[0031] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a multifunctional Bluetooth speaker, including: a housing 10, inside which is provided a PCB motherboard 20, a battery component 30 and a speaker component 40, a light guide component 50 connected to the upper end of the housing 10, a rotating component 60 connected to the light guide component 50, a top cover 70 provided above the light guide component 50, and the top cover 70 being tractively connected to the rotating component 60, the top cover 70 also being provided with a wireless transmitting component 80, and the battery component 30, the wireless transmitting component 80 and the speaker component 40 being electrically connected to the PCB motherboard 20.

[0032] Specifically, the PCB motherboard 20 is installed in a designated area within the housing 10 using a suitable fixing method (such as screw fixing, clip fixing, etc.), ensuring its stability and easy connection with other components. Next, the battery component 30 is installed on the battery bracket 170, and then the battery bracket 170 is fixed to the housing 10. Electrical connections are then established between the battery component 30 and the PCB motherboard 20, typically using wire soldering or plug-in connections. The speaker component 40 is installed on the housing 10 at the corresponding sound-emitting position and is also electrically connected to the PCB motherboard 20 to ensure that audio signals can be transmitted normally to the speaker component 40 and produce sound. The light guide component 50 is installed at the upper end of the housing 10, and can be fixed using clips, adhesive, etc., ensuring that the light guide component 50 is tightly connected to the housing 10 and accurately positioned. The rotating assembly 60 is installed between the light guide 50 and the top cover 70. The rotating assembly 60 typically includes components such as a rotating shaft and bearings. By passing the rotating shaft through corresponding holes on the light guide 50 and the top cover 70, and securing it with fasteners (such as nuts), a transmission connection is established between the top cover 70 and the light guide 50, allowing the top cover 70 to open, close, and have its angle adjusted via the rotating assembly 60. A suitable mounting position is designed on the top cover 70, and the wireless transmitter assembly 80 is installed inside the top cover 70 using adhesive, screws, or other methods, and electrically connected to the PCB motherboard 20 to ensure the wireless charging function functions correctly.

[0033] In addition, the PCB motherboard 20 integrates a Bluetooth module and LED beads. Users can turn on the Bluetooth speaker and search for and connect to its Bluetooth module using a mobile phone or other Bluetooth device. After successful connection, the mobile phone or other device can transmit audio signals to the Bluetooth speaker's PCB motherboard 20. The PCB motherboard 20 processes the audio signals and then transmits them to the speaker unit 40 for playback, enabling music playback. When users need to charge their phones, they magnetically attach the phone to the wireless transmitter component 80 on the top cover 70. At this time, the battery unit 30 powers the wireless transmitter component 80, which generates an electromagnetic field. The wireless charging receiver coil built into the phone senses the electromagnetic field and converts electromagnetic energy into electrical energy to charge the phone's battery. Users can adjust the opening and closing state and angle of the top cover 70 by rotating the component 60 to place the phone in the optimal charging and placement position. When the Bluetooth speaker plays music, the LED beads integrated on the PCB motherboard 20 begin to illuminate. The light emitted by the LED beads is conducted and diffused through the light guide component 50, ensuring the light is evenly distributed across the entire surface of the light guide component 50, creating a soft ambient light. The color, brightness, and other parameters of the ambient lighting can be dynamically adjusted according to factors such as the rhythm and volume of the music, or preset modes can be selected to add a romantic atmosphere and mood.

[0034] In other words, by integrating the battery component 30 and the wireless transmitter component 80 into the housing 10 and the top cover 70, and with the battery component 30, the wireless transmitter component 80, and the speaker component 40 all electrically connected to the PCB motherboard 20, the charging and audio functions are organically combined. Users no longer need to carry additional chargers and charging cables; they can simply magnetically attach their phones to the wireless transmitter component 80 on the top cover 70 to charge them. This integrated design greatly enhances ease of use. Whether at home, in the office, or traveling, users can use a Bluetooth speaker to charge their mobile phones and other electronic devices anytime, anywhere, meeting their need to replenish power anytime, anywhere. In addition, the top cover 70 is connected to the light guide component 50 via the rotating component 60, allowing the top cover 70 to open and close freely and its angle to be adjusted, providing users with a more flexible and personalized charging experience. In actual use, users can freely adjust the opening and closing state and angle of the top cover 70 according to their own needs and the surrounding environment. In addition, the Bluetooth speaker integrates audio playback, wireless charging and ambient lighting functions into one device, achieving the effect of "one device for multiple uses". Users no longer need to purchase additional wireless chargers and ambient lighting devices, reducing usage costs and saving desktop or portable space.

