Description

Split-cabin type guqin

Technical Field

The utility model belongs to the technical field of the guqin, concretely relates to structure is different from traditional subdivision formula guqin.

Background

The ancient lyre comprises panel and bottom plate two parts, and the panel is last, and wooden permeability is better for general fir or tung wood. The bottom plate is arranged below the base plate and is generally made of catalpa wood, so that the hardness is high and the support effect is mainly achieved. The finished product of the guqin is a long and narrow box-shaped structure and is provided with a cavity, the existing guqin cavity is the whole cavity, a head space is dug at the head of the guqin, and a small sound pool and a sound marsh are left in some guqin cavities, but the guqin occupies a small space in the length of the whole guqin. The absolute length of centre is a holistic elongated cavity, and the pronunciation vibration form of guqin ideal is for breathing the mode of vibration, and other mixed and disorderly modes of vibration can bring the noise promptly, but the appearance of mixed and disorderly mode of vibration can not be avoided to the whole cavity of guqin, does not have suitable and open technique at present to this problem and solves this problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a compartment formula guqin to the problem that exists among the prior art, this guqin is through installing multichannel subdivision founding additional in the guqin cavity, divide into several cabins to the whole cavity of guqin, has changed vertical rigidity distribution of guqin and mass distribution to adjust the natural frequency and the type of shaking of guqin, improve guqin tone quality.

The technical scheme of the utility model is that:

the utility model provides a subdivision formula guqin, includes panel, bottom plate and musical instrument frame, the musical instrument frame forms along the profile of guqin, the panel set up in the top frame portion of musical instrument frame, the bottom plate set up in the underframe portion of musical instrument frame, bottom plate, panel and musical instrument frame form the guqin cavity, the guqin cavity in be provided with the subdivision stud of cutting apart into a plurality of cabins with the guqin cavity, the height that highly is less than the musical instrument frame of subdivision stud, subdivision stud perpendicular to musical instrument frame, subdivision stud and panel between be provided with the gap.

Specifically, two end parts of the cabin-dividing stud are respectively connected with the piano frame.

Specifically, the cabin-dividing stud is in close contact with the bottom plate.

Specifically, a gap is arranged between the cabin-dividing stud and the bottom plate.

Specifically, the subdivision vertical ribs are at least two and are arranged in the cavity of the guqin to divide the guqin into three sound cabins.

The guqin is a national musical instrument with a long history. It has beautiful timbre and wide range of sound range, and various excellent tunes. However, because the volume is too small, only a loudspeaker can be used as a temporary remedy, and the problem cannot be solved fundamentally, and people have not broken through the problem for years. In addition, the tone of the guqin is adjusted, the cavity structure of the traditional guqin in the prior art is not changed, the tone and the volume of a high-sound part and a low-sound part are insufficient, the continuous improvement requirement of people appreciation level can not be met, and the higher and higher requirement on the guqin can not be met.

The utility model has the advantages that: this compartment formula guqin is through setting up a plurality of compartments founds muscle in the guqin cavity, divide into several cabins by original whole cavity to the guqin, thereby formed the compartment formula guqin structure of a complete difference with traditional guqin, changed vertical rigidity distribution and the mass distribution of guqin, change musical instrument body natural frequency and the type of shaking, thereby improve guqin tone quality, this compartment formula guqin is because the natural frequency and the type of shaking that can change the quantity adjustment guqin of compartment founding muscle according to the tuning needs, so the condition of specially adapted increase guqin cavity, thereby increase guqin volume.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1, the cavity of the compartmental guqin provided by this embodiment is schematically configured, the guqin includes a panel 1, a bottom plate 5 and a frame 4, the frame 4 is formed along the contour of the guqin, the panel 1 is disposed on the top frame portion of the frame 4, the bottom plate 5 is disposed on the bottom frame portion of the frame 4, the bottom plate 5, the panel 1 and the frame 4 form a guqin cavity, a compartmental stud 2 for dividing the guqin cavity into two compartments is disposed in the guqin cavity, the height of the compartmental stud 2 is smaller than that of the frame 4, the compartmental stud 2 is perpendicular to the frame 4, a gap is disposed between the compartmental stud 2 and the panel 1 and is not in contact with the panel so as to prevent sound from propagating in the cavity from being resisted, two end portions of the compartmental stud 2 are respectively connected with the frame 4, the compartmental stud 2 is in close contact with the bottom plate 5, and the compartmental stud is selected according to the mode vibration or mode vibration when the compartmental stud is not in contact with the bottom plate 5, the cabin-dividing studs 2 are not arranged above the sonar sound, and have no influence on the sound transmission of the sonar sound.

This embodiment changes the mass distribution and the rigidity distribution of guqin system through setting up two subdivision studs 2, adjusts several holistic natural frequency vibration types of guqin, and then improves the tone quality of guqin, and the width of subdivision stud 2 can be set for according to the size of guqin, and the subdivision stud of general guqin is 10-20mm, if bigger guqin, the width of its subdivision stud can be adjusted and increased so.

Example 2

This embodiment and embodiment 1 difference lie in the guqin cavity in be provided with six subdivision studs 2, as shown in fig. 2, fig. 3, fig. 4 are the longitudinal sectioning structure sketch map of this guqin cavity, six subdivision studs set up in the cavity inside and split into seven sound cabins with it, six subdivision studs 2 all can not set up in receiving the sound top, subdivision stud 2 and bottom plate 5 between be provided with the gap contactless, the both ends of subdivision stud 2 respectively with musical instrument frame 4 fixed connection can also integrated into one piece. Six subdivision studs 2 through setting up are split into seven sound cabins with the guqin cavity to formed the subdivision formula guqin structure of a complete difference and traditional guqin, changed musical instrument body natural frequency and the type of vibration, thereby improved guqin tone quality.

As shown in fig. 5 as the structural schematic diagram of traditional guqin cavity among the prior art, it has a holistic cavity and sends sound as the excitation of a resonant cavity response string, and the utility model discloses an establish a plurality of horizontal studs in the guqin cavity, divide into several cabins by original whole cavity to guqin to formed the cabin formula guqin structure of a complete difference and traditional guqin, changed musical instrument body natural frequency and the type of vibrating, thereby improve guqin tone quality, in addition the utility model provides a cabin formula guqin can change the natural frequency and the type of vibrating of quantity adjustment guqin of horizontal stud, so the condition of specially adapted increase guqin cavity, thereby increase guqin volume.
