[0036] An embodiment of the present invention provides an intelligent adaptive sound field matrix sound column. Refer to Figure 1 and Figure 2 , including:

[0037] A sound column main body 11;

[0038] A number of speaker modules 12, installed on the sound column main body 11, and a number of the speaker modules 12 are sequentially connected by relative rotation;

[0039] Adjacent two of the speaker modules 12 are rotationally connected by a connection component, and adjacent two speaker modules 12 are electrically connected through a conductive machine 23.

[0040] In this embodiment, the speaker modules 12 on the sound column body 11 are relatively rotatably connected through a connecting component, and the angles of each speaker module 12 can be flexibly adjusted according to the actual use environment and requirements, so as to achieve precise control of the sound field coverage range. At the same time, it solves the problem of uneven sound coverage in the sound column 1 speakers with traditional fixed-angle speaker arrangements in scenarios with 360° sound field coverage requirements such as large exhibition halls, outdoor squares, and multi-functional halls. By adjusting the angles of the speaker modules 12, it can ensure that the sound is evenly distributed throughout the space, avoiding the phenomenon of sound dead spots or overly strong sound in certain areas, and improving the listening experience of the audience. Specifically, the connecting component can be set according to actual production requirements, such as using a precision gear or a worm and worm gear structure to achieve precise angle adjustment and maintenance. Specifically, meshing gears or worm and worm gear structures can be respectively arranged on the contact surfaces between two adjacent speaker modules 12. By rotating the speaker module 12, the two adjacent speaker modules 12 are rotationally connected through the meshing between the gears or worm and worm gear, realizing arbitrary angle adjustment of the speaker module 12.

[0041] Furthermore, the adjacent speaker modules 12 are electrically connected through a conductive machine 23, ensuring the stability and efficiency of signal transmission and avoiding the problem of poor electrical contact caused by rotational connection. Specifically, according to actual use requirements, a connection method of connecting a power line and a signal line can be adopted, or a contact conductive connection method can also be adopted. There is no limitation here, as long as the electrical connection between adjacent speaker modules 12 can be achieved.

[0042] In this embodiment, the speaker module 12 adopts a modular connection and design structure, making the repair or replacement of a single speaker module 12 simple. At the same time, it can also adapt to different acoustic requirements by increasing or decreasing the speaker modules 12, improving the scalability and service life of the product.

[0043] Furthermore, the connecting component is set as a magnetic attachment, and the magnetic attachments are arranged along the rotation direction of the speaker module 12.

[0044] In this embodiment, the connecting component adopts a magnetic attachment, greatly simplifying the design of the connecting component, reducing the number of mechanical parts, and lowering the manufacturing and maintenance costs. The magnetic connection can provide stable rotational support and reduce performance degradation caused by mechanical wear or loosening. The magnetic attachment allows the speaker module 12 to be finely adjusted within a range of 360°, thereby more precisely controlling the sound field coverage range. At the same time, the installation and disassembly of the speaker module 12 become simple and fast, facilitating maintenance and upgrading. Specifically, the magnetic attachment can adopt the adsorption method of magnet and magnet, or the adsorption method of magnet and magnetic material. There is no limitation here.

[0045] Specifically, referring to Figure 3 andFigure 4 In this embodiment, the magnetic attachment is set as the annular magnet 121, and the annular magnet 121 is installed on the contact surface between every two adjacent horn modules 12.

[0046] In this embodiment, on the contact surface between adjacent horns, an annular magnet 121 is installed. The relative rotation between two adjacent horn modules 12 can move along the circumferential direction of the annular magnet 121, so that 360° rotation of the horn module 12 can be realized, and it can also ensure that adjacent horn modules 12 can be stably adsorbed and maintain a certain degree of rotational freedom. By respectively arranging the annular magnet 121 on the contact surface of the horn module 12, there is no need to make too many modifications to the structure of the horn module 12, and only an installation groove for installing the annular magnet 121 needs to be set. The product structure design is simpler and the cost is low.

[0047] Or, Figure 5 and Figure 6 the magnetic attachment is set as the annular magnet 121, the surface of the horn module 12 is made of a magnetic material adsorbed to the annular magnet 121, and the annular magnet 121 is installed on the contact surface of one of every two adjacent horn modules 12.

[0048] In this embodiment, compared with the structure of the previous embodiment, the contact surface of the horn module 12 can be made of a material capable of adsorbing to the magnet. Specifically, the housing of the horn module 12 can be made of a material with magnetic adsorption properties. For example, the housing of the horn module 12 is made of an iron shell. In this way, between two adjacent horn modules 12, only by installing the annular magnet 121 on the contact surface of one of the horn modules 12 can the relative rotation between the two adjacent horn modules 12 be completed. At the same time, its rotation is arranged along the circumferential direction of the annular magnet 121 and rotates 360°. This kind of structure can improve the structural stability of the horn module 12 while realizing the relative rotation between two adjacent horn modules 12, and the structure design is simple.

