Description

Technical Field

[0001] This utility model relates to the technical field of multi-purpose speakers, and in particular to a multi-purpose smart Bluetooth speaker with an adsorption structure. Background Technology

[0002] With the continuous development of wireless communication technology, Bluetooth speakers have become an important product in modern audio equipment due to their portability and convenient wireless connectivity. Traditional Bluetooth speakers have a built-in Bluetooth chip, which pairs with devices such as smartphones and tablets via Bluetooth to achieve wireless audio playback, greatly facilitating the user experience. Most Bluetooth speakers are designed to be small and lightweight, suitable for placement on a desktop or carried in a bag, meeting the needs of daily use or some outdoor scenarios.

[0003] However, existing Bluetooth speakers have significant limitations in terms of usage:

[0004] Limited portability: Mainstream products are primarily designed for desktop placement. While they can be carried in a bag, they lack convenient hanging structures, failing to meet users' needs for hanging them on their person during outdoor activities and sports (such as hanging them on backpack shoulder straps or bicycle handlebars).

[0005] Poor adaptability to special scenarios: It cannot be stably placed on inclined planes or vertical walls (such as bathroom tile walls, glass curtain walls, car dashboards, etc.), making it difficult for users to use the speaker flexibly in scenarios such as showering, bathing, and kitchen operations, thus limiting the expansion of usage scenarios.

[0006] Installation and fixing methods are limited: Traditional suction cup structures have problems such as insufficient suction force, cumbersome installation and disassembly or the need for tools, and the stability is prone to decline due to the aging of the suction cup when used repeatedly, making it impossible to balance convenience and load-bearing reliability.

[0007] Insufficient integration of functions and protection: Some speakers do not integrate waterproof design or sound pickup function, making them difficult to adapt to the use needs of humid environments (such as bathrooms), and the sound diffusion effect is limited and the sound field coverage is limited.

[0008] Therefore, the market urgently needs a Bluetooth speaker with innovative structure, flexible installation, multiple usage methods, and convenient operation to meet users' needs for multi-functional and multi-scenario audio playback devices in different environments and usage habits. Utility Model Content

[0009] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0010] This utility model provides a multi-purpose smart Bluetooth speaker with an adsorption structure, including a speaker body with an internal cavity and an adsorption device detachably connected to the speaker body. An energy storage component, a circuit component, and a speaker are electrically connected to each other inside the cavity. The energy storage component provides power for the speaker's operation, and the circuit component controls and manages the energy storage component and the speaker. The speaker emits sound under the control of the circuit component. A flat base is installed at the bottom of the speaker body, allowing the speaker body to be placed on an external platform for use. The adsorption device can be adsorbed onto an external plane to keep the speaker body in an adsorbed state for use.

[0011] Furthermore, it also includes a flexible strap fixed to the speaker body, which is used to keep the speaker body in a suspended state for use.

[0012] Furthermore: one end of the adsorption device is provided with a T-shaped protrusion, and the other end is provided with a suction cup for adsorption onto the external plane; the flat base is provided with an opening groove, so that the T-shaped protrusion can be inserted into the opening groove to form a mechanical interlock.

[0013] Furthermore, the adsorption device also includes a pressure plate, a screw cap, and a face cover. A stud is fixedly connected to the central area of ​​the back of the suction cup. The pressure plate is fitted onto the stud through an opening and has a bowl-shaped groove on the side facing the suction cup, so that the edge of the bowl-shaped groove abuts against the back of the suction cup. The face cover and the pressure plate are fixedly connected to each other and form a gap, so that the screw cap can rotate and connect to the gap between the face cover and the pressure plate. A drive ring is provided in the central area of ​​the screw cap. The drive ring is fitted onto the stud and forms a threaded connection.

[0014] Furthermore, the edge of the bowl-shaped groove of the pressure plate is provided with a plurality of first toothed strips evenly distributed along the circumference of the pressure plate, and the part of the suction cup corresponding to the edge of the bowl-shaped groove is also provided with a plurality of second toothed strips evenly distributed along the circumference of the suction cup. When the pressure plate abuts against the suction cup, the plurality of first toothed strips and the plurality of second toothed strips interlock and embed with each other to form a mutually limiting state.

