Abstract
The utility model discloses a dulcimer sound beam and relates to a dulcimer component. The dulcimer sound beam comprises a sound beam body. The top side of the sound beam body is provided with at least two first vent holes whose cross sections are semicircular. The dulcimer sound beam is characterized in that the sound beam body is further provided with at least one second vent holes whose cross sections are circular; the second vent holes are located between the first vent holes and the bottom side of the sound beam body; and the tops of two sides located on two sides of the top side of the sound beam body contracts inward, so that the top of the cross section of the sound beam body is trapezoid. Compared with the prior art, the dulcimer sound beam provided by the utility model has the advantages that second vent holes are added on the sound beam body; the top of the cross section of the sound beam body is trapezoid; the vibration of the sound beam is stronger; the resonance is greatly improved; and the structure is especially suitable for the sound beam which is located below a high pitch code and is corresponding to the high pitch code.
Description
Technical field
The utility model relates to a kind of parts of dulcimer, more specifically to a kind of sound beam of dulcimer.
Background technology
Existing dulcimer structure, comprise qin body, string, numeral, be provided with resonant tank in the described qin body, described resonant tank comprises panel, front side board, back side panel, base plate and sound beam, panel, front side board, back side panel, base plate form casing, the rear and front end of sound beam connects respectively front side board, back side panel, the top of sound beam props up the bottom surface of panel, have at least one air hole between the left and right side of described sound beam, numeral is located on the panel end face of qin body, string is pressed on the numeral, and the two ends of string are fixed on the panel end face of qin body.
Described sound beam is usually corresponding one by one with numeral, and namely number is identical, and lays respectively at the up and down both sides of the panel of qin body, but the sound beam is not positioned under the numeral, so it is bad to support the effect of panel of qin body.Like this, the sound beam can not be cancelled out each other to the pressure of the panel of qin body fully to anchorage force and the numeral of the panel of qin body, and the pressure that the panel of qin body is subject to is larger, easily deforms or damages.
Because the sympathetic response effect of resonant tank is relatively poor, therefore in order to obtain preferably sympathetic response effect, resonant tank need to design greatlyr, so the qin body must have enough width.And the length of string need to adapt with the qin body, so the length of string is also long.So long string, if larger with the diameter design of string, string just is easy to fracture, therefore can only be with the diameter design of string smaller.Therefore but the string of minor diameter can't send enough large sound, and the number needs of corresponding string wants a lot of on numeral, just can send enough large volume.
Therefore, the traditional dulcimer of above-mentioned this structure, its complex structure, manufacturing bother, keep in repair very difficult very much, and its volume is very large, Heavy Weight, is difficult to carry.
In order to address the above problem, the applicant improves the structure of dulcimer, and applied for utility model patent, the patent No. is CN201120048648.8, name is called " a kind of Novel dulcimer structure ", it comprises the qin body, be provided with resonant tank in the qin body, described resonant tank comprises panel, front side board, back side panel, base plate and sound beam, panel, front side board, back side panel, base plate forms casing, and the rear and front end of sound beam connects respectively front side board, back side panel, the top of sound beam props up the bottom surface of panel, have at least one air hole between the left and right side of described sound beam, it is characterized in that: described air hole is positioned at the junction, bottom surface of sound back end and panel.
In the scheme of above-mentioned utility model patent, the applicant mainly improves the structure of sound beam, the position of air hole has been moved to the top from the middle part of sound beam, the improvement of this structure is so that the sympathetic response effect of dulcimer has obtained significantly improvement, and the volume of resonant tank can significantly reduce, and the width of qin body also can significantly shorten.
But the applicant found through experiments the dulcimer that adopts above-mentioned this dulcimer structure, and the tone color of high pitch is good not.The applicant scrutinizes rear discovery, and this is because when the player knocks the string that is positioned on the high tone code, and the sound beam vibration corresponding with high tone code that is positioned at high tone code below is strong not, and sympathetic response is good not.
Summary of the invention
Technical problem to be solved in the utility model is strong not for the prior art sound beam vibration corresponding with high tone code, and the imperfect shortcoming of sympathetic response provides a kind of sound beam of dulcimer, and the sound beam vibration of this dulcimer is stronger, and sympathetic response significantly promotes.The technical scheme that adopts is as follows:
A kind of sound beam of dulcimer, comprise sound beam body, described sound beam body top margin has the first air hole of at least two xsect semicirculars in shape, it is characterized in that: described sound beam body also has the second rounded air hole of at least one xsect, and described the second air hole is between first air hole and base of sound beam body.
More excellent scheme, described sound beam body base has the 3rd air hole of at least two xsect semicirculars in shape.
More excellent scheme, the number of described the 3rd air hole is identical with the number of the first air hole, and both are corresponding one by one, any one vertical with sound beam body top margin and through the straight line in the first air hole center of circle, this straight line must be through the 3rd air hole center of circle.
More excellent scheme, described the first air hole vertically is arranged in order along sound beam body, and the spacing of any two the first adjacent air holes is identical.
More excellent scheme, the spacing of described two the first adjacent air holes is greater than the internal diameter of the second air hole.
More excellent scheme, any one vertical with sound beam body top margin and through the straight line of the first air hole, the distance of this straight line and the second air hole is greater than 0.That is to say, any one second air hole can not be positioned on the straight line vertical with sound beam body top margin with any one first air hole, can avoid like this intensity of sound beam body to decline to a great extent, and in use is not easy to damage.
In order further to improve the sympathetic response of sound beam, inwardly shrink at the top that described sound beam body is positioned at two sides of top margin both sides, so that being shaped as of sound beam body cross-section top is trapezoidal.Like this, guaranteeing that sound beam body has under the prerequisite of adequate thickness and intensity, the contact area of described sound back end and panel is less, and is convenient to the sound vibration of beam, promotes the sympathetic response of sound beam.
More excellent scheme, described two trapezoidal hypotenuses are outwardly camber line.
More excellent scheme, described the second air hole to the distance of the top margin of sound beam body more than or equal to 2 centimetres, described the second air hole to the distance on the base of sound beam body more than or equal to 0.5 centimetre.
More excellent scheme, the number of described the first air hole are at least 4, and the number of the second air hole is at least 3.Can be according to actual needs and the number of effect selection the first air hole, the second air hole.
The utility model beneficial effect against existing technologies is, because sound beam body has increased by the second air hole, and being shaped as of sound beam body cross-section top is trapezoidal, therefore the sound vibration of beam is stronger, sympathetic response significantly promotes, and this structure is particularly useful for being positioned at the sound beam corresponding with high tone code of high tone code below.
