CN201910230U - Erhu - Google Patents

Abstract

The utility model discloses an Erhu, comprising a tube, a pole, strings and a vibrating membrane face, wherein the vibrating membrane face is laid at the front end of the tube; the lower end of the pole is connected with the tube; one end of each string is connected with a shaft at the upper end of the pole, and the other end of the string is connected with the lower edge of the tube over a counter on the vibrating membrane face at the front end of the tube; and the rear end of the tube opposite to the vibrating membrane face is a reflecting surface capable of reflecting the sound of the Erhu. The Erhu has the beneficial technical effects that the traditional tube structure is changed, and the direction of an acoustic window at the rear end of the tube of the Erhu is upward (or towards other directions) so as to reflect the sound of the Erhu, therefore, the tone quality of the sound of the Erhu is improved, and the sound volume of the Erhu is increased, so that an Erhu player can more clearly hear the sound of the Erhu played by the player; meanwhile, in the actual musical performance in a music hall, the acoustic window capable of reflecting upwards or towards other directions can directly send the sound to reflecting plates at the top of a stage of the music hall or to reflectors in other directions, and the sound is reflected to the audience through the reflecting plates at top of the stage or the reflectors in other directions, therefore, the audience can hear the sound more clearly and ringingly.

Description

Urheen

Technical 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, comprise qin tube 1, qin bar 2, string 3 and the vibration face 4 of qin tube 1 front end that is laid in, qin bar 2 lower ends connect qin 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 the qin tube 1 front end vibration face 4, is connected with the lower limb of qin tube 1, and relative with vibration face 4 qin 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 of qin tube 1; the reflecting surface 6 that can reflect the urheen pronunciation that is provided with on the qin 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.

Claims (3)

1. 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, it is characterized in that: relative with vibration face qin tube tail end is for reflecting the reflecting surface of urheen pronunciation.

2. urheen according to claim 1 is characterized in that: described reflecting surface is crooked arc-shaped curved surface.

3. urheen according to claim 1 is characterized in that: described reflecting surface is the tapered plane of bending.
