Description

Technical Field

[0001] The invention relates to the technical field of horse-head fiddle, in particular to a three-cavity resonance horse-head fiddle. Background Art

[0002] The horse-head fiddle is named after the horse head carved on its head. It is called "chaoer" in Mongolian. It is a bowed string instrument with a long history in the Mongolian nationality. Since the day it was created, the horse-head fiddle has become a favorite instrument of the Mongolian nationality and has been widely spread. It has accompanied the Mongolian nationality through more than 1,300 years of history and has become an indispensable companion in the cultural life of the Mongolian nationality.

[0003] The sound box of the traditional horse-head fiddle is the vibration source cavity. The sound waves of different frequencies generated are transmitted outward through its box panels. The box cavity is the only sound-emitting cavity, which can easily lead to limited audio amplitude in some high-frequency bands. The overall audio amplitude is not balanced enough, making it more difficult to play and the sound expression is poor. Summary of the invention

[0004] The embodiment of the present invention provides a three-cavity resonance horse-head fiddle, aiming to solve the problems of the existing horse-head fiddle having an unbalanced audio amplitude, being laborious to play and having poor sound expression.

[0007] In this embodiment, the piano case has a box cavity, a headstock, a neck and a neck, which are arranged from top to bottom in an integrated manner. The bottom of the neckstock is fixed to the piano case. The headstock has a head cavity inside. The headstock has ear holes, eye holes and nostrils, which are connected to the head cavity and the outside world at the same time. The neck has a chest cavity at the lower position. The head cavity, chest cavity and box cavity are connected in sequence, and the strings are arranged between the piano case and the neckstock. Through the connection arrangement of the head cavity, chest cavity and box cavity, the audio is amplified by the resonance of the head cavity and chest cavity of different volumes and shapes, and then the sound is emitted from the opening of the piano case and the head cavity. After the three cavities resonate, the audio amplitude is balanced and bright, which can double the high-frequency volume, making the low-amplitude treble sensitive, easy to play and can emit a soft high-pitched melody, thereby enhancing the expressiveness of the piano sound.

[0008] In one embodiment of the present invention, the head cavity and the chest cavity are connected through a neck channel, the chest cavity and the box cavity are connected through a neck channel, and the front hole and the rear hole at the bottom of the neck channel are both connected to the box cavity.

[0022] Please refer to Figure 1 and Figure 2 A three-cavity resonance horse-head fiddle 10 comprises a musical instrument box 100, a rod assembly 300 and musical strings 500. The external structural diagram is also the same as that of a traditional horse-head fiddle.

[0023] See also Figure 2 The instrument box 100 of the three-cavity resonance horse-head fiddle 10 has a box cavity 110, and this specific feature is also the same as that of the traditional horse-head fiddle.

[0024] The body assembly 300 includes a headstock 310, a neck 330 and a neck 350, wherein the headstock 310, the neck 330 and the neck 350 are integrally arranged from top to bottom, the bottom of the neck 350 is fixed to the guitar case 100, the headstock 310 has a head cavity 370 inside, the headstock 310 has ear holes 311, eye holes 313 and nostrils 315, and the ear holes 311, eye holes 313 and nostrils 315 simultaneously connect the head cavity 370 and the outside world.

[0025] The lower part of the neck 330 has a chest cavity 390, and the head cavity 370, the chest cavity 390 and the box cavity 110 are connected in sequence. Figure 2 In a specific embodiment, the head cavity 370 and the chest cavity 390 are connected via the neck channel 700, the chest cavity 390 and the box cavity 110 are connected via the neck channel 900, and the front hole 351 and the rear hole 353 at the bottom of the neck channel 900 are both connected to the box cavity 110, which can make the connection between the head cavity 370, the chest cavity 390 and the box cavity 110 smoother.

[0026] In a specific implementation, the box cavity 110 is configured as a trapezoidal square cone, the chest cavity 390 is configured as an irregular fusiform column, and the head cavity 370 is configured as an irregular column, so that the volume of each cavity can be increased as much as possible.

[0027] At the same time, similar to the traditional horse-head fiddle, the strings 500 are arranged between the instrument case 100 and the neck 350 through two upper and lower bridges.

[0028] Example 1 S1. First, shape the outer contour of the 350mm raw wood of the guitar neck; S2, cutting downward from the middle of the two ears of the embryonic wood horse head to the fork at the bottom, so that the piano rod 350 is divided into two pieces of embryonic wood; S3, respectively carving out mirror-symmetrical grooves of the head cavity 370 and the chest cavity 390 on the two pieces of wood; S4. A 5mm diameter round hole is opened from the ear of each piece of wood blank to the head cavity 370, and the outer end is carved into a trumpet shape; a 4mm diameter round hole is opened from the nose to the head cavity 370, and the outer end is carved into a trumpet shape; a 3mm diameter round hole is opened from the eye to the head cavity 370, and the outer end is carved into a trumpet shape. The three cavities are formed with mirror-symmetrical through grooves using semicircular grooves with a diameter of 9mm; S5, bonding the two pieces of embryo wood according to the original cutting surface to form the secondary embryo wood of the horse head fiddle pole 350; S6, then enter the traditional horse-head fiddle production process, until the last step is completed, that is, the three-cavity resonance horse-head fiddle 10 is obtained.

[0029] Example 2 We use full-range high-fidelity recording equipment, standard echo-free, noise-avoiding recording studio, Waves audio software and PAZ-Frequency stereo display system.

[0030] For the traditional instrument and the three-chamber resonance horse-head fiddle 10 with the same appearance, the recording test of the equal-length playing of the bass open string and the equal-length playing of the treble open string were conducted to obtain multiple audio comparison test charts. For details, please refer to Figure 3-Figure 10 .

[0031] in, Figure 3-Figure 6 It is a cumulative display diagram of audio signals of each frequency, with the vertical axis being the cumulative amount of audio and the horizontal axis being the arrangement of different audio frequencies. It can be seen that the three-cavity resonance horse-head fiddle 10 has richer audio frequencies in the high-pitched region regardless of whether the treble strings or the bass strings are played.

[0032] at the same time, Figure 7-10 It is a vibration frequency and amplitude display diagram, with the vertical axis being the amplitude and the horizontal axis being the vibration frequency density. It can be seen that when the three-cavity resonance horse-head fiddle 10 is used for playing, the three cavities of the head cavity 370, the chest cavity 390 and the box cavity 110 can resonate, making the amplitude of the audio emitted more balanced and bright.

[0033] Through the three-cavity connection setting of the head cavity 370, the chest cavity 390 and the box cavity 110, the audio is amplified by the resonance of the head cavity 370 and the chest cavity 390 of different volumes and shapes, and then emitted outward from the openings of the piano box 100 and the head cavity 370. After the three-cavity resonance, the audio amplitude is balanced and the sound is bright. At the same time, the high-frequency volume can be doubled, so that no matter the treble strings or the bass strings, the audio in the high-pitched area is richer, the playing is easy and can produce soft high-pitched melody, thereby enhancing the expressiveness of the piano sound.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
