Abstract
The utility model relates to a special abnormal-shaped curve soundboard frame, which consists of a soundboard (1), an upper frame (3), a lower frame (5), a left frame (2) and a right frame (4), wherein the upper part of the upper frame (3) is connected with the soundboard (1); the lower part of the lower frame (5) is connected with the soundboard (1); the left side of the left frame (2) is connected with the soundboard (1); and the right side of the right frame (4) is connected with the soundboard (1). In the utility model, the resonance area of the soundboard opposite to mid-high string codesis large; according to the theory that the resonance oscillation stress field of the oscillation in different octaves is different, the resonance of the middle octave and the high octave is enhanced,so that the sound in the middle octave and the high octave can be more penetrable, and the tenuto is prolonged, thereby effectively solving the problem that the tenuto is short in the middle octave and the high octave.
Description
Technical field
The happy accessory of the utility model dominant field particularly relates to a kind of special special-shaped curve soundboard frame.
Background technology
Piano soundboard and stall bars are vitals of piano, its effect is that the vibrational energy that is inspired when the hammerhead of hammered string instrument knocks string is transferred to soundboard by the string sign indicating number, and the stall bars on the soundboard pass to vibration at each position of soundboard, cause the large tracts of land vibration of soundboard, thereby drive the soundboard ambient air and also participate in resonance, the faint sound of the script that string is sent obtains the increase of cube ratio by the effect of soundboard, the amplitude of soundboard is big more, and the sound that piano sent is also just got over magnanimity.The effect of stall bars is set on soundboard, the one, in order to strengthen the structural rigidity of soundboard, the 2nd, make soundboard obtain cambered surface, have elasticity, every stall bars all are processed into certain cambered surface, behind the soundboard gummed, make soundboard be dome shape.The 3rd, transmit transverse vibration, increase acoustics.
Existing piano is to utilize the soundboard frame that soundboard is fixed on the piano, stall bars are glued on the soundboard, the two ends of stall bars are provided with soft shoulder, soft shoulder all extend in the soundboard frame, by frame stall bars are killed, like this, though can avoid with the passing of time the come unstuck danger of raw edge of stall bars two ends, but reduced the vibration performance of soundboard, had influence on the acoustics of piano.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of special special-shaped curve soundboard frame, with the short problem of alt tenuto that solves piano.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of special special-shaped curve soundboard frame is provided, by soundboard, upper ledge, lower frame, left side frame and right frame are formed, and described upper ledge is connected with soundboard in top, and described lower frame is connected with soundboard in the bottom, described left frame is connected with soundboard in the left side, and described right frame is connected with soundboard in the right side.
Described left frame is wide at the top and narrow at the bottom.
The wide right side, a described lower frame left side is narrow.
Described upper ledge and right frame coupling part soundboard frame material hollow out to the inside.
Beneficial effect
It is big that the soundboard of the utility model alt string sign indicating number correspondence shakes area altogether, according to the different theory of resonance stress field of different ranges of sound vibration, the sympathetic response increase in alt district makes alt district sound have more penetrability, tenuto increases, and efficiently solves the short difficult problem of alt district tenuto.
Description of drawings
Fig. 1 is special special-shaped curve soundboard mount structure figure.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
A kind of special special-shaped curve soundboard frame, by soundboard 1, upper ledge 3, lower frame 5, left frame 2 and right frame 4 are formed, and described upper ledge 3 is connected with soundboard 1 in top, the lower frame 5 left wide right sides are narrow and be connected with soundboard 1 in the bottom, left side frame 2 is wide at the top and narrow at the bottom and be connected with soundboard 1 in the left side, and right frame 4 is connected with soundboard 1 in the right side, and upper ledge 3 and right frame 4 coupling part soundboard frame materials hollow out to the inside.When knocking key, alt district sound has more penetrability, and tenuto increases.
Claims (4)