[0035] In one embodiment, the rotating assembly 60 includes a rotating member 61, a rotating shaft 62, and a rotating shaft seat 63. The rotating shaft seat 63 is connected to the light guide member 50. One end of the rotating member 61 is rotatably connected to the rotating shaft seat 63 through the rotating shaft 62, and the other end is connected to the top cover 70.

[0036] Specifically, a suitable installation position is pre-designed on the light guide 50, taking into account the installation stability of the rotating component 60 and its impact on the opening and closing angle of the top cover 70. The rotating shaft seat 63 is securely connected to the light guide 50 using adhesive, screws, or other methods. For example, at the edge of the light guide 50, two small screws are passed through the mounting holes on the rotating shaft seat 63 and screwed into the corresponding threaded holes on the light guide 50 to ensure that the rotating shaft seat 63 will not loosen during use. The rotating shaft 62 is inserted into the shaft hole on the rotating shaft seat 63. There should be a suitable clearance between the shaft hole and the rotating shaft 62 to ensure smooth rotation of the rotating shaft 62 while avoiding excessive clearance that could cause wobbling during rotation. An interference fit or the addition of grease can be used to optimize the fit between the rotating shaft 62 and the shaft hole. One end of the rotating component 61 is designed with a hole that matches the rotating shaft 62. This end is fitted onto the rotating shaft 62, allowing the rotating component 61 to rotate around the rotating shaft 62. The rotating component 61 can be prevented from falling off the rotating shaft 62 by setting a retaining ring or using a nut for limiting. The other end of the rotating component 61 is connected to the top cover 70 by means of adhesive, snap-fit ​​connection or screw fixation, so as to ensure that the top cover 70 can open and close and adjust the angle as the rotating component 61 rotates.

[0037] Since the rotating component 61 and the pivot seat 63 are rotatably connected via the rotating shaft 62, the user only needs to gently push the top cover 70 with their hand, and the top cover 70 will drive the rotating component 61 to rotate around the rotating shaft 62, thus allowing the top cover 70 to open and close freely. The rotational engagement between the rotating shaft 62 and the pivot seat 63 should have a certain degree of damping, so that after the user releases their hand, the top cover 70 can remain in its current position and will not close or open on its own. The user can adjust the top cover 70 to different angles as needed. For example, when the user wants to magnetically attach the phone to the top cover 70 at a more tilted angle for charging, they only need to continue pushing the top cover 70 to rotate the rotating component 61 to the corresponding angle. The structural design of the rotating component 60 can ensure that the top cover 70 stays stably at that angle, making it convenient for the user to operate the phone. In addition, the light guide component 50 is designed to be hollow, and the size of its internal space should be reasonably planned according to actual needs. While ensuring that the installation and normal operation of the rotating component 60 are not affected, the size of the hollow part should be maximized as much as possible to provide sufficient storage space for use as a storage bucket. Users can place small items, such as headphone cables, keys, and USB flash drives, inside the hollow of the light guide 50.

[0038] In one embodiment, a pluggable wireless charging assembly 90 for a watch is also provided on one side of the housing 10.

