摘要
讨论了扬声器谐振频率f0测试的不确定性,对f0测试标准进行了解读,从非线性角度分析了扬声器谐振频率波动的根本原因,并给出了正确的测试方法。
Nondeterminacy of loudspeaker resonance frequency (f0 ) in measurement is discussed. Focus is on the analyzing of root causes leading to the variation of loudspeaker resonance frequency in terms with nonlinear properties of loudspeaker compliance.