[0049] In the above two embodiments, the structure of using the annular magnet 121 can enhance the connection stability between the horn modules 12 and reduce the performance degradation caused by mechanical wear or loosening. By designing the magnetism and size of the annular magnet 121, precise control of the rotation angle of the horn module 12 can be realized, thereby improving the accuracy and uniformity of sound field coverage. The installation and maintenance of the annular magnet 121 are simpler than the existing mechanical structure rotation connection method. It only needs to ensure that the magnetism and position of the magnet are correct, without a complex debugging process, and the manufacturing and use costs are lower.

[0050] Furthermore, referring to Figure 3 and Figure 4, the conductive mechanism 23 includes a conductive ring 122 and a conductive probe 123. The conductive probe 123 is slidably connected to the conductive ring 122 along the rotation direction of the horn module 12. The conductive ring 122 and the conductive probe 123 are respectively arranged on the contact surfaces of two adjacent horn modules 12.

[0051] In this embodiment, the conductive structure between two adjacent horn modules 12 adopts a sliding connection structure of a conductive ring 122 and a conductive probe 123. The conductive ring 122 can be a circular ring or an annular belt made of a conductive material (such as copper, silver, or a gold-plated alloy). Its width and thickness are determined according to the current demand and space limitation. The conductive ring 122 is fixed on the contact surface of the horn module 12 to ensure that it will not fall off or move during rotation. Corresponding to the conductive ring 122, a conductive probe 123 is arranged on the contact surface of the adjacent horn module 12. The conductive probe 123 is an elongated rod-shaped structure made of a conductive material. One end of it is connected to the circuit inside the horn module 12, and the other end is designed to be able to make sliding contact with the conductive ring 122. The number and position of the conductive probes 123 are determined according to the design of the conductive ring 122 to ensure good electrical contact during rotation. In this embodiment, the conductive probes 123 and the conductive ring 122 are respectively set to three, including a power supply positive electrode, a power supply negative electrode, and a signal terminal in sequence, ensuring normal electrical conduction and signal conduction between the horn modules 12.

[0052] The sliding connection design of the conductive ring 122 and the conductive probe 123 ensures stable electrical contact between adjacent horn modules 12 during rotation, avoiding signal interruption or sound quality degradation caused by poor contact. At the same time, the horn module 12 can rotate arbitrarily within 360°, improving the flexibility and adaptability of the sound column 1 so that it can better adapt to different sound field requirements.

[0053] Furthermore, referring to Figure 5 and Figure 6 , the conductive mechanism 23 includes a conductive ring 122 and an elastic conductive ring 124. A plurality of conductive bumps 125 are arranged on the elastic conductive ring 124. The plurality of conductive bumps 125 are arranged along the rotation direction of the horn module 12, and the plurality of conductive bumps 125 are slidably connected to the conductive ring 122 along the rotation direction of the horn module 12; the conductive ring 122 and the elastic conductive ring 124 are respectively arranged on the contact surfaces of two adjacent horn modules 12.

[0054] In this embodiment, compared with the previous embodiment, one of the conductive rings 122 is changed to a plurality of conductive bumps 125 uniformly arranged along the axial direction of the elastic conductive ring 124. In this way, in the previous embodiment, the point contact between each conductive ring 122 and the conductive probe 123 is changed to a multi-point contact between each conductive ring 122 and a plurality of conductive bumps 125. Since the elastic conductive ring 124 has a certain elasticity, the conductive bumps 125 can maintain a good contact pressure on the conductive ring 122, thereby ensuring the stable transmission of electricity and signals. At the same time, the elastic design of the elastic conductive ring 124 can also adapt to the change of contact pressure at different angles, further improving the durability of the system. The design of the conductive bumps 125 can also reduce the friction and wear between the conductive ring 122, and extend the service life of the conductive mechanism 23.

[0055] Furthermore, a positioning mechanism is further provided between two adjacent horn modules 12. The positioning mechanism includes a positioning groove 126 and an elastic positioning member 127 that are engaged with each other. The positioning groove 126 and the elastic positioning member 127 are respectively provided on the contact surfaces of two adjacent horn modules 12.

[0056] In this embodiment, by setting the positioning mechanism, two adjacent horn modules 12 can be accurately positioned. When the sound column 1 is not in use, the horn module 12 can be quickly reset, so that the horn module 12 is effectively positioned at the initial position, preventing the horn module 12 from rotating and causing collision and wear, and ensuring its service life. Specifically, between two adjacent horn modules 12, a positioning groove 126 is provided on the surface of one of the horn modules 12, and an elastic positioning member 127 corresponding to the positioning groove 126 is provided on the surface of the other horn module 12. One end of the elastic positioning member 127 is fixed on the contact surface of the horn module 12, and the other end can be elastically engaged into the positioning groove 126. When two adjacent horn modules 12 rotate relative to each other and approach the preset position, the elastic positioning member 127 will automatically snap into the positioning groove 126 to achieve precise positioning. Specifically, referring to Figure 7 , the elastic positioning member 127 includes a housing 1271. A spring 1272 is installed in the housing 1271. One end of the spring 1272 abuts against the inside of the housing 1271, and the other end is connected to a positioning ball 1273. The positioning ball 1273 protrudes from the surface of the horn module 12 and abuts against the surface of the adjacent other horn module 12. When the positioning ball 1273 moves to the positioning groove 126, the positioning ball 1273 snaps into the positioning groove 126 to complete the positioning between two adjacent horn modules 12. At the same time, the structure of the positioning ball 1273 can reduce the friction force with the surface of the horn module 12, facilitating the angle adjustment of the horn module 12.

