Description

Technical Field

[0001] This application relates to the field of displays, and more particularly to a speaker mounting structure and a display device. Background Technology

[0002] The speaker is a core component of a monitor's audio output, and its assembly quality directly affects sound quality and the pass rate. Currently, the methods for fixing speakers to the monitor casing are: first, screw fastening. However, due to the small size and weak rigidity of speakers, tightening screws can easily lead to uneven stress, causing speaker deformation, diaphragm imbalance, and irreversible damage to sound quality or even failure; second, soldering. While this avoids the stress problem, it suffers from low efficiency, unpleasant odors that can harm health, and the risk of improper assembly leading to cavity seal failure. Furthermore, irreversible fastening can render the entire speaker and casing unusable, increasing costs. Therefore, optimizing speaker assembly is a problem that urgently needs to be solved. Utility Model Content

[0003] This application provides a speaker fixing structure and a display device to solve the problems of uneven force distribution leading to component damage, low efficiency, health hazards, sealing failure, and irreversible fixing increasing costs in existing speaker assemblies.

A limiting component is disposed on the rear cover and arranged around the sound guide frame. The limiting component abuts against multiple sides of the speaker to restrict the speaker from moving in a plane parallel to the rear cover. A pressing component is disposed on the rear cover. The pressing component elastically presses against the speaker so that the speaker is pressed against the sealing surface, and the speaker, the sound guide frame and the rear cover together form a sound guide cavity.

[0005] In some embodiments, the limiting component includes: The first limiting part is disposed on both sides of the sound guide frame in the length direction and transitions with the two sides of the speaker in the length direction; The second limiting part is disposed on one side of the sound guide frame in the height direction and is clearance-fitted with one side of the speaker in the height direction; The third limiting part is disposed on the other side of the sound guide frame in the height direction, and transitions with the other side of the speaker in the height direction, and is used to determine the reference position of the speaker in the height direction.

[0006] In some embodiments, both the first limiting portion and the second limiting portion include a limiting member and a main limiting surface and a guide surface disposed on the limiting member; The limiting member is connected to the outer wall of the sound guide frame; the main limiting surface faces the sound guide frame and is used to abut against the side of the speaker; the guide surface is connected to the main limiting surface and is inclined in the width direction away from the sound guide frame to guide the speaker to be installed.

[0007] In some embodiments, the clamping assembly includes a first clamping member disposed on both sides of the sound guide in the length direction and used to apply an elastic clamping force to the stepped portion of the speaker.

[0008] In some embodiments, the first clamping member includes: The support column is connected at one end to the rear cover; A first cantilever is disposed at the end of the support column away from the rear cover. The first cantilever includes a bent portion and a pressing slope. The bent portion is inclined toward the sound guide in the width direction. The pressing slope is disposed at the free end of the bent portion to press the stepped portion of the speaker. An operating component is located on the side of the bent portion away from the sound guide frame, and is used to apply external force to cause the first cantilever to elastically deform, thereby releasing the pressure of the clamping inclined surface on the speaker.

[0009] In some embodiments, the clamping assembly further includes a second clamping member, which is spaced apart from the first clamping member in the height direction and is used to apply an elastic clamping force to one end of the speaker away from the sound guide frame.

[0010] In some embodiments, the second clamping member includes: A second cantilever is provided on the rear cover, and the second cantilever is provided with a through hole extending through the width direction; A clamping buckle is protruding on the side of the second cantilever facing the sound guide frame to clamp the end of the speaker away from the sound guide frame.

[0011] In some embodiments, a fixing cavity is provided on the side of the back cover facing the display surface of the display device, the sound guide is housed in the fixing cavity, and the bottom of the sound guide is connected to the bottom of the fixing cavity; The bottom of the sound guide frame is provided with a plurality of sound guide holes that pass through in the height direction, and the rear cover is provided with a plurality of sound outlet holes that pass through in the height direction. The plurality of sound outlet holes correspond one-to-one with the plurality of sound guide holes, and the sound outlet holes are connected to the corresponding sound guide holes to form a sound guide channel.