[0015] Furthermore, a limiting barrier is provided on the circumferential direction of the back of the suction cup away from the second toothed rack. When the pressure plate abuts against the suction cup, the ends of multiple first toothed racks block the limiting barrier.

[0016] Furthermore: A support rod is provided between the cover and the pressure plate. One end of the support rod is fixed to the cover, and the other end is fixed to the pressure plate by bolts, so that the cover and the pressure plate are fixedly connected by the support rod.

[0017] Furthermore: the edge of the screw cap is provided with an annular wall along the circumference, and the inner side of the annular wall is provided with a plurality of evenly arranged third racks corresponding to one end of the pressure plate. The pressure plate is provided with a rack lever, a lever spring and a lever groove on one side corresponding to the third rack. The rack lever is slidably connected to the lever groove, and the two ends of the lever spring abut against the lever groove and the rack lever respectively. Its elastic force drives the rack lever to abut against the third rack.

[0018] Furthermore, the speaker body also includes a bowl-shaped container and an annular cover plate that are fixed together to form the speaker cabinet. The speaker is mounted on the annular cover plate, and the energy storage component and circuit component are mounted inside the bowl-shaped container. A diffusion cone is also mounted on the top of the annular cover plate, and a button component is provided on the top of the diffusion cone for controlling the speaker.

[0019] Furthermore, it also includes an outer shell and an acoustic mesh. The outer shell is fastened to the side wall of the bowl-shaped container and has sound transmission holes for sound transmission. The acoustic mesh is attached to the outer shell.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] I. Flexible use in multiple scenarios

[0022] 1. Flat placement: The flat base with silicone anti-slip feet ensures stability when placed on flat surfaces such as desktops and tabletops, while the shock absorption properties of the silicone material optimize the sound quality on hard platforms and reduce resonance noise.

[0023] 2. Suspension Use: The flexible straps are made of flexible and tensile-resistant materials such as nylon fabric. They can be bent and shaped, and can be easily attached to backpacks, clothes hangers, tent frames and other objects through the "U" shaped structure or hook design, meeting the suspension needs of outdoor camping, sports and fitness and freeing up your hands.

[0024] 3. Adsorption and fixation: Quick-assembly and disassembly mechanical interlocking structure: The T-shaped opening groove of the flat base cooperates with the T-shaped boss of the adsorption device, and locking or separation can be achieved by sliding. No bolts or tools are required. It is convenient to install and disassemble and has reliable load-bearing capacity. It is suitable for smooth surfaces such as vertical walls and glass.

[0025] The suction cup structure with enhanced negative pressure: the screw cap drives the stud to move axially, and the pressure plate and the suction cup are cross-limited by the racks (the first rack and the second rack mesh) and the limit fence design, so that the suction cup produces uniform radial tensile deformation, which improves the negative pressure strength and the adsorption stability is better than that of traditional suction cups. It can withstand the weight of the speaker and adapt to humid environments (such as bathroom walls).

[0026] II. Structural Design Optimization

[0027] 1. Damping and locking of the adsorption device: The third rack on the edge of the cap works in conjunction with the rack and pinion of the pressure plate and the actuating spring. When rotating, the tooth surface squeezes to provide a damping feel. After it is in place, it automatically engages in the tooth groove to lock, preventing accidental loosening and enhancing operational reliability.

[0028] 2. Acoustic and protective performance: Dual-sided speakers with top diffuser cone effectively enhance low-frequency response and diffuse sound waves, achieving wide sound field coverage; waterproof button, waterproof microphone and charging port cover design improve the speaker's protection level in humid environments (reaching IPX4 waterproof), expanding its applicability to bathroom, kitchen and other scenarios.

[0029] 3. Functional integration and appearance: Built-in rechargeable lithium battery, Bluetooth chip, microphone and other components, supporting music playback, call function and local storage (memory card); the shell is combined with acoustic mesh (waterproof nylon material), which not only beautifies the appearance and protects the speaker, but also minimizes sound obstruction, taking into account both functionality and aesthetics.

