Abstract

A piano iron plate, a plurality of rows of concave point groups (2) are arranged on one surface of the piano iron plate (1) for hanging strings, each row of concave point groups (2) comprises a plurality of grooves (3) with different specifications, and the specifications comprise the transverse width, the longitudinal width, the depth and the opening radian of the grooves (3). As the surface of the piano iron plate (1) is uneven, when playing the piano, the reflection of sound is increased through a plurality of irregular grooves (3), further, the repeated reflection of string sounds is effectively increased to increase the volume, and the plumter tone is also obtained.

Description

Piano iron plate

Technical Field

The invention relates to the technical field of pianos, in particular to a piano iron plate.

Background

The piano iron plate is one of piano parts and is used for hanging strings, determining factors are given to the quality of the piano, when the surface of the existing piano iron plate is smooth and a piano is played, when the strings are repeatedly reflected to the surface of the iron plate, the surface of the iron plate is smooth, the reflection surface of sound is less, the volume is small, and the tone is thin.

Disclosure of Invention

Because the surface of piano iron plate is smooth, and sound reflection angle is few when playing the musical instrument, the problem that the volume is little and tone is single thin easily takes place, this application provides a piano iron plate, and a plurality of rows of concave point groups have been seted up to the one side that piano iron plate was used for hanging the string, and every row of concave point group includes the recess of a plurality of different specifications, and the specification includes the transverse width, the longitudinal width, the degree of depth and the opening radian of recess.

In one embodiment, there are at most two grooves of the same depth in the plurality of grooves of each row of pit groups.

In one embodiment, the longitudinal width of the groove is 4.3mm-12.4mm, the transverse width of the groove is 11.4mm-18mm, the depth of the groove is 0.4-1.9mm, and the opening radian of the groove is 3.6-10 degrees.

In one embodiment, the spacing between the centers of adjacent rows of pit sets is 9mm-9.9mm in the plurality of rows of pit sets.

According to the piano iron plate of the embodiment, as the plurality of rows of concave point groups are formed in one surface of the piano iron plate for hanging strings, each row of concave point groups comprises a plurality of grooves with different specifications, when the piano iron plate is played, the reflection of sound is increased through the plurality of irregular grooves, further, the repeated reflection of string sounds is effectively increased, the volume is increased, and the plumter tone is also obtained.

Detailed Description

The invention will be described in further detail below with reference to the drawings by means of specific embodiments.

In the embodiment of the invention, a plurality of irregular pits are designed on one surface of the piano iron plate for hanging strings, so that the reflection of sound is increased, the volume is increased, and a full tone is obtained.

The piano iron plate is shown in fig. 1, wherein a plurality of rows of concave point groups 2 are formed on one surface of the piano iron plate 1 for hanging strings, each row of concave point groups 2 comprises a plurality of grooves 3 with different specifications, and the specifications comprise the transverse width, the longitudinal width, the depth and the opening radian of the grooves 3.

Specifically, according to actual needs, a plurality of rows of concave point groups 2 can be partially or completely formed on one surface of the piano iron plate string, in this example, only a plurality of rows of concave point groups 2 are partially formed, at most two grooves 3 with the same depth are formed in a plurality of grooves 3 in each row of concave point groups 2, more preferably, two grooves 3 with the same depth are formed in each 120mm length of each row of concave point groups 2, and a schematic structural diagram of the concave point groups 2 is shown in fig. 2.

The specifications of the grooves 3 in each row of pit groups 2 are different, and the specific specifications of the grooves 3 are as follows: the longitudinal width of the groove 3 is 4.3mm-12.4mm, the transverse width of the groove 3 is 11.4mm-18mm, the depth of the groove 3 is 0.4-1.9mm, the radian of the opening of the groove 3 is 3.6-10 degrees, and the spacing between the centers of adjacent rows of concave point groups 2 in the plurality of rows of concave point groups 2 is 9mm-9.9mm, and a specific partial enlarged view is shown in fig. 3.

Specifically, because the chord tone reflection effect is different, the piano iron plate surface needs to be equipped with the recess 3 of the sound reflection angle of different specifications, take recess 3 that has multiple different specifications in the recess group 2 of a line as an example, according to the needs of chord tone reflection effect, can design the specification of recess 3 as: the longitudinal width of the groove 3 is 4.3mm, 4.5mm, 5.8mm, 12.4mm and the like; the transverse width of the groove 3 is 11.4mm, 11.6mm, 15.8mm, 18mm and the like; the depth of the groove 3 is 0.4mm, 0.5mm, 0.8mm, 1.9mm and the like; the radian of the opening of the groove 3 is 3.6 degrees, 3.8 degrees, 8.6 degrees, 10 degrees and the like; and the distances between the centers of the concave point groups 2 of adjacent rows on the surface of the piano iron plate are 9mm, 9.3mm, 9.5mm, 9.9mm and the like.

Because the one side of the piano iron plate string of this application has seted up a plurality of rows of pit group 2, every row of pit group 2 includes the recess 3 of a plurality of different specifications for piano iron plate surface is unsmooth, when playing the musical instrument, in the recess 3 was reflected repeatedly to the string sound, the sound reflection was increased to a plurality of irregular recess 3, the reflection of sound can effectively be increased to the piano iron plate of this application, increases the volume, also obtains more full tone.

The foregoing description of the invention has been presented for purposes of illustration and description, and is not intended to be limiting. Several simple deductions, modifications or substitutions may also be made by a person skilled in the art to which the invention pertains, based on the idea of the invention.
