Description

Technical Field

[0001] This application relates to the field of audio technology, specifically to an audio structure capable of adjusting the sound field. Background Technology

[0002] Traditional indoor audio systems mostly use a fixed installation structure, and the position, height and directivity of the speakers are difficult to adjust after deployment. This design can meet basic needs in conventional scenarios, but it is inconvenient in places where the dynamic adaptability of the sound field is required.

[0003] In multi-functional conference rooms, when the meeting mode is switched to report mode or group discussion mode, the layout of the audience area may change, and the sound field coverage of the fixed sound system cannot be optimized accordingly. This can lead to problems such as insufficient sound pressure level, sound image positioning deviation, or abnormal reverberation time in some areas. In exhibition halls or art spaces, when temporary exhibition areas are adjusted or the location of key exhibits is changed, traditional sound systems cannot quickly reconstruct the sound field focus, resulting in misalignment between the narration audio and the exhibit location, affecting the audience's immersive experience. In open spaces such as atriums of commercial complexes or theater lobbies, traditional fixed sound systems are prone to sound coloration or sound focusing due to the complex reflective surfaces of the building structure. Moreover, equipment maintenance requires the use of a lifting platform, resulting in low operational efficiency. Although some high-end sound systems achieve sound field correction through electronic crossover or digital signal processing (DSP) technology, their essence is still passive compensation, and the effect is limited. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides an acoustic structure that can adjust the sound field, which has the advantages of easy adjustment and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a sound structure capable of adjusting the sound field, comprising two ropes and a set of connectors. The connectors are arranged in a distributed manner on the two ropes. A set of walking mechanisms is provided on the surface of the two ropes. An electric actuator is provided below each walking mechanism. A hinge seat is fixedly connected to the output end of each electric actuator. A pitch axis is rotatably connected between the left and right inner sidewalls of each hinge seat. A connecting plate is fixedly connected to the outer surface of each pitch axis. A mounting bracket is fixedly connected to the bottom of each connecting plate. An angle axis is rotatably connected to the inner bottom wall of each mounting bracket. A sound body is fixedly mounted at the top of each angle axis.

[0006] Furthermore, the walking mechanism includes a walking frame, the top of each electric push rod is fixedly connected to the bottom of the walking frame adjacent to it, guide sleeves are fixedly connected to both sides of the walking frame, each guide sleeve is slidably sleeved with a rope adjacent to it, two power shafts are rotatably connected between the front and rear inner side walls of the walking frame, a set of traction wheels is fixedly connected to the outer surface of each of the two power shafts, each rope is located between its adjacent set of traction wheels, and one end of the power shaft is connected to an external power source.

[0007] With the above scheme, when the power shaft drives the traction wheel to rotate, a controllable frictional force is generated between the traction wheel and the rope. Combined with the limiting effect of the guide sleeve, the walking mechanism can achieve smooth displacement and precise positioning along the rope.

[0008] Furthermore, each of the ropes is a steel wire rope.

[0009] The above-mentioned solutions aim to enhance the coefficient of friction with the traction wheel and improve weather resistance.

[0010] Furthermore, each of the connectors includes a fixing plate, each fixing plate is fixedly connected to two ropes, each fixing plate has a connecting post fixedly connected to its upper surface, each connecting post has a mounting plate fixedly connected to its top, and each mounting plate has a set of mounting holes on its upper surface.

[0011] The above solution, with its mounting holes and mounting plates, facilitates connection to the indoor ceiling. The rope arrangement can be adjusted according to the actual apartment layout, and can accommodate straight, curved, or grid-like rope layouts to achieve customized configuration of sound field coverage.

[0012] Furthermore, a first motor is mounted on one side of each of the hinge seats, and the output end of each first motor is fixedly connected to the pitch axis adjacent to it.

[0013] With the above scheme, the first motor drives the pitch axis to achieve pitch angle adjustment.

[0014] Furthermore, a second motor is installed at the bottom of each mounting bracket, and the output end of each second motor is fixedly connected to the bottom end of the angular axis adjacent to it. The second motor is driven by a stepper motor.

[0015] The above method allows the angle axis to rotate, thus adjusting the orientation angle of the speaker body.

[0016] Furthermore, the electric actuator is fixedly connected to its adjacent walking frame by bolts.

[0017] The above solution facilitates disassembly and equipment maintenance.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] This type of sound structure can adjust the sound field. By moving the walking mechanism on the rope track, the position of the main body of the speaker can be adjusted in the horizontal plane. The coverage range can cover straight lines, arcs or grid layouts. The electric actuator can extend and retract to adjust the height of the speaker to adapt to the sound field projection needs of spaces with different floor heights, such as theaters and exhibition halls. The pitch axis and angle axis control the pitch angle and horizontal orientation of the speaker respectively, ensuring that the sound wave directivity is accurately matched to the audience position, directly optimizing the sound source position and directivity, reducing reflected sound interference from the root, and solving problems such as sound focusing and abnormal reverberation that are difficult to handle by purely electronic means in complex spaces.

