Description

Technical Field

[0001] The utility model relates to the technical field of magnetic attraction structures, in particular to a box and a speaker with a magnetic attraction fixing structure. Background Art

[0002] A magnetic attraction structure is set on electronic products such as speakers, and the speakers and other electronic products are magnetically attracted to the magnetic panel through the magnetic attraction structure. Most existing electronic products such as speakers have a single magnet embedded directly at the bottom of the speaker. In order to maintain the overall stability of electronic products such as speakers, the single magnet has a large size and weight. For electronic products such as speakers, the structure that fixes the single magnet needs to withstand a greater pulling force. When electronic products such as speakers are subjected to multiple pulling forces, stress is generated, which reduces the service life. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

[0004] The technical solutions adopted by the present invention to solve the above technical problems are as follows:

[0005] On the one hand, the present invention provides a box with a magnetic fixing structure, including a first shell, a second shell and a magnetic fixing structure. The bottom of the first shell is provided with multiple installation grooves, and the multiple magnetic fixing structures are respectively arranged in the multiple installation grooves. The second shell is arranged on the outside of the first shell to limit the magnetic fixing structure from detaching from the first shell.

[0006] Optionally, the mounting groove includes a first mounting groove and a plurality of second mounting grooves, and one end of each of the plurality of second mounting grooves is connected to the bottom of the first mounting groove.

[0007] Optionally, the magnetic fixing structure includes a magnet bracket and a magnet assembly, a magnet slot is provided on one side of the magnet bracket, the magnet slot is arranged in the first mounting slot, and the magnet assembly is embedded in the magnet slot.

[0008] Optionally, a plurality of connecting members are provided on the other side of the magnet bracket, and the plurality of connecting members are respectively arranged in a plurality of the second mounting grooves.

[0009] Optionally, a limiting member is provided at the open end of the magnet slot, and the limiting member includes a first limiting member, one end of the first limiting member is connected to one end of the magnet slot, and the other end of the first limiting member is bent and covers the surface of the magnet assembly.

[0010] Optionally, two first limiting members are provided, and the two first limiting members are respectively connected to the two ends of the magnet slot.

[0011] Optionally, the limiting member further includes a second limiting member, both ends of which are respectively connected to two side walls of the magnet slot, and the second limiting member is arranged parallel to the first limiting member.

[0012] Optionally, the magnet assembly includes a stacked magnet and an iron sheet, one side of the iron sheet abuts against the bottom of the magnet slot, the other side of the iron sheet abuts against one side of the magnet, and the other side of the magnet contacts the limiter.

[0013] Another aspect of the present invention provides a speaker, comprising the box body with the magnetic fixing structure as described above.

[0014] Optionally, an acoustic structure is provided inside the first shell.

[0015] According to the box body with a magnetic fixing structure provided by the utility model, a plurality of mounting grooves are provided at the bottom of the first shell, and the plurality of magnetic fixing structures are respectively provided in the plurality of mounting grooves. The plurality of magnetic fixing structures are fixedly connected to the plurality of mounting grooves, thereby reducing the pulling force that a single mounting groove needs to bear to fix the magnetic fixing structure, and also reducing the strength requirement for the first shell, saving costs.

[0025] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1 、 Figure 3-Figure 4As shown, in one embodiment, the utility model provides a box body with a magnetic fixing structure, including a first shell 21, a second shell 23 and a magnetic fixing structure 1. The bottom of the first shell 21 is provided with multiple installation grooves 22, and the multiple magnetic fixing structures 1 are respectively arranged in the multiple installation grooves 22. The second shell 23 is arranged on the outside of the first shell 21 to limit the magnetic fixing structure 1 from being separated from the first shell 21.

[0027] Specifically, the first housing 21 is made of ABS material, and the second housing 23 is made of TPU material by injection molding;

[0028] There are at least two mounting slots 22 . In a preferred embodiment, there are at least four mounting slots 22 , distributed at the four corners of the bottom of the first shell 21 . Similarly, there are four magnetic fixing structures 1 , which are respectively arranged in multiple mounting slots 22 .

