传统的扩声系统是由音源及其声学环境、调音台、功率放大器、扬声器及其声学环境组成的。主要包括声源和它周围的声环境，把声音转变为电信号的话筒，放大信号并对信号加工的设备、传输线，把信号转变为声信号的扬声器和听众区的声学环境。传统的会议室的扩声系统非常复杂，所以我们看到一般的会议室都会有很多的设备，在无线麦克风广泛使用之前，会议桌常常是杆线密布，异常的杂乱。
The traditional sound reinforcement system is composed of a sound source and its acoustic environment, a mixing station, a power amplifier, speakers, and their acoustic environment. It mainly includes the sound source and its surrounding sound environment, microphones that convert sound into electrical signals, equipment and transmission lines that amplify signals and process them, speakers that convert signals into sound signals, and the acoustic environment of the audience area. The sound reinforcement system in traditional conference rooms is very complex, so we can see that general conference rooms have many devices. Before wireless microphones were widely used, the conference table was often densely packed with poles and wires, which was unusually messy.
柜机等设备占地方不说，要是开召开会议的时候碰上设备问题，对工作人员来说，维修也是很大的一项工程。无感扩声系统出现以后，很大程度地改善了这样的情况。无感扩声系统主要由智能音频主机+吊麦+音响组成，系统非常的简洁。智能音频主机，采用顿厂笔音频处理器，音频调试、中控通讯、录播主机等系统高度集成，集智能混音、自动降噪、混响等多种算法于一身，一键操控，实现扩声的清晰稳定，完全替代了调音台，大大节省了会议室的空间。
Not to mention the space occupied by equipment such as cabinets, if there are equipment issues during a meeting, maintenance is also a significant task for the staff. After the emergence of the insensitive sound reinforcement system, this situation has been greatly improved. The insensitive sound reinforcement system is mainly composed of an intelligent audio host, a suspended microphone, and a sound system, which is very simple. The intelligent audio host adopts a professional DSP audio processor, and the audio debugging, central control communication, recording and broadcasting host and other systems are highly integrated. It integrates multiple algorithms such as intelligent mixing, automatic noise reduction, and reverberation elimination, and is controlled with one button to achieve clear and stable sound reinforcement. It completely replaces the sound mixer and greatly saves space in the conference room.
除此之外，吊麦与智能主机搭配，能够很好地满足语言扩声的应用及兼顾开会时时对动态的要求，吊麦远距离宽范围拾音，经过智能音频主机处理，声压级适中、动态范围大、声场均匀度好、音质优美、语言动听。智慧无感系统现已成为成熟的音频技术，具有一定的性、集成性和可靠性，在科技发展的强劲势头下，能够与录播、远程视频会议结合，满足公司的各项会议需求。
In addition, the combination of hanging microphone and intelligent host can well meet the application of language reinforcement and meet the dynamic requirements during meetings. The hanging microphone can pick up sound in a wide range from afar, and after being processed by the intelligent audio host, the sound pressure level is moderate, the dynamic range is large, the sound field uniformity is good, the sound quality is beautiful, and the language is pleasant. Smart sensorless system has now become a mature audio technology, with a certain degree of progressiveness, integration and reliability. Under the strong momentum of scientific and technological development, it can be combined with recording, broadcasting and remote video conferencing to meet the needs of enterprises for conferences.
