[0002] With the increasing popularity of audio equipment, consumers are demanding higher and higher standards for the sound quality, structural stability, ease of use, and appearance design of audio equipment.

[0003] Many audio systems on the market today suffer from several shortcomings: First, the wiring structure is poorly designed, with an excessive number of terminals or a cluttered layout, leading to complex wiring connections, poor contact, and consequently, audio signal transmission and sound distortion. Second, the connection methods for various components are cumbersome, resulting in low assembly efficiency and poor connection stability. During use, vibrations can cause components to loosen, affecting audio performance. Third, heat dissipation is inadequate, as the heat generated by internal components cannot be dissipated in time. Prolonged exposure to high temperatures can cause component performance degradation and shorten the lifespan of the audio system. Fourth, the design lacks distinctiveness, with poor integration between decorative and functional components, making it difficult to balance practicality and aesthetics. Fifth, maintenance is inconvenient, with some components difficult to disassemble, leading to high costs for subsequent repairs and component replacements. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a speaker with a simple wiring structure, stable connection, good heat dissipation, beautiful appearance and convenient maintenance.

[0005] The present invention adopts the following technical solution: A speaker with a terminal block includes a speaker body, which comprises a decorative cover, a speaker assembly, a first cavity component, a second cavity component, and a rear cover connected in sequence. The first cavity component has several through holes on its outer periphery, and a terminal block is vertically disposed on the side of each through hole near the second cavity component. Each terminal block is electrically connected to the speaker assembly via a wire. Two wiring holes are respectively provided on both sides of the terminal block, and a reinforcing rib is provided between the two wiring holes on the end face of the terminal block. A T-shaped reinforcing rib is provided on the side of the terminal block away from the reinforcing rib.

[0006] A further improvement to the above technical solution is that the decorative cover has a radially distributed hollow structure, and the center of the decorative cover is provided with a decorative part with a mark.

[0007] A further improvement to the above technical solution is that the hollow structure is symmetrically distributed and the shape of the hollow structure is arc-shaped.

[0008] A further improvement to the above technical solution is that the outer side of the decorative cover is provided with a plurality of first connecting holes at equal intervals, the first connecting holes being used to connect with locking bolts.

[0009] A further improvement to the above technical solution is that a snap-fit ​​ring is provided on the outer periphery of the horn assembly, and a plurality of avoidance arc-shaped holes for avoiding locking bolts are equidistantly distributed on the outer edge of the snap-fit ​​ring. Weight reduction holes located on the snap-fit ​​ring are respectively opened on both sides of the avoidance arc-shaped holes.

[0010] A further improvement to the above technical solution is that the first cavity component has a snap-fit ​​groove near the front end of the speaker assembly, which engages with the snap-fit ​​ring. A plurality of second connection holes are provided at equal intervals on the outer side of the snap-fit ​​groove. The second connection holes are connected to the first connection holes by locking bolts.

[0011] A further improvement to the above technical solution is that the rear end of the first cavity component is provided with a plurality of heat sinks, the plurality of heat sinks are radially distributed, and the heat sinks are connected to a positioning ring, and the outer side of the positioning ring is provided with a plurality of positioning pins.

[0012] A further improvement to the above technical solution is that the front edge of the second cavity component is provided with a positioning groove, the positioning groove is inserted and engaged with a positioning ring, and the outside of the positioning groove is provided with a positioning slot that engages with a positioning post.

[0013] A further improvement to the above technical solution is that a plurality of connecting ribs are equidistantly distributed at the rear end of the second cavity component, and one end of each connecting rib is connected to a chuck.

[0014] A further improvement to the above technical solution is that a fitting groove is provided on the end face of the rear cover near the second cavity component, and the inner diameter of the fitting groove is adapted to the outer diameter of the chuck for engaging with the chuck.

