Description

Technical Field

[0001] The utility model relates to the technical field of audio equipment accessories, and more specifically, to an audio equipment shell. Background Art

[0002] In the prior art, the design of audio device housings faces multiple challenges, which may limit the efficiency and convenience of the devices in practical applications.

[0003] Firstly, the existing audio device housings usually adopt a relatively simple structure. Although this helps to reduce manufacturing costs, it also leads to limitations in its mobility. In large audio equipment such as professional audio systems, this structural design makes it a challenge to move the device, especially without appropriate mobility aids, as users may find it inconvenient to operate.

[0004] Secondly, although the prior art has adopted a design with movable wheels to improve the mobility of audio equipment, these movable wheels are often of uneven quality and easily damaged. In addition, the installation and disassembly process of the movable wheels is usually complicated, and there is no convenient mechanism to quickly replace damaged wheels. This is particularly disadvantageous in an environment where the equipment needs to be moved frequently. For example, in concerts or public speeches, audio equipment needs to be frequently moved and adjusted. The complicated wheel replacement process may cause delays in use and affect the overall performance or performance.

[0005] In addition, when existing audio devices use external devices such as microphones, the cable fixing method usually adopted is relatively simple. This simple fixing method can easily cause the cable to loosen or fall off during use, especially when the external device needs to be located at a remote location or moved frequently. The instability of the cable will seriously affect the stability of the sound quality and the reliability of use. The looseness of the cable may not only interrupt the audio signal, but also cause physical damage to the connection port of the device. Utility Model Content