[0012] In some embodiments, the third limiting part and the second pressing member are both disposed at the bottom of the fixed cavity; the sound guide, the third limiting part, and the second pressing member are arranged sequentially in the width direction, and the top of the third limiting part is provided with a secondary limiting surface.

[0013] Secondly, this application provides a display device including a speaker fixing structure as described in the first aspect.

[0014] The technical solutions provided in this application have the following advantages compared with the prior art: The speaker fixing structure provided in this application embodiment, by arranging the limiting component around the sound guide frame and abutting against multiple sides of the speaker, forms a limiting component in a plane parallel to the rear cover to prevent the speaker from shifting in the plane. The pressing component applies an elastic pressing force to the speaker, pressing the speaker against the sealing surface of the sound guide frame. The sound guide cavity formed by the speaker, sound guide frame and rear cover together effectively avoids the sealing failure problem caused by human experience deviation in existing hot melt assembly, prevents sound wave leakage to ensure sound effect stability, and achieves saturated sound transmission. By arranging the limiting components around the sound guide frame, it can abut against multiple sides of the speaker, achieving limitation in the length and height directions. At the same time, the elastic clamping force of the clamping components can avoid uneven force when tightening screws, preventing speaker shell distortion and diaphragm imbalance, fundamentally solving the problem of speaker deformation and sound quality damage caused by existing screw fixation. During assembly, the limiting components can quickly position and elastically fix the clamping components, eliminating the need for point-by-point heating and curing with hot melt or point-by-point operation of screws, thus improving assembly efficiency. Moreover, the elastic clamping force applied by the clamping components is fault-tolerant, avoiding the irreversible damage to the speaker and back cover caused by hot melt, improving yield and saving costs. In addition, there is no need for hot melt operation with a soldering iron, avoiding the health hazards of hot glue odor to operators. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0022] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0023] The speaker is a core component of a monitor's audio output, and its assembly quality directly affects sound quality and yield rate. Currently, there are two common methods for fixing speakers to the monitor housing: the first is screw fastening, but due to the small size and weak rigidity of speakers, uneven force during screw tightening can easily occur, leading to speaker housing distortion and deformation, disrupting the internal diaphragm balance, causing irreversible damage to frequency response and sound quality, and even causing speaker failure. The second method is soldering, which avoids the force problem but has significant drawbacks: firstly, the soldering iron's point-to-point heating and curing process is time-consuming, resulting in low assembly efficiency and difficulty in mass production; secondly, the odor from the hot glue produced at high temperatures is harmful to operator health and does not meet environmental protection requirements; thirdly, assembly accuracy relies on manual experience, and incomplete melting or misalignment can lead to improper assembly, failing to achieve a proper speaker cavity seal and weakening sound quality; fourthly, soldering is irreversible, and assembly problems can lead to the scrapping of the entire speaker and back cover housing, increasing manufacturing costs and defect rate. Therefore, optimizing speaker assembly is an urgent problem to be solved.

[0024] In response to the above technical problems, such as Figures 1-5 , Figures 8-10 As shown, this application provides a speaker fixing structure 2 for use in a display device, including a sound guide 10, a limiting component 20, and a pressing component 30. The sound guide 10 is disposed on the back cover 1 of the display device, and a sealing surface 110 is provided on the side of the sound guide 10 away from the back cover 1. The sealing surface 110 is used to seal with the speaker 6. The limiting component 20 is disposed on the back cover 1 and arranged around the sound guide 10. The limiting component 20 abuts against multiple sides of the speaker 6 to restrict the movement of the speaker 6 in a plane parallel to the back cover 1. The pressing component 30 is disposed on the back cover 1 and elastically presses the speaker 6 to press the speaker 6 against the sealing surface 110. The speaker 6, the sound guide 10, and the back cover 1 together form a sound guide cavity 40.