[0015] The beneficial effects of this utility model are as follows: The speaker body of this utility model adopts a structure in which a decorative cover, a speaker assembly, a first cavity component, a second cavity component, and a rear cover are connected in sequence. It is equipped with multiple precise connection designs: such as the bolt engagement between the first connecting hole of the decorative cover and the second connecting hole of the first cavity component, the engagement between the speaker assembly locking ring and the locking groove of the first cavity component, the insertion between the positioning ring (pole) of the first cavity component and the positioning groove (slot) of the second cavity component, and the engagement between the chuck of the second cavity component and the fitting groove of the rear cover. This ensures that each component is firmly connected, avoids loosening caused by vibration, simplifies the assembly process, and can be installed and disassembled without complicated tools, which greatly improves production efficiency and the convenience of later maintenance. The through-hole of the first cavity component provides dedicated installation space for the terminal block. The single terminal block design simplifies the circuit structure and reduces the risk of poor contact. The double wiring holes on both sides of the terminal block adapt to external wires of different specifications, improving equipment compatibility. The reinforcing vertical ribs between the holes enhance the structural strength of the terminal block, prevent deformation during insertion and removal, and limit the wires to ensure stable audio signal transmission, reducing sound quality distortion from the source. The decorative cover features a radially symmetrical arc-shaped hollow structure, which ensures unobstructed sound wave propagation and low loss, guaranteeing clear and full sound quality and consistent listening experience from all directions, while also possessing aesthetic value. The radially shaped heat sink at the rear of the first cavity component maximizes the heat dissipation area, evenly conducts heat from internal components (such as the power amplifier module), effectively controls the internal temperature, avoids performance degradation caused by high temperature, and extends the lifespan of the speaker. The weight-reducing holes in the speaker assembly snap ring and the equidistant connecting ribs of the second cavity component significantly reduce the weight of the components and the overall weight of the speaker without affecting the structural strength, making it easier to move and place; at the same time, it reduces the amount of material used, lowers the production and manufacturing costs, and balances performance and economy. The decorative cover features a radial, arc-shaped hollow design paired with a central decorative section with a logo, enhancing both the visual appeal and the brand's recognition. The overall structure is neat and orderly when all components are connected, and the tight fit between the back cover's groove and the chuck prevents dust and moisture from entering, protecting internal components and achieving the dual value of aesthetic appeal and practical protection.

[0021] like Figures 1 to 7As shown in the figure, this is an embodiment of the present invention, which relates to an audio device with a terminal block. The audio device includes an audio body 10, which includes a decorative cover 20, a speaker assembly 30, a first cavity component 40, a second cavity component 50, and a rear cover 60 connected in sequence. The outer periphery of the first cavity component 40 is provided with several through holes 41, and a terminal block 42 is vertically arranged on the side of the through hole 41 near the second cavity component 50. The terminal block 42 is provided as one, and the terminal block 42 is electrically connected to the speaker assembly 30 through a wire (not shown in the figure). Two wiring holes 43 are respectively provided on both sides of the terminal block 42, and a reinforcing rib 44 is provided between the two wiring holes 43 on the end face of the terminal block 42. A T-shaped reinforcing rib 70 is provided on the side of the terminal block 42 away from the reinforcing rib 44. Specifically, the through hole 41 on the outer periphery of the first cavity component 40 provides dedicated installation space for the terminal block 42, allowing the terminal block 42 to be laid out more closely to the internal wiring, avoiding messy tangling of wires (not shown in the figure), and improving the neatness of the internal structure. On the other hand, the through hole 41 can assist internal air circulation, alleviate the heat dissipation pressure during component operation, and extend the component's service life. By providing only one terminal block 42 and electrically connecting it to the speaker assembly 30 via a wire (not shown in the figure), the wiring structure is simplified, the number of wiring connection points is reduced, the risk of poor contact is lowered, and the stability of audio signal transmission is ensured. At the same time, the single-terminal design saves internal space, making the overall size of the speaker more compact and adaptable to more installation scenarios. The two wiring holes 43 on both sides of the terminal block 42 can meet the access requirements of external connection cables of different specifications, improving the compatibility of the audio system. For example, it can connect the audio input cable and the ground wire at the same time, or adapt to external devices with different impedances. The reinforcing rib 44 between the two wiring holes 43 can enhance the structural strength of the terminal block 42 end face, avoid the deformation of the terminal due to frequent insertion and removal of wires (not shown in the figure), and extend the service life of the terminal block 42. At the same time, the reinforcing rib 44 can play a certain limiting role for the wires (not shown in the figure), reducing the impact of wire (not shown in the figure) shaking on the connection stability. like Figure 1 and Figure 3As shown, the decorative cover 20 has a radially distributed perforated structure 21, and the center of the decorative cover 20 has a decorative part 22 with an identifier. Specifically, the radially distributed perforated structure 21 has excellent acoustic transparency, does not obstruct the propagation of sound waves emitted by the speaker assembly 30, minimizes sound wave loss during propagation, and ensures clear and full sound quality, especially highlighting the mid-low frequency performance of the speaker. From an aesthetic point of view, the radial shape is layered and design-oriented, enhancing the overall appearance of the speaker and meeting the aesthetic needs of modern consumers for product appearance. The decorative part 22 with an identifier at the center of the decorative cover 20 not only clearly displays the brand logo or product model, enhancing product recognition and helping brand communication, but also serves as a visual focal point, balancing the overall design of the decorative cover 20. Thus, the decorative cover 20 not only fulfills its function of protecting the speaker assembly 30, but also has the dual value of brand promotion and decoration.