[0030] III. User Experience and Market Competitiveness

[0031] 1. Single device adaptable to multiple scenarios: Through three modes of flat placement, hanging, and adsorption, it meets the needs of users in all scenarios from home and office to outdoor and humid environments, reducing the cost of purchasing multiple devices.

[0032] 2. Ease of use: Tool-free disassembly and assembly, screw cap damping lock, waterproof buttons and other designs reduce the threshold of use and improve the comfort of operation.

[0033] 3. Product Reliability: The mechanical interlocking and negative pressure adsorption fixing structure, silicone anti-slip and shock absorption, and waterproof protection enhance the product's durability and stability, thus optimizing its market competitiveness.

[0034] In summary, this utility model, through its integrated design of a flat base, flexible strap, and detachable adsorption device, significantly expands the application scenarios of Bluetooth speakers, solves the limitations and inconveniences of existing technologies, and substantially enhances the product's versatility and user experience, thus possessing high practical value and promising prospects for promotion.

Detailed Implementation

[0049] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] Please see Figures 1 to 10 In this embodiment of the present invention, a multi-purpose smart Bluetooth speaker with an adsorption structure includes a speaker body 10 with an internal cavity and an adsorption device 40 detachably connected to the speaker body 10. An energy storage component 21, a circuit component 22, and a speaker 23 are electrically connected to each other within the cavity. The energy storage component 21 provides power for the speaker's operation, and the circuit component 22 controls and manages the energy storage component 21 and the speaker 23. The speaker 23 emits sound under the control of the circuit component 22. A flat base 30 is installed at the bottom of the speaker body 10, allowing the speaker body 10 to be placed on an external platform for use. The adsorption device 40 can be adsorbed onto an external plane to keep the speaker body 10 in an adsorbed state for use.

[0051] Specifically, a Bluetooth speaker refers to an audio device with a built-in Bluetooth chip that uses Bluetooth connectivity instead of traditional wired connections. It connects to Bluetooth playback devices such as mobile phones, tablets, or laptops for convenient and quick use. Bluetooth speakers are primarily designed for portability, featuring a small and lightweight design. Their Bluetooth connectivity technology has gained increasing acceptance among consumers due to its ease of use. Common Bluetooth speakers on the market are typically placed on desktops or other platforms. While they can be carried in a bag, they are not convenient for hanging or using, especially on inclined surfaces or vertical walls. For example, placing a Bluetooth speaker in the bathroom or while taking a bath presents challenges.

[0052] This invention provides a multi-purpose Bluetooth speaker by incorporating a flat base 30 at the bottom, making it easy to place on a desktop or other surface. It also features a flexible strap 11 for easy attachment to hooks, straps, or other objects for hanging, and an adsorption device 40 for easy attachment to vertical or inclined surfaces such as tile or glass walls. This expands the speaker's usability, meets users' needs for multi-scenario use of a single speaker, enhances the user experience, and improves the product's market competitiveness.

[0053] Secondly, the bottom surface of the flat base 30 is also provided with anti-slip pads 31, which can prevent the speaker body 10 from sliding when placed on a desktop or other platform. At the same time, the anti-slip pads 31 can be made of materials such as silicone with a certain degree of elasticity, so that they have anti-slip performance and shock absorption performance, thus optimizing the speaker's performance on hard platforms.

[0054] like Figure 1 , Figure 2 and Figure 5 As shown, preferably, it also includes a flexible strap 11 fixed to the speaker body 10, the flexible strap 11 being used to keep the speaker body 10 in a suspended state for use.

[0055] Specifically, to make the speaker's suspension more flexible, the preferred flexible strap 11 is made of a flexible and tensile-resistant material (such as nylon cloth or composite fiber tape), which has the characteristic of being bendable and shape-adjustable. For easy hanging, it can be double-layered to form an "U"-shaped structure and fixed to the annular cover 15 of the speaker body 10 with bolts, thus securely hanging and moving the entire speaker. In addition, hooks can be installed on the flexible strap 11, allowing for convenient hanging on external straps, belts, or other objects, enhancing the user's convenience for carrying the speaker.