[0025] As can be seen from the above, by arranging the limiting component 20 around the sound guide frame 10 and abutting against multiple sides of the speaker 6, a limiting mechanism is formed in a plane parallel to the rear cover 1 to prevent the speaker 6 from shifting in the plane. The pressing component 30 applies an elastic pressing force to the speaker 6, pressing the speaker 6 against the sealing surface 110 of the sound guide frame 10. Combined with the speaker 6, the sound guide frame 10, and the rear cover 1, which together form the sound guide cavity 40, the sealing failure problem caused by human experience deviation in existing hot-melt assembly is effectively avoided, preventing sound wave leakage to ensure sound stability and achieving saturated sound transmission. Simultaneously, it also avoids the problem of sealing failure caused by human experience deviation in existing hot-melt assembly when tightening screws. Uneven stress distribution prevents the speaker 6 housing from twisting and the diaphragm 9 from becoming unbalanced, fundamentally solving the problem of speaker 6 deformation and sound quality damage caused by existing screw fixing. Moreover, during assembly, the limiting component 20 can quickly position and clamp the component 30 for elastic fixation, eliminating the need for point-by-point heating and curing with hot melt or point-by-point screw operation, thus improving assembly efficiency. The elastic clamping force applied by the clamping component 30 also has fault tolerance, which can avoid the irreversible damage to the speaker 6 and the back cover 1 caused by hot melt, improving the yield rate and saving costs. In addition, there is no need for hot melt operation with a soldering iron, avoiding the health hazards of hot glue odor to operators.

[0026] It should be noted that, as Figure 11 , Figure 12 As shown, the speaker 6 includes a cabinet 8 and a diaphragm 9 disposed at one end of the cabinet 8. The diaphragm 9 is the core component for the speaker 6 to produce sound. The diaphragm 9 faces the sound guide frame 10, so that the sound can act directly into the sound guide cavity 40, avoiding the sound waves from diffusing to other locations and causing energy loss. Furthermore, the sealing surface 110, the limiting component 20, and the pressing component 30 all cooperate with the cabinet 8.

[0027] It should also be noted that, such as Figure 3 The outline shape of the sound guide 10 is matched with the outer outline of the speaker 6, that is, the outer outline of the sound guide 10 is the same as or similar to the outer outline of the speaker 6; thus ensuring that the sealing surface 110 on the sound guide 10 can completely and evenly fit against the edge of the diaphragm 9 of the speaker 6, while allowing the limiting component 20 to be arranged more accurately on the side of the speaker 6, achieving more stable and reliable limiting; in addition, it also saves space.

[0028] It should also be noted that, such as Figure 1 , Figure 3 As shown, the length direction is parallel to the X direction, the width direction is parallel to the Y direction, and the height direction is parallel to the Z direction; in addition, the plane parallel to the back cover 1 is a plane perpendicular to the width direction.

[0029] like Figure 3 , Figure 5As shown, in some embodiments, the limiting component 20 includes a first limiting part 210, a second limiting part 220, and a third limiting part 230; the first limiting part 210 is disposed on both sides of the sound guide 10 in the length direction and is used to transition with the two sides of the speaker 6 in the length direction; the second limiting part 220 is disposed on one side of the sound guide 10 in the height direction and is used to gap fit with one side of the speaker 6 in the height direction; the third limiting part 230 is disposed on the other side of the sound guide 10 in the height direction and is used to transition with the other side of the speaker 6 in the height direction, and to determine the reference position of the speaker 6 in the height direction.

