[0033] like Figures 1 to 3 As shown, a tweeter array speaker 10 includes a housing 100 and a speaker assembly 200. The housing 100 includes a rear housing 110 and a front cover 120. The front cover 120 is fastened to the rear housing 110 and has independent first mounting holes 121 and second mounting holes 122. The speaker assembly 200 includes a woofer 210, a tweeter cover 220, and at least three tweeters 230. The woofer 210 is disposed on the side of the front cover 120 near the rear housing 110. The woofer 210 is aligned with the first mounting hole 121. The tweeter cover 220 is disposed on the side of the front cover 120 away from the rear shell 110 and is aligned with the second mounting hole 122. The side of the tweeter cover 220 away from the rear shell 110 is recessed towards the rear shell 110 so that the tweeter cover 220 forms a sound guide groove 2211. Each tweeter 230 is disposed in a straight line at the lowest point of the sound guide groove 2211 and each tweeter 230 is equidistant from each other.

[0034] It should be noted that the front cover 120 is buckled and mounted on the rear shell 100, so that a relatively closed space is formed between the front cover 120 and the rear shell 110, and the first mounting hole 121 and the second mounting hole 122 are independent structures on the front cover 120. The bass speaker 210 is installed on the side of the front cover 120 close to the rear shell 110, so that the bass speaker 210 can emit sound through the first mounting hole 121. Further, the high-frequency cover plate 220 is installed on the front cover 120 by screws, and the high-frequency cover plate 220 is buckled in the second mounting hole 122, and the high-frequency cover plate 220 is recessed towards the rear shell 110 to form a sound guide groove 2211 on the high-frequency cover plate 220, so that the high-frequency cover plate 220 is funnel-shaped. Each high-frequency speaker 230 is installed at the lowest point of the sound guide groove 2211. In this way, more than three high-frequency speakers 230 are arranged in an array, and the sound propagation performance of the high-frequency speakers 230 is effectively enhanced under the action of the sound guide groove 2211, so as to reduce the interference between the bass speaker 210 and the high-frequency speaker 230, and make the high-frequency sound propagate farther. It should be noted that the bass speaker 210 and the high-frequency speaker 230 mentioned in the present application are both loudspeakers. Specifically, the bass speaker 210 is also called a bass unit or a subwoofer, which is specially used to reproduce lower frequency sounds, and usually covers a frequency range of 20Hz to 200Hz. The bass speaker 210 usually has a larger conical diaphragm to push more air, thereby producing a powerful low-frequency effect. The high-frequency speaker 230 is also called a high-frequency unit or a high-frequency speaker, which is responsible for reproducing higher frequency sounds, and its frequency range is 2kHz to 20kHz. Compared with the bass speaker 210, the high-frequency speaker 230 has a smaller size, and the diaphragm is usually made of lightweight materials such as carbon fiber and Kevlar to vibrate quickly and accurately reproduce high-frequency signals.

[0035] As shown in Figure 2 and Figure 4 shown, in an embodiment, the high-frequency cover plate 220 includes a sound guide plate 221 and a snap ring 222, the snap ring 222 is arranged on the edge of the sound guide plate 221, and the sound guide groove 2211 is located on the side of the sound guide plate 221 away from the snap ring 222. The front cover 120 also has a clamping groove 123 around the second mounting hole 122, and the snap ring 222 is adaptively accommodated in the clamping groove 123.

[0036] It should be noted that in order to tightly buckle the high-frequency cover plate 220 and the front cover 120, the high-frequency cover plate 220 is arranged to have a snap ring 222 structure. Specifically, when the high-frequency cover plate 220 is buckled on the front cover 120, the snap ring 222 is clamped in the clamping groove 123, so that the high-frequency cover plate 220 is tightly buckled with the front cover 120.

[0037] In an embodiment, the high-pitched cover plate 220 is made of light-conducting material, and a light-blocking layer is further arranged on the side of the high-pitched cover plate 220 away from the rear shell 110.

