[0026] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0027] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0028] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0029] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; direct connections or indirect connections via an intermediate medium; and internal communication between two components or the interaction between two components. For example, a direct connection refers to two parts or components being connected together without an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0030] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0031] In the description of this application, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" than another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" when referring to the first feature as being "above," "to the left," "to the right," "to the front," or "to the rear" of the second feature include the first feature being directly above, to the left, to the right, to the front, or to the rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0032] The technical solution of this application will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] This application provides a speaker device, such as Figures 1-3 As shown, the speaker device includes a housing 5, a support bracket 1, a battery assembly 2, a circuit board assembly 4, and a speaker assembly 3. The battery assembly 2, the circuit board assembly 4, and the speaker assembly 3 are all mounted on the support bracket 1 to ensure stability. The housing 5 covers the outside of the support bracket 1 and is used to protect the internal structure. The battery assembly 2 and the speaker assembly 3 are both electrically connected to the circuit board assembly 4. The battery assembly 2 can power the speaker device and control the speaker to play sound through the circuit board assembly 4.

[0034] To reduce the footprint of the speaker device during use, a flat design is needed, meaning the length and width of the speaker device need to be reduced. However, since portable speaker devices require a battery pack 2 for power and also need to house circuit boards and speakers, the speaker device needs to be designed to be quite tall to allow sufficient internal space. This results in the speaker device being unstable during use, making it prone to tipping over and posing a safety risk.

[0035] like Figures 2-6As shown, in order to solve the above problems, the speaker device provided in this embodiment includes a support bracket 1 including a first bracket 11 and a second bracket 12. The first bracket 11 has a first mounting space 111 inside. The first bracket 11 and the second bracket 12 are detachably connected to form a second mounting space 121 between the first bracket 11 and the second bracket 12. The battery assembly 2 is disposed in the first mounting space 111. At least a portion of the circuit board assembly 4 is disposed in the second mounting space 121. The speaker assembly 3 is disposed on the outside of the support bracket 1.

[0036] In this speaker device, the support bracket 1 is the main support structure inside the speaker device, and the support bracket 1 is divided into a first bracket 11 and a second bracket 12 that can be detachably connected, so as to facilitate assembly and disassembly and improve maintenance efficiency. The battery assembly 2 is set in the first mounting space 111 of the first bracket 11, so that the battery assembly 2 utilizes the thickness space of the first bracket 11 itself. The circuit board assembly 4 is partially set in the second mounting space 121 between the first bracket 11 and the second bracket 12, thereby utilizing the thickness space between the first bracket 11 and the second bracket 12. By utilizing the internal space of the support bracket 1 to place the battery assembly 2 and the circuit board assembly 4, the space utilization rate is improved.

[0037] The speaker device uses a flat design to reduce its radial dimension on the support bracket 1, while also avoiding the problem of excessive height caused by the stacking of components on the support bracket 1 in the axial direction. This allows the speaker device to remain stable during use, reduces the risk of tipping over, and improves safety.

[0038] It is worth noting that the speaker assembly 3 is located at the second end 17 of the support bracket 1 along its own axial direction, which can further reduce the radial dimension of the speaker device on the support bracket 1. The first bracket 11 and the second bracket 12 can be detachably connected by clips, screws or other detachable structures.

[0039] It is worth noting that, for ease of description, this embodiment uses a vertically configured speaker device as an example. That is, the axis of the support bracket 1 is vertical, the second end 17 of the support bracket 1 is the top end, and the first end 16 is the bottom end.

[0040] like Figures 3-5 As shown, in this embodiment, the circuit board assembly 4 includes a first circuit board 41 and a second circuit board 42. The first circuit board 41 is disposed at the first end 16 of the support bracket 1 along its own axial direction and is electrically connected to the battery assembly 2. The second circuit board 42 is disposed in the second mounting space 121, and the second circuit board 42 and the first circuit board 41 are inserted and engaged along the axial direction of the support bracket 1.

[0041] The first mounting space 111 has an mounting port at the bottom of the support bracket 1. The operator can install the battery assembly 2 into the first mounting space 111 through the mounting port. The first circuit board 41 is set at the bottom of the support bracket 1, which can shorten the distance between the first circuit board 41 and the battery assembly 2 as much as possible, thereby shortening the length of the connecting line between the battery assembly 2 and the first circuit board 41. The second circuit board 42 is installed in the second mounting space 121. There is enough space to expand the area of ​​the second circuit board 42, which facilitates circuit design.