[0030] The first limiting parts 210 are distributed on both sides of the sound guide 10 along its length, and transitionally engage with the two sides of the speaker 6 along its length, thus limiting the displacement of the speaker 6 in the length direction. The third limiting part 230 abuts against the side of the speaker 6 on one side of the sound guide 10 in the height direction, clearly defining the reference position of the speaker 6 in the height direction. At the same time, the second limiting part 220 is in clearance fit with the side of the speaker 6 on the other side in the height direction, ensuring limiting accuracy while reserving assembly space to avoid assembly difficulties caused by dimensional errors. Thus, the first limiting part 210, the second limiting part 220, and the third limiting part 230 work together to achieve stable positioning of the speaker 6 in the length and height directions. In addition, the clearance fit of the second limiting part 220 and the transition fit of the first limiting part 210 can accommodate minor dimensional errors in the production of the speaker 6, avoiding assembly adaptation problems caused by a single interference fit, improving the compatibility of the limiting component 20 with different batches of speaker 6, and enhancing the practicality of the fixing structure.

[0031] It should be noted that there can be multiple first limiting parts 210, and the multiple first limiting parts 210 are arranged at intervals in the height direction; for example Figure 3 , Figure 5 As shown, the sound guide frame 10 has two first limiting parts 210 on both sides in the length direction, and the two first limiting parts 210 are arranged at intervals in the height direction.

[0032] It should also be noted that there can be multiple second limiting parts 220, and the multiple second limiting parts 220 are arranged at intervals in the length direction; such as Figure 3 , Figure 5 As shown, there are two second limiting parts 220.

[0033] It should also be noted that a transition fit refers to a situation where, after assembly, two components may have a slight gap or a slight interference, thus achieving accurate positioning while facilitating disassembly and assembly; a clearance fit refers to a situation where, after assembly, two components have a slight gap. Understandably, the third limiting part 230, serving as a positioning reference, requires higher machining precision.

[0034] like Figure 5As shown, in some embodiments, both the first limiting part 210 and the second limiting part 220 include a limiting member 2101 and a main limiting surface 2102 and a guide surface 2103 disposed on the limiting member 2101; the limiting member 2101 is connected to the outer wall of the sound guide frame 10; the main limiting surface 2102 faces towards the sound guide frame 10 and is used to abut against the side of the speaker 6; the guide surface 2103 is connected to the main limiting surface 2102 and is inclined in the width direction away from the sound guide frame 10 to guide the speaker 6 to be installed.

[0035] By providing a guide surface 2103 inclined away from the sound guide frame 10 in the limiting member 2101, a guiding channel can be formed during the assembly of the speaker 6, so that after the bottom of the speaker 6 contacts the guide surface 2103, it can naturally slide along the inclined surface to the inside of the limiting member 2101, reducing the assembly difficulty and improving efficiency; while the main limiting surface 2102 facing the sound guide frame 10 can form symmetrical abutment on both sides of the length direction of the speaker 6 for the first limiting part 210, avoiding the speaker 6 from shifting, and using surface contact to disperse the abutment force to prevent the speaker 6 from deforming; for the second limiting part 220, the limiting boundary can be clearly defined to prevent the speaker 6 from excessively shaking in the height direction. In addition, the limiting member 2101 is directly connected to the outer wall of the sound guide frame 10. This not only allows the sound guide frame 10 to provide stable support for the limiting member 2101, preventing the limiting member 2101 from deforming or breaking due to the pressure of the speaker 6, thus improving durability, but also ensures the positional accuracy of the main limiting surface 2102 and the guide surface 2103, preventing limiting deviations and ensuring the consistency of the speaker 6 assembly position.

[0036] It should be noted that the dimension of the limiting member 2101 in the width direction is larger than that of the sound guide frame 10 in the width direction, that is, the limiting member 2101 protrudes from the sound guide frame 10, thereby ensuring that the main limiting surface 2102 of the limiting member 2101 can abut against the speaker 6.

[0037] It should also be noted that a reinforcing rib is provided on one side of the limiting member 2101, and the reinforcing rib is connected to the rear cover 1, thereby improving the strength and reliability of the limiting member 2101.

[0038] It should also be noted that the guide surface 2103 is inclined away from the sound guide frame 10, that is, the guide surface 2103 has an inclination angle with the width direction, and the guide surface 2103 includes an inner guide end and an outer guide end in the width direction. The inner guide end is connected to the main limiting surface 2102, and the distance between the outer guide end and the sound guide frame 10 in the length direction is greater than the distance between the inner guide end and the sound guide frame 10 in the length direction.

