Description

Technical Field

[0001] The utility model relates to the technical field of sound box bodies, in particular to an angle adjustment structure of a sound box body. Background Art

[0002] The speaker cabinet refers to the outer shell structure used to accommodate the internal components of the speaker and play a protective role. It is usually made of metal, plastic and other materials, and has good sealing and stability to prevent the external environment from interfering with the internal components of the speaker. The key to the speaker cabinet design is its ability to effectively transmit audio signals while maintaining good sound effects. During the design process, the size, shape, material and other factors of the speaker need to be fully considered to achieve the best sound quality and visual effects. In addition, the speaker cabinet must also meet the requirements of easy installation, disassembly and maintenance, so that users can easily operate and maintain the speaker.

[0003] The patent document with application number CN202220996703.4 discloses a speaker box and a speaker, which includes: a front shell, a connecting column is provided in the front shell, and the connecting column is provided with a through hole running through the upper and lower ends thereof; a rear shell, which is matched with the front shell, and the rear shell is provided with supports and studs which are arranged one by one and connected from the bottom wall toward the top opening thereof, and the studs are provided with threaded holes; a screw, the threaded end of which passes through the through hole and is screwed together with the threaded hole to connect the front shell and the rear shell together. It can make the stud shorter to avoid the stud being too long and easy to bend or even break. At the same time, the setting of the support can also enhance the structural strength of the stud, making the stud less likely to bend or break, so that the stud and the screw can be reliably connected together, and then the front shell and the rear shell can be reliably connected together. In addition, because the stud can be made shorter, the inlay pins on the mold used to form the rear shell can be made shorter to avoid deformation and breakage of the inlay pins, thereby reducing the difficulty of forming the rear shell and improving production efficiency. Based on the search of the above-mentioned patents and combined with the speaker cabinet in the prior art, it is found that the speaker cabinet cannot quickly adjust the position and effect of the speaker in the speaker cabinet when it is used, especially the large speaker cannot effectively adjust the direction and angle effect. The large speaker is heavy, but it is difficult to rotate the large speaker, and the operation is complicated, time-consuming and labor-intensive. Utility Model Content
