,使面板与底 ...