[0020] The connectors are fixed to the ceiling via mounting plates, supporting customized rope layouts in straight lines, arcs, and grids to adapt to different building structures. The electric actuators and the walking frame are bolted together for easy disassembly and maintenance, reducing operating costs. This speaker structure significantly improves the accuracy of sound field coverage and scene adaptability through three-dimensional spatial degree of freedom adjustment, modular installation, and active physical control mechanisms, making it particularly suitable for spaces with high requirements for dynamic acoustic performance.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of an adjustable sound field acoustic structure includes two ropes 1 and a set of connectors 2. Each connector 2 includes a fixing plate 201, and each fixing plate 201 is fixedly connected to the two ropes 1. A connecting post 202 is fixedly connected to the upper surface of each fixing plate 201, and a mounting plate 204 is fixedly connected to the top of each connecting post 202. A set of mounting holes 203 are opened on the upper surface of each mounting plate 204. Through the setting of the mounting holes 203 and the mounting plate 204, it is easy to connect to the ceiling of the room. The arrangement of the ropes 1 can be adjusted according to the actual room layout, and can be adapted to straight, arc or grid-shaped rope 1 layouts to achieve customized configuration of sound field coverage.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The connectors 2 are distributed on two ropes 1. A set of walking mechanisms 3 is provided on the surface of the two ropes 1. The walking mechanisms 3 can move on the surface of the ropes 1 by being driven by an internal power source. Each walking mechanism 3 is provided with an electric push rod 4 below it. The electric push rod 4 is fixedly connected to the walking frame 301 next to it by bolts, which can be easily disassembled and the equipment is easy to maintain. The output end of each electric push rod 4 is fixedly connected to a hinge seat 5. The left and right inner sidewalls of each hinge seat 5 are rotatably connected to a pitch axis 6. The outer surface of each pitch axis 6 is fixedly connected to a connecting plate 7. A first motor 11 is installed on one side of each hinge seat 5. The output end of each first motor 11 is fixedly connected to the pitch axis 6 next to it. The first motor 11 drives the pitch axis 6 to realize the pitch angle adjustment.

[0032] Please see Figure 1 , Figure 2 and Figure 3Each connecting plate 7 has a mounting bracket 8 fixedly connected to its bottom. Each mounting bracket 8 has an angle shaft 9 rotatably connected to its inner bottom wall. Each angle shaft 9 has a speaker body 10 fixedly mounted at its top. The angle of the speaker body 10 can be adjusted by setting the pitch axis 6. The height of the speaker body 10 can be adjusted by using the electric push rod 4. The orientation of the speaker body 10 can be raised by using the angle shaft 9. The position of the speaker body 10 area can be adjusted by using the walking mechanism 3. The sound field coverage and directivity can be precisely controlled to adapt to the acoustic optimization needs of different scenarios. Each mounting bracket 8 has a second motor 12 installed at its bottom. The output end of each second motor 12 is fixedly connected to the bottom end of the angle shaft 9 that is close to it. The second motor 12 is driven by a stepper motor, and the angle shaft 9 is rotated to realize the adjustment of the orientation angle of the speaker body 10.

[0033] Please see Figure 1 , Figure 2 and Figure 3 Each rope 1 is a steel wire rope, preferably galvanized and with a spiral anti-slip texture to enhance the coefficient of friction and weather resistance with the traction wheel 304. The walking mechanism 3 includes a walking frame 301. The top of each electric push rod 4 is fixedly connected to the bottom of the adjacent walking frame 301. Guide sleeves 302 are fixedly connected to both sides of the walking frame 301. Each guide sleeve 302 is slidably sleeved with the adjacent rope 1. Two power drives are rotatably connected between the front and rear inner walls of the walking frame 301. A set of traction wheels 304 are fixedly connected to the outer surface of the two power shafts 303. Each rope 1 is located between its adjacent set of traction wheels 304. One end of the power shaft 303 is connected to an external power source, which can be fixed on the walking frame 301. With the above arrangement, when the power shaft 303 drives the traction wheels 304 to rotate, a controllable friction force is generated between the traction wheels 304 and the rope 1. With the limiting effect of the guide sleeve 302, the walking mechanism 3 can achieve smooth displacement and precise positioning along the rope 1.

[0034] It should be noted that the power supply cable must be a flexible shielded cable to prevent the line from breaking when the walking mechanism moves.

[0035] The working principle of the above embodiment is as follows: The power source of the walking mechanism 3 is a motor fixed to the walking frame 301, which drives the power shaft 303 to rotate, thereby driving the traction wheel 304 to rotate. The traction wheel 304 generates friction with the galvanized steel wire rope with anti-slip texture, pushing the walking frame 301 to slide along the rope 1. The guide sleeve 302 sleeved on the rope 1 constrains the trajectory of the walking frame 301, ensuring smooth and accurate horizontal movement. After receiving the command, the electric push rod 4 extends and retracts, driving the lower hinge seat 5 and the speaker body 10 to rise and fall. In the theater scene, the speaker is lowered to the height of the audience seats to enhance the direct sound; in the exhibition hall, it is raised to near the ceiling to expand the coverage area. The first motor 11 on the side of the hinge seat 5 drives the pitch axis 6 to rotate, driving the connecting plate 7 and the speaker body 10 to swing up and down. In the lecture hall, the downward angle is aimed at the audience in the back row to avoid overloading the sound pressure in the front row; in the art exhibition, the upward angle is aimed at the high-hanging exhibits for synchronous explanation. The second motor 12 at the bottom of the mounting frame 8 drives the angle axis 9 to rotate the speaker body 10, so that the main lobe of the sound wave accurately covers the target area.
