Abstract

本实用新型涉及一种用于改善钢琴弹奏音响效果的多音桥钢琴发音系统。此种钢琴发音系统由钢板(1)、木制音板(2)、琴弦(3)和音桥(4)组成,在现有钢琴的钢板(1)和音板(2)之间沿平面均布有8—12个木制音桥(4)。采用本实用新型可以获得良好的音响效果,使其兼有共鸣音、共振音、立体音、穿透音,且各音区声音均衡,音量增大坚实,音色更加优美动听。本实用新型科学简便,易于实施,效果良好,宜于推广应用。

Description

多音桥钢琴发音系统
本实用新型涉及一种用于改善钢琴弹奏音响效果的多音桥钢琴发音系统。
钢琴是在世界各地广泛流行的一种弹奏乐器,以其音域宽广、音色浑厚、雄壮、优美动听而被称为乐器之王。从音响学分析,物体振动产生声音,整体振动产生基音,钢琴作为一种乐器要想改善音响效果应当从改善基音上做工作。然而,目前国内外通常使用的各种类型的钢琴在制作上恰好忽略了整体振动,钢琴琴箱内钢板(钢骨)与木制音板之间没有接触点,只在边角部位有支撑点。此种结构的发音系统在钢琴弹奏时只能产生琴箱、琴体的共鸣音,缺乏琴体的共振音,从而影响钢琴发音的整体效果,使人听起来有音量大而空、声音散而不够清晰的感觉。
本实用新型的目的在于提供一种可以改善钢琴弹奏音响效果的多音桥钢琴发音系统。
本实用新型实施方案如下。此种钢琴发音系统由钢板、木制音板、音桥和琴弦组成,其总体结构与通常钢琴大致相同,只是在钢板与木制音板之间沿平面均布有8--12个木制音桥。这样,由于钢板与音板之间增加了接触点,使得钢琴在弹奏过程中整个发音系统作整体振动,即可形成共振而产生基音,达到改善弹奏音响效果的目的。
本实用新型设计科学简便,易于实施,利用此种钢琴发音系统只需对现有钢琴发音系统结构稍加改造,即可获得良好的音响效果,使其兼有共鸣音、共振音、立体音、穿透音,且各音区声音均衡,音量增大坚实,音色更加优美动听。本实用新型为改善钢琴弹奏效果锦上添花,宜于广泛推广应用。
图1为本实用新型的总体结构示意图(俯视图)。
图2为本实用新型的侧视图。
以下结合附图对本实用新型的实施加以说明。
如附图所示,本实用新型由钢板1、木制音板2、琴弦3和音桥4组成。其中,音桥4为长、宽、高分别为50、20、20mm的长方体,用白松木制作。安装时将预制的8--12个(具体数量因琴型而定)音桥沿平面均匀地分别塞入各部位的钢板和音板之间,用小锤轻轻敲紧并用胶粘合即可。其他各部件如钢板1、音板2、琴弦3与现有件相同。
