Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a terminal device. Background Art

[0002] With the increasing demand for terminal devices, for example, portable notebooks are required to have outstanding sound quality in addition to being thin overall. Among them, the main structure that affects the sound quality of terminal devices such as portable notebooks is the sound cavity structure. Especially in the structural design of notebooks, in order to improve the sound quality, the sound cavity structure is made as large as possible, and the sound cavity structure is set at the bottom of the notebook, and the overall sound cavity structure is L-shaped, which matches the bottom of the notebook.

[0003] However, in order to meet users' requirements for thinner and lighter notebook designs, the area at the bottom of the notebook where the sound cavity structure can be placed is getting smaller and smaller, and the design and fixation of the sound cavity structure are limited by the size of the notebook in the thickness direction.

[0004] Usually, the sound cavity structure needs to vibrate during use. Therefore, when the sound cavity structure is fixed on the limit piece of the shell, the outer layer of the limit piece is provided with an elastic structure, such as a rubber ring or an elastic block, so as to meet the relative vibration between the sound cavity structure and the shell part of the notebook. However, this fixing method requires opening a through hole in the sound cavity structure to meet the installation of the elastic structure and the adaptation with the limit piece. Then, in the thickness direction of the notebook, the upper and lower sides of the elastic structure need to reserve a thickness of at least 1.0 mm. At the same time, in order to reduce the movement of the elastic structure on the limit piece, there will also be a corresponding limit structure on the limit piece. In this way, the superposition of the thickness of the sound cavity structure, the elastic structure and the limit piece makes it difficult to thin the corresponding position of the notebook. Summary of the invention

[0005] The embodiment of the present application provides a terminal device, which can improve the technical problem that the existing installation method of the sound cavity structure is difficult to achieve the requirement of making the terminal device light and thin.

[0006] To achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0007] The present application provides a terminal device, including a housing, a sound cavity structure, an elastic structure, a first position-limiting connection structure, and a second position-limiting connection structure;

[0008] The shell includes a bottom shell and a cover shell covering the bottom shell, and a stopper is provided on the cover shell; the bottom shell is the bottom part of the shell, which is usually used to contact the support surface, and the cover shell is the part of the shell facing the user, which is also the part opposite to the bottom shell; in a notebook, the cover shell can be installed with a keyboard, a touchpad, etc., and the bottom shell is placed on the support surface to play a supporting role;

[0009] The sound cavity structure is arranged in the face shell, and a through hole is provided in the sound cavity structure, and the through hole is used for the limiting member to pass through;

[0010] The elastic structure is placed in the through hole and sleeved on the limiting member;

[0011] The first limiting connection structure is formed between the outer side wall of the limiting member and the inner side wall of the elastic structure;

[0012] The second limiting connection structure is formed between the hole wall of the through hole and the outer side wall of the elastic structure.

[0013] Here, the limiting member is used to limit the sound cavity structure. At the same time, the elastic structure is used to ensure that relative vibration can occur between the sound cavity structure and the limiting member. The material of the elastic structure can be rubber, silicone, resin, plastic, etc.

[0014] The first position-limiting connection structure causes relative movement between the position-limiting elastic structure and the position-limiting member. Of course, the degree of limit between the two may be different according to actual use requirements. For example, under the position-limiting action of the first position-limiting connection structure, the elastic structure and the position-limiting member may move relative to each other, or, under the position-limiting action of the first position-limiting connection structure, the elastic structure and the position-limiting member may remain relatively still. Similarly, the second position-limiting connection structure causes relative movement between the position-limiting elastic structure and the sound cavity structure. Similarly, according to actual use requirements, the degree of limit between the two may be different, that is, after the position-limiting is completed, the elastic structure and the sound cavity structure may move relative to each other, or, the two may remain relatively still.

