Description

Technical Field

[0001] The present invention relates to the field of harmonica accessories, and specifically to a resonance box device for changing the timbre of a harmonica. Background Art

[0002] A harmonica is a small wind instrument made of metal or plastic, with multiple reeds inside. The player makes the reeds vibrate by blowing or inhaling, and uses different hole positions and breathing techniques to play melodies. Its timbre is clear and bright, can imitate various instruments, and has rich expressiveness. The harmonica is easy to carry, suitable for playing music in styles such as blues, folk, and rock, and can be played solo or accompany songs. It is a popular and well-loved instrument.

[0003] In the field of research on the acoustic characteristics of musical instruments, when comparing the sound production principles and timbre performances of different musical instruments, the lack of resonance in the harmonica leads to a particularly significant problem of its thin timbre. String instruments such as violins and classical guitars are equipped with carefully designed resonance box structures. Take the violin as an example. Its body consists of a front panel, a back panel, and side panels to form a resonance cavity. When the strings vibrate, the wooden structure of the body amplifies and radiates the vibration energy of the strings through complex vibration modes, generating a rich overtone series, making the timbre full and rich in layers. The resonance box of a classical guitar also plays a key role. By optimizing the body shape, material, and internal support structure, the resonance effect of the sound is effectively enhanced, giving the music a warm and mellow quality.

[0004] On the contrary, the structure of the harmonica is relatively simple, mainly composed of reeds, a base plate, and a cover plate, lacking a resonance box similar to that of string instruments. During performance, the sound generated by the vibration of the reeds is directly radiated into the air through the cover plate, without a resonance structure to fully amplify and modify the sound. This structural feature makes the timbre of the harmonica relatively thin, and it seems inadequate when expressing grand and deep musical emotions. Therefore, the lack of resonance is an important limitation in the timbre performance of the harmonica and is also a key issue that needs to be focused on in future harmonica design and improvement. Summary of the Invention

[0005] To achieve the above object, the present invention provides the following technical solution: A resonance box device for changing the timbre of a harmonica, including an adapter ring, a resonance box is fixedly connected to the top of the adapter ring, a first partition is slidably connected inside the resonance box, and the adapter ring and the resonance box are integrally formed.

[0022] It should be noted that many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0026] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a resonance box device for changing the timbre of a harmonica, including an adapter ring 1, the top of the adapter ring 1 is fixedly connected with a resonance box 2, a first partition 3 is slidably connected inside the resonance box 2, and the adapter ring 1 and the resonance box 2 are integrally formed;

[0027] It has the following advantages: 1. Through the adapter ring, it can be conveniently installed on various harmonicas without changing the original structure and shape of the harmonica; 2. By changing the position of the partition in the resonance box, the internal space size of the resonance box is changed to find the best resonance point of the harmonica sound and enrich the artistic conception expressed during the harmonica performance; 3. By replacing two different types of partitions, the basic timbre of the resonance box can be changed, further enriching the performance ability of the harmonica;

[0028] This device can use the adapter ring 1 to be tightened outside the harmonica, and the internal volume of the resonance box 2 can be adjusted by sliding the first partition 3. When playing, the size of the internal space of the resonance box 2 can determine the timbre and volume of the resonance sound;

[0029] The benefits of adding a resonance box to a harmonica are as follows: 1. Enhance the volume and sound propagation effect, and amplify the sound intensity. Currently, due to the lack of a resonance box in ordinary harmonicas, the sound energy generated by the vibration of the reeds is limited, and the volume is relatively small. If a resonance box is added, when the reeds vibrate and produce sound, the resonance box can collect and amplify this vibration energy. Just like the body of a violin can convert the weak vibration of the strings into a louder sound, the resonance box of a harmonica can also make the harmonica emit a louder sound, enabling the performer to clearly transmit the sound in a larger space or a noisy environment; 2. Improve the sound propagation direction. For a harmonica without a resonance box, the sound scatters in all directions, and the propagation directivity is poor. After adding a resonance box, its shape and structure can be designed to make the sound propagate more specifically forward or in a specific direction. For example, designing a resonance box in a shape similar to a horn can project the sound concentratedly forward, improving the sound propagation efficiency and concentration, and allowing the listener to obtain a better auditory experience in a specific area; 3. Enrich and optimize the timbre, and increase the timbre layer. Different structures and materials of the resonance box will affect the resonance characteristics of the sound. When a resonance box is added to a harmonica, complex reflections and resonances will occur to the sound in the resonance box, generating rich overtones. These overtones are superimposed on the sound directly emitted by the reeds, making the timbre of the harmonica more rich, three-dimensional, and layered. Just like the resonance box of a classical guitar can make the sound produce warm and mellow overtones, the resonance box of a harmonica can also add a new dimension to its timbre; 4. Change the timbre characteristics. The design of the resonance box can change the original timbre characteristics of the harmonica. For example, using a wooden resonance box may make the timbre of the harmonica warmer and softer; while a metal resonance box may endow the harmonica with a brighter and crisper timbre. The performer can choose resonance boxes with different materials and structures according to different music styles and performance needs to achieve diverse timbre expressions; 5. Enhance the musical expressiveness and improve the sound sustainability. During the performance, when the vibration of the reeds weakens, the resonance box will continue to vibrate for a period of time due to its own inertia, so that the sound will not disappear immediately but gradually decay. This continuous sound effect makes the music more coherent and smooth, enhancing the musical expressiveness and appeal. When playing some long phrases or passages that require emotional continuity, the role of the resonance box is particularly obvious, enabling the listener to better feel the emotional connotation of the music; 6. Expand the adaptability to music styles. After adding a resonance box, the harmonica, due to the improvement in volume, timbre, and sound propagation, can adapt to more different styles of music performance. In classical music performances, its rich timbre and strong sound expressiveness can better interpret the emotions and artistic conceptions of the works; in pop music and jazz, the loud volume and good sound propagation effect can also make the harmonica more prominent in the band and better integrate with other instruments;

