[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-6 As shown, this utility model proposes a dustproof and waterproof miniature loudspeaker, which includes a main mounting shell 1, in which a speaker body 2 is fixedly installed. At the bottom of the main mounting shell 1, a wire passage groove 10 is provided for the connecting wire 20 to pass through. To achieve sealing and fixing at the wire passage groove 10, a fixing shell 11 is installed at the bottom of the main mounting shell 1. The fixing shell 11 has a cover-like structure and completely covers the wire passage groove 10. Inside the fixing shell 11, a sealing plug 12 is provided. The connecting wire 20 of the speaker body 2 passes through the sealing plug 12. The sealing at the wire passage groove 10 is achieved by the elastic compression of the sealing plug 12, effectively preventing dust and moisture from entering the main mounting shell 1 from the wire passage groove 10 and affecting the normal operation of the speaker body 2.

[0025] At the top of the main housing 1, there is an annular screw edge 14. The outer wall of the screw edge 14 is machined with an external thread 15, which is used for threaded connection with other components. At the same time, a sealing ring 13 is installed at the top edge of the main housing 1. The sealing ring 13 is made of elastic rubber and has good sealing performance.

[0026] The dustproof and waterproof component 3 is composed of a top shell 36. The inner wall of the top shell 36 has a sealing groove 35 corresponding to the sealing ring 13. When the top shell 36 is screwed into the external thread 15 of the top screw edge 14 of the main shell 1 through the thread on the inner wall, the sealing ring 13 at the top of the main shell 1 is precisely embedded in the sealing groove 35 at the bottom of the top shell 36. Through the elastic deformation of the sealing ring 13, a sealing barrier is formed between the top shell 36 and the main shell 1 to prevent dust and moisture from entering from the connection between the two.

[0027] A dustproof net 30 is installed in the central area of ​​the top of the top shell 36, which is used to initially block larger dust particles. A waterproof and sound-permeable membrane 33 is also provided on the inner wall of the top shell 36. The waterproof and sound-permeable membrane 33 has a conical structure, and its center is fixed to the bottom of the dustproof net 30. The conical design helps to guide water to drain quickly and prevent water from accumulating inside the top shell 36. At the same time, an array of drainage holes 34 are provided on the outer wall of the top shell 36. These drainage holes 34 are located above the edge of the waterproof and sound-permeable membrane 33. When water enters the top shell 36, under the guidance of gravity and the conical waterproof and sound-permeable membrane 33, the water can be quickly discharged through the drainage holes 34.

[0028] The top of the top shell 36 is also provided with an annular twisted edge 31. The twisted edge 31 is arranged around the outside of the dustproof net 30, and the outer wall of the twisted edge 31 is machined with an external thread 32 for connecting with other components.

[0029] The bottom inner wall of the first dustproof shell 4 is machined with an internal thread that matches the external thread 32 of the second screw edge 31. The first dustproof shell 4 is screwed onto the second screw edge 31 of the top shell 36 by means of threaded connection. A second dustproof net 40 is installed on the top of the first dustproof shell 4. The second dustproof net 40 and the first dustproof net 30 cooperate to form a double dustproof structure. The mesh count of the first dustproof net 30 is greater than that of the second dustproof net 40, so that the first dustproof net 30 filters out larger dust particles first, and the second dustproof net 40 further blocks fine dust, effectively improving the dustproof effect.