[0039] like Figure 3 , Figure 5 As shown, in some embodiments, the clamping assembly 30 includes a first clamping member 310 disposed on both sides of the sound guide 10 in the length direction and used to apply an elastic clamping force to the stepped portion 7 of the speaker 6.

[0040] The first clamping member 310 is distributed on both sides of the sound guide frame 10 along the length direction, and applies an elastic clamping force to the stepped part 7 of the speaker 6 to form a balanced force, avoiding the speaker 6 from tilting due to force applied in one direction, so that the speaker 6 is subjected to uniform force as a whole, and ensuring that the speaker 6 is tightly attached to the sealing surface 110 of the sound guide frame 10 to ensure sound stability; at the same time, the first limiting member 2101 is arranged along the length direction of the sound guide frame 10, and can be adapted to the positioning of the first limiting part 210 in the length direction. After the limiting component 20 is positioned, no adjustment is required.

[0041] It should be noted that the box body 8 has stepped portions 7 on both sides along its length, or stepped portions 7 at its corners, with the stepped portions 7 located in the middle of the box body 8; for example, as Figure 3 As shown, steps 7 are provided on all four corners of the box body 8.

[0042] It should also be noted that multiple first pressing members 310 can be respectively provided on both sides of the sound guide frame 10 in the length direction. The first pressing members 310 are arranged at intervals along the height direction, thereby further ensuring that the speaker 6 presses the sealing surface 110 of the sound guide frame 10.

[0043] like Figure 5 , Figure 7 As shown, in some embodiments, the first clamping member 310 includes a support column 3101, a first cantilever 3102, and an operating member 3105; one end of the support column 3101 is connected to the rear cover 1; the first cantilever 3102 is disposed at the end of the support column 3101 away from the rear cover 1, the first cantilever 3102 includes a bent portion 3103 and a clamping ramp 3104, the bent portion 3103 is inclined toward the sound guide frame 10 in the width direction, and the clamping ramp 3104 is disposed at the free end of the bent portion 3103 to clamp the stepped portion 7 of the speaker 6; the operating member 3105 is disposed on the side of the bent portion 3103 away from the sound guide frame 10, and is used to apply external force to cause the first cantilever 3102 to undergo elastic deformation, so as to release the clamping ramp 3104 from the speaker 6.

[0044] The support column 3101 is connected to the rear cover 1 at one end to provide stable support. The bent part 3103 of the first cantilever 3102 faces the sound guide frame 10, which allows the pressing slope 3104 at the end of the first cantilever 3102 to fit against the step part 7 of the speaker 6 and continuously provide pre-tightening pressure, ensuring that the speaker 6 fits tightly against the sealing surface 110 of the sound guide frame 10, preventing the speaker 6 from shifting due to vibration during use, and providing a reliable guarantee for the sealing of the sound guide cavity 40 and the stability of the sound effect. By using the bent portion 3103 inclined towards the sound guide frame 10 as the guide surface, when the speaker 6 is assembled, the guide surface contacts the speaker 6 and generates a lateral force, driving the first clamping member 310 to open outward, so that it can be easily fastened without additional tools. After assembly, the clamping inclined surface 3104 accurately fits the step portion 7 of the speaker 6. By setting the operating member 3105 on the side of the bent portion 3103 away from the sound guide frame 10, the operator can easily drive the first cantilever 3102 to elastically deform by directly applying external force to the operating member 3105 without special tools, and quickly release the clamping state. This avoids the problems of cumbersome disassembly and assembly and easy damage to parts in the existing fixing method, and improves assembly efficiency and the success rate of rework of defective products. By pressing the inclined surface 3104, a vertical pressure perpendicular to the sealing surface is formed, ensuring that the speaker fits tightly against the sealing surface 110 of the sound guide frame 10. Simultaneously, a lateral limiting force is generated, restricting the horizontal displacement of the speaker 6, achieving a synchronized "return and press" effect. Furthermore, the inclined bending part 3103 makes the return to its original position smoother. In addition, the elastic deformation of the first pressing member 310 allows the pressing force to have adaptive adjustment capabilities, accommodating minor dimensional errors. It also buffers the vibration transmission during speaker 6 operation, reduces fatigue wear on the pressing assembly 30 itself, and extends the service life of the speaker 6 and the fixing structure.

