[0043] In related technologies, such as Figure 1 As shown, the installation of the speaker net 300 is first positioned by a jig, and then one side of the long side of the speaker net 300 is inserted into the frame 100 profile, and then the tongue piece of the other long side of the speaker net 300 is squeezed into the notch of the frame 300, and then the tongue piece is bent from the back of the frame 100, so as to achieve the fixation of the speaker net 300. Since in the frame of this structure, the fixation of the speaker net 300 and the frame is mainly achieved by the positioning groove on the profile and the bending limit of the speaker net. In this case, the speaker net and the positioning groove need to be limited by a tight fit. When the long side of the speaker net is inserted into the limit groove in the frame 100, it is too long and deformed, resulting in difficulty in insertion. In addition, the fixation of the speaker net requires manual bending of the tongue piece, which is time-consuming and labor-intensive.

In this way, the width of the first through slot and the second through slot for the two ends of the speaker net to pass through can be set to be slightly wider than the thickness of the speaker net, so as to facilitate the passage of the speaker net. In this way, even if the speaker net is deformed due to its excessive length, it can be inserted into the receiving groove from the first through slot and the second through slot, and there is no need to manually bend the tongue of the speaker net during installation, thereby improving the installation efficiency.

[0045] See also Figures 2 to 7 An embodiment of the utility model provides a speaker mesh fixing device for fixing a speaker mesh 300, the speaker mesh 300 fixing device comprises a frame 100 and a fixing member 200, the frame 100 is configured with a accommodating cavity 110, the frame 100 comprises a first side wall 120, the first side wall 120 is provided with a first through groove 121 and a second through groove 122 which penetrate the first side wall 120 along the thickness direction of the first side wall 120, the first through groove 121 and the second through groove 122 are both connected to the accommodating cavity 110, the first through groove 121 and the second through groove 122 are used for allowing two ends of the speaker mesh 300 to pass through and extend into the accommodating cavity 110; one end of the fixing member 200 can extend into the accommodating cavity 110 and be connected to the speaker mesh 300, and the other end is detachably connected to the frame 100; wherein both ends of the speaker mesh 300 extending into the accommodating cavity are fixed to the frame 100 by the fixing member 200.

[0046] The technical solution provides a speaker net fixing device, which is used to fix the speaker net 300 of the speaker, by providing a receiving cavity 110 in the frame 100 to accommodate the speaker body, and providing a first through slot 121 and a second through slot 122 on the first side wall 120 so that both ends of the speaker net 300 pass through the first side wall 120 and extend into the receiving cavity 110. By extending one end of the fixing member 200 into the receiving cavity 110 and connecting with the speaker net 300, and the other end being detachably connected with the frame 100, and fixing both ends of the speaker net 300 with the frame 100 through the fixing member 200, the fixed connection between the speaker net 300 and the frame 100 is achieved. Since the speaker mesh 300 is fixedly connected to the frame 100 by the fixing member 200, the slots of the first through slot 121 and the second through slot 122 can be set to be relatively wider. In this way, even if the speaker mesh 300 is deformed due to its excessive length, it can be inserted into the receiving slot from the first through slot 121 and the second through slot 122. Moreover, there is no need to manually bend the tongue of the speaker mesh 300 during installation, thereby improving the installation efficiency.

[0047] It should be noted that there is no limitation on the specific structure of the frame 100. In this embodiment, when the speaker net fixing device is applied to an interactive smart tablet, the frame 100 in the speaker net fixing device can be a frame 100 used to fix the display screen and the back shell and other structures in the interactive smart tablet. When connecting the speaker net 300 to the fixing device, the two ends of the speaker net 300 connected to the fixing member 200 can be bent in advance and then inserted into the first through groove 121 and the second through groove 122; or after the speaker net 300 is inserted into the first through groove 121 and the second through groove 122, the speaker net 300 can be bent using the edges of the first through groove 121 and the second through groove 122.

[0048] It should be understood that, for the two ends of the speaker mesh 300 being fixed to the frame 100 by the fixing member 200, one fixing member 200 can fix both ends of the speaker mesh 300 at the same time, or both ends of the speaker mesh 300 can be fixed to the frame 100 by one fixing member 200 respectively, or both ends of the speaker mesh 300 can be fixed to the frame 100 by multiple fixing members 200 arranged at intervals. In this embodiment, the two ends of the speaker mesh 300 are fixed to the frame 100 by multiple fixing members 200 arranged at intervals.

[0049] like Figure 7 As shown, specifically, a plurality of mounting holes 310 are configured at both ends of the speaker net 300, and the plurality of mounting holes 310 located at the same end of the speaker net 300 are arranged at intervals along the extension direction of the speaker net 300; a plurality of fixing members 200 are arranged at intervals along the extension direction of the speaker net 300, so that each mounting hole 310 corresponds to a fixing member 200. By configuring a plurality of mounting holes 310 at both ends of the speaker net 300 and making the mounting holes 310 arranged at intervals along the extension direction of the speaker net, it is convenient to connect with the fixing members 200 arranged at intervals. By having one mounting hole 310 correspond to one fixing member 200, it is beneficial to make the structure of a single fixing member 200 simpler, and it is also beneficial to avoid the speaker body.

[0050] like Figures 2 to 4As shown, specifically, in one embodiment, the frame 100 also includes a second side wall 130, a third side wall 140 and a fourth side wall 150, one end of the second side wall 130 is fixedly connected to one end of the first side wall 120; one end of the third side wall 140 is fixedly connected to the other end of the first side wall 120; the fourth side wall 150 is arranged opposite to the first side wall 120, and the two ends of the fourth side wall 150 are respectively connected to the ends of the second side wall 130 and the third side wall 140 away from the first side wall 120; the first side wall 120, the second side wall 130, the third side wall 140 and the fourth side wall 150 enclose and define the accommodating cavity 110; the fourth side wall 150 is provided with avoidance holes 151 for the fixing member 200 to pass through, and the number of avoidance holes 151 corresponds to the number of fixing members 200.

[0051] The frame 100 may be a profile formed by extrusion of an aluminum alloy, or may be a sheet metal structure formed by cold deformation of a steel plate. The first side wall 120 is arranged at an angle to the second side wall 130 and the third side wall 140. The ends of the second side wall 130 and the third side wall 140 close to the first side wall 120 are bent in a direction close to each other, and the bent portion of the second side wall 130, the first side wall 120 and the bent portion of the third side wall 140 are surrounded to define a receiving groove. When the speaker net 300 is assembled with the frame, the speaker net 300 is just located in the receiving groove, and the side of the speaker net 300 facing away from the first side wall 120 is flush with the side of the second side wall 130 and the third side wall 140 away from the fourth side wall 150. In this way, on the one hand, the speaker net 300 can be protected by the bent portions 2121 on the second side wall 130 and the third side wall 140, and on the other hand, the appearance of the speaker net 300 is more beautiful.
