[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0027] See also Figure 1-Figure 6The utility model provides the following technical solutions: a speaker cover that is easy to replace the filter, including a speaker cover 1, a dust filter 2 and a protective cover 3. The speaker cover 1 includes: a card slot 104, and a plurality of card slots 104 are evenly spaced on the surface of the open end of the speaker cover 1, and the specific number of the card slots can be determined according to actual usage requirements. The dust filter 2 includes: a filter body 201 and a buckle 202. The buckle 202 is connected to one side of the filter body 201. The number of the buckles 202 needs to be adapted to the number of the card slots 104 to ensure that each buckle 202 can be inserted into the card slot 104. The buckle 202 is made of memory plastic material. The memory plastic material has a certain deformation and recovery ability after deformation, and can be conveniently inserted into the card slot 104 to realize the card assembly between the dust filter 2 and the speaker cover 1. The dust filter 2 is detachably connected to the open end of the speaker cover 1 through the buckle 202 and the card slot 104.

[0028] Preferably, the speaker cover 1 further comprises: a speaker cover body 101 , a paper cone 102 and a dust cover 103 , the paper cone 102 is arranged at the open end of the speaker cover body 101 , and the dust cover 103 is connected to the central opening of the paper cone 102 .

[0029] When used specifically, the function of the dust cover 103 is to prevent dust particles from falling into the voice coil and affecting the normal operation of the voice coil and the speaker unit. Using the dust cover 103 can extend the life of the speaker to a certain extent.

[0030] Preferably, the dust filter 2 further comprises an engaging groove 203 , which is disposed on a side of the filter body 201 away from the buckle 202 .

[0031] During specific use, a plurality of the embedding grooves 203 can be provided on the side of the filter body 201 according to actual needs, but the embedding grooves 203 must be arranged at equal intervals on the filter body 201 so that the magnetic attraction force can be uniform.

[0032] Preferably, the protective cover 3 comprises: a protective cover body 301 and a magnetic block 302 , the magnetic block 302 is connected to one side of the protective cover body 301 , the filter body 201 is a magnetic material, and the position and size of the engaging groove 203 are adapted to the position and size of the magnetic block 302 .

[0033] During specific use, the number of magnetic blocks 302 can be determined according to the number of actual interlocking grooves 203. After the magnetic block 302 is inserted into the interlocking groove 203, the protective cover 3 can be magnetically attracted to the surface of the dust filter 2 through the magnetic attraction of the magnetic block 302 and the magnetic material of the filter body 201, thereby protecting the dust filter 2 and effectively improving the service life of the dust filter 2.

[0034] Working principle: Figure 1As shown, if the dust filter 2 needs to be disassembled and replaced, the protective cover 3 can be first buckled off from the surface of the dust filter 2, and then the dust filter 2 can be buckled off from the surface of the speaker cover 1, so that the dust filter 2 can be disassembled, replaced or cleaned;

[0035] Secondly, after replacing the new dust filter 2, align the buckle 202 on the back of the dust filter 2 with the slot 104 opened at the open end of the speaker cover 1, and then press the dust filter 2 to make the buckle 202 deform and then snap into the slot 104, thereby fixing the dust filter 2. Finally, fit the protective cover 3 to the surface of the dust filter 2, and insert the magnetic block 302 into the engaging groove 203 to achieve the installation of the protective cover 3 on the surface of the dust filter 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
