The processing module 40 is electrically connected to the first microphone 21 and the second microphone 22, thereby receiving the first audio signal and the second audio signal. Since the first audio signal and the second audio signal are generated according to the received first audio signal and the second audio signal, the first sound signal and the second sound signal should have different frequencies under normal conditions, and should be consistent with The frequency of the original first audio signal and the second audio signal. Therefore, the processing module 40 is configured to determine whether the first audio signal and the second audio signal meet the frequency of the first audio signal and the second audio signal to determine whether the first speaker 2a and the second speaker 2b are normal. When the processing module 40 determines that the first audio signal is normal, the first determination signal is generated. In addition, when the processing module 40 determines that the second audio signal is normal, the second determination signal is generated.

The computer system 30 is electrically connected to the test aid 20, for example, using an RS232 serial data communication interface to transmit signals, but the invention is not limited in this manner. When the processing module 40 generates the first determination signal or the second determination signal, the computer system 30 determines that the first speaker 2a or the second speaker 2b is in a normal state according to the first determination signal and the second determination signal, thereby being synchronized. Inform the tester or record the test results simultaneously.

In addition, the test assisting device 20 can also have a first lighting module 23 and a second lighting module 24 . The first light emitting module 23 and the second light emitting module 24 may be a light emitting diode, but the invention is not limited thereto.
