[0004] Currently, in order to prevent foreign matter from entering the inner cavity of the shell along the sound outlet channel, the sound outlet channel is generally provided with a dust screen. However, in actual use, the dust screen is prone to accumulate foreign matter, which can interfere with the transmission of sound, thereby causing poor sound production of the sound production module. CONTENT OF THE INVENTION

[0028] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0029] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0030] The sound generating module and the electronic device provided by the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments and application scenarios.

[0031] Please refer to Figures 1 to 6 As shown in the figure, the sound generating module provided in the embodiments of the present application includes a shell 100 and a dustproof net 200.

[0032] Specifically, the shell 100 is provided with an audio output channel 1111 and an audio output hole 121, the inner cavity of the shell 100, the audio output channel 1111 and the audio output hole 121 are sequentially communicated, and the hole wall of the audio output hole 121 is provided with a collecting groove 1211, and the groove opening of the collecting groove 1211 is communicated with the audio output hole 121.

[0033] The dustproof net 200 shields the audio output channel 1111, and the dustproof net 200 can block dust, iron filings, sand and other foreign matters from entering the audio output channel 1111, and the dustproof net 200 is arranged towards the audio output hole 121, that is, the foreign matters from the outside first reach the audio output hole 121, and then contact the dustproof net 200 after passing through the audio output hole 121.

[0034] In this embodiment, the wall of the sound outlet 121 is provided with a collection groove 1211, the opening of the collection groove 1211 is connected to the sound outlet 121, and the dustproof net 200 blocks the sound outlet channel 1111 and is positioned towards the sound outlet 121. With this arrangement, when foreign objects pass through the sound outlet 121, at least some of the foreign objects will enter the collection groove 1211 through the opening of the collection groove 1211 and accumulate in the collection groove 1211. In this way, the number of foreign objects reaching the dustproof net 200 is reduced, reducing the blockage of the sound outlet 121, thereby improving the sound output effect of the sound-generating module.

[0035] In addition, with fewer foreign objects reaching the dust filter 200, the number of foreign objects entering the sound outlet channel 1111 and the inner cavity of the housing 100 also decreases, thereby reducing the probability of blockage of the sound outlet channel 1111 and reducing the interference of foreign objects on the components in the inner cavity of the housing 100.

[0036] In another embodiment, reference Figure 2 As shown, the sound-generating module also includes a magnet 300, which is located in the collection tank 1211. With this configuration, the magnet 300 can attract ferromagnetic foreign objects, causing them to accumulate in the collection tank 1211. This reduces the number of foreign objects reaching the dust filter 200, resulting in better sound output from the sound-generating module.

[0037] In other alternative embodiments, the sound-generating module may also exclude the magnet 300, in which case foreign objects may accumulate in the collection tank 1211, for example, by gravity.

[0038] In another embodiment, reference Figure 6 As shown, the collection groove 1211 is arranged around the sound outlet 121. With this arrangement, the collection groove 1211 can collect foreign objects in all directions around the sound outlet 121, which also reduces the number of foreign objects reaching the dustproof screen 200, thereby improving the sound output effect of the sound module.

[0039] In other alternative embodiments, the collection groove 1211 may be formed only on a portion of the circumferential hole wall of the sound outlet 121.

[0040] In another embodiment, reference Figure 2 and Figure 3 As shown, the housing 100 includes a housing body 110, which has a sound outlet channel 1111. The housing 100 also includes a baffle 120, which is detachably connected to the housing body 110 and has a sound outlet hole 121. With this configuration, the collection groove 1211 is located on the baffle 120, and the baffle 120 can be disassembled and reassembled, thereby facilitating the cleaning of the collection groove 1211 and the replacement of the baffle 120.

