摘　　要：楼宇对讲系统在新建智能社区、商品房的应用越来越多,从非可视的手柄式对讲逐步升级至可视免提对讲智能终端,并融入了智能家居控制终端、报警终端等多种扩展功能,但作为楼宇对讲最基础和最重要的功能,对讲的语音质量直接影响到用户的使用体验,并且对讲状态后执行楼宇对讲作为小区入口、楼栋门或入户门开锁动作,因此楼宇对讲系统的语音可理解性实际上已经涉及一定的安全问题,持续提升楼宇对讲的语音质量是楼宇对讲制造商面临的难题和努力的目标。楼宇对讲系统的电声设计涉及结构、硬件及软件设计,故文章对楼宇对讲系统的电声进行分析和探讨,阐述包含麦克风和扬声器结构、音频电路及系统统调的设计。As building intercom system is more and more used in intelligent community and commercial residential building,the non-visual handle intercom escalate into visual hands-free intercom integrate into several extra functions like smart home control terminal,alarm terminal and so on.However,as the most basic and important function of building intercom,the voice quality will directly influence user experience and unlock function for entrance of residential area,building door or entry door.Therefore,the voice intelligibility of building intercom system actually is already involved in certain safety issues,continuous improve voice quality of building intercom is the challenge and object of building intercom manufacturer.Electro-acoustic design of building intercom system involves structure,hardware and software design.This essay analyzes and discusses the electro-acoustic of building intercom system,expounds the design which includes microphone and speaker structure,voice-frequency circuit and system unit adjustment.