[0029] Specifically, by providing multiple mounting grooves 22 at the bottom of the first shell 21, multiple magnetic fixing structures 1 are respectively provided in the multiple mounting grooves 22. By fixedly connecting the multiple magnetic fixing structures 1 to the multiple mounting grooves 22, the pulling force that a single mounting groove 22 needs to bear for fixing the magnetic fixing structure 1 is reduced, and the strength requirement for the first shell 21 is also reduced, thereby saving costs.

[0030] Furthermore, the box is magnetically attracted to the magnetic panel through the magnetic structure. When the magnetic structure is magnetically attracted and detached from the magnetic panel multiple times, stress will be generated in the installation slot 22 where the magnetic fixing structure 1 is installed, resulting in a loose connection between the magnetic structure and the installation slot 22, resulting in the problem of falling off, thereby reducing the service life; the present application sets a second shell 23, and the inner bottom plate of the second shell 23 abuts against the magnetic fixing structure 1, thereby limiting the magnetic fixing structure 1, preventing the magnetic fixing structure 1 from falling off from the installation slot 22, and extending the service life of the magnetic fixing structure 1; in addition, the magnetic fixing structure 1 allows the box itself to be stably placed on a magnetic panel at a certain angle to the ground plane, without falling off, and without the need for additional components to assist in fixing.

[0031] like Figure 3-Figure 4 As shown, in one embodiment, the mounting groove 22 includes a first mounting groove 221 and a plurality of second mounting grooves 222 , and one end of each of the plurality of second mounting grooves 222 is communicated with the bottom of the first mounting groove 221 .

[0032] Specifically, the first mounting groove 221 and the second mounting groove 222 are used to fix the magnetic fixing structure 1 ; a plurality of mounting grooves 22 are provided at the bottom of the first shell 21 , and the shapes of the plurality of mounting grooves 22 may be the same or different.

[0033] like Figure 2As shown, in one embodiment, the magnetic fixing structure 1 includes a magnet bracket 11 and a magnet assembly 12. A magnet slot 111 is provided on one side of the magnet bracket 11. The magnet slot 111 is arranged in the first mounting slot 221, and the magnet assembly 12 is embedded in the magnet slot 111.

[0034] Specifically, the outer wall of the magnet slot 111 contacts the inner wall of the first mounting slot 221, thereby limiting and fixing the magnet slot 111;

[0035] Furthermore, a groove is provided on the side wall of the magnet slot 111 , and an insert is provided on the outer wall of the magnet slot 111 at a position corresponding to the groove. The insert is embedded in the groove, thereby further limiting and fixing the magnet slot 111 .

[0036] like Figure 2-Figure 4 As shown, in one embodiment, a plurality of connecting members 113 are provided on the other side of the magnet bracket 11 , and the plurality of connecting members 113 are respectively disposed in the plurality of second mounting grooves 222 .

[0037] Specifically, multiple connecting parts 113 are arranged at the outer bottom of the magnet groove 111 and extend along the bottom of the vertical magnet groove 111. The length direction of multiple second mounting grooves 222 also extends along the direction perpendicular to the bottom of the first mounting groove 221. Multiple connecting parts 113 are embedded in the second mounting grooves 222 one by one to limit and fix the magnetic fixing structure 1.

[0038] Furthermore, multiple connecting members 113 are obliquely arranged on the outer side wall of the magnet slot 111 or the outside of the bottom of the magnet slot 111, and multiple second mounting slots 222 are also obliquely arranged on the outer side wall of the first mounting slot 221 or the bottom of the first mounting slot 221 in the length direction. Multiple connecting members 113 are embedded one by one in the second mounting slot 222. The connecting members 113 are obliquely arranged, which can increase the friction between the magnetic fixing structure 1 and the mounting slot 22, and at the same time further reduce the pulling force that a single mounting slot 22 needs to bear to fix the magnetic fixing structure 1, and also reduce the strength requirement for the first shell 21, saving costs, and further limiting and fixing the magnetic fixing structure 1.

