Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker array with multi-directional coverage. Background Art

[0002] In order to increase the effective coverage area of ​​the speakers, speaker arrays are used in many large-scale activities. Depending on the usage, the speaker array can be parked on the ground or suspended at a high place. When placed on the ground, the speaker array can be distributed in a linear array. When suspended, the posture of each speaker array needs to be adjusted so that the radiation direction of the suspended speaker array can take into account both near and far.

[0003] For example, a Chinese utility model patent with an authorization announcement date of 2022-6-7 and an authorization announcement number of CN216700233U discloses a main sound reinforcement three-way curved array loudspeaker, which relates to an array loudspeaker technical field, including a main controller, a loudspeaker and a top plate, wherein an auxiliary rod is rotatably installed on the top wall of the main controller, and the other end of the auxiliary rod is rotatably installed on the bottom wall of the slider, and the top of the slider is slidably installed in the slide rail, and the slide rail is installed on the bottom wall of the top plate, and at the same time, a piston cylinder is rotatably installed on the bottom wall of the top plate, and the piston cylinder is arranged away from the slider, and a piston rod is slidably installed inside the piston cylinder, and the protruding end of the piston rod is rotatably installed on the top wall of the main controller, and the slider is driven to move horizontally, driving the auxiliary rod to pull the main controller to shake, so as to adjust the working angle of the equipment, and a fixing plate is installed on the bottom wall of the main controller, wherein a pair of connecting plates are symmetrically installed on the left and right side walls of the loudspeaker, and the connecting plates are connected to the fixing plates through connecting bolts, and a pair of fixing plates are also symmetrically installed on the bottom wall of the loudspeaker.

[0004] However, when the above-mentioned main sound reinforcement three-way curved array loudspeaker is used, when the posture of the loudspeaker array is adjusted, the adjustment of each group of loudspeakers needs to be performed separately. Utility Model Content

[0005] The utility model provides a speaker array with multi-directional coverage, which solves the technical problem that when the main sound reinforcement three-way curved array speaker is used in the prior art, the posture of the speaker array cannot be adjusted synchronously.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A speaker array with multi-directional coverage includes a support frame, a posture adjustment mechanism is provided on the support frame, the posture adjustment frame mechanism includes a fixed plate frame and multiple groups of movable plate frames connected in sequence, the bottom end of the bottommost movable plate frame is rotatably connected to the top of the fixed plate frame, and the adjacent movable plate frames are hinged by a connecting shaft. Speakers are installed on the fixed plate frame and each group of movable plate frames, and the posture adjustment frame mechanism also includes a gear linkage component, which is used to synchronously control the relative posture changes between the multiple groups of movable plate frames. Through the design of the posture adjustment mechanism and the movable plate frame, the coverage of the speaker array in different directions can be achieved, providing a wider sound propagation range. The posture adjustment mechanism can adjust the angle and direction of the speaker array to adapt to different environments and needs. In this way, the projection effect of the sound can be optimized and a better auditory experience can be provided. Through the gear linkage component, synchronous control between the multiple groups of movable plate frames can be achieved to ensure that the overall posture changes of the speaker array are coordinated and consistent. In this way, the uniform distribution and consistency of the sound can be maintained.

[0008] Further, the gear linkage assembly includes a vertical shaft rotatably mounted on the movable plate frame and parallel to the movable plate frame, the length of the vertical shaft is less than the movable spanner, and the upper and lower ends of the vertical shaft are respectively provided with a bevel gear 1 and a bevel gear 2. Except for the topmost group of movable plate frames, the tops of the remaining groups of movable plate frames are fixed with bevel gears 4, and except for the bottommost group of movable plate frames, the bottoms of the remaining groups of movable plate frames are fixed with bevel gears 5. The bevel gear 2 on the bottommost group of movable plate frames is meshed with the bevel gear 3 on the fixed shaft, and the fixed shaft passes through the movable plate frame and is fixedly connected to the fixed plate frame. The bevel gears 2 in the two adjacent groups of movable plate frames are meshed with the bevel gear 4, and the bevel gears 1 in the two adjacent groups of movable plate frames are meshed with the bevel gear 5. Through the meshing of the bevel gears, synchronous control between multiple groups of movable plate frames can be achieved to ensure that their relative posture changes are coordinated and consistent. In this way, the overall balance and stability of the speaker array can be maintained. The design of the bevel gear can provide more precise posture adjustment, so that the angle and direction adjustment of the speaker array is more accurate. In this way, the fine adjustment requirements under different scenarios and needs can be met.

[0009] Furthermore, a motor is installed on the movable plate frame, and the motor is connected to the vertical shaft. A group of motors drives the gear linkage assembly to rotate, thereby synchronously linking multiple groups of movable plate frames to rotate, and quickly adjust the relative postures of multiple groups of movable plate frames to change synchronously, without the need to adjust the postures one by one.

[0010] Furthermore, at the connection of two adjacent groups of movable plate frames, the axle of bevel gear 4, the axle of bevel gear 5, and the connecting shaft are on the same axis. By placing the axle of bevel gear 4 on the bottom group of movable plate frames, the axle of bevel gear 5 on the upper group of movable plate frames, and the connecting shaft between the two adjacent groups of movable plate frames on the same axis, it can be ensured that the transmission effect between them is more stable and accurate. Since the axle and the connecting shaft are on the same axis, the energy loss in the transmission process is small and the transmission efficiency is higher. In this way, the posture adjustment of the speaker array can be ensured to be more flexible and accurate.