[0015] The above technical solutions in the embodiments of the present application have at least the following technical effects or advantages:

[0060] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] With the increasing demand for terminal devices, for example, portable notebooks are required to have outstanding sound quality in addition to being thin overall. Among them, the main structure that affects the sound quality of terminal devices such as portable notebooks is the sound cavity structure. Especially in the structural design of notebooks, in order to improve the sound quality, the sound cavity structure is made as large as possible, and the sound cavity structure is set at the bottom of the notebook. It can be understood that the overall sound cavity structure is L-shaped, which coincides with the right-angle bottom of the notebook.

[0062] However, in order to meet users' requirements for thinner and lighter notebook designs, the area at the bottom of the notebook where the sound cavity structure can be placed is getting smaller and smaller, and the design and fixation of the sound cavity structure are limited by the size of the notebook in the thickness direction.

[0063] Usually, the sound cavity structure needs to vibrate during use. Therefore, when the sound cavity structure is fixed on the limit piece of the shell, the outer layer of the limit piece is provided with an elastic structure, such as a rubber ring or an elastic block, so as to meet the relative vibration between the sound cavity structure and the shell part of the notebook. However, this fixing method requires opening a through hole in the sound cavity structure to meet the installation of the elastic structure and the adaptation with the limit piece. Then, in the thickness direction of the notebook, the upper and lower sides of the elastic structure need to reserve a thickness of at least 1.0 mm. At the same time, in order to reduce the movement of the elastic structure on the limit piece, there will also be a corresponding limit structure on the limit piece. In this way, the superposition of the thickness of the sound cavity structure, the elastic structure and the limit piece makes it difficult to thin the corresponding position of the notebook.

[0064] In view of this, the present application provides a terminal device, in which an elastic structure is arranged between the through hole of the sound cavity structure and the limiting member of the face shell. Specifically, a first limiting connection structure is formed between the outer wall of the limiting member and the inner wall of the elastic structure, and a second limiting connection structure is formed between the hole wall of the through hole and the outer wall of the elastic structure, and the sound cavity structure is limited in the thickness direction perpendicular to the shell of the terminal device, that is, the position where the limiting occurs is in the thickness direction perpendicular to the shell of the terminal device, then, there is a certain margin reserved in the thickness direction of the shell, so that the thickness of the shell at the fixed position of the sound cavity structure can be developed towards slimming.

[0065] The terminal device 1000 involved in the embodiments of the present application may include a handheld device, a vehicle-mounted device, a wearable device, a computing device, or other processing devices connected to a wireless modem. It may also include a cellular phone, a smart phone, a personal digital assistant (PDA) computer, a tablet computer, a laptop computer, a machine type communication (MTC) terminal, a point of sales (POS), a vehicle-mounted computer, and other terminal devices 1000 with imaging functions.

[0066] The embodiment of the present application does not impose any special restrictions on the specific form of the terminal device 1000. For the convenience of description and understanding, the following description is made by taking the terminal device 1000 as a notebook as an example.

[0067] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a notebook provided in an embodiment of the present application, wherein the notebook includes a display screen 1001 and a keyboard 1002 that can be folded relative to each other, and the two are connected by a hinge.

[0068] The keyboard 1002 includes a shell 100 and a key portion 1003 disposed on the shell 100, wherein the sound cavity structure 200 is disposed in the shell 100 and located at the bottom corner position of the shell 100, which is two right angles or approximately right angles away from one side of the display screen 1001.

[0069] Please refer to Figure 2 and Figure 3 The present application provides a terminal device 1000 , including a housing 100 , a sound cavity structure 200 , an elastic structure 300 , a first position-limiting connection structure 400 , and a second position-limiting connection structure 500 .

[0070] Among them, the shell 100 includes a bottom shell 101 and a surface shell 102 covering the bottom shell 101. It can be understood that the bottom shell 101 is the part of the terminal device 1000 that contacts the placement surface when in normal use, and the surface shell 102 is the part of the terminal device 1000 that faces the user when in normal use. For example, when the terminal device 1000 is a notebook, a keyboard, a touchpad and other input devices can be set on the surface shell 102, and the bottom shell 101 is used to contact the desktop or table when the notebook is in use to play a supporting role.

