Efficient-vibration vertical piano

Abstract

The invention relates to a musical instrument, namely an efficient-vibration vertical piano. The piano comprises a soundboard (1), a cast iron plate (2), tuning pegs (3), strings (5), a string nut (4), a string saddle (7) and string-hanging poles (6). The strings (5) are supported by the string nut (4) and the string saddle (7). The two ends of each string are respectively fixed to one of the tuning pegs (3) and one of the string-hanging poles (6). A plurality of keys of the piano are corresponding to the strings (5) in different zones. The piano is characterized in that: the cross section of the string nut (4), namely the cross section of the string nut (4) along the passing direction of the strings (5), is an obtuse triangle formed by two acute angles and one obtuse angle, and the obtuse angle is at one side of striking points of the strings (5) and is connected to the plate surface of the cast iron plate (2). Beneficial effects of the piano are that: vibration space behind the string striking points is largely broadened, so that the vibration at the two sides of the striking points is more balanced, the pronunciation efficiency of the strings is largely increased, the vibration effect is enhanced, the tone and the sound volume are significantly improved, and revolutionary changes of traditional vertical pianos and present vertical pianos occur.

Description

technical field [0001] The invention relates to a musical instrument, that is, a high-efficiency vibration upright piano capable of high-efficiency sounding in the high-pitched range. Background technique [0002] Both traditional and current upright pianos feature cast iron plates, also known as braces, steel plates, or bars. The upper part of the cast iron plate is provided with multiple pegs, the lower part is provided with hanging piles, and the lower part is provided with string nuts. The string nut is used to support the strings, so that the effective vibration part of the strings is kept at a certain distance from the cast iron plate. Such as figure 2 As shown, most of the existing string nuts are elongated ribs, and the cross section of the ribs, that is, the cross section along the string passing direction, is an equilateral triangle or an acute triangle. The strike point of the strings is gradually approaching the string nut from the middle range in the low rang...

Problems solved by technology

In addition, the air shock wave emitted by the string strike point directly acts on the root of the string nut and the inner slope, further reducing the vibration space on the back of the strike point, resulting in an extreme imbalance between the front and back vibration spaces of the strike point, and greatly reducing the vibration efficiency , the sound produced is small and blunt, which has a negative impact on the acoustics of the piano
