In addition, the clamping microphone 50 on the test fixture 40 corresponds to the motor 60 on the test platform 10. When the motor 60 is working, the microphone 50 can receive the sound of the motor 60 starting and working. The microphone 50 can transmit the collected sound information to the control system of the test platform 10, and the control system can recognize the sound information to perform noise detection of the motor 60.

[0030] In addition, since the test fixture 40 is connected to the test platform 10 by a positioning connector, and the positioning connector can adjust the angle and position of the test fixture 40, that is, the position of the microphone 50 clamped by the test fixture 40 can be adjusted according to the position of the motor 60, such as up and down position adjustment or left and right position adjustment, or rotation for angle adjustment, the microphone 50 is allowed to be flexibly positioned at any position around the motor 60, making it convenient to find the best sound collection point.
