[0002] An audio system is a device that converts electrical signals into sound signals, primarily used to amplify and reproduce audio, allowing people to hear clear, layered sound. Structurally, core components typically include speakers, amplifiers, and possibly decoding modules. Based on their purpose and form, audio systems can be categorized into various types, such as home audio systems, portable audio systems, and professional audio systems. Their sound quality is usually closely related to factors such as the quality of the speaker drivers, crossover design, and cabinet structure. Good audio systems can better reproduce the timbre, dynamics, and stereo effect of sound.

[0003] In the existing technology, external clamping devices for audio equipment have problems such as fixed clamping angle, easy loosening of connections, poor adaptability to irregularly shaped parts, bulky structure and insufficient heat dissipation. At the same time, the internal components of the audio equipment are messy, and there is obvious space conflict between the clamping, circuit and speaker, which affects the acoustic performance and maintenance efficiency. The appearance also lacks brand display and protection integration. Utility Model Content

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figures 1 to 3As shown in the figure, this is an embodiment of the present invention, which relates to a rotatable clamping assembly, including a clamping unit 10 and a rotating connecting unit 20 connected to the clamping unit 10; the clamping unit 10 includes an upper clamping arm 40 and a lower clamping arm 50 arranged opposite to each other, the upper clamping arm 40 and the lower clamping arm 50 forming a clamping space 11 for clamping a component to be fixed; the rotating connecting unit 20 includes a top rotating seat 60 and an annular support body 70; the upper surface of the top rotating seat 60 is provided with an annular guide groove 61, and the bottom surface of the lower clamping arm 50 is provided with an annular boss 51 that rotatably engages with the annular guide groove 61, so that the clamping unit 10 can rotate relative to the rotating connecting unit 20 about a vertical axis; the annular support body 70 is connected below the top rotating seat 60.

[0031] Specifically, the rotating engagement structure of the annular guide groove 61 and the annular boss 51 enables the clamping unit 10 to rotate flexibly in the circumference relative to the rotating connection unit 20, with a smooth and uninterrupted rotation process; the variable clamping space 11 enclosed by the upper clamping arm 40 and the lower clamping arm 50 can accommodate different sizes of parts to be fixed; the modular design of the clamping unit 10 and the rotating connection unit 20 results in a compact structure, effectively improving space utilization while ensuring connection stability and providing a reliable angle adjustment function for the parts to be fixed.

[0032] like Figure 2 As shown, the upper clamping arm 40 is connected to the lower clamping arm 50 at both ends by first fasteners 41, and the upper clamping arm 40 is connected to the lower clamping arm 50 through the first fasteners 41. Specifically, the upper clamping arm 40 is detachably connected to the lower clamping arm 50 at both ends by the first fasteners 41, which facilitates quick adjustment of the clamping space 11 size to meet the clamping requirements of different specifications of parts to be fixed; the connection method of the fasteners ensures the structural strength of the upper clamping arm 40 and the lower clamping arm 50, avoids clamping loosening caused by external forces, and simplifies the assembly and maintenance process, reducing the later maintenance cost.

[0033] like Figure 3 As shown, the bottom of the lower clamping arm 50 is provided with an annular base 52, and the upper part of the annular base 52 is connected to the annular boss 51. Several second fasteners 53 are connected to the outer periphery of the annular base 52. Specifically, the annular base 52 increases the contact area with the top rotating seat 60, disperses the stress generated by the clamping force, and improves the structural load-bearing capacity; the multiple sets of second fasteners 53 on the outer periphery are evenly distributed, making the connection between the lower clamping arm 50 and the rotating connection unit 20 more reliable, preventing loosening or displacement during rotation or clamping, and enhancing the overall structural stability.

[0034] like Figure 2 and Figure 3As shown, the inner side of the annular guide groove 61 is provided with several third fasteners 62, and the outer edge of the annular guide groove 61 is evenly distributed with fastening connection holes 63; the third fasteners 62 pass through the annular guide groove 61 and connect with the mounting part 73 of the annular support body 70; the fastening connection holes 63 are adapted to connect with the second fasteners 53. Specifically, the annular guide groove 61 adopts a double connection structure of inner third fasteners 62 and outer fastening connection holes 63: the inner connection ensures the core strength of the annular guide groove 61 and the annular support body 70, and the outer connection further strengthens the circumferential structure and improves the overall rigidity of the rotating connection unit 20; the double connection design can also achieve precise positioning during installation, ensure coaxiality, avoid rotational jamming, and ensure smooth rotation.