[0039] Specifically, the watch wireless charging component 90 typically consists of a charging coil, a circuit board, and a housing. The charging coil is the core component, used to generate an electromagnetic field for wireless charging of the watch; the circuit board is responsible for controlling the charging process, including communicating with the Bluetooth speaker's PCB motherboard 20 and adjusting the charging power; the housing protects the internal components and fixes the charging coil in place, and is generally made of insulating and durable plastic. A plug-in interface is designed at one end of the watch wireless charging component 90. The interface can be a common universal interface such as USB-C or Micro USB, or a custom interface specifically designed for the Bluetooth speaker. A matching interface is provided on one side of the housing 10, which should be electrically connected to the PCB motherboard 20 inside the Bluetooth speaker. A wire can be used to connect the housing 10 interface to the corresponding interface on the PCB motherboard 20; the wire should be of sufficient length and flexibility to accommodate the plugging and unplugging of the watch wireless charging component 90.

[0040] In other words, the addition of the watch wireless charging component 90 allows the Bluetooth speaker to not only charge devices like mobile phones but also provide wireless charging services for smartwatches, further expanding the product's charging capabilities. Users no longer need to carry a separate charger for their watches; simply placing the watch on the wireless charging component 90 is sufficient for charging, improving convenience. This design demonstrates the product's compatibility with various electronic devices, adapting to the needs of different users. Whether users are using smartwatches for health monitoring and activity tracking, or those who own both a mobile phone and a watch, this Bluetooth speaker provides a one-stop solution for charging, enhancing the product's practicality and market competitiveness. Furthermore, the watch wireless charging component 90 is detachable, significantly improving space utilization. When not in use, users can unplug it, reducing the space occupied by the Bluetooth speaker and making it easier to carry and store. For example, when traveling or on business trips, users can decide whether to bring the watch wireless charging component 90 based on their actual needs, making the Bluetooth speaker's use more flexible.

[0041] In one embodiment, the housing 10 is further provided with a support frame 100 at the position of the watch wireless charging component 90, and one end of the watch wireless charging component 90 passes through the support frame 100 and is electrically connected to the PCB motherboard 20.

[0042] Specifically, the support frame 100 is typically made of a material with a certain strength and rigidity, such as plastic or metal. Its shape is designed to accommodate the passage of the watch wireless charging component 90 and provide stable support. For example, the support frame 100 can be designed as a frame structure with circular or square holes, the size and shape of which match the dimensions of the watch wireless charging component 90, ensuring the component can pass through smoothly without excessive wobbling. Simultaneously, the edges of the support frame 100 can be reinforced with ribs to enhance its structural strength and prevent deformation during long-term use. The support frame 100 is securely mounted to the housing 10 at the corresponding location on the housing 10 where the watch wireless charging component 90 is installed, using methods such as screws, snap-fit ​​connections, or adhesive.

[0043] In other words, the support frame 100 provides stable support for the wireless charging component 90 of the watch, preventing the component from shaking or shifting due to its own weight or external forces during use. Especially when the watch is placed on the wireless charging component for charging, the support frame 100 can ensure that the component remains stable, ensuring a smooth charging process and improving the reliability and safety of the product.

[0044] In one embodiment, the watch wireless charging assembly 90 includes a watch charging upper shell 91, a plug 92, a watch charging coil 93, a watch charging PCB board 94, and a watch charging lower shell 95. The watch charging upper shell 91 and the watch charging lower shell 95 are connected to form a mounting cavity. The plug 92, the watch charging coil 93, and the watch charging PCB board 94 are disposed in the mounting cavity, and the plug 92 extends out of the mounting cavity and is electrically connected to the PCB board 20. The plug 92 and the watch charging coil 93 are electrically connected to the watch charging PCB board 94.

[0045] Specifically, the upper casing 91 and lower casing 95 of the watch charger are typically made of insulating and durable plastic using injection molding. The plug 92 is designed according to the connection requirements with the Bluetooth speaker PCB motherboard 20, and commonly uses universal interfaces such as USB-C, MicroUSB, and Type-C, but custom interfaces are also possible. The watch charging coil 93 is made of enameled wire, and the number of turns, wire diameter, and other parameters are determined according to the power and frequency requirements of the wireless charging. The watch charging PCB board 94 is fabricated according to the circuit design, integrating charging control chips, capacitors, resistors, and other electronic components.

