今年我厂试制的新型六弦琴,在共振板的音响结构上,改革其传统的横梁结构(见图一)为横直梁新型结构(见图二),对提高产品的音色音量取得良好的效果。六弦琴的音梁结构,除了象提琴开成 f 形音孔的“吉普逊”(GEBSON)吉他外,其传统琴的平行横梁式结构,长期以来为国内外普遍应用。我们认为在振动性能方面平行横梁式结构存在以下缺陷:①共振板的振动范围受到限制;②共振板的高、低音振动区域处干对等平衡的状态,未能适应在音响上的高频与低频的不同要求;③不能充分发挥音梁在共振板中 This year, our new trial of the six-stringed instrument, in the resonant structure of the sound board, the reform of its traditional beam structure (see Figure 1) as a new vertical beam structure (see Figure 2), to improve the tone volume of the product achieved good results. In addition to the “Gibson” (gibson) guitars that make up f-shaped holes like a violin, the parallel beam structure of a traditional harp has long been widely used both at home and abroad. We consider that the parallel beam structure has the following defects in terms of vibration performance: ① The vibration range of the resonance plate is limited; ② The equilibrium state of the resonance plate in the high and low frequency vibration areas is not matched with the high frequency Low frequency of different requirements; ③ can not give full play sound beam in the resonant board
