Abstract
The utility model discloses a piano acoustic panel which comprises a back frame and an acoustic panel, wherein the acoustic panel is a right-angled trapezoid acoustic panel whose lower side is a right-angle side, one side of an acoustic back frame is felted with a plurality of inclined bars, the left side, the upper side and the right side of the acoustic panel are felted on the framework of the back frame through a left acoustic panel frame, an upper acoustic panel frame and a right acoustic panel frame, the lower side of one side of the acoustic panel back frame is felted with a cross bar, and gaps are left between a plurality of inclined bars, a cross bar and the back frame. The middle portion and the lower side of the acoustic panel and the back frame are suspended, the vibration range of the acoustic panel is increased, the gamut is wider, the volume is fully played, sound is prolonged, and acoustic fidelity and acoustic quality are more beautiful.
Description
Technical field
The utility model relates to the piano technical field, especially a kind of piano soundboard of upright piano.
Background technology
In the prior art, the soundboard of upright piano comprises back of the body frame, soundboard frame and soundboard, and the soundboard of right-angled trapezium is fixed on the back of the body frame by four soundboard frames at soundboard edge, the stall bars of many inclinations of bonding on the soundboard in the soundboard frame.It is little that the soundboard of this structure exists vibration amplitude, and range is narrow, and volume can not fully obtain performance.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, vibration amplitude is big, range is wide, tenuto is long, sound quality is graceful piano soundboard is provided.
The purpose of this utility model is achieved in that a kind of piano soundboard, comprise back of the body frame and soundboard, described soundboard is the following right-angled trapezium soundboard of right-angle side that is, many inclination stall bars of soundboard back of the body frame one side bonding, it is characterized in that: the left side of soundboard, top and the right are bonded on the frame of back of the body frame by left soundboard frame, upper sounding board frame and right soundboard frame successively; Leave the gap between cross rib wood of the following bonding of soundboard back of the body frame one side, many inclination stall bars and cross rib wood and back of the body frame, make the middle part of soundboard and following and carry on the back between the frame and be in vacant state.
As prioritization scheme of the present utility model, the two ends of described cross rib wood and inclination stall bars all are the chip shape of arc transition, and the thickness of thin slice is 1/4～1/2 of its interior thickness.
Described inclination stall bars are ten.
The utility model compared with prior art has following advantage: be in vacant state between the middle part of the utility model soundboard and following and the back of the body frame, increased the vibration amplitude of soundboard, its range is more wide, and volume is not fully exerted, and tenuto is long, and sound quality is graceful more.
Description of drawings
Fig. 1 is the utility model piano soundboard deployed condition perspective view;
Fig. 2 is the utility model soundboard frame, cross rib wood and inclined ribs body structure synoptic diagram of standing motionless.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
As shown in Figure 1, a kind of piano soundboard, comprise back of the body frame 1 and soundboard 7, described soundboard 7 is the following right-angled trapezium soundboards of right-angle side that are, ten inclination stall bars 5 of soundboard 7 back of the body frame 1 one sides bondings, the left side of soundboard, top and the right are bonded on the frame of back of the body frame 1 by left soundboard frame 3, upper sounding board frame 2 and right soundboard frame 4 successively; Leave the gap between cross rib wood 6 of the following bonding of soundboard 7 back of the body framves 1 one sides, many inclination stall bars 5 and cross ribs wood 6 and back of the body frame 1, make the middle part of soundboard 7 and following and carry on the back between the frame 1 and be in vacant state.As shown in Figure 2, the two ends of described cross rib wood 6 and inclination stall bars 5 all are the chip shape of arc transition, and the thickness of thin slice is 1/3 of its interior thickness.
