Description

Technical Field

[0001] The utility model specifically relates to a horn component connection structure. Background Art

[0002] The inventor has long been committed to the research of audio horn assemblies for sound amplification of audio equipment, such as the patent number CN201822246210.5, which is named a patent for a five-equally divided linear array segmented horn, wherein the horn assembly includes a horn and a waveguide connected to the bottom of the horn, and a channel for sound propagation is arranged inside the horn assembly. After the sound passes through the horn assembly, the sound wave energy is concentrated while having a wide radiation angle. In the horn assembly previously developed by the inventor, the horn and the waveguide are an integrated structure connected as one. In order to avoid resonance in the cavity, the horn is generally made of plastic or resin to form an overall solid structure. However, due to the large size of the parts, after being made by a one-time molding process such as injection molding, it is inevitable that problems such as local material collapse due to excessive shrinkage, material warping or deformation due to uneven temperature or cooling will occur, resulting in depressions on the surface of the horn or local structural deformation, which ultimately leads to poor horn sound amplification effect and a negative impact on the sound quality.

[0003] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content

[0023] The directions described in the utility model specification, such as "up", "down", "left", "right", "front", "back", etc., are based on the directions of the drawings and are intended to facilitate the description of the relationship between the various components. They do not indicate the unique or absolute positional relationship between the various components. They are only one of the implementation methods of the utility model and are not a limitation on its implementation method.

[0025] In more detail, Figure 2 As shown, the connecting structure 3 includes a threaded hole 31 arranged at the bottom of the horn member 1 and a mounting hole 32 arranged on the connecting seat 21 and corresponding to the threaded hole 31. A connecting bolt 33 for connecting the threaded hole 31 is passed through the mounting hole 32 from bottom to top. Of course, the connection relationship can also be achieved by a buckle and a clamping hole, that is, by providing a clamping hole on the horn member 1 and a corresponding buckle on the connecting seat 21.

[0026] In more detail, Figure 2 As shown, the bottom of the horn member 1 is provided with two rows of symmetrically arranged threaded holes 31, and the two rows of threaded holes 31 are respectively located at the front and rear sides of the lower end of the sound reinforcement channel 10, and the connecting seat 21 is correspondingly provided with two rows of mounting holes 32, and the two rows of mounting holes 32 are respectively located at the front and rear sides of the upper end of the sound guide channel 20.

[0027] As a preferred solution, Figure 3 and Figure 5 As shown, the waveguide 2 is provided with a central sound guide block 22 in the sound guide channel 20. The central sound guide block 22 is located in the middle position of the sound guide channel 20 in the left-right direction. The central sound guide block 22 extends from the upper end of the sound guide channel 20 to the lower end of the sound guide channel 20. The central sound guide block 22 is spindle-shaped with a large middle part and small upper and lower ends. In this way, the sound waves entering from the lower end of the sound guide channel 20 can be relatively concentrated and diffused toward the left and right sides, thereby improving the sound amplification effect.

[0028] As a better solution, Figure 3 and Figure 5As shown, the waveguide 2 is provided with two offset sound guide blocks 23 in the sound guide channel 20, and the two offset sound guide blocks 23 are respectively located on both sides of the central sound guide block 22, and the offset sound guide block 23 is a spindle shape with a large middle part and small upper and lower ends, and the offset sound guide block 23 is gradually bent from top to bottom toward the central sound guide block 22, so that the sound waves diffused after being guided by the central sound guide block 22 are diffused again toward the two sides of the offset sound guide block 23, thereby improving the sound amplification effect. In addition, the offset sound guide block 23 is set to a curved shape to reduce the loss of sound wave energy and improve the performance of sound propagation.

[0029] As a better solution, Figure 3 and Figure 5 As shown, the waveguide member 2 is provided with a first sound guide plate 24 and a second sound guide plate 25 in the sound guide channel 20, the first sound guide plate 24 is located between the central sound guide block 22 and the offset sound guide block 23, the first sound guide plate 24 is gradually bent from top to bottom in a direction away from the central sound guide block 22, the second sound guide plate 25 is arranged on a side of the offset sound guide block 23 away from the central sound guide block 22, the second sound guide plate 25 is gradually bent from top to bottom in a direction close to the offset sound guide block 23, the first sound guide plate 24 and the second sound guide plate 25 play a role in guiding sound waves.

[0030] As a preference, Figure 2 and Figure 3 As shown, the horn 1 is provided with a plurality of sound insulation boards 11 in the sound amplification channel 10. When the horn 1 is connected to the connecting seat 21, the lower end of the sound insulation board 11 is connected to the upper end of the central sound guide block 22, the upper end of the offset sound guide block 23, the upper end of the first sound guide board 24 or the upper end of the second sound guide board 25. Preferably, the lower end of the sound insulation board 11 and the upper end of the central sound guide block 22, the upper end of the offset sound guide block 23, the upper end of the first sound guide board 24 or the upper end of the second sound guide board 25 are correspondingly provided with sound insulation boards 11. Of course, it is sufficient to provide the sound insulation board 11 on the upper end of some structures. The sound insulation board 11 serves to block sound waves, and sound waves in channels of different directions interfere with each other, thereby improving the stability of the emitted sound waves and improving the sound quality.

[0031] In detail, Figure 5As shown, the waveguide component 2 is composed of two symmetrically arranged waveguide shells 200, and the inner side wall of the waveguide shell 200 is provided with a raised first boss 202, a second boss 203 and a first connecting plate 204 and a second connecting plate 205. When the two waveguide shells 200 are combined, the first bosses 202 of the two waveguide shells 200 are connected to form the central sound guide block 22, the second bosses 203 of the two waveguide shells 200 are connected to form the offset sound guide block 23, the first connecting plates 204 of the two waveguide shells 200 are connected to form the first sound guide plate 24, and the second connecting plates 205 of the two waveguide shells 200 are connected to form the second sound guide plate 25. The two waveguide shells 200 can be connected and combined by bonding, hot melting or other connecting methods to form the waveguide component 2.

[0032] As a preference, since the connecting bolts 33 are generally made of metal, when sound waves propagate through them, metal parts have good sound conduction performance, that is, sound waves propagate faster in metal and are more likely to interfere with sound waves in the channel. Therefore, Figure 2 As shown, a mounting boss 12 is provided at the bottom of the horn member 1, and the threaded hole 31 is arranged on the mounting boss 12. A sound insulation cavity 13 is also provided on the mounting boss 12. The sound insulation cavity 13 is located between the threaded hole 31 and the lower end of the sound guiding channel 20, and the sound insulation cavity 13 blocks the sound waves from being directly propagated to the connecting bolt 33.