[0071] A limiting member 103 is provided on the surface shell 102 .

[0072] The limiting member 103 is convexly disposed on the front shell 102 and is located between the front shell 102 and the bottom shell 101. The limiting member 103 is used to limit the setting position of the sound cavity structure 200 in the housing 100. The structural form of the limit member 103 includes but is not limited to a limit column, a limit tube, etc., and the setting position of the limit member 103 can also be adjusted according to actual needs. For example, the limit member 103 includes a limit column, which can be located at the right angle side of the right angle bottom of the shell 100. There is enough space in the thickness direction of the shell 100 at this point, and an additional limit column can be set to limit the sound cavity structure 200. Alternatively, the limit member 103 includes a limit tube, which can be located at the top corner of the right angle bottom of the shell 100. The space in the thickness direction of the shell 100 is narrow at this point, and the additional setting of the limit member 103 is not conducive to the slimming of the shell 100 at this point. Therefore, the limit tube should coincide with the position of the threaded tube adapted for the screws at this point, that is, the limitation of the sound cavity structure 200 can be achieved, and the connection and installation requirements with fastening structures such as screws at this point can be met.

[0073] The sound cavity structure 200 is disposed in the surface shell 102 . The sound cavity structure 200 defines a through hole 201 . The through hole 201 is used for the limiting member 103 to pass through.

[0074] It can be understood that when the sound cavity structure 200 is placed in the face shell 102, its through hole 201 is adapted to the limiter 103. Of course, according to actual use requirements, the number of limiters 103 can be multiple, and at the same time, the through holes 201 adapted to the limiters 103 are also multiple. In addition, the opening direction of the through hole 201 should be through the sound cavity structure 200 along the thickness direction of the sound cavity structure 200. Here, the thickness direction of the sound cavity structure 200 should be the same as the thickness direction of the housing 100, and is also the overall thickness direction of the terminal device 1000.

[0075] The elastic structure 300 is disposed in the through hole 201 and sleeved on the limiting member 103 .

[0076] It can be understood that the sound cavity structure 200 needs to vibrate during operation, so a certain amount of clearance should be left between the sound cavity structure 200 and the stopper 103, that is, a certain amount of clearance should be formed between the inner wall of the through hole 201 and the outer wall of the stopper 103. At the same time, the sound cavity structure 200 and the stopper 103 also need to meet the requirement of soft contact, that is, they need to be connected through the elastic structure 300 to reduce the impact of the stopper 103 directly colliding with the sound cavity structure 200 that vibrates during operation and affecting the sound quality.

[0077] Here, the material of the elastic structure 300 should have a certain degree of deformability. The material of the elastic structure 300 includes but is not limited to rubber, plastic, resin, etc. At the same time, the shape structure of the elastic structure 300 can also be adjusted according to actual usage. For example, the elastic structure 300 is a closed annular structure, which is sleeved on the limit member 103. Of course, the elastic structure 300 can also include a plurality of independent elastic blocks, each of which is arranged around the circumference of the limit member 103 at intervals with the center line of the limit member 103 as the center. Here, the number of elastic blocks can be two, three or more.

[0078] The first limiting connection structure 400 is formed between the outer wall of the limiting member 103 and the inner wall of the elastic structure 300 ; the second limiting connection structure 500 is formed between the hole wall of the through hole 201 and the outer wall of the elastic structure 300 .

[0079] It can be understood that the first limiting connection structure 400 acts to cause relative movement between the limiting elastic structure 300 and the limiting member 103, so that a certain interaction force is formed between the outer wall of the limiting member 103 and the inner wall of the elastic structure 300, that is, a certain connection relationship. Of course, according to actual usage requirements, the degree of limitation and connection between the two is also different. For example, under the limiting action of the first limiting connection structure 400, relative movement can occur between the elastic structure 300 and the limiting member 103, or, under the limiting action of the first limiting connection structure 400, the elastic structure 300 and the limiting member 103 remain relatively still.

