Abstract
The utility model relates to an urheen bridge provided with a resonant cavity, comprising a bottom substrate, an upper top cover, a lower base and a resonant cavity, wherein the bottom substrate is provided with string limiting slots and is hollowly cylindrical; the periphery of the upper top cover is provided with an outward convex covering edge; the periphery of the lower base is provided with an outward convex seat edge; and the resonant cavity is coaxially arranged between the upper top cover and the lower base, the peripheral cylindrical wall of the resonant cavity is provided with a plurality of minitype airflow holes and the middle part thereof is cylindrical. As the resonant cavity is arranged on the urheen bridge, in working, vibration sound wave of bows of a fiddlestick generated when the strings move and generate friction due to contact causes the airflow change in the resonant cavity by the urheen bridge of the resonant cavity, thus generating resonant wave superposed on the original vibration sound wave, enabling the music sound wave generated by a resonant tank string cylinder to comprise the composite of resonant sound wave, enable the lower voice to be thick and solid, and the high pitch to be louder and clearer, and realizing the positive technical effect of obviously improving the acoustic fidelity of the urheen.
Description
Technical field
This novel practical relates to a kind of musical instrument member, and particularly a kind of have an obvious urheen bridge that carries resonator cavity that improves the urheen acoustical quality.
Background technology
Urheen is a kind of traditional national musical instrument, mainly form by members such as qin tube, qin bar, scroll head, qin axle, very heavy, bridge, qin skin, string and bows, the qin tube is the resonating body of urheen, and inner the setting is hollow form, and outside surface is provided with an end of qin skin, qin bar, an end and the bridge of string; One end of qin bar is fixedly installed on the qin tube side, and that position, the nearly middle and upper part of the qin bar other end is provided with is very heavy, qin axle and scroll head; On the end face that one end of string is spacing by bridge supporting, be fixedly installed on the qin tube, the other end is held through very heavy button and is arranged on the qin axle after spacing.Wherein: described bridge be a kind of simple in structure, volume is less, the arch-shaped structural member that constitutes by bottom base and top stopper slot, it is the hinge that connects qin skin and string, its effect is on the qin skin of vibration sound wave through being transmitted to resonating body qin tube surface behind the bridge that produces when bow is spurred, contacts friction on string, realizes sounding.So though bridge only plays supporting and spacing string one end, in fact the version of bridge and material all have the certain influence effect to the tonequality variation of urheen.Set bridge all is the arch-shaped structural member of entity on traditional urheen at present commonly used, though simple in structure, easy to make, have only the function of direct conducted acoustic waves, do not have transition resonance function, thereby the improvement of urheen tonequality is not played obvious acting on substantially with.
Summary of the invention
The purpose of this utility model is to overcome that entity urheen bridge in the prior art is existing not to play the obviously weak point of effect substantially to the urheen tone quality improving, and a kind of urheen bridge that carries resonator cavity that can bring remarkable result to the urheen tone quality improving is provided.
The urheen bridge that carries resonator cavity of the present utility model is made of the bottom base of last band string stopper slot, be characterised in that described bottom base main body is hollow cylindrical, by the bottom base on the top top cover on paripheral zone outer gibbosity lid limit, paripheral zone outer gibbosity seat limit and coaxially be arranged between top top cover and the bottom base, barrel is provided with some miniature airflow holes on every side middle circle tubular resonator cavity constitutes, wherein; Described top top cover is provided with the string stopper slot; The surface configuration of described bottom base is installed with qin tube end surface shape and is conformed to.In addition, consider ease of processing, described bottom base is provided with fabrication hole and fills out inserts corresponding to the middle cylinder position.
Carry the urheen bridge of resonator cavity based on the utility model of above-mentioned design, owing to carry resonator cavity on the bridge, during work, bow hair on the bow is at the string superior displacement, the vibration sound wave that sends when coming in contact friction is causing variations in flow in the resonator cavity when carrying the bridge of resonator cavity, produce resonance wave, on the vibration sound wave that is added to original, the composition that includes resonant acoustic wave in the music sound wave that resonant tank qin tube is sent, make bass become abundant, high pitch is lamprophonia more, thereby realizes improving urheen tonequality significantly: can make the urheen pronunciation tone color of original pronunciation dullness pure and honest, toot sense is altogether more arranged; The musical sound that the urheen of original pronunciation oppressiveness is sent is louder, clear and melodious melodious, makes it to satisfy the requirement of playing vivacious and light-hearted tune; Can make the hoarse urheen sound of original pronunciation become soft more beautiful.Therefore, the utility model carries the rational in infrastructure and science of urheen bridge of resonator cavity, can make and be provided with the utility model to carry the urheen tonequality of urheen bridge of resonator cavity more graceful, interesting to listen to and melodious, satisfy actual request for utilization, thereby have very strong practicality and valuable market application foreground.
