ZCLK-001A Acoustic Laser Analyzer can test the performance parameters of electroacoustic products, including frequency response curve, impedance curve, harmonic distortion, intermodulation distortion, abnormal sound test, etc.
Among them, the abnormal sound test is the weakness of the traditional test system. The so-called rub and buzz refers to the annoying noise generated when the speaker is tested with a sweep signal, which is caused by the nonlinearity of the system. The abnormal sound is mostly caused by the manufacturing defects of the speaker, such as loose diaphragm, loose coil, non-center diaphragm, coil friction, air leakage or other defects. These defects cause short pulses to have a sudden change in instantaneous energy, resulting in disturbing noises. The trained listener can distinguish the abnormal sound effectively, but it requires a lot of manpower and material resources, and hearing fatigue will reduce the accuracy of the test, so it is not suitable for product testing on the production line.