[0045] It should be noted that a reinforcing rib is provided on one side of the support column 3101. The reinforcing rib is connected to the rear cover 1, thereby improving the strength and reliability of the first clamping component 310, solving the problem of the first cantilever 3102 easily "nodding" during assembly, ensuring that the bent part 3103 and the clamping inclined surface 3104 can maintain the preset posture, ensuring the guiding accuracy and stable transmission of pre-tightening pressure, and avoiding clamping failure.

[0046] It should also be noted that the first cantilever 3102 also includes a horizontal part, one end of which is connected to the support column 3101 and the other end is connected to the bending part 3103. The bending part 3103 is inclined toward the sound guide frame 10, that is, the bending part 3103 has an inclination angle with the width direction. The bending part 3103 includes an inner bending end and an outer bending end in the width direction. The outer bending end is connected to the horizontal part. The distance between the outer bending end and the sound guide frame 10 in the length direction is greater than the distance between the inner bending end and the sound guide frame 10 in the length direction.

[0047] like Figure 3 , Figure 5As shown, in some embodiments, the clamping assembly 30 further includes a second clamping member 320, which is arranged at a distance from the first clamping member 310 in the height direction and is used to apply an elastic clamping force to the end of the speaker 6 away from the sound guide frame 10.

[0048] By arranging the second clamping member 320 and the first clamping member 310 at intervals in the height direction, the speaker 6 is subjected to uniform force, ensuring that the speaker 6 fits tightly against the sealing surface 110 of the sound guide frame 10, thereby ensuring sound stability and reducing sound wave leakage. At the same time, the interval arrangement of the first clamping member 310 and the second clamping member 320 can distribute the clamping force, avoiding excessive force on a single clamping point that could cause local wear or damage to the speaker 6, thus extending the service life of the speaker 6.

[0049] It should be noted that only the first clamping member 310 can be set to clamp the horn 6, or both the first clamping member 310 and the second clamping member 320 can be set to clamp the horn 6.

[0050] like Figure 5 , Figure 10 As shown, in some embodiments, the second clamping member 320 includes a second cantilever 3201 and a clamping buckle 3203; the second cantilever 3201 is disposed on the rear cover 1, and the second cantilever 3201 is provided with a through hole 3202 extending in the width direction; the clamping buckle 3203 protrudes from the side of the second cantilever 3201 facing the sound guide frame 10 to clamp the end of the speaker 6 away from the sound guide frame 10.

[0051] The second cantilever 3201 is fixed to the rear cover 1. Its protruding clamping buckle 3203 can act on the end of the speaker 6 away from the sound guide frame 10. It works in conjunction with the force applied by the first clamping member 310 to limit the displacement of the speaker 6 and prevent the end of the speaker 6 from lifting due to vibration or external force. At the same time, the clamping buckle 3203 and the speaker 6 adopt an interference fit. The through hole 3202 in the width direction of the second cantilever 3201 provides sufficient elastic deformation space for the second cantilever 3201. This ensures that the interference fit is stable and achieves the pre-compression effect. It also prevents the second cantilever 3201 from being too rigid, making it difficult to install the speaker 6, or from failing to generate effective elastic deformation, causing the clamping buckle 3203 and the speaker 6 to become misaligned. The presence of gaps prevents the formation of reliable pre-pressure, thus ensuring a tight fit between the speaker 6 and the sealing surface 110 of the sound guide 10, thereby guaranteeing the sound stability of the sound guide cavity 40. The use of clamping buckles 3203 for fixing is simple and convenient. During speaker 6 assembly, the clamping buckles 3203 can be directly engaged and fixed through elastic deformation. During disassembly, the clamping buckles 3203 can be released with simple external force without the need for special tools. The second cantilever 3201 and the clamping buckles 3203 have a certain elastic deformation capacity, which can accommodate minor dimensional errors and avoid damage to the speaker 6 caused by rigid clamping. At the same time, the elastic structure can buffer the vibration transmission of the speaker 6 during operation, extending the service life of the speaker 6 and the clamping components.

