Abstract
The utility model discloses a grand piano soundboard, comprising a cover plate and a back frame, wherein the front side, the left side and the right side of the cover plate are respectively bonded with the back frame in a closed manner; the lower side of the cover plate is bonded with inclined wall bars which are contacted with the back frame; the back frame consists of an outer ring and a soundboard frame arranged at the inner side of the outer ring; the rear part of the cover plate and the rear part of the outer ring are all arc-shaped and correspond to each other; the rear part of the outer ring is provided with a concave opening; the lower side of the rear part of the cover plate is bonded with an arc-shaped wall bar corresponding to the concave opening; and a gap is left between the arc-shaped wall bar and the concave opening. In the grand piano soundboard, due to no contact between the arc-shaped wall bar and the concave opening, the cover plate and the outer ring are in suspended state, so that the vibration of the soundboard is greatly increased, the sound range is also wider, the sound volume is completely played, the delayed sound is lasting and the tone color is more beautiful.
Description
Technical field
The utility model relates to the piano technical field, especially a kind of grand piano soundboard.
Background technology
In the prior art, the grand piano soundboard comprises cover plate and back of the body frame, all glued joint with the sealing of back of the body frame on the front side of described cover plate, left side, right side, the downside of cover plate glueds joint cant timber, cant timber touches with back of the body bridge joint, back of the body frame is made of outer ring and the soundboard frame that is arranged at the inboard, outer ring, and the rear portion of cover plate and the rear portion of outer ring are circular arc, and the rear portion of cover plate is corresponding mutually with the rear portion of outer ring.
Yet the range of the grand piano soundboard of prior art, tenuto length, sound quality await further to strengthen, and its volume can not be brought into play fully.
Summary of the invention
In order to overcome defective of the prior art, the purpose of this utility model is to provide a kind of novel trigon piano soundboard, and this trigon piano soundboard range is more wide, tenuto is longer, and volume is bigger, and sound quality is graceful more, this trigon piano soundboard is simple in structure simultaneously, is easy to processing.
The purpose of this utility model is achieved in that a kind of grand piano soundboard, comprise cover plate and back of the body frame, the front side of described cover plate, the left side, all glued joint with the sealing of back of the body frame on the right side, the downside of described cover plate glueds joint cant timber, described cant timber and described back of the body bridge joint touch, described back of the body frame is made of outer ring and the soundboard frame that is arranged at the inboard, outer ring, the rear portion of described cover plate and the rear portion of described outer ring are circular arc, and the rear portion of described cover plate is corresponding mutually with the rear portion of described outer ring, it is characterized in that: the rear portion of described outer ring is provided with recess, the downside at the rear portion of described cover plate glueds joint corresponding to described recess the arc stall bars, and leaves the gap between these arc stall bars and the described recess.
Gap between described arc stall bars and the described recess is 50-60mm.
The rear portion of described cover plate is provided with connector, and described arcuate rib wood glue is connected to described connector.
Described connector cuts down the connection breach that 10-15mm forms for the rear portion with cover plate.
The utility model compared with prior art has following advantage: in grand piano soundboard of the present utility model, the rear portion of cover plate and the rear portion of outer ring are circular arc, the downside at the rear portion of cover plate glueds joint the arc stall bars, the rear portion of outer ring is provided with recess, and leave the gap between the recess at the arc stall bars at the rear portion of cover plate and the rear portion of outer ring, the arc stall bars do not contact with recess, cover plate and outer ring are in half vacant state, this structure has strengthened the vibration amplitude of soundboard, and its range is more wide, and volume is brought into play fully, and back tenuto is permanent, tone color is graceful more, and this trigon piano soundboard is simple in structure simultaneously, is easy to processing.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of grand piano soundboard of the present utility model;
In Fig. 1
Embodiment
Below in conjunction with accompanying drawing grand piano soundboard of the present utility model is described further.
As shown in Figure 1, a kind of grand piano soundboard, comprise cover plate 1 and back of the body frame, the front side of cover plate 1, the left side, all glued joint with the sealing of back of the body frame on the right side, the downside of cover plate 1 glueds joint cant timber 3, this cant timber 3 touches with back of the body bridge joint, back of the body frame is made of outer ring 5 and the soundboard frame 6 that is arranged at 5 inboards, outer ring, the rear portion of the rear portion of cover plate 1 and outer ring 5 is circular arc, and the rear portion of cover plate 1 is corresponding mutually with the rear portion of outer ring 5, the rear portion of outer ring 5 is provided with recess 4, and the downside at the rear portion of cover plate 1 glueds joint corresponding to recess 4 arc stall bars 2, and leaves the gap between these arc stall bars 2 and the recess 4.
As embodiment more preferably, the gap between arc stall bars 2 and the recess 4 is 50-60mm.
In the utility model, the rear portion of cover plate 1 is provided with connector, and arc stall bars 2 glued joint in connector.Above-mentioned connector cuts down the connection breach that 10-15mm forms for the rear portion with cover plate 1.This connector can intercept at back 1/4 place of cover plate 1 integral body, and back 1/4 place of 5 integral body intercepts recess 4 in the outer ring.
Because the arc stall bars 2 in the utility model do not contact with recess 4, cover plate 1 is in half vacant state with outer ring 5, makes the vibration amplitude of soundboard increase greatly, its range is also more wide, volume is brought into play fully, and the back tenuto is permanent, and tone color is graceful more.
Above content only is a preferred embodiment of the utility model; unintelligible is qualification to the utility model protection domain; substitute or simple modification according to embodiment of the present utility model being equal to of doing for the technical work personnel of this area, should think and drop in the protection domain of the present utility model.
