[0043] As Figures 1-4 As shown in the figure, a multifunctional Bluetooth sound box, comprising a hollow structure 1, the hollow structure 1 has a containing cavity, and a ring-shaped channel is formed in the containing cavity;

[0044] The starting end of the ring-shaped channel is provided with a first mounting port 13, the terminal end of the ring-shaped channel is provided with a second mounting port 14, and the middle end of the ring-shaped channel is provided with a third mounting port 15;

[0045] The containing cavity is provided with a power supply and a circuit mainboard 2 connected with each other, and the circuit mainboard is provided with a Bluetooth receiving chip;

[0046] The first mounting port 13 is provided with a loudspeaker assembly 5;

[0047] The second mounting port 14 is fitted with an aromatherapy component 6;

[0048] The third mounting is hinged with a flip cover 7, and the flip cover 7 has a built-in wireless charging module;

[0049] The speaker assembly 5, the aromatherapy assembly 6, and the wireless charging module are all electrically connected to the main circuit board 2.

[0050] like Figures 1-4 As shown, this multi-functional Bluetooth speaker cleverly integrates audio functions, aromatherapy functions, and mobile phone charging and placement functions into one unit. Its working principle is as follows:

[0051] First, users can pair and connect with the speaker's built-in Bluetooth receiver chip using external Bluetooth devices such as mobile phones or tablets. Once successfully connected, the Bluetooth receiver chip receives audio signals from the Bluetooth device and transmits them to the main circuit board 2. The main circuit board 2 processes the audio signals and drives the speaker assembly 5, installed at the first mounting port 13, to produce sound, thus enabling audio playback.

[0052] Next, the aromatherapy component 6 is installed inside the hollow structure 1 through the second mounting port 14. The aromatherapy component 6 releases aroma into the surrounding environment through the annular channel or the specific diffuser port, i.e., the second mounting port 14, to achieve an aromatherapy effect, which helps to relax the mind and body, enhance the atmosphere of the living or working environment, and increase the enjoyment of life.

[0053] Finally, the third mounting port 15 provides a flip cover 7 and a wireless charging module. Users can place their mobile phones on the stand and connect them via the wireless charging module. The wireless charging module connects to the main circuit board 2, which obtains power from the power supply and outputs it to the mobile phone for wireless charging. This built-in phone charging function allows users to charge their phones while using the speaker, avoiding battery anxiety and improving ease of use. The power supply, main circuit board 2, and Bluetooth receiver chip are not shown in the attached diagram.

[0054] In summary, this multi-functional Bluetooth speaker integrates three major functions: audio playback, aromatherapy diffusion, and mobile phone charging and placement, greatly enhancing the product's practicality and convenience and meeting diverse user needs.

[0055] To further explain, the hollow structure 1 includes a front shell 11 and a rear shell 12. A first mounting port 13 is provided at the center of the front shell 11 and the rear shell 12. A second mounting half-hole and a third mounting half-hole are provided on the outer periphery of the front shell 11 and the rear shell 12.

[0056] The front housing 11 and the rear housing 12 are detachably combined to form the hollow structure 1, and the second mounting half hole is combined to form the second mounting port 14, and the third mounting half hole is combined to form the third mounting port 15.

[0057] like Figure 2 As shown, specifically, the design of the front housing 11 and rear housing 12 fully considers the utilization of internal space, allowing each functional component to be compactly installed within a limited space, ensuring functional integrity while saving external dimensions. At the same time, the detachable design of the front housing 11 and rear housing 12 makes the speaker assembly and maintenance more convenient. Users can easily replace or upgrade internal components as needed, such as the aromatherapy component 6 and the speaker component 5.

[0058] To further explain, the front housing 11 and the rear housing 12 are spiral structures, with the first mounting port 13 as the starting end and the second mounting half hole as the ending end.

[0059] like Figure 2 As shown, specifically, the front housing 11 and the rear housing 12 are intertwined and tightly fitted together in a spiral design to form a hollow structure 1. This design ensures the stability of the hollow structure 1 while providing sufficient internal space to accommodate key components such as the power supply, circuit board 2, and Bluetooth receiver chip.

[0060] During assembly, the first mounting port 13 serves as the starting point, providing a positioning reference for the installation of the speaker assembly 5; while the second mounting port 14, formed by merging the second mounting half-hole, provides space for the installation of the aromatherapy assembly 6. The spiral design also allows for the opening of a third mounting half-hole at an appropriate location, which, after merging, forms a third mounting port 15 for installing the flip cover 7 and the wireless charging module.

