扬声器是广播扩声及公共广播系统的最终终端，将可变范围内的音频电功率信号通过换能器，转变为具有足够声压级的可听声音，扬声器的选择对公共广播系统的良好应用具有重要意义。本文结合工程实例介绍了公共广播扬声器的选择方法。The loudspeaker is the final terminal of the broadcast sound reinforcement and public address system, which converts the audio electric power signal in a variable range into an audible sound with sufficient sound pressure level through the transducer. This article introduces the selection method of public broadcasting loudspeakers in combination with engineering examples.