[0080] For example, when the elastic structure 300 and the limiting member 103 are able to move relative to each other, the friction coefficient between the inner wall of the elastic structure 300 and the outer wall of the limiting member 103 can be increased, for example, by changing the material of the elastic structure 300, or by providing some structural patterns on the walls of the two that can increase the friction coefficient, or by adopting an interference fit between the elastic structure 300 and the limiting member 103.

[0081] For example, a protrusion structure is provided on the inner wall of the elastic structure 300, and a concave structure is provided on the outer wall of the limiting member 103, and the protrusion structure is adapted to the concave structure. Thus, while satisfying the limiting requirements of both, a certain displacement can be retained between the elastic structure 300 and the limiting member 103.

[0082] For example, a protrusion structure is provided on the inner wall of the elastic structure 300 , and the protrusion structure directly abuts against the outer wall of the limiting member 103 . At this time, there is an interference fit between the inner wall of the elastic structure 300 and the outer wall of the limiting member 103 , and a certain amount of displacement can be retained between the elastic structure 300 and the limiting member 103 .

[0083] For example, when there is no relative movement between the elastic structure 300 and the stopper 103, that is, the elastic structure 300 and the stopper 103 remain relatively still, the elastic structure 300 can fully utilize its own deformable characteristics to meet the displacement requirements of the sound cavity structure 200 when it is working.

[0084] For example, the inner wall of the elastic structure 300 is integrally formed with the outer wall of the limiter 103, that is, the elastic structure 300 is directly connected to the outer wall of the limiter 103 by in-mold injection molding. Therefore, when the sound cavity structure 200 vibrates, the deformation of the elastic structure 300 is larger.

[0085] Similarly, the second limiting connection structure 500 acts to cause relative movement between the limiting elastic structure 300 and the sound cavity structure 200, so that a certain interaction force is formed between the outer wall of the elastic structure 300 and the inner wall of the through hole 201, that is, a certain connection relationship. Similarly, according to actual usage requirements, the degree of limitation between the two may be different, that is, after the limitation is completed, the elastic structure 300 and the sound cavity structure 200 can move relative to each other, or the two can remain relatively still.

[0086] For example, when the outer wall of the elastic structure 300 and the inner wall of the through hole 201 are able to move relative to each other, the friction coefficient between the outer wall of the elastic structure 300 and the inner wall of the through hole 201 can be increased, such as by changing the material of the elastic structure 300, or by providing some structural patterns on the walls of the two that can increase the friction coefficient, or by adopting an interference fit between the outer wall of the elastic structure 300 and the inner wall of the through hole 201.

[0087] For example, a protrusion structure is set on the outer wall of the elastic structure 300, and a concave structure is set on the inner wall of the through hole 201. The protrusion structure and the concave structure are adapted to each other. In this way, while satisfying the limitation of both, a certain displacement can be retained between the elastic structure 300 and the inner wall of the through hole 201.

[0088] For example, a protrusion structure is provided on the outer wall of the elastic structure 300, and the protrusion structure directly abuts against the inner wall of the through hole 201. At this time, there is an interference fit between the outer wall of the elastic structure 300 and the inner wall of the through hole 201, and a certain amount of displacement can be retained between the elastic structure 300 and the inner wall of the through hole 201.

[0089] For example, when there is no relative movement between the outer wall of the elastic structure 300 and the inner wall of the through hole 201, that is, the elastic structure 300 and the sound cavity structure 200 remain relatively still, the elastic structure 300 can be fully utilized to fully meet the displacement requirement of the sound cavity structure 200 when it is working.

[0090] For example, the outer wall of the elastic structure 300 and the inner wall of the through hole 201 are integrally formed, that is, the elastic structure 300 is directly connected to the through hole 201 of the sound cavity structure 200 by in-mold injection molding. Therefore, when the sound cavity structure 200 vibrates, the deformation of the elastic structure 300 is larger.