[0022] like Figure 1 and Figure 3 As shown, the hollow structure 21 is symmetrically distributed and has an arc shape. Specifically, the symmetrically distributed arc-shaped hollow structure 21 further optimizes the acoustic performance of the speaker. The symmetrical design ensures uniform resistance to sound wave propagation in all directions, avoiding uneven sound wave propagation caused by structural asymmetry, and ensuring a consistent listening experience for listeners in different positions. Compared to a straight line shape, the arc shape reduces sound wave reflection interference, lowers sound wave reflection loss on the surface of the decorative cover 20, and improves the purity of sound quality. In addition, the symmetrical arc structure appears more fluid and natural visually. Combined with the radial distribution, it makes the design of the decorative cover 20 more harmonious and artistic, further enhancing the speaker's aesthetic competitiveness.

[0023] like Figure 3 As shown, the decorative cover 20 has a plurality of first connecting holes 23 equidistantly arranged on its outer side. The first connecting holes 23 are used to connect with locking bolts (not shown in the figure). Specifically, the first connecting holes 23 equidistantly arranged on the outer side of the decorative cover 20 provide precise and uniform installation points for the connection of the decorative cover 20 with other components. The equidistant layout ensures that the force is balanced at each point during connection, avoiding the problem of the decorative cover 20 being tilted or damaged due to excessive local force caused by uneven spacing of the connection points, and improving the firmness of the connection between the decorative cover 20 and the speaker body 10. At the same time, the first connecting holes 23 cooperate with the locking bolts (not shown in the figure) to make the disassembly and installation of the decorative cover 20 more convenient, facilitating the subsequent inspection, cleaning or replacement of the speaker assembly 30, and reducing the difficulty and cost of maintenance.

