[0026] The utility model provides a horn used for a full-frequency line array sound system, which comprises a cavity, wherein the cavity comprises a first cavity and a second cavity which are independent of each other and arranged side by side, the first cavity having a first inner cavity, the second cavity having a second inner cavity, the shapes of the first inner cavity and the second inner cavity are both wavy and the waveforms are opposite, and the planes where the waveforms of the first inner cavity and the second inner cavity are located are parallel to each other.

[0027] Since the cavity is provided with a first cavity and a second cavity which are independent of each other and arranged side by side, and the inner shapes of the two cavities are wavy and the waveforms are opposite, and the planes where the waveforms are located are also parallel to each other, the sound is smoother and more delicate, and the horn can enhance the smoothness and delicacy of the line array speaker.

[0028] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0029] See also Figure 1 and Figure 2 , a horn for full-frequency line array sound provided by the utility model, comprising a cavity 1, wherein the cavity 1 comprises a first cavity 11 and a second cavity 12 which are independent of each other and arranged side by side, wherein the first cavity 11 and the second cavity 12 are independently arranged so that the sound is diverted internally, so that the sound does not interfere with each other, and thus the sound is more realistic, and the high frequency is superimposed and coupled through the horn mouth, so that the high frequency energy is more concentrated. The first cavity 11 has a first inner cavity, and the second cavity 12 has a second inner cavity, and the shapes of the first inner cavity and the second inner cavity are both wavy and the waveforms are opposite, and the planes where the waveforms of the first inner cavity and the second inner cavity are located are parallel to each other, and the planes where the waveforms of the first inner cavity and the second inner cavity are located do not overlap, and in this embodiment, the plane where the waveform of the first inner cavity is located is at the upper end of the plane where the waveform of the second inner cavity is located, that is, the first cavity 11 is at the upper end of the second cavity 12. Since the cavity 1 is provided with a first cavity 11 and a second cavity 12 which are independent of each other and arranged side by side, and the inner shapes of the two cavities are wavy and the waveforms are opposite, and the planes where the waveforms are located are also parallel to each other, the sound is smoother and more delicate, and the horn can enhance the smoothness and delicacy of the line array speaker.

[0030] See also Figures 1 to 3As a further optimization scheme of Example 1, in this embodiment, the first cavity 11 includes a first left cavity 111 and a first right cavity 112 that can fit together, and the second cavity 12 includes a second left cavity 121 and a second right cavity 122 that can fit together, and the space enclosed by the first left cavity 111 and the first right cavity 112 forms a first inner cavity, and the space enclosed by the second left cavity 121 and the second right cavity 122 forms a second inner cavity. The first left cavity 111 and the second left cavity 121 are integrally formed to form a left half cavity 100, and the first right cavity 112 and the second right cavity 122 are integrally formed to form a right half cavity 200, and the left half cavity 100 and the right half cavity 200 are arranged axially symmetrically. Not only can it make the sound come out more smoothly, but also because the left half cavity 100 and the right half cavity 200 are axially symmetrically arranged, during the production process, the left half cavity 100 and the right half cavity 200 can share a mold, thereby reducing mold costs. The left half cavity 100 and the right half cavity 200 are also universal during maintenance and replacement, which can reduce inventory costs.

[0031] Furthermore, the peripheries of the left half cavity 100 and the right half cavity 200 are both provided with corresponding fitting parts 13, and the fitting parts 13 are provided with cavity fixing holes 14.

[0033] Furthermore, a positioning step 15 is provided on the outer surface of the cavity 1 near the sound outlet. The purpose of the positioning step 15 is to cooperate with the external horn to make the high-frequency directionality stronger. The function of the horn used in this full-range line array speaker is to make the high frequency more concentrated and the energy more sufficient, and the sound can be propagated farther through the cooperation of the external horn.

[0034] Furthermore, a base 2 is provided at the entrance of the cavity 1, and a sound inlet 21 is opened on the base 2. The first cavity 11 and the second cavity 12 share the sound inlet 21, so that the sound is superimposed and coupled at the horn mouth, so that the high-frequency energy is more concentrated.

[0035] Furthermore, four horn fixing holes 22 are provided on the base 2 for fixing the horn.