[0052] It should be noted that the second cantilever 3201 includes a horizontal section and a vertical section. One end of the horizontal section is connected to the rear cover 1, and the vertical section is connected to the end of the horizontal section away from the rear cover 1. The through hole 3202 and the clamping buckle 3203 are both provided on the vertical section, and the clamping buckle 3203 is located above the through hole 3202.

[0053] like Figure 1 , Figures 5-10 As shown, in some embodiments, a fixing cavity 3 is provided on the side of the back cover 1 facing the display surface of the display device, the sound guide 10 is housed in the fixing cavity 3, and the bottom of the sound guide 10 is connected to the bottom of the fixing cavity 3; the bottom of the sound guide 10 is provided with a plurality of sound guide holes 120 that pass through in the height direction, and the back cover 1 is provided with a plurality of sound outlet holes 4 that pass through in the height direction, the plurality of sound outlet holes 4 correspond one-to-one with the plurality of sound guide holes 120, and the sound outlet holes 4 are connected to the corresponding sound guide holes 120 to form a sound guide channel.

[0054] By housing the sound guide bracket 10 within the fixed cavity 3 of the back cover 1 and connecting it to the cavity, the sound guide hole 120 and the sound outlet hole 4 correspond one-to-one to form a sound guide channel. This satisfies the installation requirement of the speaker 6 diaphragm 9 facing the back cover 1, and also allows the sound to be turned 90° within the sound guide cavity 40 before being output through the sound guide channel. When used on a desktop, the sound can be efficiently transmitted through the monitor's tilt angle and secondary reflection from the desktop. When wall-mounted, the sound is prevented from being blocked by the wall, ensuring clear sound effects in various scenarios. Furthermore, compared to existing monitors that use the back of the back cover 1 for sound output, this application only sets the sound outlet hole 4 at the bottom of the back cover 1, which is difficult for users to notice from common angles. This ensures the integrity and simplicity of the back cover 1's appearance and avoids visual flaws caused by empty spaces.

[0055] It should be noted that existing monitors are limited by the length and width of the speaker 6, and the diaphragm 9 of the speaker 6 needs to be installed facing the back cover 1. Existing monitors usually have the sound hole directly opened on the back of the back cover 1, which causes the sound to be output to the back of the monitor. When used on a wall, it is also easy to be blocked by the wall. Therefore, by pressing the speaker 6 against the sealing surface 110 through the pressing component 30 and the limiting component 20 to form the sound guide cavity 40, it is ensured that the surface of the speaker 6 cabinet 8 can be completely sealed with the entire ring of the back cover 1, which provides the basic conditions for sound to be emitted from the bottom of the back cover 1, ensuring that the sound loss is small when it turns 90° and does not affect the sound output effect.

[0056] It should also be noted that, such as Figure 7As shown, the bottom of the back cover 1 is provided with multiple heat dissipation holes 5, which are connected to the fixing cavity 3 to dissipate heat from the electronic components installed in the fixing cavity 3. Understandably, the sound outlet hole 4 can also play a role in heat dissipation. Moreover, the sound outlet hole 4 is located at the bottom of the back cover 1, which is not easily noticed by the user. Therefore, even models without a speaker 6 can use the back cover 1, so that the back cover 1 can be used for both models with and without a speaker 6. There is no need to design the back cover 1 structure separately for different models, thus reducing the mold development cost.