[0056] Secondly, the flexible strap 11 is fixed to the top of the annular cover plate 15 by bolts, and its free end can be bent and hung on an external object.

[0057] like Figure 3 , Figure 5 and Figure 6 As shown, preferably, one end of the adsorption device 40 is provided with a T-shaped protrusion 41 and the other end is provided with a suction cup 70 for adsorption on the outer plane; the flat base 30 is provided with an opening groove 32, so that the T-shaped protrusion 41 is inserted into the opening groove 32 to form a mechanical interlock.

[0058] Specifically, the bottom surface of the flat base 30 is provided with a T-shaped opening groove 32, the width of which is smaller than the width of the inside of the tank. After the T-shaped boss 41 of the adsorption device 40 is inserted into the opening 33 provided on one side of the opening groove 32, it slides along the direction of the opening groove 32 to the end of the tank and achieves mechanical interlocking through the stepped structure of the boss and the tank.

[0059] Secondly, when disassembly is required, the speaker body 10 is reversed, causing the flat base 30 to move a certain distance along the opening direction of the slot 32, thus releasing the T-shaped boss 41. The T-shaped boss 41 can then be removed through the opening 33 to achieve separation. This design allows for bolt-free assembly and disassembly, quick installation and removal, reusability, and good load-bearing capacity.

[0060] In use, first, the adsorption device 40 is adsorbed onto a flat surface such as an external wall using the suction cup 70. Then, the opening 33 on one side of the opening groove 32 on the bottom surface of the flat base 30 is aligned with the T-shaped protrusion 41 of the adsorption device 40, so that the T-shaped protrusion 41 is inserted into the opening groove 32 and slides a certain distance towards the bottom of the opening groove 32 to lock it, thereby making the speaker body 10 detachably and fixedly installed on the adsorption device 40.

[0061] like Figures 4 to 10 As shown, preferably, the adsorption device 40 also includes a pressure plate 60, a screw cap 50, and a face cover 42. A stud 71 is fixedly connected to the central area of ​​the back side of the suction cup 70. The pressure plate 60 is fitted onto the stud 71 through an opening, and a bowl-shaped groove 61 is provided on the side facing the suction cup 70, so that the edge of the bowl-shaped groove 61 abuts against the back side of the suction cup 70. The face cover 42 is fixedly connected to the pressure plate 60, and a gap is formed between them, so that the screw cap 50 is rotatably connected to the gap between the face cover 42 and the pressure plate 60. A drive ring 51 is provided in the central area of ​​the screw cap 50, and the drive ring 51 is fitted onto the stud 71 to form a threaded connection.

[0062] Specifically, the front side of the suction cup 70, i.e. the adsorption surface, is used to adsorb external planes, and its back side is provided with a stud 71 with external threads. In order to fit onto the stud 71 and prevent the pressure plate 60 from rotating around the stud 71, the opening of the pressure plate 60 can be set as a racetrack-shaped hole, and the cross section of the stud 71 can also be set as a racetrack-shaped cross section, so that the pressure plate 60 fits onto the stud 71 and can move along the axial direction of the stud 71, but cannot rotate circumferentially around the stud 71.

[0063] Secondly, the drive ring 51 is fitted onto the stud 71, and forms a threaded connection with the stud 71 through the internal thread on the inner wall of the drive ring 51. When the cap 50 rotates, the drive ring 51 drives the stud 71 to move along its axial direction, thereby locking or releasing the suction cup 70. For example, when the cap 50 is rotated clockwise, the drive ring 51 drives the stud 71 to move closer to the cover 42 for locking; when rotated counterclockwise, the stud 71 is driven to move away from the cover 42 for releasing the suction cup 70. The suction cup 70 is made of silicone material with a Shore hardness of 40-50, and produces a radial tensile deformation of 5-8% when the stud 71 is axially displaced by 3mm.