[0041] Optionally, the sound-generating module is, for example, a loudspeaker, and correspondingly, refer to Figures 1 to 3 As shown, the sound-generating module may also include a vibration element 500 and an isolation mesh 600. The shell body 110 may include a first cover 111 and a second cover 112. The first cover 111 and the second cover 112 are ultrasonically welded together. The first cover 111 and the second cover 112 together form the inner cavity of the shell 100. A stop 120 is detachably connected to the first cover 111. The first cover 111 is provided with a limiting step. The vibration element 500 is bonded to the limiting step. The first cover 111 and the vibration element 500 together form the front sound cavity 700 of the sound-generating module. The sound outlet channel 1111 is provided in the first cover 111 and communicates with the front sound cavity 700. The second cover 112 and the vibrating element 500 form a rear sound cavity that surrounds the sound-generating module. The rear sound cavity is filled with sound-absorbing material. An isolation net 600 is disposed on the vibrating element 500 and is used to prevent the sound-absorbing material from interfering with the operation of the vibrating element 500. The isolation net 600 is, for example, adhered to the vibrating element 500.

[0042] In other alternative embodiments, the stop 120 and the shell body 110 may also be an integral structure, or the stop 120 may be connected to the shell body 110 by a non-removable means such as welding or gluing.

[0043] In another embodiment, reference Figures 1 to 3 As shown, the housing 100 includes a housing body 110, which has a sound outlet channel 1111. A dust filter 200 is detachably connected to the housing body 110. With this configuration, the dust filter 200 can be disassembled and installed, making it easy to clean and replace the dust filter 200.

[0044] In other alternative embodiments, the dustproof mesh 200 may also be connected to the shell body 110 by a non-removable method such as welding or gluing.

[0045] In one alternative embodiment, reference is made to... Figure 2 As shown, both the dust filter 200 and the baffle 120 are detachably connected to the housing body 110. For example, the dust filter 200 blocks one end of the sound outlet channel 1111 facing the sound outlet 121, and the baffle 120 has a clearance groove 122 on one end facing the housing body 110, with the dust filter 200 located in the clearance groove 122. With this layout, after removing the baffle 120, the dust filter 200 is exposed, making it easier to clean and replace.

[0046] In a further embodiment, the baffle 120 and the dustproof net 200 are detachably connected to the housing body 110, for example, via threaded connectors.

[0047] In a further embodiment, the blocking piece 120 is magnetically attracted to the shell body 110 so that the blocking piece 120 is detachably connected to the shell body 110; and / or, the dust screen 200 is magnetically attracted to the shell body 110 so that the dust screen 200 is detachably connected to the shell body 110. That is, either the blocking piece 120 or the dust screen 200 can be magnetically attracted to the shell body 110, or both the blocking piece 120 and the dust screen 200 can be magnetically attracted to the shell body 110.

[0049] In a further embodiment, as shown in Figures 1 to 4 The sound production module further includes a first magnetic attraction member 410 and a second magnetic attraction member 420, both of which are arranged around the sound outlet passage 1111. The first magnetic attraction member 410 is connected to the dust screen 200, and the second magnetic attraction member 420 is connected to the shell body 110. The first magnetic attraction member 410 is magnetically attracted to the second magnetic attraction member 420. In this way, the first magnetic attraction member 410 and the second magnetic attraction member 420 are magnetically attracted in multiple directions, thereby making the connection between the dust screen 200 and the shell body 110 more reliable.

[0050] Optionally, the first magnetic attraction member 410 is, for example, adhesively connected to the dust screen 200, and the second magnetic attraction member 420 is, for example, provided on the shell body 110 by means of injection molding or adhesion.

After being arranged in this way, the third magnetic attraction member 430 and the fourth magnetic attraction member 440 are magnetically attracted to each other in multiple different directions, so that the connection between the blocking member 120 and the shell body 110 is more reliable.

[0053] Alternatively, the third magnetic attraction member 430 is arranged on the blocking member 120 by, for example, injection molding or adhesion, and the fourth magnetic attraction member 440 is arranged on the shell body 110 by, for example, injection molding or adhesion. More specifically, the third magnetic attraction member 430 is adhesively connected to the blocking member 120 by, for example, gluing, and the fourth magnetic attraction member 440 is adhesively connected to the shell body 110 by, for example, gluing.

In this layout, in the second direction, the second magnetic attraction member 420 and the fourth magnetic attraction member 440 also have a spacing therebetween, thereby reducing the mutual interference between the second magnetic attraction member 420 and the fourth magnetic attraction member 440.

[0058] ​In other optional embodiments, the second magnetic attraction member 420 and the fourth magnetic attraction member 440 can also not have a spacing space in the second direction, that is, the two are in contact.