[0035] like Figure 2 As shown, the inner wall of the upper clamping arm 40 is provided with a first anti-slip layer 42, and a first arc-shaped groove 43 is formed on the inner side of the first anti-slip layer 42; the inner wall of the lower clamping arm 50 is provided with a second anti-slip layer 54, and a second arc-shaped groove 55 is formed on the inner side of the second anti-slip layer 54. Specifically, the first anti-slip layer 42 and the second anti-slip layer 54 effectively increase friction and prevent the part to be fixed from slipping; the first arc-shaped groove 43 and the second arc-shaped groove 55 are adapted to the part to be fixed with a cylindrical or other arc-shaped contour, improving the clamping fit and expanding the application range; at the same time, the first anti-slip layer 42 and the second anti-slip layer 54 can buffer the clamping impact force and protect the surface of the part to be fixed from damage.

[0036] like Figure 2 As shown, both the first anti-slip layer 42 and the second anti-slip layer 54 are rubber layers, silicone layers, or polyurethane layers. Specifically, the anti-slip layers made of rubber, silicone, or polyurethane have good flexibility and cushioning properties, further enhancing the anti-slip effect, absorbing vibration, and reducing collision noise; moreover, the above materials are wear-resistant and aging-resistant, extending the service life of the components and reducing replacement costs.

[0037] like Figure 1 and Figure 2 As shown, the annular support 70 has a central mounting hole 71 in its center, and several spaced-apart perforated windows 72 are provided on the circumferential sides of the central mounting hole 71. The perforated windows 72 are fan-shaped or rectangular. Specifically, the central mounting hole 71 of the annular support 70 provides installation space for the speaker 32, improving the component's expandability; the fan-shaped or rectangular perforated windows 72 effectively reduce weight, lower the overall mass, and facilitate installation; the perforated structure increases the heat dissipation area, prevents heat accumulation, and ensures operational stability; at the same time, the reasonable mechanical structure distribution ensures the strength of the annular support 70 and avoids insufficient rigidity caused by the perforations.

[0038] like Figures 4 to 6As shown, an audio device includes an audio body 30, which includes a housing 80, a rotatable clamping assembly, a circuit board 31, and a speaker 32. The housing 80 is a conical hollow cavity with an axially penetrating receiving cavity 81 inside. The top of the housing 80 has a mounting surface 82. The top rotating seat 60 of the rotatable clamping assembly is connected to the upper surface of the mounting surface 82. The circuit board 31 is mounted behind the receiving cavity 81 and is electrically connected to the speaker 32. The speaker 32 is fixed inside the housing 80.

[0039] Specifically, the conical hollow cavity enables the axial layout of the clamping, circuitry, and sound-generating components: the conical shell conforms to acoustic diffusion design, improving sound quality; the rotatable clamping assembly supports flexible adjustment of the angle of external devices, expanding usage scenarios; the partitioned layout of each component facilitates operation while ensuring acoustic performance, achieving functional integration and simplifying the user's workflow. In this embodiment, the electrical connection between the circuit board 31 and the speaker 32 is achieved using conventional methods in the art, such as wire welding, connector adaptation, or flexible circuit board connection. These specific connection structures are existing technologies and do not affect the core technical solution of this embodiment, so they will not be described in detail here.

[0040] like Figure 6 As shown, the annular support 70 of the rotatable clamping assembly is installed inside the receiving cavity 81, and the speaker 32 passes through the central mounting hole 71 of the annular support 70. Specifically, the annular support 70 is installed in the speaker receiving cavity 81, and the speaker 32 passes through the central mounting hole 71, making full use of the central space, integrating the clamping and sound-emitting structures, greatly improving the utilization rate of internal space, and making the whole more compact.