[0046] In other words, the watch charging coil 93 generates an alternating magnetic field after being powered on. When the smartwatch is placed above the watch wireless charging assembly 90, the receiving coil inside the watch senses the alternating magnetic field and generates an induced current, thus achieving wireless charging. The charging control chip on the watch charging PCB board 94 precisely controls the charging process, including adjusting the charging power and monitoring the charging status, ensuring that the watch can be charged safely and efficiently. The stable electrical connection between the plug 92, the watch charging PCB board 94, and the PCB motherboard 20 ensures reliable transmission of the charging signal. In addition, the mounting cavity formed by the connection of the upper and lower casings 91 and 95 provides good protection for the plug 92, the watch charging coil 93, and the watch charging PCB board 94. It can prevent damage to the internal components from external factors such as dust, moisture, and impacts, extending the service life of the watch wireless charging assembly 90.

[0047] In one embodiment, the housing 10 is further provided with a button bracket 110 on the side away from the watch wireless charging assembly 90. The button bracket 110 is connected to a button group 120, and the button group 120 is electrically connected to the PCB motherboard 20.

[0048] Specifically, the button bracket 110 is typically made of plastic and manufactured using injection molding. Its shape is designed according to the internal space of the housing 10 and the layout of the button assembly 120. A suitable installation position is reserved on the side of the housing 10 away from the watch's wireless charging component 90. The button bracket 110 is then installed on the housing 10 using screws, snap-fit ​​connections, or adhesive. For example, multiple screw holes are designed on the button bracket 110, and corresponding threaded holes are drilled on the housing 10, allowing for a tight connection using screws; alternatively, a snap-fit ​​structure can be designed to allow the button bracket 110 to quickly and securely snap onto the housing 10. The button assembly 120 includes multiple buttons, such as play / pause, previous / next track, and white noise time setting buttons. These buttons can be mechanical or touch buttons, selected according to design requirements. Each button in the button assembly 120 is connected to a corresponding contact on the PCB motherboard 20 using a thin wire. A pre-prepared white noise music file is then burned into the memory chip on the PCB motherboard 20 using a programmer or a dedicated burning device. A control program is written in the microcontroller of the PCB motherboard 20 to implement the switching and time setting functions of white noise music by the button group 120 and the Bluetooth module. For example, when the user presses the play / pause button, the program controls the playback or pause of the white noise music; when the user presses the previous / next track button, the program switches to different white noise music; when the user presses the white noise time setting button and operates it in conjunction with other buttons, the program sets the playback time of the white noise music.

[0049] In other words, the button group 120 provides users with an intuitive and convenient way to operate the speaker. Users can quickly switch white noise music and set playback time simply by pressing the corresponding buttons, without needing external devices such as mobile phones. The operation is simple and easy to understand, making it especially suitable for nighttime use or when it's inconvenient to use a mobile phone. The addition of the Bluetooth module further expands the operation methods, allowing users to remotely control the Bluetooth speaker within a certain range using Bluetooth devices such as mobile phones. For example, when lying in bed, users can easily switch music or adjust the white noise time using their mobile phones without getting up to operate the buttons, improving convenience and comfort. Furthermore, the white noise music burned into the PCB motherboard 20 has a soothing and relaxing effect, helping users block out external noise and create a quiet and comfortable sleep environment, helping users fall asleep faster and improving sleep quality.

[0050] In one embodiment, a light-shielding film 180 is also provided between the button bracket 110 and the button assembly 120.

[0051] Specifically, the use of the light-shielding film 180 makes the area between the button bracket 110 and the button assembly 120 look more aesthetically pleasing and neat. It conceals the internal structure and wiring of the button bracket 110 and button assembly 120, preventing these internal components from being exposed and affecting the overall appearance of the product. In addition, the light-shielding film 180 also provides some dust and moisture protection. It prevents dust, moisture, and other impurities from entering the area between the button bracket 110 and the button assembly 120, reducing the corrosion and damage of these impurities to the internal components and extending the lifespan of the button assembly 120 and other related components.

[0052] In one embodiment, a sleeve 160 is further provided on the outer periphery of the housing 10.

