Abstract
The utility model discloses a string bridge for pianos, which comprises a string bridge body and bridge nails, and the center of the bottom of the string bridge body is provided with an arc-shaped notch. Both sides of the string bridge body of the string bridge are provided with two arc-shaped notches, which have the same size and are symmetrical at the left and the right. The string bridge has the advantages that: not only is the compression resistance of the string bridge guaranteed, but also the size of the string bridge is effectively reduced, and the loss of acoustic energy on the string bridge is reduced.
Description
Technical field
The utility model relates to the parts of piano, is specially the string sign indicating number of piano.
Background technology
The string sign indicating number of piano is an important component of piano resonance system, and it gives soundboard with the NE BY ENERGY TRANSFER of string vibration, and plays the effect that beautifies tonequality.In the musical instrument of all string vibrations, the string sign indicating number all has crucial influence to tone color, and it is that the shape of string sign indicating number, size and material all have direct influence to tone color with the medium of string vibration transfer to soundboard.The string sign indicating number is used the good hard wood of sound wave conduction more, and purpose is as much as possible the energy of string vibration to be passed to soundboard, drops to the loss of sound wave minimum.The volume of string sign indicating number is all less in other stringed musical instruments, and piano is because the tension force of string is very big, pressure to the string sign indicating number is very big, so the string sign indicating number of piano can not be little as the string sign indicating number of other stringed musical instruments, so so its volume is big can consume a lot of energy in the transmittance process of sound wave.If traditional string code system is decided and stressed material and manufacture craft at present, the volume to the string sign indicating number does not change.
Summary of the invention
The purpose of this utility model is exactly in order to solve the above problems, and a kind of string sign indicating number of piano is provided and has obtained useful effect.
In order to solve the problems of the technologies described above, the string sign indicating number of piano of the present utility model comprises string sign indicating number main body and flat nail, and flat nail is two rows, and per three is one group, and there is an arc groove center of string sign indicating number main body bottom surface.
The string sign indicating number of piano of the present utility model, there are two arc grooves the two sides of string sign indicating number main body, the identical left-right symmetric of two arc grooves size.
The beneficial effect that the utility model is obtained is: not only guaranteed the compressive property of string sign indicating number but also effectively reduced the volume of string sign indicating number, reduced the loss of acoustic wave energy on the string sign indicating number.
Description of drawings
Fig. 1 is a plan structure synoptic diagram of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of embodiment 1.
Fig. 3 is the A-A cross-sectional schematic of embodiment 2.
Among the figure: 1, string sign indicating number main body, 2, flat nail.
Embodiment
As depicted in figs. 1 and 2, the string sign indicating number of the piano of present embodiment comprises string sign indicating number main body 1 and flat nail 2, and flat nail 2 is two rows, per three be a winding on string sign indicating number main body 1, there is an arc groove center of string sign indicating number main body 1 bottom surface.So design can reduce the volume of string sign indicating number, and arc groove can be distributed to the pressure that is subjected to the various piece of string sign indicating number equably simultaneously, and stressed more reasonable, the strength of materials can be fully used.
As shown in figures 1 and 3, the string sign indicating number of the piano of present embodiment, there are two arc grooves the two sides of string sign indicating number main body 1, two identical left-right symmetric of arc groove size, other structures and usage and example example 1 are basic identical.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
Claims (2)
1. the string sign indicating number of piano comprises string sign indicating number main body (1) and flat nail (2), it is characterized in that: there is an arc groove center of described string sign indicating number main body (1) bottom surface.
2. the string sign indicating number of piano according to claim 1, there are two arc grooves the two sides of described string sign indicating number main body (1), two identical left-right symmetric of arc groove size.
