[0023] In order to make the utility model's purpose, features, and advantages more obvious and easy to understand, the following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the embodiments described below are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0025] See also Figure 1-Figure 3 As shown, the utility model designs a speaker 100, which includes a sound output component and a dustproof net 5, the sound output component includes a cover plate 2, the cover plate 2 is provided with a sound output hole 3, the dustproof net 5 and the cover plate 2 are arranged relatively to each other, the speaker 100 also includes a connecting component, the first end of the connecting component is connected to the cover plate 2, and the second end of the connecting component is hot-melt connected to the dustproof net 5.

[0026] It should be noted that the dustproof net 5 of the present invention is connected to the cover plate 2. After dust or other debris enters the sound outlet 3, the dustproof net 5 can intercept dust or debris and prevent them from entering the interior of the speaker 100. The connection between the dustproof net 5 and the cover plate 2 is achieved by hot-melt connection of the connecting component. The connection performance between the dustproof net 5 and the cover plate 2 is greatly enhanced. Under long-term vibration, the dustproof net 5 can still be firmly connected to the cover plate 2, which solves the problem that the dustproof net 5 in the prior art is easily separated from the sound outlet component.

[0027] Specifically, an opening is provided at a position of the dustproof net 5 corresponding to the connecting component, and the area of ​​the opening is smaller than the cross-sectional area of ​​the second end of the connecting component.

[0028] Specifically, the connecting block 4 and the cover plate 2 are integrally formed.

[0029] Specifically, the cover plate 2 is fixedly connected to the connecting block 4 .

[0030] Specifically, the connection assembly includes a plurality of connection blocks 4 , and the plurality of connection blocks 4 are arranged at intervals on the cover plate 2 .

[0031] It should be noted that the connection block 4 of the utility model is initially set in a conical shape, and a plurality of connection blocks 4 are arranged on the cover plate 2 at intervals. The bottom surface of the connection block 4 (i.e., the first end of the connection block 4) is connected to the cover plate 2, and the dustproof net 5 is provided with an opening at the position corresponding to the connection block 4. When the dustproof net 5 is assembled, the opening of the dustproof net 5 corresponds to the connection block 4 one by one. The connection block 4 penetrates the dustproof net 5 until the cover plate 2 is attached to the dustproof net 5, and then the top end of the connection block 4 (i.e., the second end of the connection block 4) is melted by hot pressing welding or ultrasonic welding, so that the second end of the connection block 4 abuts against the dustproof net 5, and the area is larger than the area of ​​the opening, so that the dustproof net 5 can be firmly covered on the cover plate 2. Of course, it should be noted that in order to further enhance the connection performance of the cover plate 2 and the dustproof net 5, the connection block 4 and the cover plate 2 can be integrally formed or fixedly connected. At this time, the connection performance of the cover plate 2 and the first end of the connection block 4 is strong, which avoids the problem of the dustproof net 5 being separated from the cover plate 2 due to the separation of the first end of the connection block 4 from the cover plate 2.

[0032] Specifically, the distance between adjacent connection blocks 4 is between 4 mm and 10 mm.

[0033] Specifically, the cross-sectional area of ​​the second end of the connecting block 4 is between 1 mm 2 -3.5mm 2 .

[0034] Specifically, the opening mesh number of the dustproof net 5 is between 100 meshes and 200 meshes.

[0035] It should be noted that in order to explore the influence on the sound quality of the speaker 100, the utility model tests the spacing between adjacent connecting blocks 4, the cross-sectional area of ​​the second end of the connecting block 4 and the number of openings of the dustproof net 5. The test results show that when the spacing between adjacent connecting blocks 4 is between 4mm-10mm and the cross-sectional area of ​​the second end of the connecting block 4 is between 1mm 2 -3.5mm 2 When the number of openings of the dust-proof net 5 is between 100 meshes and 200 meshes, the speaker 100 produces sound, and the vibration amplitude of the dust-proof net 5 is in the preset range, the noise will not affect the sound effect, and the dust-proof net 5 will not easily fall off the sound-emitting component due to long-term vibration. Of course, it should be noted that the parameters of the preset range can be set by people themselves, and the present utility model does not limit this.

[0036] Preferably, the spacing between adjacent connection blocks 4 is 6 mm. Test results show that when the spacing between adjacent connection blocks 4 is 6 mm, the dust screen 5 has the smallest vibration amplitude and generates the least noise, and the connection performance between the dust screen 5 and the sound output component is strong.

[0037] Specifically, the cover plate 2 is a plastic part, and the connecting block 4 is a plastic part or a hot-melt adhesive part.

[0038] Specifically, the utility model tests the material of the connecting block 4 and finds that when the cover plate 2 is a plastic part and the connecting block 4 is one of a plastic part or a hot-melt adhesive part, the cover plate 2 has good connection performance to the connecting block 4. Both the plastic part and the hot-melt adhesive part have the performance of thermal expansion and contraction. When the top of the connecting block 4 is melted by hot pressing welding or ultrasonic welding and condenses, it will shrink and put pressure on the dustproof net 5, ensuring that the dustproof net 5 fits tightly to the cover plate 2, and the dustproof effect is good.

[0039] Specifically, the dustproof net 5 is one of nylon, copper or iron.

[0040] Specifically, the melting point of the dustproof net 5 is higher than the melting point of the connecting component, and the difference in melting points is greater than 120°C.

[0041] The melting point of the dustproof net 5 of the present invention is higher than the melting point of the connecting component, which ensures that the dustproof net 5 will not melt when the second end of the connecting block 4 is subjected to hot pressure welding or ultrasonic welding.

[0042] Specifically, the speaker 100 further comprises a speaker body 1, which is detachably connected to a cover plate 2. The cover plate 2 of the utility model is clamped to the speaker body 1, and when the dust screen 5 needs to be cleaned, the cover plate 2 can be removed for cleaning, which is very convenient.

[0043] Specifically, in order to prevent slipping, an anti-skid pad 6 is provided at the bottom of the speaker body 1 of the utility model.

[0045] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents.
