Description

A kind of portable Zheng

One, technical field

The utility model relates to a kind of bullet and pulls out stringed musical instrument, specifically a kind of portable Zheng.

Two, background technology

Zheng is the traditional outstanding national musical instruments of China, and its tone color is graceful elegant, the mild and roundabout smoothness of harmonious sounds, and study gets up to go up quick-moving, easy crossing the threshold; Yet Zheng zither body is longer at present, carries inconvenience, is restricted at aspects such as study, amusements, influences popularizing of Zheng; Chinese patent 00254963.8 disclosed a kind of portable Zheng, its range is narrower, and a lot of melodies can not be played, and are a kind of child form Zheng, and compare with the plain edition Zheng at aspects such as volume and tonequality and not to be very desirable.

Three, summary of the invention

The purpose of this utility model is to provide a kind of range broadness, tonequality is pure, tone color is mellow and full and volume is grand portable Zheng.

The utility model adopts following proposal to realize above-mentioned purpose:

The utility model comprises zither head, zither tail, zither body, zither sign indicating number and zither string composition, described zither body is formed resonant jointly by the string shaft of panel, base plate, side plate, zither tail plate and zither head, be characterized in that described side plate is an arc, the zither tail plate medial surface is a cambered surface, be provided with a pair of liner in the zither body, between panel and the base plate, the side plate place of bottom, liner two ends laterally is provided with a pair of substrate sound beam vertical with liner.

The utility model design feature is: (1) is because of Zheng panel and the increase of side plate radian, strengthen the stress of panel, compare with common Zheng, under the identical situation of range scope, effectively shortened the length of zither body, and improved the acoustic resonance ability of Zheng, make Zheng sound grander, mellow and full, not only can compare favourably with common Zheng aspect tonequality and the tone color, and easy to carry, be fit to go out make the easier penetration and promotion of Zheng in aspects such as performance, study and amusement.(2) liner and the substrate sound beam in the zither body can increase zither body intensity on the one hand, improves the conduction of panel vibration sound wave, and the acoustic vibration power in each range of sound of balance especially makes the sound of bass area simpler and more honest, grand; The strong excessively effect of substrate sound beam may command base plate acoustic vibration on the other hand makes sound pure mellow and full, loud and clear and do not produce noise and empty sound.(3) because the zither tail plate medial surface is a cambered surface, be more conducive to the feedback and the sympathetic response of sound, increased the useful space of audio amplifier.
