Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The purpose of this invention is to provide a conversion box to solve the problem that some types of spliced ​​speakers lack diverse installation interfaces due to their own connection structure limitations. By using an adapter, the speaker can be equipped with functions such as hanging, support, and enhanced connection.

[0017] This utility model achieves the above objectives through the following technical solutions: A converter box (1) is used to connect to a speaker (11) and provide a connection interface, including a box body (2), the box body (2) having a first side (3) and a second side (4) arranged opposite to each other; the first side (3) of the box body (2) is provided with a first connection structure (5), the first connection structure (5) includes two pins (7), the two pins (7) are symmetrically fixed on the first side (3) of the box body (2) for connecting to a slot (12) on the speaker (11); the second side (4) of the box body (2) is provided with a second connection structure (6), the second connection structure (6) includes two hanging ring holes (8), at least two connection holes (9) and a through hole (10) through the box body (2), the two hanging ring holes (8) are symmetrically arranged on the second side (4) of the box body (2), and the at least two connection holes (9) are arranged in a straight line between the two hanging ring holes (8).

[0018] According to the above technical solution, the beneficial effects of this utility model are as follows: by setting a conversion box (1) as an intermediary between the speaker (11) and the external connector, the pin (7) on the first side (3) of the conversion box (1) is used to connect with the original slot (12) of the speaker (11), and the second side (4) provides additional hanging ring holes (8), connecting holes (9) and through holes (10), thus successfully expanding the connection method of the speaker (11) whose original functional interface was limited, enabling it to easily realize functions such as hanging, rod support and reinforced connection. This design does not require modification of the speaker (11) body, has good compatibility and versatility, and greatly improves the installation flexibility and application range of the existing pin-slot splicing speaker.

[0019] According to one embodiment of the present invention, the conversion box (1) is structurally based on a box body (2) forming the core part, with its first side (3) and second side (4) facing the speaker (11) and the external environment, respectively. On the first side (3) that docks with the speaker (11), a first connecting structure (5) is provided, which includes two symmetrically arranged pins (7). The shape, size, and spacing of these pins (7) are designed to precisely match the slots (12) on the wall of the target speaker (11), so that when the conversion box (1) approaches the speaker (11), the pins (7) can be smoothly inserted into the slots (12). This cooperation between the pins (7) and the slots (12) provides initial positioning and basic connection support between the conversion box (1) and the speaker (11). On the second side (4) that contacts the external environment, a second connecting structure (6) is provided, which is an area integrating multiple functional interfaces. This includes two hanging ring holes (8), which are symmetrically distributed on the second surface (4), for example, on the left and right sides or the top and bottom sides of the second surface (4). These hanging ring holes (8) are specifically designed for connecting hanging components. Between the two hanging ring holes (8), there are at least two connecting holes (9) arranged in a straight line. These connecting holes (9) are used to connect the rods or other fixing devices supporting the speaker cabinet (11). In addition, a through hole (10) is provided on the second surface (4), which penetrates the housing (2). The main function of the through hole (10) is to provide a channel that allows the user to pass a fastener, such as a screw or bolt, through the conversion box (1) and screw it into the pre-reserved fastening hole on the speaker cabinet (11), thereby providing additional mechanical locking and reinforcement between the conversion box (1) and the speaker cabinet (11), enhancing the stability and load-bearing capacity of the entire connection.

[0020] For example, in one specific embodiment, the housing (2) can be a box-shaped structure made of high-strength metal (such as steel or aluminum alloy) by stamping, bending or casting. The first surface (3) is a plane of the housing (2), on which two cylindrical pins (7) are firmly fixed, the spacing and diameter of which conform to the specifications of the speaker (11) slot (12). The second surface (4) is another plane parallel to the first surface (3). On the second surface (4), two hanging ring holes (8) are symmetrically arranged near the edge, and in the central area between them, a connecting hole (9) and a through hole (10) are arranged along a horizontal or vertical straight line. When it is necessary to install the speaker (11), firstly align the first surface (3) of the conversion box (1) with the side wall of the speaker (11), and insert the pins (7) into the slot (12) of the speaker (11) to complete the positioning. Then, insert a bolt (15) through the through hole (10) on the second side (4) of the adapter box (1) and screw it into the threaded hole on the speaker box (11) or fix it with the nut on the back, thereby firmly locking the adapter box (1) onto the speaker box (11). At this time, the adapter box (1) provides a new interface surface for the speaker box (11) with a hanging eye hole (8) and a connection hole (9). If hanging is required, screw in a hanging eye screw (13) or other hanging parts into the hanging eye hole (8); if support is required, screw in a support rod (14) with a threaded joint into the connection hole (9).

