摘要
主要对Audussy及Toshiba带座传声器构成的被测产品的频响特性测量进行了讨论,说明了不同形状及尺寸的被测品对传声器频响特性曲线的影响。在实测中由于产品的形状、尺寸和安放位置对频响特性测量的影响,结果表明在5kHz以后其受衍射影响明显,且传声器底座的多棱角及相对声源的安放位置对频响特性测量也同样表现得突出,这对实际应用有参考意义。
The measurement of the microphone with base is discussed. Due to the effect of the shape,size and placement location, the frequency response curve more than 5 kHz is obviously affected by the diffraction. And however, the frequency response curve is more obviously affected by the polygon of the cone and the placement location of the sound source.
