Abstract
The utility model relates to a piano sound board skeleton frame and a sound frame having the same. The sound board skeleton frame comprises two horizontal frame bars and two vertical frame bars, and is characterized in that: the two horizontal frame bars bend slightly in the same horizontal direction; the two vertical frame bars bend slightly in the same vertical direction; after being arranged to form the sound board skeleton frame, the four frame bars bend slightly in the same direction; the length of straight lines between the middle point of each horizontal frame bar and two end points of the horizontal frame bar is 8 to 15 millimeters; the length of the straight lines between the middle point of each vertical frame bar and the two end points of the vertical frame bar is 3 to 6 millimeters; and the inner sides of both the horizontal frame bars and the vertical frame bars are provided with a plurality of holes. The special structural design of the sound board skeleton frame of the utility model enables a sound board to generate a better resonance effect and a stable and permanent sound quality. The piano sound board skeleton frame and the sound frame belong to the technical field of piano manufacturing.
Description
Technical field
The utility model relates to a kind of soundboard frame, soundboard framework, belongs to piano manufacturing technology field.
Background technology
Soundboard is the vitals of piano, and hammered string instrument knocks and passes in audience's ear after sound that string produces is empathized by soundboard.Traditional piano soundboard frame is prevailing structure in design, and 4 mouldings forming soundboard all are straight; The soundboard frame is with combine after soundboard installs must be just relatively closely, and the resistance during the soundboard vibration is bigger like this, and it is just poor to produce the effect that resonates.The patent No. is the structure that 200620045789.3 Chinese patent discloses a kind of piano soundboard resonance system, leave the gap between its soundboard and the soundboard frame, though the technical barrier that this has solved the resonance effect difference to a great extent, what bring is exactly unstable noise and the insecure problem of quality of easily producing of tonequality thereupon.
The utility model content
The purpose of this utility model provides a kind of piano soundboard framework.It has the advantage that can make soundboard play better resonance effect and more stable tonequality.
The above-mentioned technical purpose of a kind of piano soundboard framework of the utility model is achieved by the following technical programs:
A kind of piano soundboard framework, comprise two horizontal mouldings and two stiles, it is characterized in that: described two horizontal mouldings are identical all slight curving in a lateral direction, two stiles are all slight curving on identical vertical direction, four mouldings are mounted to behind the soundboard framework slight curving towards same direction, the distance that the mid point of described horizontal moulding leaves the straight line of described horizontal moulding two-end-point formation is 8～15mm, the distance that the mid point of described stile leaves the straight line that described stile two-end-point forms is 3～6mm, and all there are some holes described horizontal moulding and stile inboard.
The technical characterstic that the utility model transom bar is slight curving has solved the problem of soundboard resonance effect difference well, after it and back of the body frame and piano iron plate combine, bending slightly just is driven plain, and looks like this to be as good as in appearance with traditional piano soundboard frame.By after glue and the screw retention, the tonequality instability of soundboard, the insecure problem of quality are also solved thereupon again.
As preferably, the distance that the mid point of described horizontal moulding leaves the straight line that described horizontal moulding two-end-point forms is 9～13mm, and the distance that the mid point of described stile leaves the straight line that described stile two-end-point forms is 3～5mm.
As preferably, the distance that the mid point of described horizontal moulding leaves the straight line that described horizontal moulding two-end-point forms is 9mm, and the distance that the mid point of described stile leaves the straight line that described stile two-end-point forms is 3mm.
Another purpose of the present utility model provides a kind of soundboard frame, comprise soundboard, be fixed on the stall bars and the soundboard framework at the soundboard back side, it is characterized in that: described soundboard framework comprises two horizontal mouldings and two stiles, described two horizontal mouldings are identical all slight curving in a lateral direction, two stiles are all slight curving on identical vertical direction, four mouldings are mounted to behind the soundboard framework slight curving towards same direction, the distance that the mid point of described horizontal moulding leaves the straight line of described horizontal moulding two-end-point formation is 8～15mm, the distance that the mid point of described stile leaves the straight line that described stile two-end-point forms is 3～6mm, and all there are some holes described horizontal moulding and stile inboard; Described horizontal moulding is slight curving on described soundboard direction, and two vertical mouldings are slight curving on the soundboard direction.
As preferably, described stall bars are slight curving towards soundboard; The stall bars two ends are inserted in the hole of described soundboard framework, and arranged askew is glued on the soundboard.
In sum, the utlity model has following beneficial effect:
1, the design of the special construction of the utility model soundboard framework makes soundboard can play better resonance effect;
2, the design of the special construction of the utility model soundboard frame can access more stable purer tonequality after making soundboard resonate.
