Since the reform and opening up, China's professional audio sound reinforcement industry has gradually achieved a leap from imitation to innovation, from OEM to brand creation after nearly 50 years of development. In major projects such as international conferences, G20 summits, and China International Import Expo, more and more places have seen the presence of Chinese sound reinforcement system brands, allowing the world to hear the voice of China.

1. Overview of conference acoustic sound reinforcement system

Before the 1980s, due to the limitation of conditions, most of the information dissemination methods were mainly based on language sound reinforcement. That is, the voice of the person speaking with voice amplification is amplified so that more people can hear it. After the 1990s, with the popularization of multimedia technology and the large-scale use of large screens as display means in conferences, the playback of relevant audio and video materials has also entered people's field of vision.

Its applications cover almost all conference rooms, multi-function halls, command halls, foreign affairs receptions, press releases, technical forums, conference audio, etc. Therefore, conference audio sound reinforcement system has become an indispensable part of social development, sometimes It has even become an important part of the completion acceptance of the whole project. There are many forms: speech, report, discussion, teleconference. Due to the different number of people participating in the meeting, the size of the venue, indoor or outdoor, and different functional requirements, the sound reinforcement system of the conference audio system will also vary widely and in different shapes. The perfect function of the conference system is not only reflected in the hall environment, but also pays attention to the aesthetics and visual effects of the decoration. According to the environment of the venue, the pursuit of practical functional sound effects has both beautiful decorative effects and good sound quality. be enjoyed. Practical reliability is the key to conference systems. Therefore, the conference system should not only consider voice reinforcement, but also consider the playback and storage of audio and video signals.

With the development of the times, people are increasingly pursuing high-level and high-quality spirit. Psychoacoustics tells us that people's cognition and appreciation of sound has a development process from low-level to chaotic, from perceptual to rational, and the listener gradually establishes the external image and internal image of the sound. Invisibly affects people's thinking and sound judgment. These images stimulate the listeners, inner feelings give the listeners emotional stimulation, and inner feelings give the listeners emotional changes. This is the connotation of psychology.

Therefore, the development goal of conference acoustic sound reinforcement technology is not only to use the language content of the speaker as a carrier, but to convey the emotion of the speaker. And make the emotion expressed by the speaker's language more appropriate to the listener, so that the speaker's voice can really reach the effect of infecting the audience's emotions.

However, some people think that the technical difficulty and requirements of conference sound reinforcement are not high. However, the sound reinforcement of the small sound reinforcement system commonly used in the actual conference audio has its particularity and complexity, which implies a great technical difficulty.