[0057] like Figure 5 As shown, in some embodiments, the third limiting part 230 and the second pressing member 320 are both disposed at the bottom of the fixed cavity 3; the sound guide frame 10, the third limiting part 230 and the second pressing member 320 are arranged sequentially in the width direction, and the top of the third limiting part 230 is provided with a secondary limiting surface 2301, which serves as a positioning reference in the height direction of the speaker 6.

[0058] By using the secondary limiting surface 2301 as a positioning reference in the height direction of the speaker 6, alignment deviations in the height direction are avoided. Simultaneously, it works in conjunction with the first limiting part 210 and the second limiting part 220 to form multiple positioning, improving assembly accuracy and efficiency. The second clamping member 320 applies an elastic clamping force to the end of the speaker 6 away from the sound guide 10, working in conjunction with the secondary limiting surface 2301 at the top of the third limiting part 230. The secondary limiting surface 2301 serves as a positioning reference to lock the speaker 6 in place. The elastic force of the second clamping member 320 ensures that the speaker 6 fits tightly against the secondary limiting surface 2301, preventing gaps or wobbling in the height direction. Furthermore, the arrangement of the second clamping member 320 away from the sound guide 10 avoids spatial interference with the sound guide 10, limiting components 20, etc., fully utilizing the space within the fixed cavity 3 and making the overall structural layout more compact.

[0059] It should also be noted that the assembly process for speaker 6 includes: Pre-positioning: Place the back cover 1 horizontally, and slide the horn 6 at a certain tilt angle (e.g., 4°) along the direction from the second clamping member 320 to the first clamping member 310 until the horn 6 is in contact with the second limiting part 220; then rotate the horn 6 body counterclockwise so that the lower edge of the horn 6 contacts the secondary limiting surface 2301 of the third limiting part 230; continue to rotate the horn 6 with the secondary limiting surface 2301 as the center until the horn 6 initially fits against the first limiting part 210, thus completing the pre-positioning.

[0060] Adaptive Guiding of Clamping Components: During the sliding process of the horn 6, its stepped portion 7 precisely aligns with the bent portions 3103 of the two first clamping components 310. The bent portions 3103 serve as guide surfaces, and the pressure direction of the first clamping components 310 is perpendicular to the guide surfaces. According to the parallelogram decomposition principle of theoretical mechanics, this pressure can be decomposed into a lateral thrust parallel to the length direction and a vertical thrust parallel to the width direction, with the lateral thrust being significantly greater than the vertical thrust. Since the width of the support column 3101 is much greater than the length of the first cantilever 3102, the torque generated by the lateral thrust is greater than the torque generated by the vertical thrust, causing the first clamping components 310 to undergo elastic deformation, providing a smooth downward sliding space for the horn 6 and achieving adaptive guiding assembly.

[0061] Final positioning and sealing: After assembly, the speaker 6 is firmly pressed onto the cavity sealing surface 110 of the sound guide frame 10 through two interference pressure points arranged at intervals in the height direction by the first clamping member 310 and the second clamping member 320, ensuring that the front and rear cavities of the speaker 6 are completely isolated, laying a sealed foundation for high-quality sound output.

[0062] Disassembly procedure for speaker 6: Move the operating part 3105 to drive the first cantilever 3102 to deform elastically and release its clamping force on the step part 7 of speaker 6; then pull the speaker 6 housing 8 or the speaker 6 lead wire (small speaker 6 can be disassembled through the lead wire) to easily remove speaker 6 from the assembly position and complete the disassembly.

[0063] This application also provides a display device, including the speaker fixing structure 2 provided in the foregoing embodiments of this application.

[0064] It should be noted that the display device includes one or more speaker fixing structures 2, and each speaker fixing structure 2 fixes one speaker 6; for example Figure 1 As shown, the display device includes two speaker fixing structures 2, which are arranged at intervals along the length direction.