[0021] Please see Figures 1 to 6 In another implementation of the conversion box (1), the structural principle is to further define the connection method between the pin (7) and the box body (2). The pin (7) is welded to the box body (2). Welding is a process that uses heating or pressure to melt or semi-melt metal, thereby forming a strong and permanent connection. By welding the pin (7) to the first surface (3) of the box body (2), it is ensured that the root of the pin (7) and the material of the box body (2) form a metallurgical bond. This connection method has extremely high strength and rigidity, and can effectively resist the shear force, bending moment and pull-out force from the speaker (11). Even when the speaker (11) bears a large weight or is subjected to external impact or vibration, the welded connection can ensure that the pin (7) will not loosen, deform or even break, thereby maintaining the overall stability and safety of the connection between the conversion box (1) and the speaker (11). Its beneficial effect is that it significantly improves the reliability and load-bearing capacity of the pin (7) connection and extends the service life of the product.

[0022] For example, in one specific embodiment, the pin (7) can be a solid metal rod, one end of which is inserted into a pre-drilled hole on the first surface (3) of the box body (2), or placed directly on the surface of the first surface (3). Then, a suitable welding process such as arc welding, laser welding, or resistance welding is used to form a continuous weld at the connection area between the root of the pin (7) and the box body (2), fusing the two together. After welding, the weld can be inspected and necessary post-processing (such as grinding and spraying) can be performed to ensure the quality and appearance of the weld. Through this welding method, the pin (7) is firmly integrated into the structure of the box body (2) into a whole, which can withstand loads far exceeding those of other connection methods (such as bolts and riveting).

[0023] Please see Figures 1 to 6 In another implementation of the conversion box (1), the structural principle is to further define the layout of various functional holes on the second surface (4). The hanging ring hole (8), the connecting hole (9), and the through hole (10) are arranged in a row. This means that these three types of holes are all located on the same imaginary straight line on the second surface (4) of the box body (2). This linear arrangement brings structural simplicity and functional convenience. By concentrating all the main connection and fastening interfaces on a straight line, it is easier for users to find and distinguish the different interface functions when using the box. At the same time, when the hanging parts (13), support rods (14), or fasteners (15) are connected to these holes, their center of force also falls roughly on this line, which helps to make the load distribution more uniform, especially when supported by the connecting hole (9) or suspended by the hanging ring hole (8), which can reduce the eccentric load on the connection interface between the box body (2) and the speaker (11) and reduce the risk of structural deformation or damage. Its beneficial effect is that it optimizes the interface layout and improves the ease of operation and the rationality of the stress structure.

[0024] For example, in one specific embodiment, the second surface (4) of the box body (2) is a rectangular plane. The hanging ring holes (8) are located near both ends of the long side, the connecting holes (9) (e.g., three) and the through hole (10) are located in the central area of ​​the long side, and all five holes (two hanging ring holes, three connecting holes, and one through hole) are on a straight line parallel to the long side. Users can choose to use the hanging ring holes (8) on the left and right sides, the connecting holes (9) in the middle, or the through hole (10) according to installation needs. All these interfaces are on a line, making the connection operation intuitive, and structurally, this straight line can serve as the main load-bearing line, which helps the stability of the structure.

[0025] Please see Figures 1 to 6In another implementation of the conversion box (1), the structural principle is to further define the nature of the main functional holes on the second surface (4). The hanging ring hole (8), the connecting hole (9), and the through hole (10) are all threaded holes. This means that the inner walls of these holes are machined with continuous spiral patterns. This threaded structure allows for direct and secure connection with external components with corresponding external threads. For example, the thread of the hanging ring hole (8) can be matched with a lifting ring or lug (13) with a threaded rod; the thread of the connecting hole (9) can be matched with a support rod (14) with a threaded joint; and the thread of the through hole (10) can be matched with a bolt (15). With the threaded hole design, the user only needs to screw the threaded connector into the corresponding threaded hole to complete the connection without the need for additional nuts or other fasteners (unless further tightening is required), which greatly simplifies the installation process and reduces the types and number of parts required. Meanwhile, the threaded connection itself has high connection strength and vibration resistance. In particular, if the through hole (10) is a threaded hole and forms a threaded engagement with the screw (15) screwed into the speaker (11), it will provide additional reliability for the fastening connection between the conversion box (1) and the speaker (11). Its beneficial effect is that it realizes a convenient, fast and reliable connection between the conversion box (1) and the external connector, reducing installation time and parts costs.

[0026] For example, in one specific embodiment, the eyelet hole (8), connecting hole (9), and through hole (10) all use standard metric threads, such as M8 or M10. These threaded holes can be formed on the inner wall of the housing (2) by tapping. Users can conveniently purchase various eyelet screws (13), support rod adapters (14), or high-strength bolts (15) with M8 or M10 external threads from the market as needed. When it is necessary to hang the speaker (11), the eyelet screw (13) with M8 or M10 threads is directly screwed into the eyelet hole (8) and tightened. When it is necessary to support the speaker (11), the support rod (14) with M8 or M10 threaded connector is screwed into the connecting hole (9). When it is necessary to strengthen the connection between the converter box (1) and the speaker (11), select a bolt (15) that matches the corresponding hole of the through hole (10) and the speaker (11), and screw it into the threaded hole of the speaker (11) through the through hole (10) or screw it out of the speaker (11) and fix it with a nut. This standardized threaded interface design makes the entire system highly compatible.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
