[0002] Previous product defects

[0003] 1. Limited functionality:

[0004] Most products and devices on the market that utilize similar functions are simply combinations of single-function light boxes and single-function speaker products. They often excessively emphasize the unique characteristics of the speaker products, typically involving broad but shallow control functions. For example, some focus solely on a single speaker, emphasizing only high sound pressure level, high power, and strong directivity. This promotes the product's single, powerful functionalities while downplaying the complementary and coordinating functions that the product should possess in various application scenarios.

[0005] 2. The product lacks system expansion capabilities:

[0006] To date, in the audio amplification product application market, the use of relatively independent product devices to build application systems is still prevalent. The numerous functions of these products fail to meet the system application needs of the market. Their unsystematic connection methods and misleading positioning have largely hindered the progress of audio product development and the construction of system application technologies.

[0007] 3. Incompatibility:

[0008] During sound transmission, if the transmission characteristics of a product device with independent control functions cannot be well integrated into the audio transmission, its incompatibility will cause significant distortion in the sound transmission, severely affecting the comprehensive sound indicators such as clarity, intelligibility, and fidelity.