[0039] like Figure 2 As shown, in one embodiment, a limiting member 112 is provided at the open end of the magnet slot 111, and the limiting member 112 includes a first limiting member 1121, one end of the first limiting member 1121 is connected to one end of the magnet slot 111, and the other end of the first limiting member 1121 is bent and covers the surface of the magnet assembly 12.

[0040] Specifically, the first limiting member 1121 is used to fix the end of the magnet assembly 12 to prevent the magnet assembly 12 from being separated from the magnet slot 111 .

[0041] like Figure 2As shown, in one embodiment, two first limiting members 1121 are provided, and the two first limiting members 1121 are respectively connected to the two ends of the magnet slot 111 .

[0042] Specifically, the two first limit members 1121 are used to fix the two ends of the magnet assembly 12, so that the two ends of the magnet assembly 12 are subjected to balanced force, reducing the pulling force that the magnet slot 111 needs to withstand to fix the magnetic attraction assembly, and also reducing the strength requirements of the magnet slot 111, thereby preventing the magnet assembly 12 from detaching from the magnet slot 111.

[0043] like Figure 2 As shown, in one embodiment, the limiting member 112 further includes a second limiting member 1122 , both ends of the second limiting member 1122 are respectively connected to the two side walls of the magnet slot 111 , and the second limiting member 1122 is arranged parallel to the first limiting member 1121 .

[0044] Specifically, the second limit member 1122 is used to fix the middle part of the magnet assembly 12, so that the magnet assembly 12 is subjected to balanced force, reducing the pulling force that the magnet slot 111 needs to bear to fix the magnetic attraction assembly, and also reducing the strength requirement for the magnet slot 111, thereby preventing the magnet assembly 12 from detaching from the magnet slot 111.

[0045] like Figure 2 As shown, in one embodiment, the magnet assembly 12 includes a stacked magnet 121 and an iron sheet 122, one side of the iron sheet 122 abuts against the bottom of the magnet slot 111, the other side of the iron sheet 122 abuts against one side of the magnet 121, and the other side of the magnet 121 contacts the limiter 112.

[0046] Specifically, the length of the magnet 121 is 42 mm, the width of the magnet 121 is 10 mm, the thickness of the magnet 121 is 6 mm, the length of the iron sheet 122 is 42 mm, the width of the iron sheet 122 is 10 mm, and the thickness of the iron sheet 122 is 1 mm. The setting of the iron sheet 122 can enhance the magnetism of the magnet 121.

[0047] The installation method of the present application is: stack the magnet 121 and the iron sheet 122 into the mold of the magnetic fixing structure 1, and injection mold to form the magnetic fixing structure 1; then place the magnetic fixing structure 1 into the mold of the first shell 21 to form the position of the installation groove 22, and use ABS material to injection mold to form the first shell 21. At this time, the magnetic fixing structure 1 has been connected to the installation groove 22 of the first shell 21 as a whole. Then, place the first shell 21 into the mold of the second shell 23, and use TPU material to injection mold the outside of the first shell 21 to form the second shell 23. Finally, magnetize the magnet 121 to form a box with a magnetic fixing structure 1.

[0048] On the other hand, the present invention provides a speaker, including a box body with the magnetic fixing structure 1 as described above.

[0049] Specifically, the first shell 21 and the second shell 23 are equivalent to the outer shell of the speaker.

[0050] Furthermore, the box with the magnetic fixing structure 1 of the present application can also be used in other electronic products.

[0051] In one embodiment, an acoustic structure is disposed inside the first housing 21 .

[0052] The speaker of the present application can be magnetically attracted to the magnetic panel through the magnetic fixing structure 1 provided at the bottom of the first shell 21. The magnetic fixing structure 1 allows the speaker itself to be stably placed on the magnetic panel at a certain angle to the ground plane without falling off, and does not require additional components to assist in fixing. It has the advantages of simple structure and good magnetic effect.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
