[0038] Figure 1 Schematically shows an overall structural view of a housing structure 100 according to an embodiment of the present invention. Figure 2 For Figure 1 the top view structural view of the housing structure 100 in Figure 3 For Figure 2 the sectional structural view of the housing structure 100 in the A-A direction of Figure 5 For Figure 1 the exploded structural view of the housing structure 100 in Figure 1 [[ID=2,4]]
[0036] , 2 As shown in FIGS. 4 and 5, the present utility model provides a housing structure 100 and a loudspeaker. The housing structure 100 in the present utility model includes a first housing 10 and a second housing 20. The first housing 10 and the second housing 20 are snap-fitted, and the first housing 10 and the second housing 20 enclose a receiving cavity 50. An annular groove 11 is provided at the edge position of the side of the first housing 10 facing the second housing 20. An annular elastic member 30 is provided in the annular groove 11. An annular boss 21 is provided at the edge position of the side of the second housing 20 facing the first housing 10. The annular boss 21 is inserted into the annular groove 11 and abuts against the annular elastic member 30, so that the annular elastic member 30 fills the annular groove 11.
[0039] According to the technical solution of the present utility model, the receiving cavity 50 formed by enclosing the first housing 10 and the second housing 20 is used to accommodate the loudspeaker module. In the state where the first housing 10 and the second housing 20 are snap-fitted, the annular boss 21 of the second housing 20 is inserted into the annular groove 11 of the first housing 10 and abuts against the annular elastic member 30. Since the elastic member itself has elasticity and can undergo elastic deformation, the annular elastic member 30 subjected to the abutting force can fill the annular groove 11 to form a sealing structure, preventing impurities such as liquid outside the housing structure 100 from entering the receiving cavity 50 through the gap between the boss and the annular groove 11, and improving the sealing performance and reliability.
[0040] In some embodiments of the present utility model, as Figure 3 and 4 shown, along the direction of the first housing 10 facing the second housing 20, the width of the annular groove 11 increases in its own radial direction. In this embodiment, the cross-section of the annular groove 11 in its own radial direction is a trapezoidal surface. Along the direction of the first housing 10 facing the second housing 20, the length of the trapezoidal surface in the own radial direction of the annular groove 11 increases, indicating that the length of the bottom of the annular groove 11 in the radial direction is less than the length of the notch of the annular groove 11 in the radial direction. When the annular elastic member 30 is placed in the annular groove 11, the closer the annular elastic member 30 is to the bottom of the annular groove body, the closer the clamping force between the annular elastic member 30 and the annular groove 11 is, and the clamping and fixing between the annular elastic member 30 and the annular groove 11 can be realized. When the annular boss 21 is inserted into the annular groove 11, the annular boss 21 can better apply force to the annular elastic member 30, so that the annular elastic member 30 fills the annular groove 11, and the sealing performance between the first housing 10 and the second housing 20 is improved.
[0041] In some embodiments of the present utility model, as Figure 3 and 4As shown, the minimum width of the annular groove 11 in its radial direction is l, the annular elastic member 30 is in a ring structure, and the width of the annular elastic member 30 in its radial direction is D, where l < D. In this embodiment, the above setting can make the width of the bottom position of the annular groove 11 in its radial direction smaller than the width of the annular elastic member 30 in its radial direction, which can ensure that when the annular elastic member 30 reaches the bottom position of the annular groove 11, it remains clamped and fixed with the annular groove 11. Before the annular boss 21 is inserted into the annular groove 11, a certain pre-tightening force is provided between the annular groove 11 and the annular elastic member 30, which is convenient for the subsequent annular boss 21 to extrude the annular elastic member 30, so that the annular elastic member 30 fills the annular groove 11, improving the sealing performance between the first housing 10 and the second housing 20.
[0042] In some embodiments of the present utility model, as Figure 3 and 4 shown, the depth of the annular groove 11 is H, the minimum width of the annular groove 11 in its radial direction is l, and the maximum width of the annular groove 11 in its radial direction is L, where 0.5L < l < 0.7H. In this embodiment, the above setting can make the cross-section of the annular groove 11 along its axis tend to be square, and thus can better match the circular structure of the annular elastic member 30. When the annular elastic member 30 is placed in the annular groove 11, it can not only ensure that the annular elastic member 30 is placed in the annular groove 11, but also make there be a certain clamping force between the annular groove 11 and the annular elastic member 30, improving the reliability.