[0030] The adapter ring 1 includes an arc-shaped ring body 11 and a square ring body 12, and the square ring body 12 is fixedly connected inside the arc-shaped ring body 11;

[0031] The square ring body 12 is lower in height than the arc-shaped ring body 11. The arc-shaped ring body 11 is a boat-shaped structure that is wide at the top and narrow at the bottom. The bottom of the arc-shaped ring body 11 is open, and the entire adapter ring 1 is hollow in design.

[0032] The arc-shaped ring body 11 can be adapted to a harmonica with an arc shape, and the square ring body 12 can be adapted to a harmonica with a square shape. During installation, the harmonica of the corresponding shape can be inserted into the adapter ring 1 to fix the harmonica.

[0033] The arc-shaped ring body 11 adopts a unique design of being wide at the top and narrow at the bottom. This ingenious structure has significant advantages. The wide upper part can fully fit the corresponding part of the harmonica, and the narrow lower part forms a stable support and clamping force. The two work together to limit and clamp the harmonica well, effectively preventing it from loosening.

[0034] The resonance box 2 includes a box body 21 and a longitudinal slide groove 22. The longitudinal slide groove 22 penetrates and is formed in the box body 21.

[0035] The box body 21 is a semi-enclosed design with one side open, and the other side of the box body 21 is an arc-shaped structure, and the longitudinal slide groove 22 is opened on the other side of the box body 21;

[0036] The curved surface of the box body 21 is not randomly designed, but carefully built based on acoustic principles. Its smooth curved surface can effectively simulate an ideal sound collection environment. When the harmonica sounds, the scattered sound waves around can be collected by the resonance box 2 body in an all-round and accurate manner. This process is similar to the focusing effect in acoustics, which gathers the sound waves originally scattered in all directions into the box body.

[0037] After entering the resonance box 2, the sound is cleverly amplified by the special internal structure. The shape, material distribution, and air flow characteristics of the box work together to optimize the frequency response and amplitude of the sound, making the sound fuller, richer, and more layered.

[0038] The first partition 3 includes a partition handle 31, a partition body 32, a rotating rod 33 and an annular opening 34. The partition body 32 is fixedly connected to one end of the partition handle 31. The partition body 32 is rotatably connected to the top of the arc-shaped ring body 11 through the rotating rod 33. The annular opening 34 is opened on the surface of the partition body 32.

[0039] The partition handle 31 passes through the longitudinal slide groove 22 and slides in the longitudinal slide groove 22 to achieve the up and down swing adjustment of the first partition 3 in the resonance box 2;

[0040] In the resonance box 2, the cooperation between the partition handle 31 and the longitudinal chute 22 plays a crucial role. The partition handle 31 can slide flexibly within the longitudinal chute 22. This ingenious design enables the effective change of the space within the resonance box 2. When the partition handle 31 moves within the chute, the volume of the resonance box 2 will change dynamically. The change in the volume of the resonance box 2 will have a significant impact on the internal acoustic environment. Different volumes correspond to different air column lengths and resonance characteristics, thereby being able to change the overall timbre of the harmonica. The performer can flexibly adjust the position of the partition handle 31 according to different music styles and performance requirements to achieve diverse timbre adjustments, bringing more possibilities to harmonica performance;

[0041] During the actual use process, the performer can flexibly replace the first partition 3 with the second partition 4 according to the actual scenario requirements and the characteristics of the performance piece (see Figure 5 ). It should be noted that the internal structure of the second partition 4 is different from that of the first partition 3. It lacks the annular opening 34. This structural change causes the flow and resonance mode of air within the resonance box to change, and thus the timbre produced is different from that of the first partition 3. By freely replacing the partition, the performer can accurately adapt to different styles of music, adding more unique acoustic charm to the performance.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