[0042] It is worth noting that, to improve the safety of the speaker device, the speaker device also includes a sealing component 14. The first mounting space 111 has a mounting opening formed at the first end 16 of the support bracket 1 along its own axial direction. The first circuit board 41 covers the mounting opening, and the sealing component 14 is disposed on the side of the first circuit board 41 facing away from the mounting opening. The sealing component 14 is used to protect the first circuit board 41. In other words, the battery assembly 2 is installed in a sealed cavity, thereby isolating it from outside air. Even if the battery assembly 2 is damaged by unforeseen factors, it can reduce the amount of air entering the first mounting space 111, thereby reducing the risk of spontaneous combustion of the battery assembly 2.

[0043] Preferably, the fire resistance rating of the first installation space 111 can reach V0 level, which provides high safety.

[0044] It is worth noting that since the first circuit board 41 is located at the bottom of the support bracket 1, if the first circuit board 41 blocks the mounting opening, it will deform due to changes in air pressure within the first mounting space 111, making it prone to damage. Therefore, an allowance opening 411 can be provided on the first circuit board 41, and a sealing member 14 can be provided on the side of the first circuit board 41 facing away from the mounting opening, covering the allowance opening 411. The sealing member 14 is fixedly connected to the first circuit board 41.

[0045] like Figure 3 and Figure 4 As shown, a first sealing ring 15 is provided between the sealing member 14 and the first circuit board 41. The first sealing ring 15 surrounds the clearance opening 411 to seal the gap between the sealing member 14 and the first circuit board 41. A second sealing ring is provided between the first circuit board 41 and the first bracket 11. The second sealing ring surrounds the mounting opening to seal the gap between the first circuit board 41 and the first bracket 11. Through the cooperation of the first sealing ring 15 and the second sealing ring, the entry of external air, liquid, or dust into the first mounting space 111 through the clearance opening 411 and the mounting opening can be reduced, thereby improving the protective performance of the first mounting space 111.

[0046] In other words, after covering the battery assembly 2 with a layer of foam, it can be inserted into the first installation space 111, and then the first circuit board 41 connected to the connecting wire of the battery assembly 2 can be placed at the bottom of the support bracket 1 and fixed with screws. Then, the sealing member 14 can be fixed on the first circuit board 41, and the first circuit board 41 can be fixed and sealed with the first bracket 11 by locking to ensure the sealing performance.

[0047] After fixing the first circuit board 41 onto the support bracket 1, the second circuit board 42 can be placed on the side wall of the support bracket 1, and the second circuit board 42 can be moved downward along the axial direction of the support bracket 1 so that the second circuit board 42 and the first circuit board 41 can be inserted and connected.

[0048] In this embodiment, the sidewall of the first bracket 11 is provided with a guide structure, and the second circuit board 42 has a guide hole 421 extending along the axial direction of the support bracket 1. The guide structure passes through the guide hole 421 and slides relative to the guide hole 421 along the axial direction of the support bracket 1. The guide structure and the guide hole 421 cooperate to guide and cooperate, ensuring that the second circuit board 42 will not shift when the operator moves the second circuit board 42 toward the first circuit board 41, so that the second circuit board 42 can be accurately inserted into the first circuit board 41, thereby improving installation efficiency.

[0049] like Figures 4-6 As shown, specifically, the guide structure includes at least one first post 112, which corresponds one-to-one with the guide hole 421 and passes through the guide hole 421. The first post 112 slides within the guide hole 421, and the guide hole 421 can guide the first post 112 by sliding abutting against the first post 112 through its inner wall.

[0050] like Figure 5 As shown, specifically, the guide hole 421 is an oblong hole, so the inner wall of the guide hole 421 includes two straight sections 4211 and two arc-shaped sections. The two straight sections 4211 are spaced apart, and the distance between the two straight sections 4211 is equal to or slightly greater than the diameter of the first column 112. The long axis of the guide hole 421 is the same as the axial direction of the support bracket 1. When the first column 112 moves between the two straight sections 4211, it can move along the long axis of the guide hole 421, thereby causing the second circuit board 42 to move along the axial direction of the support bracket 1.

