文档介绍：摘要
随着社会的的发展,音响与视频技术已经渗透到社会生活的各个角落,从多媒体教室、会议室的扩声系统、音乐厅、电影院的专业视听系统,到商场、车站等的公共广播系统,到各处都可见到的各类音响系统设备在为人们的工作、生活服务虽然音响技术发展至今只有一百多年,但发展速度非常迅速。目前已经完成,正在使用的音响系统数量非常多,将要建设的数量同样非常大。由于各种的原因,很多正在使用的音响系统中有不少面临着更新设备的任务。所以目前音响系统工程设计的项目非常多,并且对音响的质量要求也很高。
因此,此次选题的目的就是运用一些音响设备,通过对KTV包房的面积进行计算来确定功率放大器和扬声器的选用功率和数量,还有传声器等一些主要的音响设备对KTV的音响系统进行设计,以达到一个高标准的试听效果。
关键词:扬声器,传声器,功率放大器
Abstract
With the social development, audio and video technology has permeated every corner of life, from the multi-media classrooms, conference rooms, PA system, concert halls, cinemas professional audio-visual system, to shopping malls, railway stations and other public broadcasting system, can be seen from place to place equipment in various types of sound system for people working and living services, though the development of sound technology has only been a hundred years, but the development speed is very fast. Has pleted, the number of sound system is being used very much, will want to build a very large number of the same. For various reasons, many are using the sound system has many faces the task of updating equipment. Therefore, the current sound system engineering design project is very large, and the audio is also very high quality requirements.
Therefore, the purpose of this topic is to use some audio equipment, KTV rooms of the area through the calculation to determine the choice of amplifier and speaker power and volume, as well as microphones and other audio equipment, some of the main sound system for KTV Designed to achieve a high standard of the audition results.
Keywords: speaker, microphone, power amplifier