[0091] The terminal device 1000 provided in the embodiment of the present application forms a limiting relationship between the outer side wall of the limiting member 103 and the inner side wall of the elastic structure 300 through the first limiting connection structure 400, so as to avoid the limiting member 103 from forming a limit in the height direction and increasing its height, thereby satisfying that the terminal device 1000 can be thinner in its thickness direction, that is, the overall thickness of the housing 100 composed of the bottom shell 101 and the surface shell 102 can be thinner, and the second limiting connection structure 500 forms a limiting relationship between the hole wall of the through hole 201 and the outer side wall of the elastic structure 300, so as to meet the vibration requirements of the sound cavity structure 200. In this way, the terminal device 1000 provided in the present application can have a thinner overall thickness of the housing 100 on the basis of ensuring the sound quality.

[0092] Please refer to Figure 3In some embodiments, the first limiting connection structure 400 includes a first substructure 401 and a second substructure 402 that are adapted to each other, the first substructure 401 being formed on one of the outer wall of the limiting member 103 and the inner wall of the elastic structure 300, and the second substructure 402 being formed on the other of the outer wall of the limiting member 103 and the inner wall of the elastic structure 300.

[0093] It can be understood that the first substructure 401 and the second substructure 402 can be set on the outer wall of the limit member 103 or the inner wall of the elastic structure 300 according to actual usage requirements; and the first limit connection structure 400 realizes the limit connection requirement between the elastic structure 300 and the limit member 103 under the interaction of the first substructure 401 and the second substructure 402.

[0094] The first substructure 401 and the second substructure 402 are structures capable of realizing force interaction, for example, the first substructure 401 is a convex rib, and the second substructure 402 is a groove matched with the convex rib, or the first substructure 401 is a toothed structure or a wave structure, and the second substructure 402 is a toothed structure and a wave structure matched therewith. In this way, according to actual use requirements, the first substructure 401 and the second substructure 402 that are matched are selected to meet different degrees of limiting requirements between the elastic structure 300 and the limiting member 103.

[0095] For example, Figure 3 As shown, the first substructure 401 is formed on the outer wall of the limiting member 103, and the first substructure 401 is an annular groove formed on the circumferential side of the limiting member 103. The second substructure 402 is formed on the inner wall of the elastic structure 300, and the second substructure 402 is an annular rib formed on the inner wall of the elastic structure 300. The annular rib is adapted to the annular groove to form a corresponding limiting connection requirement between the elastic structure 300 and the limiting member 103.

[0096] Of course, the positions of the annular groove and the annular rib can be swapped, that is, the first substructure 401 is an annular groove formed on the inner circumference of the elastic structure 300 , and the second substructure 402 is an annular rib formed on the outer wall of the limiting member 103 .

[0097] Of course, in other embodiments, the first substructure 401 may also include an annular groove and an annular convex rib at the same time, and then the second substructure 402 includes an annular convex rib and annular groove that are compatible therewith.

[0098] Please refer to Figure 3 In some embodiments, the first substructure 401 includes a first convex portion, and the second substructure 402 includes a first concave portion; or, the first substructure 401 includes a first concave portion, and the second substructure 402 includes a first convex portion.

[0099] It can be understood that the first convex portion includes but is not limited to a convex rib, a convex point, a convex block, etc., and the first concave portion includes but is not limited to a groove, a pit, a blind hole, etc.

[0100] In this way, the first convex portion and the first concave portion form a convex-concave matching structure to meet the limiting connection requirement between the elastic structure 300 and the limiting member 103 .

[0101] In other embodiments, the first convex portion may also include convex ribs, convex points, convex blocks, etc., and the first concave portion may also include grooves, pits, blind holes, etc. that are compatible therewith.

