Description

Technical Field

[0001] This utility model relates to the field of stringed instrument technology, and in particular to a bass stringed instrument. Background Technology

[0002] String instruments, as an important branch of the instrument family, play a central role in musical performance, providing melodic expression and harmonic support. Among them, low-pitched string instruments, capable of providing rich, low-frequency sound waves, are key instruments for constructing the low-frequency foundation of a musical soundstage and enhancing the layering of music. However, in the long course of development, traditional low-pitched string instruments have gradually revealed numerous technical shortcomings: 1. Existing electronic bass instruments such as electronic cellos and double basses, which rely solely on pickups and electronic circuits to adjust sound quality, cannot effectively reproduce the original timbre of traditional instruments, easily producing an "electronic sound," resulting in timbre distortion and poor auditory realism. 2. Existing electro-acoustic bass instruments lack the integration and utilization of the actual physical vibrations within the instrument body, and cannot form rich resonances from the superposition of multiple vibration sources. This results in fewer harmonic frequencies and disharmonious overtones, ultimately manifesting as thin sound quality and poor musicality. 3. Existing bass instruments used for ensembles lack the utilization of the inherent frequencies of real physical materials, making it impossible to achieve the superposition of multiple physical vibration timbres. This results in low harmony between their bass timbres and those of ethnic instruments, making it difficult to match the specific timbre requirements of ethnic music styles and affecting the overall sound effect of the ensemble.

[0003] To address some of the aforementioned issues, the existing patent with publication number CN216014789U discloses a mid-to-low-range stringed instrument, including a soundboard, an umbrella-shaped beam, a vibrating column, and inner and outer bridges. The soundboard has a hollow cavity inside, and the cavity is connected to the vibrating column through the umbrella-shaped beam to form a built-in bidirectional vibration structure. During operation, the outer bridge receives the vibration of the strings and transmits it to the vibrating column, which then conducts it to the side wall of the soundboard through the umbrella-shaped beam, thereby expanding the vibration area and increasing the vibration intensity.

[0004] This patent has made some progress in the timbre stability of mid-to-low-range stringed instruments by optimizing the physical vibration transmission path, but it still has obvious shortcomings in addressing the aforementioned core technical defects: its vibration structure relies only on the vibration transmission of a single material of the soundboard, umbrella beam and vibration column, without utilizing the inherent frequencies of different physical materials, and cannot form rich resonances of multi-source vibration superposition, and still suffers from problems such as lack of fullness of sound quality and insufficient harmonic harmony. Utility Model Content

[0005] This invention proposes a bass string instrument that solves the problem of thin sound quality caused by the lack of multi-source vibration resonance in the prior art.

[0006] The technical solution of this utility model is implemented as follows: A bass stringed instrument includes a stringed instrument shell, with an outer string and an outer bridge on the outside of the shell. The two ends of the outer string are connected to the stringed instrument shell, and the outer bridge supports the outer string. A resonant assembly is located inside the stringed instrument shell. The resonant assembly includes a resonant plate and an inner string. The resonant plate is connected to the inner wall of the stringed instrument shell and provides support to the outer bridge. The two ends of the inner string are connected to the resonant plate, and an inner bridge is located between the inner string and the resonant plate, supporting the inner string and keeping it taut. The resonant plate receives vibrations transmitted by the outer bridge, and the inner string can respond synchronously with the vibration of the resonant plate.

[0007] The stringed instrument shell is provided with a through hole, and the lower part of the outer bridge extends through the through hole into the interior of the stringed instrument shell and contacts the resonator plate.

[0008] The inner and outer strings are located on opposite sides of the resonant plate. This ensures that the inner and outer strings do not interfere with each other and can be superimposed for transmission.

[0009] The resonant plate is a long strip plate, with its top and bottom ends connected to the inner wall of the string instrument shell. The long strip plate is arranged in the same direction as the outer strings.

[0010] The inner and outer strings are arranged in the same direction.

[0011] The number of inner strings is multiple.

[0012] The resonant assembly also includes artificial python skin. A groove is provided on the resonant plate, and the edge of the artificial python skin connects to the edge of the groove, covering the groove. The artificial python skin provides support for the inner bridge. While providing elastic support for the inner bridge, the artificial python skin itself can vibrate with the vibration of the resonant plate.

[0013] The grooves are staggered with the outer bridge to prevent the vibration of the outer bridge from being directly transmitted to the artificial python skin, thus preventing a single vibration source from excessively interfering with the vibration characteristics of the artificial python skin.

[0014] A pickup is installed between the resonant plate and the outer bridge. The pickup collects the composite vibration signal of the resonant plate.

[0015] The lower part of the stringed instrument shell is equipped with a speaker, which is connected to a pickup.

