一、引言组合扬声器(箱)测量时,如何确定测试参考点,参考轴及测量距离,是很重要的。所谓参考点,就是测量时测试传声器对准被测组合扬声器(箱)平面的那一点。参考轴是通过参考点垂直于辐射平面的一条直线。沿参考轴从参考点到测试传声器的距离,就是测量距离。组合扬声器(箱)是由多只扬声器单元组合而成的,其辐射声场比单只扬声器辐射声场要复杂得多。因而在测量工作中就不能简单地仿照测量单只扬声器那样进行了。应如何正确的 I. INTRODUCTION It is very important to determine the test reference point, reference axis and measurement distance when measuring the combined speaker (box). The so-called reference point, is measured when the test microphone at the measured combination speaker (box) plane that point. The reference axis is a straight line perpendicular to the radiation plane through the reference point. The distance from the reference point to the test microphone along the reference axis is the measurement distance. The combined loudspeaker (box) is a combination of multiple loudspeaker units whose radiated sound field is much more complex than the sound field radiated by a single loudspeaker. Therefore, in the measurement work can not simply follow the measurement of a single speaker did. How should be correct
