[0008] Further, the two ends of the sound beam are attached to the sound box frame.
[0009] Further, the sound beam is bonded to the inner wall corresponding to the recess.
[0010] The utility model has the advantages that the utility model sets recesses in the sound board, so that the combination of the sound beam and the sound board forms a more stable structure, improves the stress and strength of the sound board, reduces the risk of breakage of the sound board, and at the same time, makes the vibration effect of the sound board better and improves the quality and clarity of the sound.

[0014] 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 one embodiment 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.
[0015] To make the objectives, technical solutions and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.
[0016] In the following description, references to "an embodiment," "an embodiment," "an example," "example," etc., indicate that the described embodiment or example may include a particular feature, structure, characteristic, property, element, or limitation, but not every embodiment or example necessarily includes that particular feature, structure, characteristic, property, element, or limitation. Furthermore, the repeated use of the phrase "an embodiment according to this application," while possibly referring to the same embodiment, does not necessarily refer to the same embodiment.
[0017] like Figs. 1-2 As shown, this utility model discloses a harp soundboard fixing structure, including two soundboards 1 symmetrically arranged on both sides of the speaker frame 2. The inner side of each soundboard 1 has a groove 4, and the two ends of the groove 4 correspond to the speaker frame 2. A sound beam 3 is installed in the groove 4, and the sound beam 3 is adapted to the groove 4.
[0018] In this embodiment, the two soundboards 1 and the soundbox frame 2 of the harp together form a resonating chamber. The size of the soundboards 1 matches the size of the soundbox frame 2. The soundbox frame 2 is a closed, irregular arc-shaped structure. The soundboards 1 cover both sides of the soundbox frame 2, and the two soundboards 1 are sealed to both sides of the soundbox frame 2 with sealant. The sound beam is a long strip structure, thicker in the middle and thinner at both ends, and is installed in the grooves 4 of the corresponding soundboards 1. The two ends of the sound beam 3 correspond to the soundbox frame 2.
[0019] The structure makes the sound beam 3 cooperate with the sound box frame 2 as an external supporting point of the sound board 1 when the sound board 1 is subjected to the string pressure, effectively shares and disperses the pressure borne by the sound board 1, improves the stress of the sound board 1, enables the sound board 1 to produce resonance more freely when vibrating, and thus improves the quality and clarity of the sound. Meanwhile, the close combination of the sound beam 3 and the sound board 1 helps the efficient conduction of the string vibration energy, so that the sound can be transmitted to the sound board 1 more quickly and resonance is produced. The efficient conduction mechanism helps to improve the sound quality and volume of the zither.
[0020] The utility model discloses a recess 4 is arranged on the sound board 1, and the combination of the sound beam 3 and the sound board 1 forms a more stable structure, improves the stress and intensity of the sound board 1, reduces the risk of the sound board 1 fracture, and simultaneously makes the vibration effect of the sound board 1 better, improves the quality and clarity of the sound.
[0021] In an embodiment, the cross section of the recess 4 is U-shaped. The U-shaped recess 4 provides a precise and stable mounting position for the sound beam 3. The sound beam 3 can be tightly embedded in the recess 4 and closely fit the two side walls of the recess 4, reducing the possibility of looseness and vibration.
[0022] That is, when the pressure generated by the string vibration is transmitted to the sound board 1, the design of the U-shaped recess 4 enables the sound beam 3 to more effectively disperse the pressure. Since the sound box frame 2 forms a support for the sound beam 3, the sound beam 3 can act as a solid bridge to disperse the pressure to a wider area of the sound board 1, thereby reducing the degree of single-point stress on the sound board 1.
[0023] In an embodiment, the two ends of the sound beam 3 are closely fitted with the sound box frame 2, so that the sound beam 3 is not only supported in the horizontal direction by the U-shaped recess 4 but also further stabilized in the vertical direction by the sound box frame 2. This greatly reduces the risk of deformation or fracture of the sound board 1 during vibration, and the close fit of the sound beam 3 with the sound box frame 2 enables smoother conduction of vibration energy to the inside of the sound box, thereby enhancing the resonance effect of the musical instrument. This improvement enables the zither to produce a more resonant, full and layered tone when played.
[0024] In an embodiment, the sound beam 3 is bonded with the inner wall of the corresponding recess 4. This connection method ensures a firm connection between the sound beam 3 and the sound board 1 while being simple to operate, low in cost and convenient for staff to assemble.
[0025] The design idea of the utility model is as follows:
[0026] A U-shaped recess 4 is provided on the sound board 1, which provides a precise and stable mounting position for the sound beam 3. The sound beam 3 can be tightly embedded in the recess 4 and closely fit the two side walls of the recess 4, and the sound beam 3 is closely fitted with the sound box frame 2.
[0027] Because the sound box frame 2 forms support to the sound beam 3, the sound beam 3 can be as a solid bridge, and the pressure is dispersed to the wider area of the sound board 1, thereby reducing the degree of the single point stress of the sound board 1. Effectively sharing and dispersing the pressure borne by the sound board 1, the risk of deformation or fracture of the sound board 1 in the vibration process is greatly reduced, so that the sound board 1 can be more freely resonated in the vibration, thereby improving the quality and clarity of the sound.
[0028] The utility model discloses a recess 4 is set up in the sound board 1, makes the combination of sound beam 3 and sound board 1 form a more stable structure, improves the stress and intensity of sound board 1, reduces the risk of sound board 1 fracture, simultaneously, makes the vibration effect of sound board 1 better, improves the quality and clarity of the sound.
[0029] The above description of the disclosed embodiments is to enable a person skilled in the art to implement or use the utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
