[0014] The technical scheme in the embodiment of the utility model will be clearly and completely described in combination with the drawings in the embodiment of the utility model, and obviously, the described embodiment is only one embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0015] In order to make the purpose, technical scheme and advantage of the present application more clear, the present application will be further described in detail in combination with the drawings and specific embodiments.

[0016] In the following description, the reference to 'one embodiment', 'an embodiment', 'one example', 'an example' and the like indicates that the embodiment or example so described can include a particular feature, structure, characteristic, property, element or limitation, but not every embodiment or example necessarily includes the particular feature, structure, characteristic, property, element or limitation. Moreover, repeated use of the phrase 'in one embodiment' does not necessarily refer to the same embodiment, although it can.

[0017] As Figs. 1-2 Indicated, the utility model discloses a kind of high-strength sound board fixing structure of Qinxu, including two symmetrical sound board 1 being arranged in the both sides of sound box frame 2, the inside of two sound board 1 is opened with first recess 4, the both sides of sound box frame 2 are opened with second recess 5, second recess 5 is adapted to first recess 4, and it is formed with an installation groove, sound beam 3 is arranged in installation groove, and sound beam 3 is adapted to installation groove.

[0018] In the embodiment, two sound boards 1 and the sound box frame 2 of Qinxu are collectively surrounded into a resonance box, i.e. the size of sound board 1 is matched with the size of sound box frame 2, the sound box frame 2 is closed irregular arc structure, and the sound board 1 covers the both sides of sound box frame 2, and the both sides of sound box frame 2 are sealedly connected by two sound boards 1 through sealing glue. Sound beam is the long strip structure of thick middle and thin both ends, and is respectively installed in corresponding installation groove. That is, sound beam 3 can be firmly installed in installation groove, instead of simply embedding in the inside of sound board 1 or sound box frame 2.

[0019] When the soundboard is subjected to pressure from playing, the sound beam 3, securely mounted in the mounting groove and conforming to it, fully utilizes the supporting function of the speaker frame 2, providing additional support points and thus reducing the pressure on the soundboard 1. In other words, the soundboard is supported not only by the sound beam but also by the additional support of the speaker frame 2. This double-support structure makes the sound beam 3 more stable during vibration, helping to reduce deformation and loosening caused by vibration, further enhancing the stability of the soundboard 1. It avoids the risk of the soundboard 1 collapsing or breaking due to excessive pressure, thus significantly improving the load-bearing capacity of the soundboard 1 while increasing its durability and service life.

[0020] This invention features a first groove 4 on the soundboard 1 and a second groove 5 on the speaker frame 2, which together form a mounting groove for fixing the sound beam 3. Through the tight fit between the sound beam 3 and the mounting groove, the sound beam 3 can effectively distribute the pressure borne by the soundboard 1, thereby significantly improving the load-bearing capacity of the soundboard 1 and increasing its durability and service life.

[0021] In one embodiment, the first groove 4 has a U-shaped cross-section. The U-shaped groove design increases the contact area between the sound beam 3 and the soundboard 1, allowing the sound beam 3 to be more securely embedded during installation. Even under prolonged use and frequent playing, the soundboard 1 is less prone to damage due to uneven stress, and the installation of the sound beam 3 is also simpler. At the same time, this structural stability helps reduce noise and interference caused by vibration.

[0022] In one embodiment, the second groove 5 includes two mounting slots, which are respectively adapted to the two ends of the first groove 4, and the cross-section of the mounting slots is L-shaped. That is, in this embodiment, two symmetrical mounting slots are provided on both sides of the speaker frame 2, and the two mounting slots are respectively located at the left and right ends of the speaker frame 2, thereby fixing the two ends of the sound beam 3.

[0023] The L-shaped mounting groove design allows for easier and faster positioning and installation of the sound beam 3. This further increases the contact area and stability between the sound beam 3 and the speaker frame 2. The interplay between the L-shaped mounting groove and the U-shaped first groove 4 forms a more robust support structure, further enhancing the overall stability and durability of the soundboard 1 and reducing noise and interference caused by vibration.

[0024] In one embodiment, the two sides of the sound beam 3 are respectively bonded to the inner walls of the corresponding first groove 4 and second groove 5. This connection method ensures a firm connection between the sound beam 3 and the soundboard 1, while being simple to operate, low in cost, and easy for workers to assemble.

[0025] The design concept of this utility model is as follows:

[0026] By setting the first groove 4 with a U-shaped cross-section on the soundboard 1 and the second groove 5 composed of two symmetrical L-shaped slots on the sound box frame 2, the sound beam 3 is firmly installed between the soundboard 1 and the sound box frame 2, and the soundboard 1 is supported in multiple levels.

[0027] That is, when the soundboard 1 is subjected to the pressure generated by playing, since the sound beam 3 is firmly installed in the installation slot and the sound beam 3 is adapted to the installation slot, the structure can make full use of the supporting effect of the sound box frame 2, provide additional support points, so that the sound beam 3 can more effectively disperse and conduct the pressure generated by the string, thereby reducing the pressure borne by the soundboard 1. The risk of breaking the soundboard 1 due to excessive pressure is avoided, thereby significantly improving the durability and service life of the soundboard 1.

[0028] Since the lower the pitch of the string, the thicker the string, and thus the greater the pressure on the soundboard, and the higher the pitch of the string, the thinner the string, and thus the smaller the pressure on the soundboard. Therefore, the sound beam 3 can be installed in the form of double-slotted soundboard 1 and sound box frame 2 in the bass string area to disperse and absorb the pressure generated by string vibration, thereby ensuring the stress and strength of the soundboard 1 and preventing the soundboard 1 from breaking. In the treble string area, the sound beam 3 is installed in the form of a slotted soundboard 1, which can meet the support requirements without excessively increasing the weight and complexity of the soundboard 3, so that the vibration effect is better.

[0029] The utility model discloses a first groove 4 is set up on the soundboard 1, and the second groove 5 is set up on the sound box frame 2, and they jointly form an installation slot for fixing the sound beam 3. Through the close cooperation of the sound beam 3 and the installation slot, the sound beam 3 can effectively share the pressure borne by the soundboard 1, thereby significantly improving the durability and service life of the soundboard 1, and at the same time, it helps to reduce the noise and noise generated by vibration and improve the purity of sound quality.

[0030] The above description of the disclosed embodiments is that a person skilled in the art can 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.