[0051] In this embodiment, a first fixing post 115 is provided on the side wall of the first bracket 11, and the second circuit board 42 is supported on the first fixing post 115 and fixedly connected to the first fixing post 115. The first fixing post 115 can support and fix the second circuit board 42, thereby reducing the shaking of the second circuit board 42 relative to the first bracket 11 and improving the installation stability of the second circuit board 42.

[0052] Preferably, the first fixing post 115 is connected to a first upright post 112 via a reinforcing wall 116, and the reinforcing wall 116 is at the same height as the first fixing post 115 to support the second circuit board 42. It is understood that the slender structure of both the first fixing post 115 and the first upright post 112 results in insufficient strength. Connecting the first fixing post 115 and the first upright post 112 via the reinforcing wall 116 improves the overall strength and increases the support area for the second circuit board 42, reducing localized stress on the second circuit board 42, preventing damage to the second circuit board 42, and ensuring the stability of the second circuit board 42.

[0053] In some embodiments, the guide structure further includes at least one pair of second posts 113, which are respectively clamped on opposite sides of the second circuit board 42, and each second post 113 slides against the side wall of the second circuit board 42. The two second posts 113 clamp the second circuit board 42, so that the second circuit board 42 can move along the axial direction of the support bracket 1, thereby achieving the guiding effect on the second circuit board 42.

[0054] In this embodiment, the sidewall of the first bracket 11 is provided with a limiting structure, and the second circuit board 42 has a limiting surface 422. When the second circuit board 42 moves towards the first circuit board 41 along the axial direction of the support bracket 1, the limiting structure can abut against the limiting surface 422 to limit the movement of the second circuit board 42. The limiting structure and the limiting surface 422 cooperate to limit the second circuit board 42 when the first circuit board 41 and the second circuit board 42 are inserted into place, so that the operator knows that the first circuit board 41 and the second circuit board 42 have been inserted into place, and avoids damage to the insertion structure between the first circuit board 41 and the second circuit board 42 due to excessive force by the operator.

[0055] It is worth noting that in some embodiments, the limiting structure can be provided with a limiting post separately, and a limiting groove or other structure can be provided at the corresponding position of the second circuit board 42 to limit the second circuit board 42 and the support bracket 1.

[0056] like Figures 4-6 As shown, in this embodiment, the limiting structure is a first post 112, and the limiting surface 422 is the inner wall of the end of the guide hole 421 away from the first circuit board 41. The first post 112 can slide relative to the guide hole 421. When the second circuit board 42 moves toward the first circuit board 41 until the first post 112 abuts against the limiting surface 422 in the guide hole 421, the first circuit board 41 completes the insertion with the second circuit board 42. That is to say, the first post 112 and the guide hole 421 not only guide the second circuit board 42, but also limit its movement, improving integration and simplifying the complexity of the structure.

[0057] In some embodiments, the limiting structure further includes at least one pair of second posts 113. Limiting grooves 423 are formed on opposite sides of the second circuit board 42. Each second post 113 corresponds to and slides with each limiting groove 423. The limiting surface 422 is the inner wall of the end of the limiting groove 423 away from the first circuit board 41. When the second circuit board 42 moves towards the first circuit board 41 until the second post 113 abuts against the inner wall of the end of the limiting groove 423 away from the first circuit board 41, the first circuit board 41 completes the insertion with the second circuit board 42. In other words, the second post 113 and the limiting groove 423 not only guide the second circuit board 42 but also limit its movement, improving integration and simplifying structural complexity.

[0058] It is understandable that when the speaker device has many functions, the first circuit board 41 and the second circuit board 42 may not be able to implement them, such as... Figure 3 and Figure 4 As shown, in order to increase the number of functions supported by the circuit board assembly 4, the circuit board assembly 4 also includes a third circuit board 43, and the third circuit board 43 is disposed on the side of the second circuit board 42 adjacent to the battery assembly 2 and is electrically connected to the second circuit board 42. The third circuit board 43 and the second circuit board 42 are inserted and mated along the radial direction of the support bracket 1.

[0059] The third circuit board 43 and the second circuit board 42 are stacked radially along the support bracket 1. The third circuit board 43 can be installed on the side of the second circuit board 42 facing the first bracket 11 where there are no tall electrical components, thereby expanding the functionality of the circuit board assembly 4.

