[0002] Audio detection can be used to effectively detect and test various industrial parts and products, and to evaluate their integrity, safety and reliability and other performance indicators. It is an important means to inspect quality, improve processes, and ensure equipment safety. There are many detection technologies using audio principles, which can be divided into active and passive types according to the sound source generation mode, and can be divided into amplitude and spectrum according to the parameter identification mode. Relevant fault information can be extracted from various sound parameters of audio detection, including characteristic information such as the defect type, size, location and change trend of the workpiece. The reflection of defects is authentic and real-time, so it is suitable for online rapid detection of finished and semi-finished workpieces. Except for noise, it does not require other environmental conditions. When existing audio detection equipment detects parts, it is easy to cause inaccurate detection results because there is no fixed method.

[0021] For example, when working, the body 1 is first connected to the intelligent terminal using the data transmission port 401, and then the cover 2 is removed to place the part to be tested on the first audio signal collector 101. At this time, the threaded rod 505 is operated by turning the knob 506, so that the clamping plate 504 clamps the test piece and the second audio signal collector 507 is close to the test piece, thereby completing the clamping work.
