However, due to the inherent structural and manufacturing limitations of small horn tweeters, the depth of the horn directly affects the high-frequency curve, making it difficult to perfectly reproduce high and ultra-high frequency audio, thus affecting clarity and detail reproduction.

Detailed Implementation

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] In the description of this utility model, the use of "first" and "second" is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein.

For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] In current technology, the main and auxiliary speakers of active speakers are generally connected via ordinary speaker wires. However, as speaker power increases and the distance between the two speakers grows, expensive high-purity copper speaker wires and gold-plated terminals must be used to reduce power loss. Furthermore, during prolonged use, the connectors will heat up and oxidize due to the continuous flow of high current, leading to poor contact later on. Additionally, since most power amplifier circuitry is integrated into the main speaker, the remaining space inside the main and auxiliary speakers is significantly different, resulting in inconsistent sound frequency characteristics between them.

[0023] Based on this, this utility model embodiment provides a high-frequency metal mesh that can improve the clarity and detail reproduction of high frequencies.

[0024] Firstly, referring to Figures 1 to 4 As shown, Figure 1 This is a top view of the high-frequency metal mesh provided in some embodiments of this application. Figure 2 This is a side view of a high-frequency metal mesh provided in some embodiments of this application. Figure 3 This is a side view of a tweeter metal mesh installed on a speaker cabinet, according to some embodiments of this application. Figure 4 This is a top view of a tweeter metal mesh installed on a speaker enclosure according to some embodiments of this application. The tweeter metal mesh includes an annular frame 100 and a mesh structure 200. The shape of the annular frame 100 matches the outer contour of the tweeter unit. The mesh structure 200 is fixed to the outside of the annular frame 100. The mesh structure 200 includes multiple radial iron bars 210. The first end of each iron bar 210 is connected to the annular frame 100. The extension lines of the first ends of each iron bar 210 intersect at the center of the annular frame 100. The iron bars 210 intersect to form multiple mesh holes. The multiple mesh holes are interconnected to form a honeycomb mesh structure 200.

[0025] The mesh includes a first polygonal hole 211, a second polygonal hole 212, and a third polygonal hole 213. The first polygonal hole 211 is connected to the annular frame 100, the second polygonal hole 212 is connected to the first polygonal hole 211, and the third polygonal hole 213 is connected to the second polygonal hole 212. A first high-frequency reflection superposition compensation layer is formed between the multiple first polygonal holes 211, a second high-frequency reflection superposition compensation layer is formed between the multiple second polygonal holes 212, and a third high-frequency reflection superposition compensation layer is formed between the multiple third polygonal holes 213.

[0026] It should be noted that by setting radial iron ribs 210 and multi-layer honeycomb mesh structure in the mesh structure 200, the first, second and third high-frequency reflection superposition compensation layers are formed, which can accurately guide, divide and superimpose the sound waves emitted by the tweeter unit. This design effectively overcomes the problems of high frequency attenuation, phase drift and loss of detail caused by the depth limitation of traditional small-sized tweeters. Through the multi-level reflection compensation mechanism, the high frequency, especially the extension of the ultra-high frequency band above 15kHz, is significantly extended, and the frequency response curve is smoothed, thereby greatly improving the clarity, resolution and airiness of the high-frequency reproduction. At the same time, the metal material of the ring frame 100 and the mesh structure 200 ensures the long-term stability of the acoustic characteristics and prevents the tweeter diaphragm from being damaged by contact.

[0027] In one possible embodiment, the first polygonal hole 211 is a closed triangular hole, the first polygonal hole 211 has an arc-shaped structure in the vertical direction, and the bottom edge of the first polygonal hole 211 is higher than the vertex of the triangular hole in the vertical direction.

[0028] In one possible embodiment, the second polygonal hole 212 is a closed quadrilateral hole. The second polygonal hole 212 has an arc-shaped structure in the vertical direction. The first included angle of the second polygonal hole 212 is higher than the second included angle of the second polygonal hole 212 in the vertical direction. The third included angle and the fourth included angle of the second polygonal hole 212 are on the same horizontal line. The first included angle and the second included angle are diagonal to each other. The third included angle and the fourth included angle are diagonal to each other.

[0029] It should be noted that, in the embodiments of this utility model, the first polygonal hole 211 adopts an arc-shaped triangular structure with the base side higher than the vertex, which cooperates with the arc-shaped quadrilateral structure of the second polygonal hole 212 with a specific spatial alignment. This unique, non-planar three-dimensional geometric arrangement can more accurately control the reflection path and phase of the sound wave, and realize multi-level, progressive sound energy guidance and superposition; thereby significantly enhancing the diffusion uniformity of high-frequency sound waves, effectively reducing the diffraction distortion common in horn, and making the final output high-frequency signal smoother and more delicate.

[0030] In one possible embodiment, the third polygonal hole 213 is an open quadrilateral hole. The third polygonal hole 213 has an arc-shaped structure in the vertical direction. The fifth included angle of the third polygonal hole 213 is higher than the opening of the third polygonal hole 213 in the vertical direction, and the fifth included angle is opposite to the opening. The sixth included angle and the seventh included angle of the second polygonal hole 212 are on the same horizontal line, and the sixth included angle and the seventh included angle are diagonal to each other.

[0031] It should be noted that, in the embodiments of this utility model, by designing the second polygonal hole 212 as a closed arc-shaped quadrilateral with a specific spatial alignment relationship, and precisely coupling it with the open third polygonal hole 213 with an asymmetrical arc structure, a gradual acoustic waveguide system from constraint to release is formed. This structure can finely control the sound waves generated by the tweeter unit. Its closed area effectively gathers sound energy and corrects the phase, while the open area guides the sound energy to diffuse smoothly and eliminates standing waves, thereby greatly suppressing the sound coloration phenomenon inherent in traditional iron mesh and realizing ultra-low distortion and extremely high transparency sound reproduction.

[0032] Furthermore, the annular frame 100 also includes a plurality of circular through holes 110, each circular through hole 110 surrounding the edge of the annular frame 100, and the circular through holes 110 are used as high-frequency resonance channels for the tweeter unit.

[0033] Furthermore, the annular frame 100 also includes a central through hole 120, which is located at the center of the annular frame 100 and is used to match the position of the tweeter unit.

[0034] It should be noted that in the embodiments of this utility model, by setting multiple circular through holes 110 around the edge of the annular frame 100 as high-frequency resonance channels, and opening a central through hole 120 at the center of the frame, a composite acoustic structure is formed. These through holes can effectively release unnecessary sound pressure and resonance generated inside the frame at extremely high frequencies, significantly reduce sound wave diffraction and energy accumulation. At the same time, the central through hole 120 ensures precise alignment with the diaphragm of the tweeter unit, avoids sound wave obstruction, and ultimately makes the high-frequency response smoother and more fluid, with excellent extension, eliminates the coloration of "metallic sound", and achieves a transparent and spatial high-frequency reproduction effect.

[0035] In one possible embodiment, the annular frame 100 is an arc-shaped structure, with its inner arc surface facing the tweeter unit; the mesh structure 200 is an arc-shaped structure, with its inner arc surface facing the tweeter unit.

[0036] Furthermore, the mesh structure 200 and the annular frame 100 are fixedly connected by welding.

[0037] Furthermore, in some embodiments, the high-frequency resonance band corresponding to the high-frequency metal mesh 10 is 15kHz.

[0038] It should be understood that in this utility model, "at least one (item)" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