[0102] Please refer to Figure 4 and Figure 5 In some embodiments, the first substructure 401 includes a first protrusion, the second substructure 402 is the outer wall of the limiting member 103 or the inner wall of the elastic structure 300, and the first protrusion is interference fit with the second substructure 402.

[0103] It can be understood that in this embodiment, the interference fit in the hole-shaft fit is used to limit the limiting connection between the elastic structure 300 and the limiting member 103 .

[0104] Specifically, the first convex portion includes but is not limited to a convex rib, a convex point, a convex block, etc. The second substructure 402 is the outer wall of the limiting member 103 or the inner wall of the elastic structure 300, and the first convex portion forms an interference fit with the outer wall of the limiting member 103 or the inner wall of the elastic structure 300 to meet the limiting requirement between the elastic structure 300 and the limiting member 103.

[0105] In other embodiments, the first substructure 401 is the outer side wall of the stopper 103 or the inner side wall of the elastic structure 300; the second substructure 402 is the inner side wall of the elastic structure 300 or the outer side wall of the stopper 103. That is, in this embodiment, the outer side wall of the stopper 103 and the inner side wall of the elastic structure 300 are directly used to form an interference fit to realize the limiting connection between the elastic structure 300 and the stopper 103.

[0106] Please refer to Figure 6 In some embodiments, the first substructure 401 is one of the outer wall of the limit member 103 and the inner wall of the elastic structure 300, and the second substructure 402 is the other of the outer wall of the limit member 103 and the inner wall of the elastic structure 300, and the first substructure 401 and the second substructure 402 are integrally formed.

[0107] It can be understood that in this embodiment, the first substructure 401 and the second substructure 402 can be the outer wall of the limit member 103 and the inner wall of the elastic structure 300 respectively. The two side walls are connected by one-piece molding to form a bonding force, and this bonding force can be achieved by in-mold injection molding. In this way, there is no relative displacement between the limit member 103 and the elastic structure 300, and the deformation characteristics of the elastic structure 300 itself are relied upon to provide the corresponding vibration requirements for the sound cavity structure 200.

[0108] Specifically, the first substructure 401 and the second substructure 402 correspond to the outer wall of the limiting member 103 and the inner wall of the elastic structure 300, respectively, or correspond to the inner wall of the elastic structure 300 and the outer wall of the limiting member 103, respectively, and by connecting the first substructure 401 and the second substructure 402 in an integrally formed manner, the elastic structure 300 is fixed on the limiting member 103, thereby greatly improving the limiting requirements between the elastic structure 300 and the limiting member 103.

[0109] Please refer to Figure 3 In some embodiments, the second limiting connection structure 500 includes a third substructure 501 and a fourth substructure 502 that are adapted to each other, the third substructure 501 being formed on one of the hole wall of the through hole 201 and the outer wall of the elastic structure 300, and the fourth substructure 502 being formed on the other of the hole wall of the through hole 201 and the outer wall of the elastic structure 300.

[0110] It can be understood that the third substructure 501 and the fourth substructure 502 can be set on the outer wall of the elastic structure 300 or on the inner wall of the through hole 201 according to actual usage requirements; and, the second limiting connection structure 500 realizes the limiting connection requirement between the elastic structure 300 and the inner wall of the through hole 201 under the interaction of the third substructure 501 and the fourth substructure 502.

[0111] The third substructure 501 and the fourth substructure 502 can be arranged on the outer wall of the elastic structure 300 or on the hole wall of the through hole 201 according to actual use requirements; the third substructure 501 and the fourth substructure 502 are structures that can realize the interaction of forces, for example, the third substructure 501 is a convex rib, and the fourth substructure 502 is a groove that matches the convex rib, or the third substructure 501 is a toothed structure or a wave structure, and the fourth substructure 502 is a toothed structure and a wave structure that match them. In this way, according to actual use requirements, the third substructure 501 and the fourth substructure 502 that match each other are selected to meet the different degrees of limit requirements between the elastic structure 300 and the through hole 201.

