Abstract

The utility model provides a four arc zither resonance box, includes double-arc soundboard, bottom plate and two end plates, the bottom plate is the double-arc equally, and the arc of indulging of bottom plate is the same with the arc of indulging of soundboard promptly, and the horizontal arc of bottom plate is opposite with the horizontal arc of soundboard. The double-arc soundboard and the outer edges of the two sides of the double-arc bottom board are directly bonded together. Adopt the utility model provides a zither of four arc resonance boxes preparation of zither can obtain good sympathetic response effect. The soundboard and the bottom board are directly bonded, the thickness of the kite body is not increased, and the appearance is attractive. The Chinese zither manufactured by the four-arc resonance box technology has balanced volume, uniform tone and transparent tone quality.

Description

Four-arc Chinese zither resonance box

Technical Field

The utility model belongs to the technical field of national musical instrument preparation, in particular to the preparation technique of zither.

Background

The existing Chinese zither resonance box is composed of a double-arc soundboard and a single-arc bottom board. The double-arc soundboard can focus and transmit the sound wave energy of the vibration of the strings of the Chinese zither to the bottom board of the resonance box to enable the Chinese zither to generate resonance. The base plate is a single arc, namely, the base plate is only provided with an upward convex radian in the longitudinal length direction and is flat in the transverse direction, the resonance box of the single arc base plate cannot fully focus and reflect sound waves, so that the reflection function of the base plate of the Chinese zither is weakened! Resulting in a small volume and a flat tone in the high tone area of the koto. The volume of the middle voice area is large, and the voice is empty. The bass zone is not sufficiently thick in tone.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the existing Chinese zither resonator bottom plate weakens the reflection of sound waves in each sound zone, and providing a four-arc Chinese zither resonator.

The technical scheme of the utility model

The utility model provides a four arc zither resonance box, includes double-arc soundboard, bottom plate and two end plates, the bottom plate is the double-arc equally, and the arc of indulging of bottom plate is the same with the arc of indulging of soundboard promptly, and the horizontal arc of bottom plate is opposite with the horizontal arc of soundboard.

The double-arc soundboard is directly bonded with the outer edges of the two sides of the double-arc bottom board.

The utility model has the advantages and beneficial effect:

adopt the utility model provides a zither of four arc resonance boxes preparation of zither can obtain good sympathetic response effect. The soundboard and the bottom board are directly bonded, the thickness of the kite body is not increased, and the appearance is attractive. The Chinese zither manufactured by the four-arc resonance box technology has balanced volume, uniform tone and transparent tone quality.

Detailed Description

Example 1:

the utility model provides a four arc zither resonance box, as shown in fig. 1 and fig. 2, including double arc soundboard 1, bottom plate 2 and two end plates 3, bottom plate 2 is the double arc equally, and the arc of indulging of bottom plate is the same with the arc of indulging of soundboard promptly, and the horizontal arc of bottom plate is opposite with the horizontal arc of soundboard.

The double-arc soundboard 1 and the outer edges of the two sides of the double-arc bottom board 2 are directly bonded together.

The four-arc koto is manufactured as follows:

1. the double-arc soundboard 1 is manufactured conventionally.

2. The double-arc base plate 2 is manufactured in the same manner. The longitudinal arcs of the double-arc bottom plate are the same as the longitudinal arcs of the soundboard, and the transverse arcs are opposite to the transverse arcs of the soundboard.

3. The end plate 3 is bonded with the inner sides of the soundboard and the bottom plate opposite to each other, the soundboard and the bottom plate are bonded together, and the four-arc resonance box is manufactured.

4. And other zither parts are manufactured conventionally.

Claims

1. A four-arc Guzheng resonator comprises a double-arc soundboard, a bottom board and two end boards, and is characterized in that the bottom board is also double-arc, namely the longitudinal arc of the bottom board is the same as that of the soundboard, and the transverse arc of the bottom board is opposite to that of the soundboard; the double-arc soundboard is directly bonded with the outer edges of the two sides of the double-arc bottom board.