[0043] In some embodiments of the present utility model, as Figure 3 and 4 shown, the depth of the annular groove 11 is H, the annular elastic member 30 is in a ring structure, and the width of the annular elastic member 30 in its radial direction is D, 0.7D < H < D. In this embodiment, the above setting can make part of the annular elastic member 30 exposed outside the annular groove 11 after the annular elastic member 30 is placed in the annular groove 11. When the annular boss 21 extrudes the annular elastic member 30, since the annular elastic member 30 itself can undergo elastic deformation, part of the annular elastic member 30 can be compressed into the annular groove 11, so that the annular groove 11 is filled with all the annular elastic members 30, reducing the gap in the annular groove 11 and greatly improving the sealing performance between the annular boss 21 and the annular groove 11.
[0044] In some embodiments of the present utility model, as Figure 3 and 4As shown, along the direction of the first housing 10 towards the second housing 20, the width of the annular boss 21 increases in its own radial direction. In this embodiment, the above setting enables the side of the annular boss 21 facing the bottom of the annular groove 11 to have a tip structure, which can accurately and powerfully apply force to the annular elastic member 30, and can also apply force to the middle position of the annular elastic member 30, so that the deformation direction of the annular elastic member 30 extends in the radial direction of the annular groove 11 itself, which helps the annular elastic member 30 to fill the gap in the radial direction of the annular groove 11, thereby reducing the gap of the annular groove 11 and greatly improving the sealing performance between the annular boss 21 and the annular groove 11.
[0045] In some embodiments of the present utility model, as Figure 3 and 4 shown, along the direction of the first housing 10 towards the second housing 20, the height of the annular boss 21 is h, and the depth of the annular groove 11 is H, where 0.5H < h < 0.7H. In this embodiment, the above setting can ensure that after the annular boss 21 is completely inserted into the annular groove 11, it will not contact the bottom of the annular groove 11, so that the annular elastic member 30 will not be damaged due to excessive extrusion, such as cracking, and the service life and reliability of the annular elastic member 30 are improved.
[0046] In some embodiments of the present utility model, the annular elastic member 30 is a silicone member or a rubber member. In this embodiment, silicone has excellent elasticity, can absorb a large amount of impact energy, and at the same time maintains a soft touch, which is very suitable for occasions that require sealing, shock absorption or comfortable contact. Applying the silicone member to this embodiment, under the extrusion of the annular boss 21, it can better deform in the annular groove 11 and fill the annular groove 11 as much as possible, thereby ensuring the sealing performance between the first housing 10 and the second housing 20.
[0047] In some embodiments of the present utility model, as Figure 5 shown, the first housing 10 and the second housing 20 are detachably connected. In this embodiment, the first housing 10 and the second housing 20 are connected by bolts 40, and the connection strength of the bolt 40 connection is relatively high. And it is easy to disassemble and replace. When maintenance or component replacement is required, the bolt 40 can be conveniently disassembled for maintenance or replacement work, and then reassembled.
[0048] The present utility model also proposes a loudspeaker, including:
[0049] A housing structure 100, and the housing structure 100 is the above-mentioned housing structure 100;
[0050] The speaker module is disposed in the accommodation cavity 50 of the housing structure 100.
[0051] According to the technical solution of the present utility model, the accommodation cavity 50 formed by enclosing the first housing 10 and the second housing 20 is used to accommodate the speaker module. In the state where the first housing 10 and the second housing 20 are buckled, the annular boss 21 of the second housing 20 is inserted into the annular groove 11 of the first housing 10 and abuts against the annular elastic member 30. Since the elastic member itself has elasticity and can undergo elastic deformation, the annular elastic member 30 subjected to the abutting force can be filled in the annular groove 11 to form a sealing structure, preventing impurities such as liquid outside the housing structure 100 from entering the accommodation cavity 50 through the gap between the boss and the annular groove, thereby improving the sealing performance and reliability.
[0052] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered by the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