[0061] More importantly, the spiral design is not only practical but also aesthetically pleasing, which can stimulate users' curiosity and desire to explore, increasing the product's attractiveness and recognizability.

[0062] Further explanation includes an LED light strip 8, which extends spirally from the first mounting port 13 of the spiral structure to the third mounting half-hole.

[0063] like Figures 1-2 As shown, the aforementioned layout allows the LED light strip 8 to fit snugly against the speaker's spiral-shaped outer shell, creating a unique light and shadow effect. Users can adjust the brightness and color of the LED light strip 8 to create different atmospheres, meeting various usage scenarios and needs. Simultaneously, the audio-light synchronization function also provides users with a richer auditory and visual experience.

[0064] To further explain, the outer surface of the hollow structure 1 is provided with a groove, and a time display screen 9 is installed in the groove. The time display screen 9 is electrically connected to the circuit motherboard 2.

[0065] like Figure 3 As shown, firstly, the time display 9 is cleverly placed on the outer surface of the hollow structure 1 of the speaker, typically in a position easily accessible to the user's eye, allowing for easy time checking of the time. Secondly, as an additional feature of the speaker, the time display 9 further enhances the product's added value and market competitiveness. It makes this multi-functional Bluetooth speaker more attractive and differentiated from similar products.

[0066] To further explain, the aromatherapy component 6 includes a breathable cover 61 and an ultrasonic atomizing device 62;

[0067] The breathable cover 61 is installed at the second mounting port 14, and the ultrasonic atomizing device 62 is installed at the rear end of the breathable cover 61. The ultrasonic atomizing device 62 contains a fragrance.

[0068] like Figures 1-2 As shown, specifically, an aromatherapy component 6 is provided in the second mounting port 14, and the aromatherapy component 6 consists of a breathable cover 61, an ultrasonic atomizing device, and an aromatherapy agent installed opposite to each other. The ultrasonic atomizing device is powered by the circuit board 2 and atomizes the aromatherapy agent into tiny particles, so that the aromatherapy is emitted outward 61 through the breathable cover of the second mounting port 14 via ultrasonic vibration.

[0069] To further explain, the speaker assembly 5 includes a connecting ring 51, a speaker structure 52, a pin structure 53, and a buckle 54;

[0070] The connecting ring 51 is fixedly installed on the outer periphery of the first mounting port 13. The horn structure 52 is electrically connected to the circuit board 2. One end of the horn structure 52 is hinged to the connecting ring 51 through the pin structure 53. Another end of the horn structure 52 is snapped to the connecting ring 51 through the buckle 54.

[0071] Specifically, the design and operating principle of speaker assembly 5 mainly revolve around the synergistic effect of its various components. Specifically:

[0072] As the basic fixing part of the speaker assembly 5, the connecting ring 51 is securely installed on the outer periphery of the first mounting port 13. This installation process ensures that the speaker assembly 5 can be stably fixed in the required position, providing a foundation for subsequent assembly and functional realization.

[0073] The speaker structure 52 is the core component for sound generation. It is electrically connected to the main circuit board 2 to receive electrical signals and convert them into sound. Physically, one end of the speaker structure 52 is hinged to the connecting ring 51 via a pin structure 53. This hinged connection allows the speaker structure 52 to rotate or adjust within a certain angle range to adapt to different installation requirements or sound propagation directions.

[0074] The pin structure 53 serves as the rotating shaft connecting the horn structure 52 and the connecting ring 51, providing support and rotational guidance. Through the pin structure 53, the horn structure 52 can be flexibly adjusted relative to the connecting ring 51 while maintaining electrical connection.

[0075] The snap-fit ​​54 is another connection method between the horn structure 52 and the connecting ring 51, providing additional fixation. After the horn structure 52 is adjusted to fit snugly against the connecting ring 51 via the pin structure 53, the snap-fit ​​54 can securely lock it onto the connecting ring 51, preventing the horn structure 52 from shifting under vibration or external force.

[0076] In summary, the working principle of speaker assembly 5 is to fix the assembly in the required position through connecting ring 51, and then provide electrical signals to speaker structure 52 through circuit board 2. After receiving the electrical signals, speaker structure 52 can be flexibly adjusted not only through pin structure 53, but also fixedly adjusted by clip 54 on connecting ring 51, thereby completing the entire sound production process.

