The line array​ speaker system has been widely developed and applied at home and abroad in recent years, and it appears in large-scale sports games and large-scale performances with its unique advantages. It can almost be said that no speaker manufacturing company does not produce line array speakers.

The development basis of the line array speaker system is the development of theoretical research and the progress of manufacturing technology. The requirements for the sound reinforcement function and the promotion of the market are the driving force for the development of line array speakers.

The sound reinforcement system is a system that amplifies the voice of the performer in real-time and transmits it to the listener. Performers and listeners are usually in the same acoustic environment. Line Array must meet the needs of users during the design process, and design the sound structure so that it can cover the entire venue step by step and clearly.

The line array speaker system is composed of a row of sound radiation units arranged in a straight line and spaced very small from each other. These acoustic radiating elements are equal in phase and amplitude.

In the past two decades, the optimization application and development work of Line Array​ has entered a period of rapid development. Many experts and scholars have published a large number of documents on Line Array.