[0112] For example, Figure 3As shown, the third substructure 501 is formed on the outer wall of the elastic structure 300, and the third substructure 501 is an annular groove formed on the circumferential side of the elastic structure 300. The second substructure 402 is formed on the inner wall of the through hole 201, and the second substructure 402 is an annular convex rib formed on the inner wall of the through hole 201. The annular convex rib is adapted to the annular groove to form a corresponding limiting connection requirement between the elastic structure 300 and the inner wall of the through hole 201.

[0113] Of course, the positions of the annular groove and the annular rib can be swapped, that is, the third substructure 501 is an annular groove formed on the inner wall of the through hole 201, and the fourth substructure 502 is an annular rib formed on the outer wall of the elastic structure 300.

[0114] Of course, in other embodiments, the third substructure 501 may also include an annular groove and an annular convex rib at the same time, and then the fourth substructure 502 includes an annular convex rib and annular groove that are compatible therewith.

[0115] Please refer to Figure 3 In some embodiments, the third substructure 501 includes a second convex portion, and the fourth substructure 502 includes a second concave portion; or, the third substructure 501 includes a second concave portion, and the fourth substructure 502 includes first and second convex portions.

[0116] It can be understood that the second convex portion includes but is not limited to a convex rib, a convex point, a convex block, etc., and the second concave portion includes but is not limited to a groove, a pit, a blind hole, etc.

[0117] In this way, the second convex portion and the second concave portion form a convex-concave matching structure to meet the limiting requirement between the elastic structure 300 and the through hole 201 .

[0118] In other embodiments, the second convex portion may also include convex ribs, convex points, convex blocks, etc., and the second concave portion may also include grooves, pits, blind holes, etc. that are compatible with the second convex portion.

[0119] Please refer to Figure 7 and Figure 8 In some embodiments, the third substructure 501 includes a second protrusion, the fourth substructure 502 is a hole wall of the through hole 201 or an outer side wall of the elastic structure 300 , and the second protrusion is interference fit with the fourth substructure 502 .

[0120] It can be understood that in this embodiment, the interference fit in the hole-shaft fit is used to define the limiting connection between the elastic structure 300 and the inner wall of the through hole 201 .

[0121] Specifically, the second convex portion includes but is not limited to a convex rib, a convex point, a convex block, etc. The fourth substructure 502 is the outer wall of the elastic member or the inner wall of the through hole 201, and the second convex portion forms an interference fit with the outer wall of the elastic member or the inner wall of the through hole 201 to meet the limit requirement between the elastic structure 300 and the inner wall of the through hole 201.

[0122] In other embodiments, the third substructure 501 is the outer wall of the elastic structure 300 or the inner wall of the through hole 201; the fourth substructure 502 is the inner wall of the through hole 201 or the outer wall of the elastic structure 300. That is, in this embodiment, the outer wall of the elastic structure 300 and the inner wall of the through hole 201 are directly used to form an interference fit to achieve the limiting connection between the elastic structure 300 and the inner wall of the through hole 201.

[0123] Please refer to Fig. 9 In some embodiments, the third substructure 501 is one of the hole wall of the through hole 201 and the outer wall of the elastic structure 300, the fourth substructure 502 is the other of the hole wall of the through hole 201 and the outer wall of the elastic structure 300, and the first substructure 401 and the second substructure 402 are integrally formed.

[0124] It can be understood that in this embodiment, the third substructure 501 and the fourth substructure 502 correspond to the outer wall of the elastic structure 300 and the hole wall of the through hole 201, respectively, or correspond to the hole wall of the through hole 201 and the outer wall of the elastic structure 300, respectively, and by connecting the third substructure 501 and the fourth substructure 502 in an integrally formed manner, the elastic structure 300 is fixed on the through hole 201, thereby greatly improving the limiting requirements between the elastic structure 300 and the sound cavity structure 200.

