Abstract
A resonant testing system for testing a device under test, including a processing circuit, a microphone array and a camera is disclosed. The processing circuit generates a scanning frequency signal and transmits the scanning frequency signal to the device under test, which plays sound based on the scanning frequency signal. The microphone array includes several microphones, each of the microphones receives the sound played by the device under test, and the microphone array outputs several audio signals corresponding to the microphones. The camera captures a real time image signal of the device under test, and transmits the real time image signal to the processing circuit. The processing circuit computes resonant positions and resonant levels according to the audio signals, and combines the resonant positions, the resonant levels and the real time image signal to generate a real time resonant result. A resonance testing method is disclosed.
