摘要
手持麦、界面麦、佩戴麦等传统扩声设备存在穿戴不便、管理繁琐等诸多痛点。因话筒交叉接触导致新冠肺炎感染,也给传统扩声设备的应用提出了挑战。近年来,音频技术取得新的突破,吊麦扩声系统逐渐应用于越来越多的高校并替代传统扩声设备成为新趋势。基于此,文章首先阐述了吊麦扩声系统的产品形态和技术特征,指出辨别吊麦扩声系统真假与优劣的基本方法。接着,以山东大学为例,分析了扩声系统的选择标准,阐述了吊麦扩声技术在实际应用中的优势。最后,从高校需求的角度对吊麦扩声作了趋势展望。
There are many pain points in the traditional sound amplifying devices such as handheld microphone,interface microphone and wearing microphone,which are inconvenient to wear and complicated to manage.The cross-contact of microphones leading to covid-19 infection also challenges the application of traditional sound amplification devices.In recent years,new breakthroughs have been made in audio technology,and it has become a new trend for the application of the crane and wheat sound reinforcement system in more and more universities to replace the traditional sound reinforcement equipment.Based on this,the paper first describes the product form and technical characteristics of the sound amplification system of the suspended wheat,and points out the basic method to distinguish the true and false of the suspended wheat sound amplification system from the bad.Then,taking shandong university as an example,this paper analyzes the selection criteria of the sound reinforcement system,and expounds the advantages of the technology in practical application.Finally,from the perspective of the demand of universities,the trend of the sound reinforcement of the hanging wheat is prospected.