[0064] In use, first rotate the cap 50, causing the drive ring 51 to move the stud 71 away from the cover 42, reducing the volume of the cavity formed by the suction cup 70's adsorption surface. This is equivalent to expelling the air from the cavity, allowing the suction cup 70 to adhere to an external surface, such as a tiled or glass wall. Then, rotate the cap 50 in the opposite direction, causing the drive ring 51 to move the stud 71 closer to the cover 42. This causes the stud 71 to extend the suction cup 70 into the bowl-shaped groove 61, creating a deformation that increases the volume of the cavity formed by the suction cup 70's adsorption surface. However, since the adsorption surface of the suction cup 70 is in contact with the external surface, air cannot enter the cavity, creating a negative pressure inside. This atmospheric pressure then firmly adheres the adsorption device 40 to the external surface.

[0065] Additionally, when it is necessary to remove the suction device 40, rotate the cap 50 again, causing the drive ring 51 to move the stud 71 away from the cover 42, reducing the cavity volume formed by the suction surface of the suction cup 70, which is equivalent to reducing the negative pressure. Then, the edge of the suction cup 70 can be pried up by the pull tab 72 protruding from the edge of the suction cup 70, breaking its vacuum seal, thereby easily removing the suction cup 70.

[0066] like Figure 7 , Figure 9 and Figure 10 As shown, preferably, the edge of the bowl-shaped groove 61 of the pressure plate 60 is provided with a plurality of first toothed racks 62 evenly distributed along the circumference of the pressure plate 60, and the suction cup 70 is also provided with a plurality of second toothed racks 73 evenly distributed along the circumference of the suction cup 70 at the part corresponding to the edge of the bowl-shaped groove 61. When the pressure plate 60 abuts against the suction cup 70, the plurality of first toothed racks 62 and the plurality of second toothed racks 73 intersect and embed with each other to form a mutually limiting state.

[0067] Specifically, the cross-sections of the first rack 62 and the second rack 73 are trapezoidal, and the spacing between the racks is 1.5 times the tooth width, ensuring a grid-like limiting effect when they interlock. Multiple first racks 62 and multiple second racks 73 interlock in the gaps between the racks, thus creating a mutually limiting state, making the force exerted by the pressure cap on the suction cup 70 more dispersed and uniform. The first racks 62 and the second racks 73 interlock circumferentially, forming a grid-like limiting structure, allowing the radial force applied by the pressure plate 60 to be transmitted to the entire circumference of the suction cup 70 through the meshing between the racks, avoiding localized stress concentration. The first rack 62 is disposed on the bottom surface of the bowl-shaped groove 61, and the second rack 73 is disposed on the top surface of the suction cup 70. When the pressure plate 60 and the suction cup 70 come into contact with each other, the multiple first racks 62 and second racks 73 distributed in the circumference interlock to form a meshing structure. This allows the force of the pressure plate 60 to be distributed relatively evenly on the entire ring of racks, and prevents the suction cup 70 from failing due to excessive local stress caused by the force being concentrated in a certain place.

[0068] Secondly, the axial direction of each first rack 62 is distributed along the radial direction of the pressure plate 60. Similarly, the axial direction of each second rack 73 is also distributed along the radial direction of the suction cup 70. The intervals between the multiple first racks 62 are the same, and the intervals between the multiple second racks 73 are also the same. Moreover, the intervals between the two are equal, so that the first racks 62 and the second racks 73 are intersected and embedded in each other's intervals, forming a mutually limiting state.

[0069] like Figure 7 and Figure 9 As shown, preferably, a limiting fence 74 is also provided on the back of the suction cup 70 in the circumferential direction away from the second toothed rack 73. When the pressure plate 60 abuts against the suction cup 70, the ends of the plurality of first toothed racks 62 block the limiting fence 74.

