明确阐述了扩声系统设计中所要涉及的扬声器噪声功率、扬声器的峰值功率、扬声器的最大声压级、扬声器的额定阻抗、功放的输出功率、功放的输入灵敏度,以及功放与扬声器的功率匹配等基本参数,并以两例具体工程案例,详细给出了参数的计算过程、设备的选配,还特别指出了设计和调试过程中常见的错误及解决的方法。
Clarify the speaker noise power, the peak power of the speaker, the maximum sound pressure level of the loudspeaker, the rated impedance of the loudspeaker, the output power of the power amplifier, the input sensitivity of the power amplifier and the power matching between the power amplifier and the loudspeaker etc. Basic parameters, and two cases of specific projects, given in detail the parameters of the calculation process, equipment matching, but also in particular pointed out the design and debugging process common errors and solutions.