[0011] Furthermore, the bevel gears 4 and 5 on the two adjacent groups of movable plate frames are respectively located on both sides of the connecting shaft. The stability of the entire gear linkage assembly can be enhanced by placing the bevel gears 4 and 5 on both sides of the connecting shaft between the two adjacent groups of movable plate frames. This can effectively reduce the swing and shaking during the transmission process, ensuring that the posture adjustment of the speaker array is more stable and reliable. By distributing the bevel gears 4 and 5 on both sides of the connecting shaft, load balancing can be achieved. This can reduce the pressure on one side, extend the service life of the assembly, and maintain the balance of the entire system.

[0012] Furthermore, the bevel gear 1, bevel gear 2, bevel gear 3, bevel gear 4 and bevel gear 5 are all bevel gears of the same specification. Since bevel gears 1 to 5 are all of the same specification, their fit in the transmission system is tighter and more precise. This can reduce friction and clearance in the transmission, improve the efficiency and precision of the transmission, and enhance the reliability and stability of the system.

[0013] Furthermore, the bottom side of the support frame is provided with moving wheels, so that the speaker array can be conveniently moved when parked on the ground, and the speaker array can be distributed in a vertical array.

[0014] Furthermore, a hanging ring is provided on the bottom side of the support frame, and when the speaker array with multi-directional coverage is placed on the ground, the lowest point of the hanging ring is higher than the lowest point of the moving wheel. By providing the hanging ring on the bottom side of the support frame, the speaker array with multi-directional coverage can be conveniently hung at a suitable position. The position of the hanging ring is higher than the lowest point of the moving wheel, ensuring that the normal operation of the moving wheel will not be interfered with when placed on the ground, while ensuring the stable suspension of the speaker array.

[0015] Furthermore, the fixed plate frame and the movable plate frame are respectively connected to the speakers by bolts. By fixing the speakers to the fixed plate frame and the movable plate frame with bolts, the speakers can be firmly fixed at the designated positions. This can prevent the speakers from shaking or loosening during use, and ensure the stability and consistency of the audio output.

[0016] Furthermore, the gear linkage assembly includes a vertically placed rack that moves up and down through a transmission mechanism, and the rack is meshed with a gear at the rear end of the speaker that is fixedly connected to the movable plate frame. Due to the design of the gear linkage assembly, the user can quickly adjust the relative postures between multiple sets of movable plates to change synchronously as needed, and this flexibility makes the speaker suitable for different scenarios and application requirements.

[0017] Beneficial effects of the utility model:

[0018] 1. By installing moving wheels on the bottom side of the support frame, it can be easily moved when parked on the ground, and the speaker array can be distributed in a vertical array;

[0019] 2. When hoisted to a high place, a group of motors can be used to drive the gear linkage assembly to rotate, and then synchronously link multiple groups of movable plate frames to rotate, quickly adjusting the relative posture changes between multiple groups of movable plate frames, and no longer needing to adjust the posture one by one, and the posture can be further adjusted after the hoisting is completed.

[0028] Example 2, as a preferred implementation of a speaker array with multi-directional coverage, Figure 1 , Figure 4 As shown, the difference from Example 1 is that the gear linkage assembly includes a vertical shaft rotatably mounted on the movable plate frame and parallel to the movable plate frame, the length of the vertical shaft is less than the movable spanner, and the upper and lower ends of the vertical shaft are respectively provided with a bevel gear 1 and a bevel gear 2.

The design of the bevel gear can provide more precise posture adjustment, so that the angle and direction adjustment of the speaker array are more accurate. In this way, the fine adjustment requirements under different scenarios and needs can be met.

[0029] Example 3, as a preferred implementation of a speaker array with multi-directional coverage, Figure 2 , Figure 4 As shown, the difference from Example 2 is that a motor is installed on the movable plate frame, and the motor is connected to the vertical shaft. A group of motors drives the gear linkage assembly to rotate, and then synchronously links the rotation of multiple groups of movable plate frames, and quickly adjusts the relative postures of multiple groups of movable plate frames synchronously, and no longer needs to adjust the postures one by one.

[0030] Example 4, as a preferred implementation of a speaker array with multi-directional coverage, Figure 4 As shown, the difference from Example 3 is that at the connection of the two adjacent groups of movable plate frames, the axle of bevel gear 4, the axle of bevel gear 5, and the connecting shaft are on the same axis.

Placing bevel gear four and bevel gear five on both sides of the connecting shaft between the two adjacent groups of movable plate frames can enhance the stability of the entire gear linkage assembly. This can effectively reduce the swing and shaking during the transmission process, ensuring that the posture adjustment of the speaker array is smoother and more reliable. By distributing bevel gear four and bevel gear five on both sides of the connecting shaft, load balancing can be achieved. This can reduce the pressure on one side, extend the service life of the component, and maintain the balance of the entire system.

When the speaker array with multi-directional coverage is placed on the ground, the lowest point of the hanging ring is higher than the lowest point of the moving wheel. By providing a hanging ring on the bottom side of the support frame, the speaker array with multi-directional coverage can be conveniently hung in a suitable position. The position of the hanging ring is higher than the lowest point of the moving wheel, ensuring that the normal operation of the moving wheel will not be interfered with when placed on the ground, while ensuring the stable suspension of the speaker array.
