| 中文摘要: |
| 通过分析和比较两种扬声器涡流电学模型和两种扬声器热模型,提出一种分频段的非线性热模型类比线路,给出了对应的音圈稳态温度公式,并在高频段运用逐点测温的方法研究,论证了扬声器涡流随频率变化的规律及其对扬声器热效应的影响。 |
| 英文摘要: |
| Two electrical models of loudspeaker eddy current and two thermal models of loudspeaker are analyzed and compared. A frequency-divided nonlinear analogy circuit of the thermal model is proposed. The corresponding steady-state temperature expression of the voice coil is given and studied by measuring the temperature spot by spot in the high frequency range. So we can discuss the way with which the eddy current in the loudspeaker changes with frequency and its effect on the thermal performance of loudspeakers. |
