[0025] Figure 1 It is a schematic structural diagram of a sound box shown in some embodiments of this specification.

[0026] In some embodiments, as Figure 1 shown, the sound box includes an upper cover 10, a box body 20, a lower cover 30, a speaker 40, a passive radiator 50, a first sealing ring 60, a second sealing ring 70 and a storage rack 80. The upper cover 10 is fixedly connected to the speaker 40. The box body 20 is made of a transparent material, located between the upper cover 10 and the lower cover 30, and is detachably connected to the upper cover 10 and the lower cover 30 respectively. The passive radiator 50 is fixedly connected to the lower cover 30 and is located inside the box body 20. The first sealing ring 60 is located between the upper cover 10 and the box body 20. The second sealing ring 70 is located between the lower cover 30 and the box body 20; the first sealing ring 60 and the second sealing ring 70 make the inside of the box body 20 in a sealed state. The storage rack 80 is fixedly connected to the first sealing ring 60 and is located inside the box body 20, and is configured to place a decorative piece 90.

[0027] Figure 2 It is a schematic structural diagram of the upper cover shown in some embodiments of this specification; Figure 3 It is a schematic structural diagram of the box body shown in some embodiments of this specification; Figure 4 It is a schematic structural diagram of the lower cover shown in some embodiments of this specification.

[0028] The upper cover 10 refers to the structure located at one end of the sound box and connecting the speaker and the box body. In some embodiments, as Figure 2 shown, the upper cover 10 is a circular and hollow structure. The shape of the upper cover 10 can also be other shapes, such as, the outside is square and the hollow position is circular to cooperate with the speaker 40. The speaker 40 is located in the hollow position of the upper cover 10 so that the sound-emitting part (such as the speaker diaphragm) is exposed. The upper cover 10 is also provided with threaded holes 11 connected to the speaker 40 (such as connected to the mounting bracket of the speaker), and the upper cover 10 and the speaker 40 are fixedly connected by screws and the threaded holes 11. The upper cover 10 and the speaker 40 can also be fixed by gluing, buckling, etc. The material of the upper cover 10 can be wood material, plastic material, composite material, etc., which is not limited here.

[0029] The box body 20 refers to the housing of the sound box. The box body 20 can prevent sound short-circuit. Sound short-circuit means that since the sound waves emitted by the speaker are in antiphase front and back, if there is no box body, the sound waves on the front and back sides will cancel each other out, resulting in a decrease in low-frequency sound pressure and an increase in distortion. The box body 20 is equivalent to a sound-emitting cavity, which can seal the antiphase sound waves emitted from the rear side of the speaker, or make it interact with the in-phase sound waves through design, thereby improving the low-frequency effect.

[0030] The detachable connection between the box body 20 and the upper cover 10 and the lower cover 30 can include but is not limited to snap connection, threaded connection, etc. In some embodiments, as Figure 3 shown, when both ends of the box body 20 are circular, the first thread 21-1 and the second thread 21-2 are provided at both ends of the box body 20, and the upper cover 10 and the lower cover 30 are threadedly connected to the box body 20. Exemplarily, external threads are provided at both the upper end and the lower end of the box body 20, and the upper cover 10 and the lower cover 30 are respectively provided with internal threads matching the external threads. In some embodiments, when the shapes of the upper cover 10 and the lower cover 30 are square or other shapes, the box body 20 and the upper cover 10 and the lower cover 30 can be connected by snap connection or other detachable connections. For example, the upper cover 10 and the lower cover 30 are provided with flip buckles of the snap, and the box body 20 is provided with a snap groove, and the flip buckle is snapped into the snap groove for fixation.

[0031] Most traditional box bodies are fixed by general screws or gluing. In some embodiments of this specification, the box body is connected by threads, which makes the assembly convenient and improves the assembly efficiency; at the same time, it is also convenient for customers to disassemble the box body.

[0032] The material of the box body 20 is a transparent material, such as transparent plastic, crystal, glass, transparent ceramic, etc. In some embodiments, the material of the box body 20 is borosilicate glass. Borosilicate glass is mainly composed of silicates with a borate tetrahedron structure, and has the advantages of high transparency, relatively high mechanical strength, good refractive index and dispersion performance.

