Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to an erhu effect sound generator. Background Art

[0002] The erhu, also known as the two-stringed fiddle, also named "Nanhu" and "Wengzi", is one of the main bowed string instruments (friction string instruments) in the musical instrument family.

[0003] Due to the relatively poor sound effect of traditional erhu, an electric erhu has emerged to improve the sound effect of the erhu. The electric erhu is an instrument that combines traditional erhu with modern high technology. Under the bridge, a small sound damping pad made of flannelette or felt must be stuffed between the strings and the membrane. It can solve the "wolf tone" of the erhu, eliminate the empty sound of the erhu, and make it concentrated and full.

[0004] Traditional electric erhus can only endow the musical sounds of the erhu with effects related to volume, and cannot achieve effects related to timbre such as reverberation, delay, and octave. Therefore, Chinese Patent No. CN101593513A discloses a sound pickup device, a controller, a sound effect device assembly, and an electric string instrument to solve the above problems.

[0005] In the above patent document, the erhu support on the erhu is fixedly installed on the sound effect device through bolts. This fixing method not only makes it difficult to disassemble and assemble the erhu, but also has a single specification and can only install erhu barrels of specific sizes.

[0006] In summary, how to realize the connection between erhu supports of different specifications and the erhu sound generator has become an urgent problem to be solved by researchers in this field. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is: how to realize the connection between erhu supports of different specifications and the erhu sound generator;

[0008] To solve the above technical problem, the technical solution adopted by the utility model is as follows:

[0009] The utility model is an erhu effect sound generator, including: a housing having a cavity for placing an erhu support; a support part is fixed at the bottom of the cavity; a first longitudinal pressing component or a second longitudinal pressing component or a first transverse positioning component is arranged on one inner wall of the cavity; a first longitudinal pressing component or a second longitudinal pressing component or a first transverse positioning component is arranged on the other inner wall of the cavity; the first longitudinal pressing component or the second longitudinal pressing component is adapted to drive a pressing plate to move longitudinally to press one side edge of the support against the upper surface of the housing and between the pressing plates; the first transverse positioning group is adapted to drive the pressing plate to move transversely to move the pressing plate to the upper surface of the support.

[0010] In this solution, the buttstock is placed inside the inner cavity of the housing. The supporting end inside the inner cavity is bent to form a displacement support end for the first longitudinal pressing assembly, the second longitudinal pressing assembly, or the first transverse positioning assembly;

[0011] The first longitudinal pressing assembly, the second longitudinal pressing assembly, or the first transverse positioning assembly can be combined and matched. For example, the first longitudinal pressing assembly and the second longitudinal pressing assembly can be used in combination, or the first longitudinal pressing assembly and the first transverse positioning assembly can be used in combination, or two first longitudinal pressing assemblies can be used in combination, and they are arranged on the two inner side walls of the inner cavity, with a total of 9 matching methods;

[0012] By using two first longitudinal pressing assemblies, two second longitudinal pressing assemblies, two first longitudinal pressing assemblies, or two second longitudinal pressing assemblies, the two sides of the buttstock can be pressed to prevent the buttstock from loosening;

[0013] However, when the buttstock is placed inside the inner cavity, the two pressure plates need to move to the upper limit state. The two pressure plates are driven by the first longitudinal pressing assembly or the two second longitudinal pressing assemblies to descend, and the corresponding pressure plates on both sides are pressed against the two sides of the buttstock;

[0014] By using the matching method of the first transverse positioning assembly and any longitudinal pressing assembly, it is convenient to place the buttstock inside the inner cavity; when the buttstock is in the pressed state, the distance between the two pressure plates is less than the length direction of the buttstock. The first transverse positioning assembly moves the pressure plates horizontally to increase the distance between the two pressure plates, which is convenient for placing the buttstock inside the inner cavity;

[0015] When the buttstock is placed inside the inner cavity, the first transverse positioning assembly drives the pressure plates to move horizontally, and then the first longitudinal pressing assembly or the two second longitudinal pressing assemblies drive the pressure plates to descend. At this time, the pressing force on one side of the support plate is weak, but at this time, the pressure plates on the other side do not have to be in the upper limit state;

[0016] In summary, by providing the first longitudinal pressing assembly, the second longitudinal pressing assembly, or the first transverse positioning assembly on one inner side wall of the cavity, the connection between buttstocks of different specifications and the housing is realized.

[0017] To illustrate the specific structure of the first longitudinal pressing assembly, the first longitudinal pressing assembly of the present invention includes: two symmetrically arranged first support feet, and the two first support feet are vertically arranged at the end of the support part; a first horizontal plate, a first horizontal plate V-shaped connecting piece is arranged at the end of the first support foot, a second horizontal plate is arranged at its top, and the horizontal pressure plate is arranged at its bottom; two first pressing pieces, which respectively pass through the first horizontal plate and are threadedly connected to the second horizontal plate;

[0018] In this solution, the first foot, the first horizontal plate, and the supporting part are formed by one-time bending. By rotating the first pressing member, the distance between the second horizontal plate and the first horizontal plate is adjusted, and then the distance between the pressing plate and the supporting part is adjusted to achieve the pressing of one side of the violin shoulder rest.