[0057] An embodiment of the present invention also proposes an intelligent speaker 2, referring to Figure 8 and Figure 9, including a speaker main body, the speaker main body is provided with a connecting rod 22 connected to any one of the above-mentioned sound columns 1, the sound column main body 11 and several speaker modules 12 are coaxially provided with connecting holes, and the connecting rod 22 is inserted through the connecting holes.

[0058] In this embodiment, a connecting rod 22 is connected to the speaker main body, and the sound column 1 is integrally connected to the speaker main body through the connecting rod 22, so that an integral body is formed between the sound column 1 and the speaker main body, which is convenient for users to use. Specifically, connecting holes can be coaxially opened on the sound column main body 11 and each speaker module 12, and the connecting rod 22 is inserted into the connecting holes to complete the connection between the connecting rod 22 and the sound column 1. The connection structure is simple and the operation is convenient. At the same time, the stability of the overall structure of the speaker module 12 can be ensured, and the speaker module 12 can be prevented from falling off due to external force. At the same time, users can stack speaker modules 12 at the end of the sound column 1 according to actual use requirements. The speaker modules 12 are connected through a connecting component and a conductive structure, which greatly improves the expansion performance of the sound column 1.

[0059] Furthermore, the speaker main body is provided with a first accommodating groove 21 for accommodating the sound column 1, and a lifting driving mechanism is arranged in the first accommodating groove 21, and the driving end of the lifting driving mechanism is connected to the connecting rod 22.

[0060] In this embodiment, a first accommodating groove 21 for accommodating the sound column 1 is arranged on the speaker main body. The shape and size of the first accommodating groove 21 match those of the sound column 1 to ensure that the sound column 1 can be stably placed therein. At the same time, the opening direction of the first accommodating groove 21 can be designed according to actual needs, so that users can easily install and disassemble the sound column 1. Furthermore, a lifting driving mechanism is arranged in the first accommodating groove 21 for driving the sound column 1 to perform lifting movement inside the speaker main body to complete the automatic storage and lifting of the sound column 1. Refer to Figure 9 , the lifting driving mechanism includes a motor 23 and a lead screw 24 connected to the driving end of the motor 23. A threaded groove is axially opened in the connecting rod 22 to be connected to the lead screw 24. When the motor 23 is started, the lead screw 24 is driven to rotate, and the connecting rod 22 threadedly connected to the lead screw 24 will perform reciprocating movement along the circumference of the lead screw 24, thereby driving the sound column 1 to achieve storage and lifting.

[0061] In this embodiment, by adding a lifting driving mechanism, the smart speaker 2 can adjust the height and angle of the sound column 1 according to actual needs, thereby optimizing the sound field distribution and sound quality performance, improving the flexibility and adaptability of the smart speaker 2, and enabling it to better adapt to different usage environments and user needs.

[0062] Furthermore, the lifting drive mechanism in this embodiment can also be set as a multi-stage lifting structure in the prior art. Taking the three-stage lifting as an example, it includes a motor 23, a housing, a first telescopic section, a second telescopic section, and a third telescopic section. The first telescopic section, the second telescopic section, and the third telescopic section are nested and stored in the housing in sequence. When it is necessary to lift the sound column 1, the motor 23 is started to drive the first telescopic section, the second telescopic section, and the third telescopic section to expand, thereby lifting the sound column 1.

[0063] Furthermore, the speaker main body is provided with a second accommodation groove 25 for accommodating the speaker module 12. In this embodiment, a spare speaker module 12 can be stored in the second accommodation groove 25. When the number of the original speaker modules 12 of the sound column 1 does not meet the user's usage requirements, the user can take out the spare speaker module 12 from the second accommodation groove 25 and quickly expand and install it on the sound column 1, greatly improving the convenience of use. Specifically, in the initial state of the sound column 1, the number of the speaker modules 12 thereon can be set to five, and a certain number of speaker modules 12 can be selected and stored in the second accommodation groove 25 according to actual needs to facilitate the expansion of the sound column 1 by the user.

[0064] Furthermore, the connecting rod 22 is set as a telescopic rod structure, which is convenient for extending the connecting rod 22 when the speaker module 12 is expanded, so that more speaker modules 12 can be adaptively installed, thereby ensuring the improvement of the overall structural stability while the speaker module 12 is expanded. Specifically, in this embodiment, the telescopic rod structure can be composed of an inner sleeve and an outer sleeve. The inner sleeve can slide freely in the outer sleeve and is fixed by a locking mechanism. The locking mechanism can be a knob, a button, or other forms of locking devices for locking the position of the telescopic rod after adjusting the height.

[0065] The above are only the optional embodiments of the present invention, and thus do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
