[0028] In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0029] The present utility model provides a coaxial horn, which includes a horn body, an embedded fixing part, and an extending fixing part. The vertical directivity angle of the horn body is 30 degrees - 60 degrees, the horizontal directivity angle of the horn body is 90 degrees - 180 degrees, and two first horn fixing holes are opened at both ends of the horn body near the throat. The embedded fixing part is arranged at the end of the throat of the horn body. There are two extending fixing parts, which are respectively arranged at both ends of the upper and lower unfolded surfaces of the horn body. Second horn fixing holes are opened at one ends of the two extending fixing parts, and the connection line of the center points of the two first horn fixing holes and the two second horn fixing holes is a straight line.
[0030] Since the vertical directivity angle of the horn body is 30 degrees - 60 degrees and the horizontal directivity angle of the horn body is 90 degrees - 180 degrees, the increased unfolding angle of the horn body enlarges the horn unfolding surface, thereby increasing the sound coverage angle of the coaxial horn, making the sound diffusion area wider and helping to block the columnar wave. This coaxial horn has a total of 4 fixing holes, with two fixing holes fixed on both sides of the horn throat and the other two fixing holes fixed on both sides of the horn unfolding surface, thus increasing the firmness of the horn. When the audio is working continuously, the horn can be kept from loosening or falling off, avoiding unnecessary losses and improving the competitiveness of the product. The connection line of the center points of the 4 fixing holes is a straight line, enabling the coaxial horn to be adjusted in both horizontal and vertical directions, and the direction of the horn can be adjusted according to the on-site requirements of customers to achieve the best on-site sound effect.
[0031] To enable those skilled in the art of this technology to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings. The present utility model will be described in detail below in conjunction with the drawings and embodiments. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0032] Please refer to Figures 1 to 4, a coaxial speaker horn provided by the utility model comprises a horn body 1, an embedded fixing part 2 and an extended fixing part 3, the vertical pointing angle of the horn body 1 is 30 degrees-60 degrees, that is, the upper unfolding pointing angle and the lower unfolding pointing angle are equal and both are 30 degrees-60 degrees, the horizontal pointing angle of the horn body 1 is 90 degrees-180 degrees, that is, the left unfolding pointing angle and the right unfolding pointing angle are equal and both are 90 degrees-180 degrees, and two first horn fixing holes 11 are opened at both ends of the horn body 1 near the throat; the embedded fixing part 2 is arranged at the throat end of the horn body 1; there are two extended fixing parts 3 and they are respectively arranged at both ends of the upper and lower unfolding surfaces of the horn body 1, one end of the two extended fixing parts 3 is opened with a second horn fixing hole 31, and the center point connection line of the two first horn fixing holes 11 and the two second horn fixing holes 31 is a straight line. Since the vertical pointing angle of the horn body 1 is 30 degrees to 60 degrees, and the horizontal pointing angle of the horn body 1 is 90 degrees to 180 degrees, the expansion angle of the horn body 1 increases, so that the expansion surface of the horn increases, thereby improving the sound coverage angle of the coaxial speaker horn, making the sound diffusion area wider and helping to block columnar waves. The coaxial speaker horn has a total of 4 fixing holes, two fixing holes are fixed on both sides of the horn throat, and the other two fixing holes are fixed on both sides of the horn expansion surface, thereby increasing the firmness of the horn. When the sound is working continuously, the horn can be prevented from loosening or falling off, avoiding unnecessary losses and improving the competitiveness of the product. The center point connection line of the 4 fixing holes is a straight line, so that the coaxial speaker horn can also be adjusted in both horizontal and vertical directions. The direction of the horn can be adjusted according to the customer's on-site needs to achieve the best on-site sound effect.
[0033] Furthermore, the vertical pointing angle is 60 degrees, and the horizontal pointing angle is 180 degrees, that is, the left expansion pointing angle and the right expansion pointing angle are equal and both are 180 degrees, and the upper expansion pointing angle and the lower expansion pointing angle are equal and both are 60 degrees. The increase in the expansion angle of the horn body 1 increases the expansion surface of the horn, thereby improving the sound coverage angle of the coaxial speaker horn, making the sound diffusion area wider and helping to block columnar waves.
[0034] Furthermore, the material of the horn body 1 is a composite material composed of polypropylene and glass fiber, which makes the horn stronger and less prone to breakage.
[0035] See also Figures 1 to 4 As a further optimization scheme of Example 1, in this embodiment, a reinforcing rib 4 is provided on the lower surface of the horn body 1 at the first horn fixing hole 11 to enhance the strength of the location so that the embedded fixing portion 2 can be more easily embedded.
[0036] Furthermore, the reinforcing rib 4 includes an annular rib 41 and a plurality of linear ribs 42 connecting the annular rib 41 and the horn body 1 , so as to enhance the strength of the reinforcing rib 4 .
[0037] Further, the horn body 1, the embedded fixing part 2, the extending fixing part 3 and the reinforcing rib 4 are made of the same material, which is a composite material composed of polypropylene and glass fiber in this embodiment. Moreover, the horn body 1, the embedded fixing part 2, the extending fixing part 3 and the reinforcing rib 4 are integrally formed.
[0038] Further, two first fixing columns 43 are provided at the reinforcing rib 4, and the first horn fixing hole 11 penetrates to the lower surfaces of the two first fixing columns 43 to improve the strength of the first horn fixing hole 11.
[0039] Further, a second fixing column 32 is provided on the lower surface of the extending fixing part 3, and the second fixing hole penetrates to the lower surface of the second fixing column 32 to improve the strength of the second horn fixing hole 31.
[0040] Further, a woofer and a tweeter are provided on the back of the unfolded surface of the horn body 1. The unfolded surface of the horn blocks in front of the woofer, which can increase the reflection of low-frequency sound waves, thereby increasing the sense of bass.
