[0004] The technical solution disclosed in the above utility model has a simple and feasible structure, a unique 12-grid ultra-thin design, simple installation, can be mounted on the wall or installed into the wall, does not take up space, and has the characteristics of high power, high sound pressure and wide directivity, and has a significant stereo surround sound effect.

[0005] The above-mentioned ultra-thin multi-grid array loudspeaker cannot be converted between linear and circumferential arrays according to the usage scenario, and its applicable scenarios are limited. Utility Model Content

[0006] The utility model provides an array-type speaker radiation angle adjustment device, which solves the technical problem in the prior art that the speaker array mode cannot be converted according to the usage scenario.

[0007] The technical solution adopted by the utility model is as follows:

[0008] An array-type speaker radiation angle adjustment device includes a vertical frame, a ring seat is provided on the vertical frame, a speaker is installed on the ring seat, and a conversion regulator for adjusting the rotation angle of the ring seat is provided on the vertical frame. The array state of multiple groups of speakers is regulated so that the multiple groups of speakers can be converted between linear, arc, and circumferential arrays. Compared with the current fixed array method, the array form of this solution is more flexible and has a wider range of applications.

[0009] Furthermore, a fan-shaped notch is provided on the outer wall of the vertical frame along the length direction, and the conversion regulator includes an arc-shaped plate slidably arranged in the fan-shaped notch, an oblique groove is provided on the outer wall of the arc-shaped plate, and a protrusion is provided on the inner wall of each group of the annular seats. When the arc-shaped plate slides over each group of annular seats in turn along the fan-shaped notch, the protrusion slides into the oblique groove in turn.

[0010] By adjusting the conversion regulator, the array state of multiple groups of speakers can be converted between linear, arc, and circumferential, making the array form more flexible and applicable to a wider range. The design of the arc plate and the annular seat in the conversion regulator allows the rotation angle of the speaker to be accurately adjusted to meet the sound requirements of different scenes and needs. The coordination of the protrusion and the inclined groove can ensure the stability of the conversion regulator during the rotation process to avoid accidental rotation caused by vibration or external force. The outer rotating sleeve of the vertical frame is provided with an annular seat, and the speaker can be easily installed on the annular seat, reducing the complexity and time cost of installation.

[0011] Furthermore, an outer cylinder is provided outside the vertical frame, and the outer cylinder is located below the annular seat and is slidably connected to the arc plate. As a supporting structure, the outer cylinder can increase the stability and bearing capacity of the entire device, ensuring that the device will not shake or tilt during use. Through the sliding connection between the outer cylinder and the arc plate, the angle can be easily adjusted. The user only needs to gently push or pull the outer cylinder to adjust the angle of the speaker array, which is simple and convenient to operate.

[0012] Furthermore, a top cover is provided on the top of the vertical frame, a telescopic rod is installed on the top cover, the telescopic end of the telescopic rod extends out of the top cover, and the other end of the telescopic rod is fixedly connected to the arc plate. Through the design of the telescopic rod, the user can freely adjust the height of the speaker according to actual needs. Whether it is used in different scenarios or to meet the needs of different listeners, the height of the speaker can be flexibly adjusted through the telescopic rod to obtain the best sound effect. The telescopic end of the telescopic rod extends out of the top cover, which can effectively utilize the space, so that the entire device can be folded up or adjusted to a lower height when not in use, thereby saving space and facilitating storage and carrying.

[0013] Furthermore, a limiter is provided on the vertical frame, and the limiter extends from the vertical frame to limit the protrusion when the arc plate is away from the corresponding annular seat. By setting the limiter, it can be ensured that the arc plate will not exceed a certain range when it is away from the corresponding annular seat, so as to avoid excessive extension or damage to the device. The function of the limiter is to limit the range of motion of the arc plate, ensure that it always maintains proper contact with the corresponding annular seat, thereby enhancing the stability of the device.

[0014] Furthermore, the stopper is located at the fan-shaped notch on the vertical frame. The stopper is located at the fan-shaped notch on the vertical frame, which can provide a more accurate limit position. The shape of the fan-shaped notch can match the structure of the stopper, so that the stopper can accurately limit the position with the protrusion of the arc plate when extending, ensuring that the position of the device is within the correct range.

[0015] Furthermore, a mounting groove is provided on the vertical frame, and the limiter includes a support spring placed in the mounting groove and a limit block sliding in the mounting groove and connected to the support spring, and the limit block extends from the mounting groove under the push of the support spring to contact the protrusion on the annular seat after the arc plate moves away. Through the combination of the mounting groove and the limit block, the limiter can provide precise limit control. When the arc plate moves away, the support spring pushes the limit block to extend from the mounting groove so that it contacts the protrusion on the annular seat, thereby limiting the range of motion of the arc plate. This design can ensure that the device stops at the correct position and provide accurate limit control. The presence of the support spring can provide a certain buffering effect to reduce the impact force when the limit block contacts the protrusion. This buffering effect can protect the structural integrity of the device and reduce the risk of damage caused by sudden impact. At the same time, the spring can also provide a certain protection, so that the limiter can rebound and return to a normal working state when subjected to external force.

[0016] Furthermore, the end of the limit block extending out of the mounting slot is an outwardly convex arc structure. The outwardly convex arc structure enables the limit block to cover a larger range when extended. By adjusting the radius and angle of the outwardly convex arc, different limit ranges can be achieved to meet different work requirements.

[0017] Furthermore, a magnet block is embedded in the contact end between the limit block and the protrusion, and the protrusion is a ferromagnetic block. The introduction of the magnet block can improve the accuracy of the limit. The magnetic attraction can make the alignment between the limit block and the protrusion more accurate, reducing errors and deviations. This helps to ensure that the device stops at the correct position and provides more accurate limit control.

[0018] Furthermore, the vertical frame is provided with a guide groove, the upper part of the guide groove is parallel to the axis of the vertical frame, the lower part of the guide groove spirally rises around the vertical frame, and the speaker is slidably connected to the guide groove. The provision of the guide groove can ensure the stable guidance of the speaker on the vertical frame. The upper part of the guide groove is parallel to the axis of the vertical frame, providing a stable guide plane so that the speaker maintains the correct position in the vertical direction. The lower part of the guide groove spirally rises around the vertical frame, increasing the contact area of ​​the guide and further improving the stability of the guide.

At the same time, the limiter 8 is located at the fan-shaped notch 11 on the vertical frame 1, that is, the mounting groove 12 is provided at the fan-shaped notch 11 on the vertical frame 1. The limiter 8 includes a support spring 81 arranged in the mounting groove 12 and a limit block 82 sliding in the mounting groove 12 and connected to the support spring 81. After the arc plate 41 moves away, the limit block 82 extends from the mounting groove 12 under the push of the support spring 81 and contacts the protrusion 43 on the annular seat 2, thereby limiting the protrusion 43 to prevent the speaker 3 in the vertical arrangement state from moving. At the same time, the end of the limit block 82 extending out of the mounting groove 12 is an outward convex arc structure. The setting of the outward convex arc structure facilitates the arc plate 41 to squeeze the limit block 82 into the mounting groove 12 when it moves closer.
