Abstract
The invention relates to a sound source structure for a piano. The sound source structure mainly comprises a code bridge and a soundboard. The sound source structure is characterized in that the code bridge is provided with strings and a phoenix bridge crossing structure. When the sound source structure is used, the phoenix bridge crossing structure is used on the code bridge; the strings are arranged in a metal member and form an upward tension force by the phoenix bridge crossing structure so as to reduce the pressure on the sound source soundboard caused by the low-sound strings. Compared with the prior art, the structure has the advantages that the pressure on the soundboard, caused by the improved low-sound strings, is reduced by one third, so that the soundboard of the piano is sufficiently vibrated and a sound source of the piano can be expressed incisively and vividly; the sound source structure has loud and clear tones and is long-standing and well-established.
Description
Technical field
The present invention relates to the technical field of piano, specifically a kind of sound source structure for piano.
Background technology
Currently, the string flat nail using on all commonly used bridge in code both at home and abroad, steel wire can form one at string flat nail
Angle, steel wire has a downward pressure to reach sounding, such as Application No. " CN201220656303.5 " when string code,
The application documents of entitled " upright piano acoustic source system structure ", describe a kind of such technical scheme " upright piano source of sound
System structure, including ferrum row, string, peg nail, string shaft, soundboard, stall bars and Ma Qiao, 218 peg nails are separately fixed at string
On axillare, capotasto includes capotasto on high pitch, high pitch lower chord pillow, capotasto, middle pitch lower chord pillow I, middle pitch lower chord pillow II, bass on middle pitch
Upper capotasto, code bridge includes alt area code bridge and bass area Ma Qiao, alt area code bridge and bass area code bridge is provided with altogether up and down
Two nails, one end of string is fixed on peg and nails on, and the other end is fixed on ferrum row's lower edge and nails on, and key label 1 is to key mark
Numbers No. 30 corresponding pegs nails are located at bass area, and key label 31 is located at middle pitch to No. 58 corresponding pegs nails of key label
Area, key label 59 is located at treble to No. 88 corresponding peg nails of key label." but above-mentioned traditional structure and production are installed
Processing technique, to produce piano sound source, because pronunciation board vibration frequency is limited, makes the sounding of piano cannot discharge completely, limit
Make the tone color of piano.
Content of the invention
It is an object of the invention to provide a kind of improved sound source structure for piano, it can overcome in prior art by
Limited in pronunciation board vibration frequency, so that the sounding of piano cannot be discharged completely, limit some shortcomings of the tone color of piano.
To achieve these goals, the technical scheme is that：A kind of sound source structure for piano, it mainly includes
Code bridge and soundboard it is characterised in that：Code bridge is provided with string code and string, and string passes through phoenix bridge structure with string code-phase even, institute
The phoenix bridge structure stated is provided with phoenix support, and described string is set up on phoenix support.
During use, the present invention employs phoenix bridge structure on code bridge, and string is arranged in hardware, string warp
Cross phoenix bridge structure and form a pulling force upwards, it is possible to reduce bass string is to pressure produced by sound source soundboard, and existing
Technology is had to compare, the bass string after improvement decreases 1/3rd to the pressure of soundboard, so that the soundboard of piano is obtained more abundant
Vibrations so that piano sound generation source can perform to incisively and vividly, tone color is loud and clear, of long standing and well established.
Brief description
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structural representation of phoenix bridge structure of the present invention.
Fig. 3 is the structural representation of phoenix support of the present invention.
Fig. 4 is the structural representation of string fixing axle of the present invention.
Fig. 5 customizes the structural representation of screw for the present invention.
Fig. 6 customizes the structural representation of nut for the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Label in each accompanying drawing is expressed as follows：1 yard of bridge, 2 soundboards, 3 string codes, 4 strings, 5 phoenix bridge structures, 6 phoenix prop up
Frame, 7 string fixing axles, 8 customization screws, 9 customization nuts, 10 buckles, 11 arc fulcrums, 12 locating slots.
A kind of sound source structure for piano of the present invention, it mainly includes yard bridge and soundboard, itself and prior art
Difference be：Code bridge is provided with string code and string, and string passes through phoenix bridge structure with string code-phase even, and described phoenix passes a bridge
Structure is provided with phoenix support, and described string is set up on phoenix support.Phoenix bridge structure includes phoenix support, string is fixed
Axle, customization screw and customization nut are constituted, and customization screw is fixed on string code, and phoenix support passes through to customize nut and customization screw
It is fixedly connected on string code.Code bridge includes alt area string code and bass area string code, and code bridge is arranged on soundboard.Described here
Customization screw and customization nut are screw and the nut that size passes through customization, its 26S Proteasome Structure and Function and existing screw, nut
Essentially identical, just repeat no more its operation principle and structure here.
Phoenix support is formed with snapping connection by support, and the two ends made are provided with the arc fulcrum of projection, and buckle is arranged at
The top of support, is provided with string fixing axle in buckle, described string is arranged in buckle and is carried out by string fixing axle solid
Fixed.The centre of string fixing axle is provided with locating slot, and described locating slot size is matched with the size of string.Described buckle is
Hardware, buckle is in hook solid.
In force, by bass area string code punching template in string code surface drilling, customization screw is positioned in boring, so
Afterwards phoenix is propped up and be placed on string code, phoenix support opens up fixing hole, the size of fixing hole and the size phase customizing nut
Join, be connected so that phoenix support is fixed on string code by customizing nut with customization screw, wherein customization nut needs to use
Installation tool is beaten, so that it is connected with customization fastened by screw.Then string is placed in the buckle of phoenix support, by string
String is relatively fixed in buckle fixing axle, and adjustment chord position makes it be completely disposed in the locating slot of string fixing axle, then
The two ends of string are separately fixed on the bail of iron plate, tension string can complete to install.
Due to employing phoenix bridge structure on code bridge, string is arranged in the buckle of phoenix support, because phoenix props up
Set up and have the fulcrum of two arcs, string fixing axle turns pushes down string, change whole piece string to the pressure of string code and soundboard so that
String is formed for a pulling force upwards after phoenix bridge structure, it is possible to reduce bass string is to produced by sound source soundboard
Pressure, compared with prior art, the bass string after improvement decreases 1/3rd to the pressure of soundboard, makes piano when playing
Soundboard is more fully shaken so that piano sound generation source can perform to incisively and vividly, and tone color is loud and clear, of long standing and well established.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
Member, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be regarded as
Protection scope of the present invention.