[0033] In audio products, most of the commonly used enclosures are made of plastic. Traditional injection-molded enclosures have appearance defects such as weld lines and air marks, and are also prone to scratches, increasing the number of scratches on the enclosure. Compared with injection-molded audio enclosures, the mold cost of glass is lower, and at the same time, the appearance of glass material is easier to control, and the light transmittance is also greatly improved, with a high appearance grade. Therefore, using borosilicate glass as the material of the enclosure can reduce the mold cost and improve the appearance grade.

[0034] In some embodiments, the shape of the enclosure 20 includes at least one of a cuboid shape, a cube shape, a conical shape, a cylindrical shape (as Figure 3 shown), a prismatic shape, a spherical shape, and an irregular shape. When the enclosure 20 is threadedly connected to the upper cover 10 and the lower cover 30, the shape of the enclosure 20 can be such that the middle part has the aforementioned shapes such as a cuboid shape, and the two ends are circular shapes that cooperate with the upper cover 10 and the lower cover 30.

[0035] In some embodiments, when the shape of the enclosure 20 is at least one of a conical shape, a prismatic shape, and an irregular shape, the diameter of the upper cover 10 is different from the diameter of the lower cover 30. When the enclosure 20 is threadedly connected to the upper cover 10 and the lower cover 30, and the upper cover 10 and the lower cover 30 are circular, for convenient detachable connection with the upper cover 10 and the lower cover 30, when the shape of the enclosure 20 is asymmetric up and down, the diameter of the upper cover 10 is different from the diameter of the lower cover 30.

[0036] When the shape of the enclosure 20 is different, the sound wave propagation paths of the speakers are different, so the timbre of the audio is also different. At the same time, designing the enclosures of the audio in various shapes can increase the ornamental value of the enclosure appearance. In some embodiments of this specification, the shape of the enclosure of the audio can be diverse, and the enclosure 20 is detachably connected to the upper cover 10 and the lower cover 30, enabling the manufacturer to customize enclosures of different sizes and shapes for interchangeable assembly according to the needs of different customers, and allowing customers to replace the enclosures according to their own needs; realizing variable enclosures, improving the sound quality, and increasing the fun.

[0037] The lower cover 30 refers to the structure located at the other end of the audio and connected to the enclosure 20. In some embodiments, as Figure 4 shown, the lower cover 30 is a circular hollow structure, and the passive diaphragm 50 is located in the hollow position of the lower cover 30 to facilitate the vibration and sound emission of the passive diaphragm 50. The material of the lower cover 30 is similar to that of the upper cover 10 and will not be elaborated here.

[0038] In some embodiments, as Figure 4As shown in the figure, the lower cover 30 includes an inner ring 31 and an outer ring 32. A notch is formed between the inner ring 31 and the outer ring 32. The box body 20 is arranged in the notch, and the inner ring 31 is fixedly connected to the passive diaphragm 50. The inner ring 31 and the passive diaphragm 50 can be fixedly connected by threaded connection, adhesive connection, snap connection, etc. The material of the lower cover 30 can be wood material, plastic material, composite material, etc., which is not limited here.

[0039] In some embodiments of this specification, by setting the lower cover 30 as an inner ring and an outer ring, the lower cover 30 can be connected to both the passive diaphragm 50 and the box body 20 at the same time, and the box body and the passive disk do not contact each other, which can avoid interference when the passive disk vibrates.

[0040] The speaker 40 is the main sound - emitting device of the audio. The speaker can also be called a loudspeaker, a speaker box, a loudspeaker, and is a transducer and an electronic device that converts an electronic signal into sound. Exemplarily, the speaker is composed of a magnet, a coil, a speaker diaphragm, and a mounting bracket; when an electrical signal is input from a sound source, an electric current passes through the coil to generate a magnetic field. The coil is subjected to the force of the magnetic field and will vibrate. The vibrating speaker diaphragm will push the surrounding air to generate sound wave vibrations, thereby generating sound output.

[0041] The passive diaphragm 50 refers to a component that compresses the air in the acoustic cavity (i.e., the enclosed space of the box body) and vibrates passively to generate sound when relying on the speaker to emit sound. The structure of the passive diaphragm 50 can be an empty paper cone, a surround, etc. The passive diaphragm 50 is located inside the box body, and the passive diaphragm 50 is fixedly connected to the lower cover 30 and is located inside the box body 20; for the connection method, refer to the above text.

[0042] By setting the passive disk, the coupling effect between the passive diaphragm and the speaker can be utilized to extend the lower limit of the low - frequency range and improve the sound quality effect.