[0016] The beneficial effects of this invention are as follows: by combining real physical methods with electronic technology, the vibration of the resonant plate built into the instrument body, the vibration of different frequencies of multiple strings, and the vibration of the artificial python skin are organically combined to generate a dense and rich frequency resonance. As industry professionals know, the more harmonic frequencies an instrument has, the more harmonious the overtones, and the fuller the sound will be, resulting in a beautiful and pleasant musical experience.

[0017] It adopts a composite technology approach of real physical vibration and electronic amplification, rather than relying solely on electronic circuits to adjust the sound quality. The pickup collects composite signals of multi-source physical vibrations, avoiding "electro-acoustic sound" and timbre distortion, restoring the original timbre of traditional bass string instruments, and improving the auditory realism compared to existing electro-acoustic bass string instruments.

[0018] The low-frequency sound waves of this instrument complement the mid-frequency sound waves of traditional Chinese instruments, enhancing the overall harmony of the ensemble sound. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, such as Figure 1 , Figure 2 , Figure 3As shown, a bass stringed instrument includes a stringed instrument shell 1, with an outer string 2 and an outer bridge 3 on the outside of the stringed instrument shell 1. The two ends of the outer string 2 are connected to the stringed instrument shell 1, and the outer bridge 3 supports the outer string 2. The instrument is characterized in that a resonant assembly 5 is provided inside the stringed instrument shell 1. The resonant assembly 5 includes a resonant plate 51 and an inner string 52. The resonant plate 51 is connected to the inner wall of the stringed instrument shell 1 and provides support for the outer bridge 3. The two ends of the inner string 52 are connected to the resonant plate 51, and an inner bridge 54 is provided between the inner string 52 and the resonant plate 51. The inner bridge 54 supports the inner string 52 and keeps the inner string 52 taut. In this embodiment, the string instrument shell 1 is a cello shell, and the playing method of the bass string instrument is the same as that of an ordinary cello. By combining real physical methods with electronic technology, the vibration of the resonant plate 51 built into the instrument body, the vibration of different frequencies of multiple inner strings 52, and the vibration of artificial python skin 53 are organically combined to generate a dense and rich frequency resonance, which makes the sound full of tone and thus makes the music beautiful and pleasant.

[0024] Furthermore, the string instrument housing 1 is provided with a through hole, and the lower part of the outer bridge 3 extends through the through hole into the interior of the string instrument housing 1 and contacts the resonator plate 51.

[0025] Furthermore, the inner string 52 and the outer string 2 are located on both sides of the resonant plate 51, respectively. This ensures that the inner and outer strings do not interfere with each other and can be superimposed for transmission.

[0026] Furthermore, the resonant plate 51 is a long strip plate, with its top and bottom ends connected to the inner wall of the string instrument shell 1. The long strip plate is arranged in the same direction as the outer strings 2. The inner strings 52 are arranged in the same direction as the outer strings 2.

[0027] Furthermore, the number of inner strings 52 is multiple. In this embodiment, the number of inner strings 52 is 3.

[0028] Example 2, based on Example 1, provides a bass stringed instrument where the resonant assembly 5 further includes an artificial python skin 53. A groove is provided on the resonant plate 51, and the edge of the artificial python skin 53 connects to the edge of the groove, covering the groove. The artificial python skin 53 provides support for the inner bridge 54. While providing elastic support for the inner bridge 54, the artificial python skin 53 can also vibrate with the vibration of the resonant plate 51.

[0029] Furthermore, the groove and the outer bridge 3 are staggered. This prevents the vibration of the outer bridge 3 from being directly transmitted to the artificial python skin 53, and prevents a single vibration source from excessively interfering with the vibration characteristics of the artificial python skin 53.

[0030] Furthermore, a pickup 6 is provided between the resonant plate 51 and the outer bridge 3. The pickup 6 collects the composite vibration signal of the resonant plate. A speaker 4 is provided at the lower part of the string instrument shell 1, and the speaker 4 is connected to the pickup 6. The speaker 4 receives the electrical signal transmitted by the pickup 6 and converts it into sound output.

[0031] Working principle: When the performer uses the bow to pull the strings, the vibration generated by the outer string 2 is transmitted to the resonant plate 51 through the outer bridge 3; after the resonant plate 51 is forced to vibrate, the vibration of the resonant plate 51 synchronously drives the artificial python skin 53 on it to produce elastic vibration, forming a multi-source composite vibration of "resonant plate 51, inner string 52, artificial python skin 53"; at this time, the pickup 6 collects the composite vibration signal, converts the vibration signal into an electrical signal and transmits it to the speaker 4, and after being amplified by the speaker 4, outputs a deep and full bass sound wave, completing the entire sound production process.

[0032] Application scenario: When used in conjunction with the erhu and guzheng to form a traditional Chinese musical instrument ensemble, the low-frequency sound waves of this instrument complement the mid-frequency sound waves of the traditional instruments, thus enhancing the overall harmony of the ensemble sound.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