[0041] like Figure 4 and Figure 5 As shown, the front opening of the outer casing 80 is provided with a decorative front cover 83, and its rear end is provided with a decorative rear cover 84. The decorative rear cover 84 is provided with a logo surface 85 for displaying the brand logo. Specifically, the decorative front cover 83 and the decorative rear cover 84 effectively protect the internal components, prevent foreign objects from entering, and improve product durability; the brand logo surface 85 of the decorative rear cover 84 enhances brand recognition, takes into account both aesthetic appearance and brand promotion needs, and at the same time provides additional support for the internal structure.

[0042] The working logic of this utility model is as follows:

[0043] The upper clamping arm 40 and the lower clamping arm 50 are connected by the first fastener 41 to form a variable clamping space 11; the inner anti-slip layer of rubber, silicone or polyurethane and the arc groove enhance the clamping stability, adapt to the arc-shaped parts to be fixed, and buffer the impact.

[0044] The annular boss 51 of the lower clamping arm 50 is embedded in the annular guide groove 61 of the top rotating seat 60 to achieve circumferential rotation; the annular guide groove 61 is connected to the annular support body 70 through the inner third fastener 62 and the outer fastening connection hole 63 to ensure rigidity and coaxiality; the central mounting hole 71 of the annular support body 70 supports functional expansion, and the hollow window 72 reduces weight and dissipates heat.

[0045] The conical hollow housing provides an axial receiving cavity 81, the top rotating seat 60 of the rotatable clamping assembly is connected to the top of the housing, and the annular support 70 is embedded in the receiving cavity 81; the speaker 32 passes through the central mounting hole 71, and the circuit board 31 is located behind the receiving cavity 81 and is electrically connected to the speaker 32.

[0046] External devices are fixed by clamping components and can be adjusted around the vertical axis; the speaker 32 vibrates to produce sound, which is diffused through the conical cavity; the circuit board 31 coordinates the control signals; the decorative front cover 83 and the decorative back cover 84 protect the internal components; and the logo surface 85 on the back cover displays the brand.

[0047] The rotatable clamping assembly of this utility model has an upper clamping arm 40 and a lower clamping arm 50 enclosing a variable clamping space 11 through a first fastener 41. The first anti-slip layer 42, the second anti-slip layer 54, and the corresponding first arc groove 43 and second arc groove 55 on the inner sides of the two arms not only improve the fit and anti-slip ability of the arc-shaped parts to be fixed, but also buffer the clamping impact. The bottom annular boss 51 of the lower clamping arm 50 is embedded in the annular guide groove 61 of the top rotating seat 60, so as to realize the smooth circumferential rotation of the clamping unit 10 around the vertical axis. The third fastener 62 on the inner side of the annular guide groove 61 connects to the annular support body 70, and the outer fastening connection hole 63 is adapted to the second fastener 53 of the annular base 52 of the lower clamping arm 50, forming a double connection and reinforcement structure to ensure rotational coaxiality and overall rigidity. The central mounting hole 71 of the annular support body 70 is reserved for functional expansion. The circumferential fan-shaped or rectangular hollow window 72 effectively reduces weight and dissipates heat, optimizing the structural mechanics and thermal management performance.

[0048] This utility model features a conical hollow outer shell 80 for the speaker, which forms an axially penetrating cavity 81. A top mounting surface 82 connects to a top rotating seat 60 of a rotatable clamping assembly. An internal annular support 70 is embedded in the cavity 81. The speaker 32 passes through a central mounting hole 71, and the circuit board 31 is rear-mounted. These three components work in a coordinated manner to avoid functional interference and ensure acoustic performance. A decorative front cover 83 closes the front opening, and a decorative rear cover 84 features a brand logo surface 85, protecting internal components and enhancing brand recognition. Through modular optimization of the clamping assembly and its collaborative design with the speaker system, this invention solves problems such as fixed clamping angles, loose connections, spatial conflicts, and monotonous appearance found in traditional solutions. It achieves a comprehensive improvement in flexible angle adjustment, stable clamping, compact layout, sound quality assurance, and brand presentation, significantly enhancing product practicality and market competitiveness.

[0049] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
