Abstract

The utility model discloses a metal tone tuning plate of a piano. Due to the good physical stability of metal materials, the sense of pitch of the piano is more persistent, and the service life of the piano is prolonged to hundreds of years. The tone tuning plate cannot be easily abraded, rotted and deformed; the high structural stability of the tone tuning plate greatly improves the stability of the sense of pitch; in addition, the maintenance of the tone tuning plate is simple as well as convenient, and parts are convenient for replacing. The metal tone tuning plate is composed of an iron plate 9 and a movement adjusting part which is fixed on the iron plate 9 by a screw 8. The characteristics of the metal tone tuning plate are as follows: the movement adjusting part comprises an inverted n-shaped metal fixed rack 7 and an L-type metal tone tuning lever 4; a through groove where the tone tuning lever 4 can be inserted is arranged below and at one side edge of the fixed rack 7, the tone tuning lever 4 is connected with the fixed rack by a shaft 5, a screw through hole 6 is arranged above one side edge of the fixed rack, a pitch adjusting screw 1 is jacked on one border of the tone tuning lever after being screwed in, a piano string penetrating hole 2 is arranged at the end part of the other border of the tone tuning lever, and a screw hole of a piano string top thread 3 is arranged on the other surface vertical to one surface with the piano string penetrating hole 2.

Description

Piano metal toning board

(1) technical field

The utility model belongs to a kind of musical instrument fitting, and the toning board that specifically a kind of piano is used also can be used for various stringed musical instruments.

(2) background technology

Piano has been that raw material is made string shaft with hardwood since being born always, relies on friction force to come fastening peg to reach the adjustment string.The distortion easy to wear of this traditional structure, structure are stable inadequately, and anti-vibration resistance is bad, accuracy in pitch stable bad.

(3) summary of the invention

The utility model purpose is to disclose a kind of piano metal toning board, is to be grouped into by iron plate 9 and motion adjusting portion, and motion adjusting portion lease making screw 8 is fixed on the iron plate 9.It is characterized in that: motion adjusting portion branch comprises metal fixed mount 7 and L type metal tuning lever 4 that a n falls shape, the below of fixed mount 7 and a side have the groove that can insert tuning lever 4, tuning lever 4 is connected with fixed mount by axle 5, fixed mount one side top has screw through-hole 6, after being screwed into, pitch adjusting screw 1 pushes up on the frame of tuning lever, another frame end of tuning lever, have string perforation 2, having on string perforation 2 another vertical plane simultaneously has a screw that string jackscrew 3 is housed.

The utility model utilizes the good physical stability of metal material to make the piano accuracy in pitch more lasting, and the life-span is brought up to a century.Toning board is not easy to wear to rot, and not yielding, Stability Analysis of Structures improves accuracy in pitch stability greatly, easy maintenance, and renewal part is convenient, is unlikely to abandon whole string shaft even whole piano because of local problem.
