Abstract

The utility model relates to a piano equipment technical field, especially a be applied to novel string sign indicating number that has two hole open groove structures on piano, compare with prior art, this novel string sign indicating number that has two hole open groove structures adopts two hole open groove structural design, has increased the part fretwork of string sign indicating number zhongtongdao, can effectively increase soundboard vibration area, improves the conductivity of string sign indicating number, and the energy that makes string sign indicating number vibration produce can transmit for the soundboard rapidly to the sound that makes the soundboard send is more penetrating.

Description

Novel string sign indicating number with two hole fluting structures

Technical Field

The invention relates to the technical field of piano equipment, in particular to a novel string code with a two-hole slotting structure, which is applied to a piano.

Background

The piano string sign indicating number among the prior art generally adopts the wood to carry out the whole strip and fixes on the soundboard, adopts having of this kind of structure simple to operate, technology is few, and manufacturing cost is lower, adopts the sectional type in addition, for example the chinese patent publication number that has disclosed is: CN206726743U, name: a utility model patent for a sectional type zhongyin district string sign indicating number of piano, its string sign indicating number adopt one section to carry out the structural design of sectional type, adopt this kind of connection structure on the one hand that mounting process is more complicated, and on the other hand is that stability is good inadequately, takes place to remove easily and the position is inclined to one side, influences tone quality.

Disclosure of Invention

In order to solve the defects and problems of the back frame of the piano in the prior art, a novel string code with a two-hole slotting structure is provided.

The technical scheme adopted by the invention for solving the technical problem is as follows: the novel string code with the two-hole slotting structure comprises a sound board, wherein the string code is fixed on the sound board, one end of the string code extends inwards to a transverse plate on the sound board, the other end of the string code extends outwards in a curve, an inner groove is milled at the bottom of the end, extending outwards in a curve, of the string code, the inner grooves are distributed on two sides of the string code, two through holes are formed in the inner grooves, and the end, extending outwards in a curve, of the string code forms a hollowed-out structure.

The two through holes are in a strip-shaped structure.

The string code is in curve distribution and is distributed towards the outer end of the soundboard in a curve shape.

The invention has the beneficial effects that: compared with the prior art, the novel string code with the two-hole slotted structure adopts the two-hole slotted structure design, the partial hollow of the sound section in the string code is increased, the vibration area of the sound board can be effectively increased, the conductivity of the string code is improved, the energy generated by the vibration of the string code can be rapidly transmitted to the sound board, and therefore the sound emitted by the sound board is more transparent.

Drawings

The novel string bridge with a two-hole slotted structure of the invention is further described below with reference to the accompanying drawings and the detailed description.

Fig. 1 is a schematic perspective view of the novel string bridge with a two-hole slotted structure according to the present invention.

The specific implementation mode is as follows:

as shown in fig. 1, the novel bridge with a two-hole slotted structure of the present invention comprises a soundboard 10, and a transverse plate 11 is provided at the rear end of the soundboard 10. A bridge 20 is fixed to the sound board 10, the bridge 20 is fixed to the sound board 10, and one end of the bridge 20 extends inward toward the lateral plate 11 of the sound board 10, but the bridge 20 is not connected to the lateral plate 11 of the sound board 10. The other end of the string code 20 extends outwards in a curve, and the string codes 20 are distributed in a curve shape and distributed towards the outer end of the soundboard 10 in a curve shape.

As shown in fig. 1, an inner groove 21 is milled at the bottom of the outwardly curved end of the code 20. The inner grooves 21 are distributed on two sides of the string code 20, two through holes 22 are formed in the inner grooves 21, the two through holes 22 are of long strip-shaped structures, and the two through holes 22 enable one end of the string code 20, extending outwards in a curve, to form a hollow structure. This kind of hollow out construction can effectively increase soundboard vibration area, improves the conductivity of string sign indicating number, and the energy that makes string sign indicating number vibration produce can transmit for the soundboard rapidly to the sound that makes the soundboard send is more penetrating.

In conclusion, compared with the prior art, the novel string code with the two-hole slotted structure adopts the two-hole slotted structure design, the partial hollow of the sound segment in the string code is increased, the vibration area of the sound board can be effectively increased, the conductivity of the string code is improved, the energy generated by the vibration of the string code can be rapidly transmitted to the sound board, and therefore the sound emitted by the sound board is more transparent.

The present invention has been described in accordance with embodiments thereof with the understanding that the present invention is not limited thereto but rather it is to be understood that variations and/or modifications may be made by those skilled in the art without departing from the scope of the invention as defined by the appended claims, and any such modifications, equivalents and the like as fall within the true spirit and scope of the invention.

Claims

1. Novel string sign indicating number with two hole fluting structures, its characterized in that: including the soundboard, the string sign indicating number is fixed on the soundboard, and string sign indicating number one end is inwards to a diaphragm department on the soundboard and extends, and the string sign indicating number other end outwards is curve extension, is curve extension one end bottom outwards at the string sign indicating number and is milled an inner groovy, the inner groovy distributed in the both sides of string sign indicating number, be equipped with two through-holes on the inner groovy, make outwards being curve extension one end of string sign indicating number form a hollow out construction.

2. The novel bridge with two-hole slotted structure of claim 1, wherein: the two through holes are in a strip-shaped structure.
