UrheenTechnical field
The utility model relates to a kind of urheen.
Background technology
Urheen is the traditional instrument of China, and there are two problems in traditional urheen, one, with big band, when band's cooperation that sound such as popular band ring was played, the Erhu playing person was difficult to clearly hear the urheen sound of own performance; Two, the volume of urheen itself is big inadequately, the needs in the time of can not satisfying the player and perform.
At above-mentioned situation, be necessary a kind of urheen newly developed, effectively improve above-mentioned present situation.
The utility model content
Technical problem to be solved in the utility model is, being difficult to hear at traditional Erhu playing person and spectators the problem of urheen pronunciation provides a kind of urheen with source of sound reflection function, makes the easier urheen pronunciation of hearing performance of Erhu playing person and spectators.
The utility model solves the problems of the technologies described above by following technical proposals:
A kind of urheen, comprise qin tube, qin bar, string and the vibration face of the qin tube front end that is laid in, qin bar lower end connects the qin tube, string one end connects the qin axle of qin bar upper end, the other end of string strides across the numeral on the qin tube front end vibration face, be connected with the lower limb of qin tube, relative with vibration face qin tube tail end is for reflecting the reflecting surface of urheen pronunciation.
Described reflecting surface is crooked arc-shaped curved surface.
Described reflecting surface is the tapered plane of bending.
Useful technique effect of the present utility model is:
Two-stringed piano drum has changed the structure of traditional two-stringed piano drum, the sound window direction of two-stringed piano drum tail end is changed into upwards (or to other directions) reflection urheen pronunciation, thereby improve the tonequality of urheen sound, increase the volume of urheen, the person that makes the Erhu playing can more clearly hear the performance of oneself, simultaneously, in the actual performance of music hall, the sound window that makes progress or reflect to other directions directly sends to the platform top reflecting plate of music hall stage or the reflecting body of other directions to sound, reflecting body by platform top reflecting plate or other directions reflexes to the auditorium, can allow spectators listen more clearly like this, loud.The reflection configuration of this two-stringed piano drum has also increased the overtone of urheen simultaneously, and the volume of urheen high position is increased, and sharpness strengthens.

Embodiment
As depicted in figs. 1 and 2, a kind of urheen, compriseqin tube 1, qin bar 2, string 3 and the vibration face 4 ofqin tube 1 front end that is laid in, qin bar 2 lower ends connectqin tube 1, string 3 one ends connect the qin axle 7 of qin bar 2 upper ends, the other end of string 3 strides across the numeral 5 on theqin tube 1 front end vibration face 4, is connected with the lower limb ofqin tube 1, and relative with vibration face 4qin tube 1 tail end is for reflecting the reflecting surface 6 that urheen pronounces.
Described reflecting surface 6 is crooked arc-shaped curved surface.
Described reflecting surface 6 is the tapered plane (not shown) of bending.
Protection domain of the present utility model is not limited to the foregoing description; reflecting surface 6 can be positioned at any position ofqin tube 1; the reflecting surface 6 that can reflect the urheen pronunciation that is provided with on theqin tube 1 all belongs to protection domain of the present utility model; under this design, reflecting surface 6 of the present utility model can have some variations.
