then, the control column 18 is rotated to drive the piston 318 to rotate, so that the conducting block 32 is abutted against the transduction and emission crystal 2, and then the device is connected with an oscilloscope, and at the moment, the sound wave can be detected.
According to the above process, the device is adopted, because the upper surface and the lower surface of the conductive block 32 are respectively attached to the transduction receiving crystal 33 and the transduction transmitting crystal 2, the contact area among the conductive block 32, the transduction receiving crystal 33 and the transduction transmitting crystal 2 can be effectively increased, the coupling effect among the three can be improved, and the attaching degree and the contact stability among the three can be improved. Therefore, since the conductive block 32, the transduction receiving crystal 33 and the transduction transmitting crystal 2 are relatively adhered, when the transduction receiving crystal 33 or the conductive block 32 is pressed and fixed, the risk of sliding among the transduction transmitting crystal 2, the conductive block 32 and the transduction receiving crystal 33 is effectively reduced, and the phenomenon of weakening of the contact strength among the transduction transmitting crystal 2, the conductive block 32 and the transduction receiving crystal 33 is greatly reduced. Therefore, the design can obviously reduce the risk of weakening and even interrupting the transmission of the sound wave excited by the vibration of the transduction emission crystal, thereby realizing the purpose of quick, convenient and reliable transmission of the sound wave and further improving the test efficiency and the test accuracy.
