我们最便宜的扬声器必须进行检测并且必须通过如同我们的专业扬声器必须通过的测试。
Our least expensive speaker is tested and must pass the same tests as our professional speakers.
而且，在电路基板(100)中设置开口区域，在其上装载扬声器(2)，由此对微小结构体的可动部输出测试声波。
The circuit substrate (100) is provided with an aperture region. As the speaker (2) is disposed on that region, a test sound wave is output to the moving section of the microstructure.
我们测试的PF 30的电力线分析仪，提供即时，声音反馈的噪声任何特定出口通过内置扬声器和音量控制。
We tested the PF30 with a power-line analyzer that provides immediate, audible feedback on the noisiness of any given outlet via a built-in speaker and volume control.
如此，我然后测试了低音扬声器在一个被密封的箱子。
介绍美国DRA实验室研制的基于最长序列MLS信号测试技术的扬声器电声分析系统MLSSA。
A brief introduction to MLSSA(Maximum-Length Sequence System Analyzer)is presented, which is developed over the MLS signal theory by DRA laboratories, U. S.
最后，构建了一实验系统，该系统由信号源、功放阵列和扬声器阵列组成，并在实验室环境下完成了线阵列扬声器组的指向性实验和测试。
At last, we design an experimental system including signal source, power amplifier array and loudspeaker array. Some experiments of the directive property of loudspeaker array are completed.
