[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] like Figures 1 to 3 As shown, a waterproof speaker 10 includes a rear shell 100, a front shell 200, and a mesh cover 300. The front shell 200 is fastened to the rear shell 100. A mounting groove 210 is formed on the side of the front shell 200 away from the rear shell 100. A sound-producing element 400 is disposed in the mounting groove 210. A drainage groove 220 is also formed on the front shell 200, which communicates with the mounting groove 210. The mesh cover 300 is fastened to the front shell 200 to cover the mounting groove 210. The mesh cover 300 includes an outer frame 310, a plurality of first T-blocks 320, and a plurality of second T-blocks 330. Each first T-block 320 and each second T-block 330 are arranged alternately on the outer frame 310 so that a bent channel 340 is formed between any adjacent first T-block 320 and second T-block 330.

[0034] It should be noted that the front cover 200 is fastened to the rear cover 100, forming an inner cavity between the front cover 200 and the rear cover 100. The front cover 200 and the rear cover 100 can be secured together with screws. A mounting groove 210 is provided on the side of the front cover 200 away from the rear cover 100, and a sound-producing element 400 is installed within the mounting groove 210. Furthermore, a mesh cover 300 is fastened to the front cover 200, thus concealing the mounting groove 210. Specifically, the mesh cover 300 has several bent channels 340, each of which is formed using a first T-block 320 and a second T-block 330. Thus, the projections of each first T-block 320 and each second T-block 330 relative to the normal direction of the outer frame 310 are interconnected. Because the bend in the channel 340 prevents rainwater from reaching the speaker 400 in a straight line, and even if rainwater splashes into the bend in the channel 340, it will flow out through the drainage channel 220. Therefore, rainwater is prevented from accumulating inside the speaker 400, thus achieving the purpose of waterproofing.

[0035] like Figures 3 to 5 In one embodiment, the outer shell 200 is provided with a slot 230 around the outer periphery of the mounting groove 210. The slot 230 is connected to the drainage groove 220. A retaining strip 350 is provided on the side of the outer frame 310 near the outer shell 200. The retaining strip 350 is accommodated in the slot 230.

[0036] It should be noted that, in order to ensure that the mesh cover 300 fits tightly with the face shell 200 and to prevent rainwater from directly entering the gap between the mesh cover 300 and the face shell 200, a slot 230 is provided on the face shell 200 and a strip 350 is provided on the outer frame 310, so that the strip 350 is properly accommodated in the slot 230.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, in one embodiment, multiple drainage channels 220 are provided, each drainage channel 220 being distributed around the perimeter of the slot 230. For example, four drainage channels 220 are provided, each extending to one of the four sides of the faceplate 200. This ensures that rainwater splashed in from the bend channel 340 can flow out through one of the drainage channels 220, preventing it from accumulating inside the mesh cover 300 and damaging the sound-producing element 400.

[0038] like Figures 3 to 5 As shown, in one embodiment, a positioning groove 240 is also provided on the inner bottom wall of the card slot 230, and a positioning block 360 is also provided on the side of the outer frame 310 near the card slot 230. The positioning block 360 is adapted to be accommodated in the positioning groove 240.

[0039] It should be noted that, since the installation position of the mesh cover 300 relative to the face shell 200 is fixed, in order to facilitate the installation of the mesh cover 300 on the face shell 200, a foolproof structure is provided in which the positioning block 360 is inserted into the positioning groove 240, so that the mesh cover 300 can be installed quickly.

[0040] like Figure 5 As shown, in one embodiment, the mesh cover 300 further includes an inner ring 370, which is disposed on the side surface of the first T-block 320 and the second T-block 330 near the mounting groove 210, and the diameter of the inner ring 370 is smaller than the diameter of the outer frame 310. The inner ring 370 is used to abut against the sound-producing element 400.

[0041] It should be noted that, in order to further improve the sealing performance of the gap between the mesh cover 300 and the face shell 200, prevent rainwater from entering through the gap, and improve the structural strength of the mesh cover 300, an inner ring 370 is provided on the inner side of the outer frame 310. The inner ring 370 is provided on each of the first T-blocks 320 and each of the second T-blocks 330. In this way, the inner ring 370 and the retaining strip 350 form a tortuous structure to prevent rainwater from entering directly.

[0042] like Figure 2 and Figure 3 As shown, in one embodiment, the sound-producing element 400 includes a frame 410, a magnet 420, a diaphragm 430, a paper tube 440, a spider 450, and a voice coil 460. The frame 410 is disposed in the mounting groove 210, the magnet 420 is disposed at the bottom of the frame 410, the diaphragm 430 is disposed at the edge of the mounting groove 210 such that the inner ring 370 abuts against the edge of the diaphragm 430, one end of the paper tube 440 is connected to the diaphragm 430, and the other end of the paper tube 440 extends into the magnet 420. The spider 450 is connected to the frame 410 and the diaphragm 430 respectively, and the voice coil 460 is disposed on the outer wall of the end of the paper tube 440 near the magnet 420.

[0043] It should be noted that the sound-producing element 400 is used to produce sound. Specifically, the frame 410 is located within the mounting groove 210. In one embodiment, the frame 410 and the faceplate 200 are integrally molded plastic structures. Further, the magnet 420 is mounted on the bottom of the frame 410. The edge of the diaphragm 430 is connected to the mounting groove 210. One end of the paper tube 440 is connected to the diaphragm 430, and the other end of the paper tube 440 extends into the magnet 420. The spider 450 is connected to both the frame 410 and the paper tube 440, wherein the spider 450 and the paper tube 440 are coaxially mounted. Thus, under the action of the spider 450, the paper tube 440 is positioned at the center of the magnet 420. The voice coil 460 is a coil located within the magnet 420. Thus, by passing a changing audio electrical signal through the voice coil 460, the voice coil 460 generates a changing magnetic field, which, under the action of the magnet 420, causes the paper tube 440 to drive the diaphragm 430 to vibrate and produce sound.

[0044] like Figure 1 and Figure 2 As shown, in one embodiment, a socket 510 is provided on one side of the faceplate 200, and a conductive part 520 is provided inside the socket 510 for electrical connection with the voice coil 460. For example, the socket 510 and the faceplate 200 are also integrally formed. Furthermore, the conductive part 520 is a metal pin, and the conductive part 520 is installed inside the faceplate 200 by an integral forming process. In this way, while ensuring electrical connection between the conductive part 520 and the voice coil 460, the conductive part 520 is also waterproof.

[0045] like Figure 2 and Figure 4 As shown, in one embodiment, a plurality of fasteners 610 are provided on the side of the front shell 200 away from the rear shell 100, and each fastener 610 is used to fasten the mesh cover 300. It should be noted that a step is provided at the far end of the fastener 610, so that the mesh cover 300 can be fastened and fixed by the step, making the mesh cover 300 easy to install.

[0046] like Figure 1 As shown, in one embodiment, a fixing ear 710 is provided on the outer side wall of the rear housing 100. The fixing ear 710 has a through hole, allowing a screw to be passed through the through hole for secure mounting of the speaker. In one embodiment, multiple fixing ears 710 are provided, thereby improving the mounting stability of the speaker.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