[0125] Specifically, the third substructure 501 and the fourth substructure 502 correspond to the outer wall of the elastic member and the inner wall of the through hole 201, respectively, or correspond to the inner wall of the through hole 201 and the outer wall of the elastic member, respectively, and by connecting the third substructure 501 and the fourth substructure 502 in an integrally formed manner, the elastic structure 300 is fixed on the sound cavity structure 200, thereby greatly improving the limiting requirements between the elastic structure 300 and the sound cavity structure 200.

[0126] Please refer to Figure 3 In some embodiments, the thickness of the elastic structure 300 is less than or equal to the height of the limiting member 103 .

[0127] It can be understood that by limiting the relationship between the thickness of the elastic structure 300 and the height of the limiter 103 to reduce the influence of the thickness of the elastic structure 300 on the assembly of the shell 100, the thickness of the shell 100 at the installation point of the sound cavity structure 200 can be further reduced.

[0128] Please refer to Figure 3 In some embodiments, the limiting member 103 includes a limiting column 1031 , and the terminal device 1000 further includes a fastener 600 , which is passed through the bottom shell 101 and is adapted to the limiting column 1031 .

[0129] It can be understood that the fastener 600 is matched with the limiting column 1031 to increase the connection position between the bottom shell 101 and the front shell 102, so as to improve the connection stability between the bottom shell 101 and the front shell 102. Specifically, the fastener 600 can be a screw, and a threaded hole is provided in the limiting column 1031. The screw knob is inserted into the threaded hole to achieve the connection between the bottom shell 101 and the front shell 102.

[0130] For example, the top angle position of the bottom angle of the shell 100 is the thinnest position of the shell 100. In addition to meeting the requirements of setting and fixing the sound cavity structure 200, it is also necessary to meet the connection requirements of the bottom shell 101 and the front shell 102. Therefore, a threaded tube column is usually set on the front shell 102 at this location, and the bottom shell 101 and the threaded tube column are fastened in sequence by screws to achieve the connection between the two. Then, on this basis, the limiting tube column 1031 of the present application and the setting of the threaded tube column on the front shell 102 are overlapped, that is, the limiting tube column 1031 provided in the present application can limit the sound cavity structure 200, and is also used to meet the installation requirements of fasteners 600, such as screws, which greatly saves the space in the thickness direction of the notebook, so that the notebook can have enough space to install and limit the sound cavity structure 200 within a limited space.

[0131] Specifically, please refer to Figure 3 In a specific embodiment, the terminal device 1000 includes a housing 100 , a sound cavity structure 200 , an elastic structure 300 , a first limiting connection structure 400 , a second limiting connection structure 500 , and a fastener 600 .

[0132] Specifically, the housing 100 includes a bottom shell 101 and a surface shell 102 covering the bottom shell 101 . A limiting column 1031 is provided on the surface shell 102 . The fastener 600 passes through the bottom shell 101 and is adapted to the limiting column 1031 .

[0133] The sound cavity structure 200 is disposed in the face shell 102 . The sound cavity structure 200 defines a through hole 201 . The through hole 201 is used for allowing the limiting tube column 1031 to pass through.

[0134] The first limiting connection structure 400 is formed between the outer wall of the limiting member 103 and the inner wall of the elastic structure 300. The first limiting connection structure 400 includes a first substructure 401 and a second substructure 402 that are adapted to each other. The first substructure 401 is an annular groove formed on the outer wall of the limiting column 1031, and the second substructure 402 is an annular convex rib formed on the inner wall of the elastic structure 300.

[0135] The second limiting connection structure 500 is formed between the hole wall of the through hole 201 and the outer wall of the elastic structure 300; the second limiting connection structure 500 includes a third substructure 501 and a fourth substructure 502 that are adapted to each other, the third substructure 501 is an annular groove formed on the outer wall of the elastic structure 300, and the fourth substructure 502 is an annular convex rib formed on the inner wall of the through hole 201.

[0136] The thickness of the elastic structure 300 is equal to the height of the limiting member 103 .

[0137] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