[0070] Specifically, when the cap 50 is rotated in the opposite direction, causing the drive ring 51 to move the stud 71 toward the faceplate 42, and the stud 71 to extend the suction cup 70 into the bowl-shaped groove 61, producing a certain deformation and increasing the volume of the cavity formed by the suction surface of the suction cup 70, in order to enhance the deformation of the suction cup 70, it is preferable to set a limiting fence 74 at the edge of the suction cup 70 away from the second rack 73, and use the end of the first rack 62 to block the limiting rack, keeping it at the edge position, thereby causing the suction cup 70 to produce greater deformation and enhancing its negative pressure strength.

[0071] Secondly, the limiting fence 74 can be directly connected to the end of the second rack 73. By utilizing the interlocking fit between the first rack 62 and the second rack 73, the first rack 62 can better block the limiting fence 74.

[0072] like Figures 8 to 10 As shown, preferably, a support rod 43 is provided between the cover 42 and the pressure plate 60. One end of the support rod 43 is fixed to the cover 42, and the other end is fixed to the pressure plate 60 by bolts, so that the cover 42 and the pressure plate 60 are fixedly connected by the support rod 43.

[0073] Specifically, to create a gap between the cover 42 and the pressure plate 60, a support rod 43 can be provided on the bottom surface of the cover 42, and the pressure plate 60 can be fixed to the support rod 43 by bolts. The cap 50 is provided with a clearance hole 52 corresponding to the position of the support rod 43, so that when the cap 50 rotates, the support rod 43 can move to the position of the clearance hole 52. At the same time, after the cap 50 rotates to a preset angle, the two side walls of the clearance hole 52 also block the support rod 43, limiting the rotation position of the cap 50, thereby forming two states of locking or releasing the suction cup 70.

[0074] Secondly, a support spring 44 is provided between the cover 42 and the screw cap 50. The support spring 44 is sleeved on the drive ring 51 of the screw cap 50 and abuts against the cover 42 and the screw cap 50 respectively, thereby applying a specific damping effect to the rotational movement of the screw cap 50, preventing the screw cap 50 from being too loose and enhancing the user's feel when turning the screw cap 50. The T-shaped boss 41 is fixed to the top surface of the cover 42 by bolts, so that the cover 42 is detachably fixed to the flat base 30 through the T-shaped boss 41.

[0075] like Figures 8 to 10 As shown, preferably, the edge of the screw cap 50 is provided with an annular wall 53 along the circumferential direction. The inner side of the annular wall 53 is provided with a plurality of evenly arranged third racks 54 corresponding to one end of the pressure plate 60. The pressure plate 60 is provided with a rack lever 64, a lever spring 65 and a lever groove 63 on one side corresponding to the third racks 54. The rack lever 64 is slidably connected to the lever groove 63. The two ends of the lever spring 65 abut against the lever groove 63 and the rack lever 64 respectively. Its elastic force drives the rack lever 64 to abut against the third racks 54.

[0076] Specifically, in order to apply specific damping to the rotation of the cap 50, it is preferable to provide a toggle groove 63 at the top edge of the pressure plate 60, and to provide a rack and pinion block 64 in the toggle groove 63. Using the elastic force of the toggle spring 65, the rack and pinion block 64 is driven to engage with the gap between the two third racks 54, forming a near-meshing state. When the cap 50 is rotated, the third racks 54 rotate synchronously, so that their inclined teeth form pressure on the rack and pinion block 64 in the direction of the central axis of the pressure plate 60, and compress the toggle spring 65, so that the rack and pinion block 64 slides a certain distance in the direction of the central axis of the pressure plate 60, thereby disengaging from the meshing state and allowing the cap 50 to rotate normally.

[0077] Once the cap 50 is rotated to its position, the rack and pinion block 64, under the elastic force of the actuating spring 65, re-engages into the tooth groove of the third rack 54, thereby locking the rotation angle of the cap 50 and locking the adsorption state of the adsorption device 40. This structure also improves the user's rotation feel.

[0078] like Figures 1 to 5 As shown, preferably, the speaker body 10 also includes a bowl-shaped container 12 and an annular cover plate 15 fixedly connected to each other to form the speaker cabinet. The speaker 23 is installed in the annular cover plate 15, and the energy storage component 21 and the circuit component 22 are installed in the bowl-shaped container 12. A diffusion cone 16 is also installed on the top of the annular cover plate 15, and a button component 20 is provided on the top of the diffusion cone 16 for controlling the speaker.