[0060] Preferably, the third circuit board 43 and the second circuit board 42 are radially inserted into each other along the support bracket 1, allowing the third circuit board 43 to move with the second circuit board 42. After the second circuit board 42 and the third circuit board 43 are inserted into place, the operator can move the second circuit board 42 towards the first circuit board 41 to achieve insertion between the second circuit board 42 and the first circuit board 41. Furthermore, this insertion method ensures that when the second circuit board 42 is installed in place, the third circuit board 43 is clamped and fixed by the second circuit board 42 and the first bracket 11, preventing them from separating and improving stability.

[0061] In this embodiment, a second fixing post 117 is provided on the side wall of the first bracket 11, and the third circuit board 43 is supported on the second fixing post 117 and fixedly connected to the second fixing post 117. The second fixing post 117 can support and fix the third circuit board 43, thereby reducing the shaking of the third circuit board 43 relative to the first bracket 11 and improving the installation stability of the third circuit board 43.

[0062] In some embodiments, the second circuit board 42 and the first fixing post 115, as well as the third circuit board 43 and the second fixing post 117, can be fixedly connected by screws, rivets, snap-fit ​​structures, or other fixing structures. The specific fixing method can be set according to the installation space and assembly requirements.

[0063] In this embodiment, the sidewall of the first bracket 11 is provided with a flat mounting surface 114 to form a second mounting space 121 with the second bracket 12 for mounting the second circuit board 42 and the third circuit board 43.

[0064] It is worth noting that, in order to optimize the external structure of the speaker device, the support bracket 1 is cylindrical in shape. The side wall of the first bracket 11 is a major arc and the side wall of the second bracket 12 is a minor arc. When the first bracket 11 and the second bracket 12 are assembled together, their side walls form a cylindrical structure. The major arc of the first bracket 11 and the mounting plane 114 can maximize the first mounting space 111, thereby accommodating a larger battery assembly 2 and ensuring the battery life of the speaker device.

[0065] like Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the first end 16 of the support bracket 1 along its own axial direction is provided with a plurality of fixed connecting feet 18, which are fixedly connected to the outer shell 5 to improve the stability of the support bracket 1 within the outer shell 5. Specifically, a fixing ring 51 is provided at the bottom inside the outer shell 5, and a mounting hole is provided on the bottom surface of the fixing ring 51. The mounting component fixes the fixed connecting feet 18 to the fixing ring 51 through the mounting hole. It is worth noting that the mounting hole is located on the bottom surface of the fixing ring 51, which facilitates the operator to disassemble and assemble the mounting component, making assembly and disassembly convenient.

[0066] Preferably, the speaker enclosure 5 has a light-transmitting structure, and more preferably a semi-transparent structure, which allows light to pass through while concealing the internal structure of the enclosure 5. For example... Figures 2-4 As shown, the speaker device also includes a first light-emitting component 7, which includes multiple light strips 71. The multiple light strips 71 are arranged in a circumferential ring around the outer circumferential surface of the support bracket 1. The extension direction of each light strip 71 is parallel to the axial direction of the support bracket 1. All multiple light strips 71 are electrically connected to the circuit board assembly 4.

[0067] The outer casing 5 serves two purposes: firstly, it protects the internal support bracket 1 and other structures mounted on it; secondly, it allows light emitted from the internal first light-emitting component 7 to be transmitted outward, thereby enhancing the aesthetics of the speaker device. Furthermore, multiple light strips 71 spaced along the outer perimeter of the support bracket 1 provide a uniform lighting effect, and different light signals can be selected as needed.

[0068] Preferably, the side wall of the support bracket 1 is provided with a plurality of fixing grooves 13 at intervals along the circumference. Each fixing groove 13 is corresponding to a fixing strip 71, so as to play a role in positioning and fixing the strip 71. This is not only conducive to the operator installing the strip 71 on the support bracket 1, but also ensures the stability of the position of the strip 71.

[0069] It is worth noting that the light strip 71 extends along the axial direction of the support bracket 1. Therefore, in order to shorten the length of the connecting wire, the light strip 71 is electrically connected to the first circuit board 41 disposed at the bottom of the support bracket 1. In some embodiments, the light strip 71 may also be electrically connected to the second circuit board 42 or the third circuit board 43, and the designer may make a suitable choice as needed.