[0038] It should be noted that, in order to improve the appearance of the sound box, the high-pitched cover plate 220 is made of light-conducting material, for example, the high-pitched cover plate 220 can be made of transparent material such as polymethyl methacrylate, polycarbonate, polystyrene, polyethylene terephthalate, polyvinyl chloride, etc., so that the high-pitched cover plate 220 can conduct light well. Further, the light-blocking layer can be formed on the surface of the high-pitched cover plate 220 by an oil spraying process, for example, the light-blocking layer can be made of black ink, which only needs to block light. In this way, by reserving a hole position on the light-blocking layer, the high-pitched cover plate 220 can selectively emit light to improve the appearance of the sound box.

[0039] As shown in Figure 2 In an embodiment, the high-pitched cover plate 220 is further provided with a high-pitched circuit board 240 on the side close to the rear shell 110, and each high-pitched speaker 230 is arranged on the high-pitched circuit board 240.

[0040] It should be noted that each high-pitched speaker 230 is mounted on the high-pitched circuit board 240, so that the low-pitched speaker 210 and the high-pitched speaker 230 are driven by independent circuits, thereby avoiding signal interference between the two.

[0041] As shown in Figure 2 In an embodiment, a plurality of lamp beads 250 are further arranged on the high-pitched circuit board 240, and each lamp bead 250 is arranged towards the high-pitched cover plate 220. In this way, the light emitted by the lamp beads 250 can irradiate the high-pitched cover plate 220, so that the high-pitched cover plate 220 selectively emits light outward through the light-blocking layer.

[0042] As shown in Figure 1 and Figure 2 In an embodiment, the front cover 120 is further provided with a steel mesh 130. In this way, the steel mesh 130 can protect the low-pitched speaker 210 and the high-pitched speaker 230 on the one hand, and ensure that the sound passes through on the other hand.

[0043] As shown in Figure 2 In an embodiment, an auxiliary speaker 260 is further arranged on the inner side wall of each end of the rear shell 110. For example, the auxiliary speaker 260 is also a low-frequency unit, and by arranging a low-frequency unit on the front side, upper side and lower side of the sound box, the bass effect of the sound box can be improved.

[0044] As shown in Figure 1As shown, in an embodiment, the shell 110 further comprises a fixing frame 140, which is rotatably connected with two ends of the shell 110 respectively. In this way, the loudspeaker can be fixedly installed on the wall through the fixing frame 140, and the fixing frame 140 and the shell 110 are rotatably connected, so that the loudspeaker can be adjusted in left and right direction after being fixedly installed.

[0045] As shown in Figure 5 and Figure 6 As shown, in an embodiment, the fixing frame 140 is provided with a plurality of first protrusions 141, and the shell 110 is provided with a plurality of second protrusions 111. The fixing frame 140 is provided with a locking rod 150, which is screwed to the shell 110, so that each second protrusion 111 is engaged with each first protrusion 141.

[0046] It should be noted that, after the angle of the shell 110 relative to the fixing frame 140 is adjusted, in order to avoid loosening of the shell 110 relative to the fixing frame 140, the structure in which the first protrusions 141 and the second protrusions 111 are engaged is provided. Specifically, each first protrusion 141 is arranged in a circle on one end of the fixing frame 140, and each second protrusion 111 is also arranged in a circle on the shell 110. In this way, each first protrusion 141 is engaged with each second protrusion 111, and the locking rod 150 is screwed to the shell 110 after passing through the fixing frame 140. In this way, the angle between the shell 110 and the fixing frame 140 can be adjusted, and after adjustment, it can be reliably fixed to avoid loosening.

[0047] The above-described embodiments only express several embodiments of the present application, which are described in detail and specifically, but should not be understood as limiting the scope of the application. In the present application, the installation / fixed / setting is understood to include but not limited to locking and fixing by screws, welding, unless otherwise defined.