[0053] Specifically, the button assembly 120 passes through the sleeve 160 and the light-shielding film 180 and connects to the button bracket 110. The sleeve 160 fits around the outer periphery of the housing 10, providing support and reinforcement. Especially around the button assembly 120, frequent button operation may exert external forces on the housing 10. The sleeve 160 can disperse these forces, reducing deformation or damage to the housing 10 and improving its overall strength and stability. Furthermore, the design of the sleeve 160 can coordinate with the overall appearance of the housing 10, making the product look more unified and aesthetically pleasing. The color, material, and surface treatment of the sleeve 160 can be matched with the housing 10 to create different visual effects and meet the aesthetic needs of different users. For example, a metal sleeve 160 can give the product a high-end, fashionable feel, enhancing its perceived quality.

[0054] In one embodiment, the bottom of the housing 10 is further provided with a bottom cover 130, the bottom cover 130 is provided with a charging PCB board 140, and the charging PCB board 140 is electrically connected to the PCB motherboard 20.

[0055] Specifically, the shape of the bottom cover 130 is designed according to the shape and size of the housing 10 to fit snugly against the bottom of the housing 10. The charging PCB board 140 is placed in the pre-drilled mounting area of ​​the bottom cover 130, and screws are used to securely fix the charging PCB board 140 to the bottom cover 130 by passing screws through the fixing holes on the charging PCB board 140 and the corresponding holes on the bottom cover 130. Depending on the charging requirements, a suitable charging interface is selected, such as a USB-C interface or a Micro-USB interface, and the charging interface is soldered onto the charging PCB board 140, ensuring a firm connection between the interface and the PCB board and good electrical performance.

[0056] In other words, by using common charging interfaces, such as USB-C, users can use common mobile phone chargers, power banks, and other devices to charge the Bluetooth speaker without having to carry a dedicated charger, thus improving charging convenience.

[0057] In one embodiment, the bottom of the bottom cover 130 is further provided with a foot pad 150.

[0058] Specifically, rubber feet (150) are a common choice, such as silicone rubber and natural rubber. Silicone rubber has good heat resistance, cold resistance, electrical insulation, and chemical stability, maintaining stable performance under different temperature conditions and exhibiting good resistance to various chemicals. Natural rubber has good elasticity and high strength, but its aging resistance is slightly inferior to silicone rubber. The texture or material properties of the feet (150) increase the friction between the foot and the surface where it is placed. For example, rubber feet (150) typically have anti-slip textures, effectively preventing the Bluetooth speaker from sliding on smooth tabletops and ensuring the product's stability.

[0059] In one embodiment, the wireless transmitting assembly 80 includes a wireless transmitting coil 81 and a magnetic coil 82. The wireless transmitting coil 81 is located in the central region of the top cover 70, and the magnetic coil 82 is located on the outer periphery of the wireless transmitting coil 81.

[0060] Specifically, the top cover 70 also features a decorative piece 190 above the magnetic coil 82. This can be achieved by applying adhesive to the back of the decorative piece 190, then accurately placing it on the top cover 70 above the magnetic coil 82 and pressing firmly to ensure a tight fit. Furthermore, the cooperation between the wireless transmitting coil 81 and the magnetic coil 82 allows the phone to be magnetically held and wirelessly charged. In other words, the ingenious combination of the wireless transmitting coil 81 and the magnetic coil 82 utilizes magnetic attraction to securely hold the phone while achieving efficient wireless charging. This design not only improves charging convenience but also avoids the inconveniences caused by tangled cables or incompatible interfaces in traditional charging methods. Additionally, the introduction of the magnetic coil 82 enhances the connection stability between the phone and the Bluetooth speaker and reduces phone movement during charging through magnetic force, thus improving charging stability and safety. Finally, the decorative piece 190 adds a unique aesthetic appeal to the product. Decorative pieces 190 in different materials, colors, and patterns can meet the aesthetic needs of different users, making products more personalized and fashionable. For example, metal decorative pieces 190 can give products a high-end and luxurious feel; while plastic decorative pieces 190 with colorful patterns can create a lively and fun atmosphere.

[0061] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