[0079] Specifically, in order to form the speaker enclosure, it is preferable to set up a bowl-shaped container 12 and an annular cover plate 15 that are fixed together to form a cavity structure, so that the speaker 23 is mounted on the annular cover plate 15 through the pressure strip 17. In order to enhance the sound effect of the speaker, the speaker 23 can be a dual-suspension speaker 23 in the prior art, thereby enhancing the low frequency response. The dual-suspension speaker 23 can more effectively drive the air and produce a stronger low frequency effect, making the sound fuller and more powerful.

[0080] The energy storage component 21 is manufactured using existing rechargeable lithium batteries, and the circuit component 22 is equipped with existing chips or circuit modules such as battery management chip, Bluetooth connection chip, sound driver chip, intelligent management chip, and button management module to control and manage the speaker's functions.

[0081] Secondly, to diffuse the sound waves emitted by the speaker 23, it is preferable to provide a diffusion cone 16 on the top of the speaker 23. The diffusion cone 16 evenly diffuses the sound in all directions, thus breaking up the sound waves and avoiding excessive directivity, thereby achieving a wider sound field coverage. For speaker control, it is preferable to install a button assembly 20 on the diffusion cone 16. The button assembly 20 is electrically connected to the circuit assembly 22 to control and manage the speaker. Waterproof buttons, as used in the prior art, are employed to improve the speaker's waterproof performance. Preferably, the top of the diffusion cone 16 has a waterproof button assembly 20 embedded, including a power switch, volume up / down buttons, play / pause button, and Bluetooth pairing button. Each button is electrically connected to the button management module in the circuit assembly 22 via wires.

[0082] Furthermore, to enhance stability, the flexible strap 11 is bolted to a pre-set mounting post on the top of the annular cover plate 15, and its free end can be bent to form a suspension ring. For ease of use, a charging interface, memory card, and microphone (preferred in the art) are preferably installed on the side wall of the bowl-shaped container 12. The charging interface charges the energy storage component 21, the memory card stores music files for direct playback via the sound driver chip, and the microphone expands the speaker's call functionality. To optimize the cabinet's sound parameters, a sealing groove 13 and a sealing cover plate 14 are preferably provided on the inner side of the bowl-shaped container 12 to seal the corresponding mounting holes. The microphone is preferably a waterproof microphone (preferred in the art), and the mounting holes are sealed with adhesive. A waterproof cap can also be provided on the outer side of the bowl-shaped container 12 to waterproof and seal the charging interface and memory card area.

[0083] like Figure 1 , Figure 2 and Figure 5As shown, preferably, it also includes an outer shell 80 and an acoustic mesh 82. The outer shell 80 is fastened to the side wall of the bowl-shaped container 12, and a sound transmission hole 81 is provided on the outer shell 80 for sound transmission; the acoustic mesh 82 is attached to the outer shell 80.

[0084] Specifically, to enhance the overall aesthetics of the Bluetooth speaker, a shell 80 is preferably designed to be snapped onto the speaker body 10. This shell effectively covers the sound transmission gap between the annular cover 15 and the sound-amplifying cone, creating a beautiful arc shape on the outer side of the entire enclosure and improving its appearance. Furthermore, to allow for light and sound transmission, corresponding sound transmission holes 81 are provided on the shell 80 at positions corresponding to the annular cover 15 and the sound-amplifying cone, enabling proper sound diffusion.

[0085] Secondly, in order to protect the speaker 23 and maintain a uniform appearance, existing acoustic mesh fabric 82, such as waterproof nylon cloth or other breathable and waterproof nylon woven materials, can be used. It can be attached to the outer wall of the housing 80 using an adhesive connection method, thereby minimizing sound obstruction and distortion, while protecting the speaker 23 unit and optimizing the overall visual appearance of the speaker.

[0086] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
