Description

a lute

technical field

The invention relates to a stringed musical instrument, in particular to a pipa.

Background technique

Pipa is an ancient Chinese national musical instrument with a history of more than 2,000 years. The structure of the pipa mainly includes a neck, a panel and a backboard. The narrow and long part of the upper end of the pipa is called the neck, and there are six phonemes called phases, arranged in order from top to bottom. The lower part of the pipa body is scoop-shaped and consists of a panel and a back panel. The back panel is arc-shaped and connected around the pear-shaped panel to form a hollow resonance box. The upper part of the back panel and panel is connected to the neck. Generally, the resonance box extends upwards to the upper end of the sixth phase. The panels are generally inlaid and glued wooden panels, and twenty-five bamboo phoneme scales are glued to the panels from top to bottom. At the lower end of the panel is glued the bamboo replica hand used to tie the strings and transmit the resonance. The upper end of the string is wound on the peg, and the lower end is tied to the hand. A small hole is arranged on the panel below the compound hand to weigh the sound hole. Two crosspieces are glued close to the panel in the resonance box, and sound columns are supported between the two crosspieces and the piano body. The resonance box is equipped with an upper sound column and a lower sound column to divide the resonance box into three resonance areas.

In terms of production materials, most of the piano bodies are made of hard wood such as mahogany, rosewood, miscellaneous wood, etc. Panels, crosspieces and sound columns are all made of sycamore wood. When playing, the fingers buckle the strings between the phase and the frets, the strings vibrate, and after resonating through the resonance box, the sound is emitted from the sound hole. Since only 2/3 of the whole piano body is a speaker, the lower part of the phase to the headstock are all solid, the sound hole is too small, and is blocked by the double hand, therefore, the speaker of the traditional pipa is small, the channel is not smooth, and the sound quality is broken. Miscellaneous, the volume is also low. The sound column installed on the piano body is a dead sound column, which cannot be adjusted, so that the brightness of the sound sent by the pipa is not easy to achieve the desired effect. Simultaneously, the sound beam of existing pipa divides the resonant box into three resonant areas, and its resonant area is few, and sound wave is reflected in the resonant box, and the number of times of agitation is few, and the timbre of the sound that sends is not clear, mellow, and the rhyme is not long enough.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings in the prior art and provide a pipa with large volume, mellow timbre and ideal sound brightness. Furthermore, the utility model provides a pipa with more resonance areas, mellow timbre and long rhyme.

In order to achieve the above object, the utility model adopts the following technical solutions:

Preferably, one resonant hole is arranged on the left and right along the symmetrical center of the pipa.

Furthermore, the peg and the string are provided with a worm gear and a worm, and the worm gear and the worm are meshedly connected.

Preferably, the worm is fixedly connected to the peg, and the worm wheel is fixedly connected to the string.

Compared with the prior art, the utility model has the following advantages:

1. Increase the resonance box to increase the resonance volume;

2. The sound hole is added to ensure a smooth sound path;

3. The sound has a long and rounded rhyme, which can make the treble clear and rigid, the midrange soft and smooth, and the bass sound mellow;

4. The sound quality is mellow and the volume is large;

5. Easy and fast tuning.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, but is not limited thereto.

As shown in Figure 1, it is a structural schematic diagram of the pipa described in the utility model, including a neck 1, a panel 2 and a backboard 3, and the backboard 3 is arc-shaped and connected around the pear-shaped panel 2 to form a hollow resonance box 4. The upper part of the back plate 3 and the panel 2 is connected with the neck 1, the peg 5 is arranged above the neck 1, the complex hand 6 is provided at the lower part of the panel 2, the upper end of the string 13 is connected with the peg 5, and the lower end of the string 13 is connected with the complex hand The 6 phases are fixed, the neck 1 is provided with a plurality of parallel phases 14 corresponding to the positions of the strings 13, and several parallel frets 15 are provided on the panel 2 corresponding to the positions of the strings 13, and the panel at the bottom of the complex hand 6 2 is provided with a sound outlet 16, and the resonance box 4 is provided with an upper sound column 7 and a lower sound column 8 to divide the resonance box 4 into three resonance areas. The neck 1 is hollow to form a neck resonance box 9, The upper end of the neck 1 is provided with a neck sound outlet 10, and one end of the neck resonance box 9 communicates with the neck sound outlet 10, and the other end communicates with the resonance box 4; the upper fret 7 and the lower fret 8 are adjustable frets.

The resonance box 4 is also provided with a partition 11 parallel to the panel 2. The partition 11 runs through the upper sound column 7 and the lower sound column 8 to connect with the panel 2. The upper sound column 7 and the lower sound column 8 are located on the partition 11. A resonance hole 12 is provided between them, an upper resonance box is formed between the partition 11 and the panel 2, a lower resonance box is formed between the partition 11 and the back plate 3, and the lower resonance box communicates with the neck resonance box 9.

Resonance holes 12 are respectively provided with one along the symmetrical center of the pipa.

As shown in Figure 2, it is a schematic diagram of the appearance of the utility model. The sound hole 16 is respectively provided with one along the symmetrical center of the pipa panel.

When playing, some sound waves are reflected multiple times between the partitions, panels, and backboards, and resonate in multiple resonance boxes. At the same time, the resonance box in the neck part increases the volume of resonance, and there is also a sound outlet hole in the neck part, so that while retaining the original small sound outlet hole, the outlet is increased and the sound outlet path is guaranteed to be smooth. . Therefore, when the present invention is played, the rhyme is very long, the sound is mellow, the high pitch can be clear and full of rigidity, the mid-pitch is soft and embellished, the bass tone is full-bodied, and the sound quality is mellow and the volume is increased.