[0077] To further explain, the speaker structure 52 includes a protective cover 521, a speaker 522, and a protective shell 523 that are stacked on top of each other in sequence.

[0078] The speaker 522 is covered by the protective cover 521 at the sound output end, and the speaker 522 is covered by the protective shell 523 at the connection end. The wires at the connection end of the speaker 522 pass through the protective shell 523 and are electrically connected to the circuit board 2.

[0079] like Figures 2-3 As shown, a protective cover 521 and a protective shell 523 are added to the front and rear of the speaker 522 and fixed together, so that one end of its outer periphery is hinged to the outer periphery of the first mounting port 13. This design aims to protect the speaker 522 from external physical damage, help maintain the clarity and purity of the sound quality, and provide a convenient way to open and close.

[0080] To further explain, the pin structure 53 includes a pin body 531 and a mounting body 532;

[0081] One end of the pin body 531 is provided with a pressing port 5310, and the other end of the pin body 531 is a closed end. The closed end of the pin body 531 has a snap-fit ​​part 5311 protruding outward.

[0082] A reset compression spring 5312 is installed inside the main body 531 of the pin shaft. A pressing part 5313 is installed at the upper end of the reset compression spring 5312. The pressing part 5313 can be movably passed through the pressing port 5310. The lower end of the reset compression spring 5312 abuts against the closed end.

[0083] The mounting body 532 is fixedly installed on the connecting ring 51. The side wall of the mounting body 532 is provided with a connection clearance opening 5320, and the two ends of the connection clearance opening 5320 are provided with connection bayonets 5321.

[0084] The two ends of the pin body 531 are rotatably mounted on the connecting slot 5321 via the pressing part 5313 and the snap-fit ​​part 5311 respectively, and the side wall of the pin body 531 is fixedly connected to the horn structure 52.

[0085] Specifically, such as Figure 4 As shown, the mounting body 532 is fixedly mounted on the connecting ring 51, providing a mounting base for the pin body 531. A connection clearance opening 5320 on its side wall allows the pin body 531 to move and adjust as necessary during installation. Furthermore, connection slots 5321 at both ends inside the connection clearance opening 5320 are used to engage with the locking portion 5311 and pressing portion 5313 of the pin body 531, enabling the pin body 531 to rotate and be fixed on the mounting body 532. Moreover, a return compression spring 5312 installed inside the pin body 531 provides elastic support for the pressing portion 5313. When the pressing portion 5313 is pressed by an external force, it compresses the return compression spring 5312 and moves inward; when the external force is released, the return compression spring 5312 pushes the pressing portion 5313 back to its original position, thereby realizing the reciprocating motion of the pressing portion 5313. Therefore, the design of the pin structure 53 makes the disassembly and reassembly of the horn structure 52 simple and convenient, reducing maintenance costs and time costs.

[0086] To further explain, the hollow structure 1 is fixedly provided with a pair of main support legs 3 and a pair of auxiliary support legs 4 on its outer periphery;

[0087] The pair of main support legs 3 are arranged longitudinally, and the pair of secondary support legs 4 are arranged laterally.

[0088] Specifically, the main supporting feet 3 are arranged in a longitudinal direction, i.e., they extend along the height direction of the hollow structure 1. This design enables the main supporting feet 3 to effectively bear the longitudinal pressure from the weight of the device and possible external forces (such as impact forces when placing or moving), providing stable support and ensuring that the entire device can be placed smoothly on a desktop or other flat surface. The auxiliary supporting feet 4, on the other hand, are arranged in a transverse direction, i.e., they extend along the width direction of the hollow structure 1. This design enables the auxiliary supporting feet 4 to provide additional support and stability when the device is subjected to lateral forces or torques, which helps to prevent the sound box from moving or toppling due to vibration during playback, ensuring the stability of sound quality and safety of use.

[0089] The technical principles of the present application are described above in conjunction with specific embodiments. These descriptions are only intended to explain the principles of the present application and cannot be interpreted in any way as a limitation on the scope of protection of the present application. Based on the explanations herein, those skilled in the art can conceive of other specific embodiments of the present application without having to exert creative effort, and these equivalent variations or replacements are all included within the scope defined by the claims of the present application.