[0070] It is worth noting that because the speaker assembly 3 is located on top of the support bracket 1, the light strip 71 can illuminate a portion of the housing 5, preventing proper lighting signals from being displayed on the top of the housing 5, thus affecting its aesthetics. Figure 2 and Figure 3 As shown, to solve the above problems, the speaker device also includes a second light-emitting component 8. The second light-emitting component 8 includes a light-emitting element 81 and a light guide element 82. Both the light-emitting element 81 and the light guide element 82 are disposed at the second end 17 of the support bracket 1 along its own axial direction. The light guide element 82 extends along the axial direction of the support bracket 1 in a direction away from the support bracket 1 and guides the light emitted by the light-emitting element 81.

[0071] The light guide 82 extends in a direction away from the support bracket 1, and can guide the light emitted by the light-emitting element 81 upward and illuminate the part of the housing 5 located above the support bracket 1. It can illuminate all the side walls of the housing 5 as needed, thus improving the aesthetics.

[0072] Specifically, the light guide 82 is an annular structure extending circumferentially along the support bracket 1, and the speaker assembly 3 is disposed inside the light guide 82. After the light emitted by the light-emitting element 81 enters the light guide 82, it can illuminate the light guide 82 and propagate radially outward along the support bracket 1 through the light guide 82, so as to ensure that the outer casing 5 is illuminated. Furthermore, the speaker assembly 3 is disposed inside the light guide 82, which can also prevent the speaker assembly 3 from blocking the light emitted outward from the light guide 82, thus ensuring the display effect.

[0073] Preferably, the light-emitting element 81 includes an annular fourth circuit board 811 and a plurality of lamp beads 812 spaced apart on the fourth circuit board 811. The bottom end of the annular light guide 82 faces the plurality of lamp beads 812, so that the light emitted by the plurality of lamp beads 812 can directly enter the light guide 82, reducing light leakage and increasing the brightness of the light guide 82.

[0074] like Figure 2 and Figure 3As shown, in this embodiment, since the speaker assembly 3 is located inside the light guide 82, to avoid the light guide 82 affecting the sound propagation of the speaker assembly 3, the light guide 82 includes a plurality of light guide pillars 821 spaced apart circumferentially. The plurality of light guide pillars 821 can achieve the function of guiding light, ensuring that the housing 5 can be illuminated and display the light signals normally, while the gap between adjacent light guide pillars 821 can allow sound waves to pass through, thereby avoiding the light guide 82 from blocking the speaker assembly 3 and ensuring the stable sound effect of the speaker device.

[0075] like Figure 2 and Figure 3 As shown, in this embodiment, the speaker assembly 3 includes a tweeter 31 and a woofer 32. A sound-emitting hole is provided on the top of the housing 5. The tweeter 31 is disposed within the sound-emitting hole and fixedly connected to the housing 5. The woofer 32 is disposed between the tweeter 31 and the support bracket 1. The tweeter 31 (high-frequency unit) and the woofer 32 (low-frequency unit) cooperate to enable the speaker device to cover a wider frequency range, allowing the speaker device to reproduce the full range of realistic sound as much as possible and improving the sound playback effect.

[0076] The speaker assembly 3 generates heat during operation. Since the second circuit board 42 and the third circuit board 43 are located near the woofer 32, the heat generated by the speaker assembly 3 may be transferred to the second circuit board 42 and the third circuit board 43, thus affecting the operation of the circuit board assembly 4. Therefore, a heat insulation plate 33 is also provided inside the speaker enclosure. The heat insulation plate 33 is located on the side of the woofer 32 facing the circuit board assembly 4, and is situated between the woofer 32 and the circuit board assembly 4. This provides heat insulation for the speaker assembly 3 and the circuit board assembly 4. The speaker assembly 3 generates heat when producing sound, and since the second circuit board 42 and the third circuit board 43 are relatively close to the speaker, the heat insulation plate 33 can prevent the heat emitted by the speaker from propagating towards the second circuit board 42 and the third circuit board 43, thereby reducing the impact of the heat generated by the speaker assembly 3 on the operation of the circuit board assembly 4 and improving the operational reliability of the circuit board assembly 4.

[0077] like Figure 1 As shown, in this embodiment, the speaker device also includes a lifting member 6. The lifting member 6 is arranged around the outer shell 5 and fixedly connected to the outer shell 5. The bottom of the lifting member 6 is provided with a support foot 61 so as to stably place the speaker device on a flat surface. The top of the lifting member 6 is spaced apart from the top of the outer shell 5 so as to hold the top of the lifting member 6 by hand to lift the speaker device for easy movement.