[0043] The first sealing ring 60 and the second sealing ring 70 are annular components for sealing. In some embodiments, the first sealing ring 60 is located between the upper cover 10 and the box body 20. The second sealing ring 70 is located between the lower cover 30 and the box body 20; the first sealing ring 60 and the second sealing ring 70 make the inside of the box body 20 in a sealed state. Exemplarily, the first sealing ring 60 and the second sealing ring 70 are elastic materials, such as rubber and silica gel; after being extruded and deformed, the elastic materials block the gaps at the joints, thereby making the inside of the box body 20 in a sealed state.

[0044] The storage rack 80 refers to a component configured to place the decorative piece 90. The storage rack 80 is fixedly connected to the first sealing ring 60 and is located inside the box body 20.

[0045] The decorative piece 90 refers to a component used for viewing and decoration; for example, the decorative piece 90 can be a craft, an ornament, a photo frame, etc. The decorative piece 90 can have a variety of shapes, and can also be a shape that matches the box 20; for example, if the box 20 is spherical, the decorative piece 90 is also spherical (such as a crystal ball ornament); for another example, if the box 20 is a rectangular parallelepiped, the decorative piece 90 is also a rectangular parallelepiped (such as a photo frame).

[0046] The detachable structure of the box makes it easy to put decorative parts into the speaker box. Customers can put in different decorative parts according to their personal preferences, which improves the personalized decorative effect of the speaker.

[0047] In some embodiments, the decorative element includes a light emitting device. The light emitting device may be an LED lamp, a neon lamp, or other light emitting ornaments (such as a crystal ball). The light emitting device may be placed on the storage table of the storage rack, or may be set in other locations, such as being wrapped around the suspension rod of the storage rack, or being located on the inner wall of the box, etc.

[0048] In some embodiments of the present specification, the transparent material of the box is combined with the light-emitting device of the decorative element to achieve a good viewing effect, thereby improving the decorative effect of the audio system.

[0050] In some embodiments, Figure 5 As shown, the storage rack 80 includes a connecting ring 81, at least three suspension rods 82 and a storage platform 83. The connecting ring 81 is fixedly connected to the at least three suspension rods 82, and the at least three suspension rods 82 are fixedly connected to the storage platform 83. Figure 1 As shown, a groove is provided on one side of the first sealing ring 60 close to the box axis A, and the connecting ring 81 is fixedly connected to the groove. The placement surface of the storage table 83 is perpendicular to the box axis A; the placement surface is configured to contact the decorative element 90 .

[0051] The connecting ring 81 is configured as a structure for fixing the storage rack 80 to the sound system, such as the connecting ring 81 is fixedly connected to the speaker or the first sealing ring. The material of the connecting ring 81 can be plastic, wood, etc.

[0052] The suspension rod 82 is configured as a structure for suspending and fixing the storage table 83. The material of the suspension rod 82 can be various, such as plastic or rope. When the suspension rod 82 is a rope, it is convenient to move the decorative piece.

[0053] The storage table 83 is arranged to be in contact with the decoration piece 90 and to place the decoration piece 90 thereon.

[0054] The connecting ring 81 and the suspension rod 82, and the suspension rod 82 and the placement table 83 can be fixedly connected in various ways, such as by gluing, integrally molding, or tying with a rope (the suspension rod 82 is a rope), etc. In some embodiments, the connecting ring 81 and the suspension rod 82, and the suspension rod 82 and the placement table 83 can be detachably fixed. For example, the connecting ring 81 and the placement table 83 are provided with hooks, the suspension rod 82 is a rope, and the hooks hook the rope for fixation. The groove of the first sealing ring 60 and the connecting ring 81 can be fixedly connected by gluing.

[0055] In some embodiments, such as Figure 1 shown, the shelf 80 further includes a third sealing ring 84, and the third sealing ring 84 is located between the connecting ring 81 and the speaker 40. The structure and material of the third sealing ring 84 are similar to those of the second sealing ring 70. Refer to the content of the second sealing ring 70 above.

[0056] There may be a gap between the inner side of the connecting ring 81 and the speaker 40. By providing the third sealing ring 84, it can further ensure that the box body is in a sealed state and ensure the sound effect of the speaker.

[0057] In some embodiments, such as Figure 5 、 Figure 6 shown, the connecting ring 81 is provided with a protrusion 81-1, and the side of the speaker is provided with an L-shaped groove 41 that cooperates with the protrusion 81-1.
