本文简明地介绍了国外广播传声器的现有发展。阐明了各种传声器的基本原理,着重说明了电容式与动圈式传声器的工作方式。文中还叙述了广播传声器的应用方法,介绍了立体声拾音制式的最新动态。由于传声器是广播的第一关,如果传声器选用不当或放置欠佳,所产生的不良后果往往不能在以后各环节予以校正,因此本文对设计与使用传声器的读者有一定的参考价值。本文分两部分刊登,第二部分将在下期刊登。 This article briefly introduces the current development of foreign broadcasting microphones. Clarified the basic principle of various microphones, focusing on the work of condenser and moving coil microphones. The article also describes the application of radio microphones, introduced the latest stereo pickup system. As the microphone is the first radio, if the microphone improperly placed or placed poor, the resulting adverse consequences often can not be corrected in the future, so this article on the design and use of microphone readers have some reference value. This article is published in two parts, the second part will be published in the next issue.