[0019] To illustrate the specific structure of the first lateral positioning assembly, the present utility model adopts that the first lateral positioning assembly includes: two second feet, and the two sides of the supporting part are respectively extended outwardly with the vertical second feet; a lateral moving member, on the top of which is provided with the pressing plate; two second pressing members, which respectively pass through the ends of the lateral moving member and are threadedly connected to the second feet.

[0020] In this solution, the second feet and the lateral moving member are oppositely arranged in the vertical direction. By rotating the second pressing member, the distance between the second feet and the lateral moving member is adjusted, and then the lateral displacement of the pressing plate is adjusted to place the pressing plate on the upper surface of the violin shoulder rest.

[0021] To achieve the pressing of violin shoulder rests with different thicknesses, the present utility model adopts that vertical waist holes are arranged at both ends of the lateral moving member; the second pressing member passes through the waist holes and is threadedly connected to the second feet.

[0022] In this solution, by adjusting the position of the second pressing member on the waist holes, the height of the pressing plate is further adjusted to adapt to violin shoulder rests with different thicknesses.

[0023] To illustrate the specific structure of the second longitudinal pressing group, the present utility model adopts two L-shaped feet, and the two sides of the supporting part are respectively extended outwardly with the L-shaped feet; a longitudinal moving member, on the inner side bottom of which is provided with the pressing plate; a third horizontal plate, which is arranged on both sides of the inner side of the longitudinal moving member; a third pressing member, which passes through the third horizontal plate and is threadedly connected to the horizontal part of the L-shaped foot.

[0024] In this solution, the horizontal part of the L-shaped connecting member and the third horizontal plate are oppositely arranged in the horizontal direction. By rotating the third pressing member, the distance between the third horizontal plate and the horizontal part is adjusted, and then the height of the pressing plate is adjusted to press the pressing plate on the supporting part.

[0025] The heads of the third pressing member, the second pressing member, and the first pressing member abut against the corresponding horizontal plates and all have threaded sections.

Detailed implementation mode

[0033] Now, the utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the utility model in a schematic way, so they only show the components related to the utility model.

[0034] As Figure 1 shown, the utility model is a sound generator with erhu effect, including: a housing 10, which has a cavity for placing the erhu violin rest 30; a support part 20 is fixed at the bottom of the cavity; a first longitudinal pressing assembly 1 or a second longitudinal pressing assembly 2 or a first lateral positioning assembly 3 is arranged on one inner wall of the cavity; a first longitudinal pressing assembly 1 or a second longitudinal pressing assembly 2 or a first lateral positioning assembly 3 is arranged on the other inner wall of the cavity; the first longitudinal pressing assembly 1 or the second longitudinal pressing assembly 2 is adapted to drive the pressing plate 4 to move longitudinally, pressing one side of the violin rest 40 against the upper surface of the housing 10 between the pressing plates 4; the first lateral positioning assembly 1 is adapted to drive the pressing plate 4 to move laterally, moving the pressing plate 4 to the upper surface of the violin rest 30;

[0035] In this solution, the violin rest is placed in the inner cavity of the housing, and the support end in the inner cavity is bent to form a displacement support end for the first longitudinal pressing assembly or the second longitudinal pressing assembly or the first lateral positioning assembly;

[0037] By using two first longitudinal pressing components, two second longitudinal pressing components, or two first longitudinal pressing components and two second longitudinal pressing components, the two sides of the violin rest can be pressed to prevent the violin rest from loosening;

[0038] However, when the violin rest is placed in the inner cavity, the two pressing plates need to move to the upper limit state, and the two pressing plates descend under the drive of the first longitudinal pressing component or two second longitudinal pressing components, and the corresponding pressing plates on both sides are pressed against the two sides of the violin rest;

[0039] By using the combination method of the first transverse positioning component and any longitudinal pressing component, it is convenient to place the violin rest in the inner cavity; when the violin rest is in the pressed state, the distance between the two pressing plates is less than the length direction of the violin rest, and the first transverse positioning component moves the pressing plates laterally to increase the distance between the two pressing plates, facilitating the placement of the violin rest in the inner cavity;

[0040] When the violin rest is placed in the inner cavity, the pressing plates are driven to move laterally by the first transverse positioning component, and then the pressing plates descend under the drive of the first longitudinal pressing component or two second longitudinal pressing components. At this time, the pressing force on one side of the support plate is weak, but at this time, the pressing plate on the other side does not need to be in the upper limit state;

[0041] In summary, by providing the first longitudinal pressing component, the second longitudinal pressing component, or the first transverse positioning component on one inner side wall of the cavity, the connection between violin rests of different specifications and the housing is realized.

[0043] In this solution, the first supporting foot, the first horizontal plate, and the supporting part are integrally formed by bending. By rotating the first pressing member, the distance between the second horizontal plate and the first horizontal plate is adjusted, and then the distance between the pressing plate and the supporting part is adjusted to realize the pressing of one side of the violin rest.
