[0032] For example, in the above embodiment, if Figure 2 and Figure 3As shown, there are four speakers 2, and each speaker 2 is a 12-inch full-range speaker; the advantages of full-range speakers are: point sound source, accurate phase; the timbre of each frequency band tends to be consistent, which can easily bring better sound field, imaging, instrument separation and layering; because the mid-range stage has strong expressiveness, and most of the sounds made by people are dominated by mid-frequency, so full-range speakers are very suitable for listening to human voices, and the distortion rate of entering the ear is low, and the human voices performed are quite full and natural.

[0033] In some embodiments, Figure 1 As shown, the sound outlet side of the box 1 is arranged in an arc shape, and a plurality of loudspeakers 2 are sequentially distributed along the arc of the sound outlet side of the box 1. This arrangement further increases the coverage of the audio.

[0034] In other embodiments, the box body 1 may also be a linear box body 1, that is, a rectangular box body 1 or a columnar box body 1, etc.

[0035] In this embodiment, see Figure 2 , Figure 4 and Figure 5 As shown, the horn module includes a plurality of horn modules 3 corresponding to the loudspeakers 2, and the plurality of horn modules 3 are sequentially installed on the box body 1 in front of the sound outlet surface of the loudspeaker 2 along the height direction of the box body 1; specifically in this embodiment, the horn module includes four horn modules 3, which are installed one by one with four loudspeakers 2; each horn module 3 is provided with a plurality of horn units 300 sequentially distributed along its height direction and concave in the center, and a tweeter unit 4 is installed at the center of each horn unit 300, and the inner wall of the horn unit 300 is in the shape of a horn with a small center and a large outer edge. Specifically in this embodiment, each horn module 3 is provided with four horn units 300 sequentially distributed along its height direction and concave in the center.

[0036] In the above embodiment, the tweeter unit 4 on each horn module 3 forms a tweeter array, and the multiple speakers 2 and all the tweeter arrays together form the array sound, so that the coverage angle of the sound reinforcement and the sound propagation distance are greatly improved; in particular, the multiple horn units 300 distributed in sequence on the horn module 3 are arranged, and the inner wall of the horn unit 300 is in a horn shape with a small center and a large outer edge, and the outer edge of each horn unit 300 is arranged in a rectangular shape, which has a good treble diffusion effect, can effectively improve the audio reflection angle of the high-frequency part or the treble part, so that the treble coverage range is wide and the sound quality and sound effect are good.

[0037] It is not difficult to understand that if Figure 4 and Figure 5As shown, the inner wall of the horn unit 300 is arranged in an inwardly concave arc shape as a whole, and a center hole 303 is arranged in the center of the horn unit 300. A tweeter unit 4 is installed in the center hole 303. The tweeter unit 4 is also called a tweeter head, a tweeter, etc. The high-frequency audio frequency emitted by the tweeter unit 4 through high-frequency vibration can be reflected and diffused through the inner wall of the horn unit 300.

In this embodiment, the four horn units 300 are all distributed with sound-transmitting holes 302. The setting of the sound-transmitting holes 302 further increases the area of ​​the sound amplification surface or the reflection surface of the inner wall of the horn unit 300, which not only makes the treble energy diffuse more widely, but also allows the audio of the loudspeaker 2 to reverberate with the audio of the tweeter unit 4, so that the overall frequency response curve of the full-range loudspeaker can be adjusted, so that the overall frequency response curve of the sound is smooth, especially the harmony of the treble and the bass is more unified, so that the sound quality effect of the overall sound is good.

[0041] Further, in the above embodiment, the aperture size of the sound-transmitting hole 302 is 2 mm to 6 mm. Preferably, the aperture size of the sound-transmitting hole 302 is 4 mm.
