Harmonic distortion test for audio directional loudspeaker
声频定向扬声器谐波失真测试
The harmonic distortion of the double side band(DSB) algorithm for the audio directional loudspeaker is investigated.
依据一种新型扬声器——声频定向扬声器的基本工作原理,从理论上给出了DSB算法中调制系数对输出信号谐波失真影响的详细推导过程;并指出调制系数越小,失真度越小,但带来的负面效应是小的调制系数将使输出的信号功率相应变小。
Discussion on Impedance Curve of Micro Loudspeaker
关于微型扬声器阻抗曲线的一些探讨
Two types of power amplifier for measuring speaker impedance curve were analysed.
分析了2种应用于测量扬声器阻抗曲线的功率放大器。
Even if the volume of the speaker is changed, the impedance of the circuit is kept constant.
即使扬声器的音量改变了，电路的阻抗保持不变。
Sometimes they present a capacitive load, sometimes they present an inductive load, sometimes simply resistive, sometimes a combination of these.
而且，事实上，扬声器系统的实际电阻从来没有等同于它的额定阻抗。
Technically, the damping factor is the specified load impedance( in use, that'd be the speaker system) divided by the amplifier's output impedance.
技术上，阻尼因子就是指定的负载阻抗（践中，也就是扬声器系统）以放大器的输出阻抗。
acoustic impedance density
声阻抗密度，声阻抗率
There is another implication lurking here; speakers with lower resistances will support higher current drive.
这还意味着，低电阻的扬声器能支持更高的电流。
As most of us are aware, speakers are not pure resistive loads.
大部分人都知道，扬声器不是纯粹的电阻性负载。