[0024] like Figure 3As shown, the outer periphery of the speaker assembly 30 is provided with a snap-fit ​​ring 31. The outer edge of the snap-fit ​​ring 31 has several equidistant arc-shaped holes 32 for avoiding locking bolts (not shown in the figure). Weight-reducing holes 33 are respectively opened on both sides of the arc-shaped holes 32 on the snap-fit ​​ring 31. Specifically, the snap-fit ​​ring 31 on the outer periphery of the speaker assembly 30 provides a quick positioning structure for the assembly of the speaker assembly 30 and the first cavity component 40, enabling precise installation without complex measurements and significantly improving assembly efficiency. Simultaneously, the snap-fit ​​connection enhances the sealing of the connection, reducing sound wave leakage from gaps and ensuring the loudness and sound quality of the audio system. The arc-shaped holes 32 on the outer edge of the snap-fit ​​ring 31 precisely avoid the locking bolts (not shown in the figure), preventing interference between the bolts and the snap-fit ​​ring 31, ensuring that the components do not interfere with each other during assembly, and guaranteeing the compactness of the overall structure. The weight reduction holes 33 on both sides of the curved hole 32 effectively reduce the overall weight of the speaker assembly 30 and the total weight of the speaker body 10 without affecting the structural strength of the snap ring 31, making it easier to move and place the speaker. At the same time, the weight reduction holes 33 can reduce the amount of material used, reduce production costs, and also help the speaker assembly 30 dissipate heat, preventing the heat generated by the speaker during long-term operation from affecting performance.

[0025] like Figure 3 As shown, the first cavity component 40 has a snap-fit ​​groove 45 near the front end of the speaker assembly 30, which engages with the snap-fit ​​ring 31. A plurality of second connecting holes 46 are equidistantly arranged on the outer side of the snap-fit ​​groove 45. The second connecting holes 46 are connected to the first connecting holes 23 by locking bolts (not shown in the figure). Specifically, the snap-fit ​​groove 45 at the front end of the first cavity component 40, which engages with the snap-fit ​​ring 31, enables quick snap-fit ​​assembly of the speaker assembly 30 and the first cavity component 40, simplifying the assembly process and improving production efficiency. The tight fit between the snap-fit ​​groove 45 and the snap-fit ​​ring 31 enhances the stability and sealing of the connection, reduces sound leakage and the entry of external impurities, and ensures sound performance. The equidistant second connecting holes 46 on the outer side of the first cavity component 40 engage with the first connecting holes 23 of the decorative cover 20 by locking bolts (not shown in the figure), forming a stable connection between the decorative cover 20, the speaker assembly 30, and the first cavity component 40. The equidistant layout ensures balanced stress at each connection point, avoids component deformation caused by localized stress concentration, and extends the service life of the speaker.

[0026] like Figure 4 and Figure 5As shown, the rear end of the first cavity component 40 is provided with a plurality of heat sinks 47, which are radially distributed and connected to a positioning ring 48. The outer side of the positioning ring 48 is provided with a plurality of positioning pins 49. Specifically, the radially distributed heat sinks 47 at the rear end of the first cavity component 40 maximize the heat dissipation area, quickly transferring the heat generated by internal components (such as the power amplifier module) to the outside, effectively controlling the internal temperature, preventing component performance degradation or damage due to high temperatures, and ensuring stable long-term operation of the audio system. The radial distribution also makes heat dissipation more uniform, avoiding localized overheating. The positioning ring 48 and positioning pins 49 provide precise positioning for the connection between the first cavity component 40 and the second cavity component 50, ensuring accurate positioning during assembly, reducing assembly deviations, and improving the overall structural stability. Simultaneously, the positioning structure simplifies the assembly process, allowing initial docking to be completed without the need for complex tools, thus improving production efficiency.

[0027] like Figure 3 and Figure 7 As shown, the front edge of the second cavity component 50 is provided with a positioning groove 51, which is inserted into the positioning ring 48. The external part of the positioning groove 51 is provided with a positioning slot 52 that mates with the positioning post 49. Specifically, the positioning groove 51 on the front edge of the second cavity component 50 is inserted into the positioning ring 48 of the first cavity component 40, enabling quick docking and initial fixation of the two components. This ensures precise positioning and convenient assembly. The tight fit between the positioning groove 51 and the positioning ring 48 enhances the sealing of the connection between the two components, reducing the entry of dust and moisture and protecting the components. The positioning slot 52 outside the positioning groove 51 mates with the positioning post 49 of the first cavity component 40, further strengthening the connection stability and preventing relative displacement due to vibration during use, thus ensuring the overall stability of the speaker structure. This insertion-fit structure also facilitates subsequent disassembly and maintenance, reducing the difficulty of repair.

[0028] like Figure 4 and Figure 6As shown, a plurality of connecting ribs 53 are evenly distributed at the rear end of the second cavity component 50, and one end of each connecting rib 53 is connected to a chuck 54. Specifically, the evenly distributed connecting ribs 53 at the rear end of the second cavity component 50 effectively reduce the weight of the second cavity component 50 and lower material costs while ensuring the structural strength of the component. At the same time, the rib structure can enhance the component's resistance to deformation and avoid damage caused by external impact. The chuck 54 at one end of the connecting rib 53 provides a reliable snap-fit ​​structure for the connection between the second cavity component 50 and the rear cover 60. The snap-fit ​​method is easy to operate and can fix the rear cover 60 without additional fasteners, simplifying the assembly process and reducing production and maintenance costs. At the same time, the cooperation between the chuck 54 and the rear cover 60 can ensure the internal sealing of the second cavity component 50 and prevent dust and impurities from entering and affecting the performance of internal components.

[0029] like Figure 3 As shown, the rear cover 60 has a fitting groove 61 on its end face near the second cavity component 50. The inner diameter of the fitting groove 61 is adapted to the outer diameter of the chuck 54 for engaging with the chuck 54. Specifically, the fitting groove 61 on the end face of the rear cover 60, which is adapted to the outer diameter of the chuck 54, enables precise engagement between the rear cover 60 and the second cavity component 50. The tight fit effectively prevents external dust and moisture from entering the speaker, protecting internal components from corrosion and extending their service life. At the same time, the engagement structure between the fitting groove 61 and the chuck 54 is simple and reliable, and easy to disassemble, facilitating subsequent inspection and replacement of internal components in the second cavity component 50, reducing maintenance difficulty and cost. In addition, the design of the fitting groove 61 makes the rear cover 60 fit the second cavity component 50 more closely after installation, improving the overall appearance of the speaker.

[0030] The working principle of this utility model is as follows: When the speaker with terminal 42 is in operation, external audio devices are connected to terminal 42 at the through hole 41 of the first cavity component 40 via wires (not shown in the figure). Depending on the requirements, wires (not shown in the figure) can be inserted into one or both wiring holes 43 on both sides of terminal 42 and fixed, thus establishing circuitry between the external device and the speaker. Audio signals are transmitted to terminal 42 via wires (not shown in the figure), and then from terminal 42 to speaker assembly 30 via wires (not shown in the figure). Speaker assembly 30 receives the electrical signals and converts them into mechanical vibrations, thereby generating sound waves. The sound waves pass through the radially symmetrical arc-shaped perforated structure 21 of the decorative cover 20, propagating outwards for the user to listen to. The perforated structure 21 ensures smooth sound wave propagation and reduces loss. During speaker operation, the radially shaped heat sink 47 at the rear end of the first cavity component 40 quickly conducts the heat generated by internal components (such as the power amplifier module) to the outside, achieving heat dissipation and ensuring stable component operation. Meanwhile, the components work together through precise connection structures: the decorative cover 20 is connected and fixed to the second connection hole 46 of the first cavity component 40 by engaging with the locking bolt (not shown in the figure) through the first connection hole 23; the speaker assembly 30 is positioned by engaging with the first cavity component 40 through the snap-fit ​​ring 31 and the snap-fit ​​groove 45 of the first cavity component 40; the first cavity component 40 is engaged with the positioning groove 51 and the positioning slot 52 of the second cavity component 50 through the positioning ring 48 and the positioning pin 49; the second cavity component 50 is fixed by engaging with the rear cover 60 through the chuck 54 and the fitting groove 61 of the rear cover 60. All connection structures work together to ensure the overall stability of the speaker structure, ensuring that it can still work normally under vibration environment and continuously output stable and high-quality sound.

[0031] 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.
