Abstract

The invention relates to an abnormal sound detection device for a notebook computer. The abnormal sound detection device comprises a case, a workbench horizontally arranged in the case, a carrying table assembly arranged on the workbench and used for placing the notebook computer, and a detection assembly used for detecting whether the notebook computer makes abnormal sound or not. The carrying table assembly comprises a bearing disc horizontally arranged above the workbench, supporting plates vertically arranged on the two sides of the bearing disc correspondingly and used for connecting the bearing disc and the workbench, a hollow-out part arranged in the middle of the bearing disc and smaller than the bottom area of the notebook computer, two positioning blocks arranged on the bearing disc and located on the two sides of the hollow-out part correspondingly, and a positioning strip arranged on the bearing disc and positioned behind the hollow-out part; the detection assembly comprises a mounting base and a laser vibration sensor which is vertically arranged on the mounting base, and the detection end of the laser vibration sensor penetrates through the hollow-out part and points to the bottom of the notebook computer; the abnormal sound of the bad notebook computer can be accurately distinguished through the laser vibration sensor, manpower is greatly saved, and the testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of notebook computers, in particular to a notebook computer abnormal sound detection device. Background technique [0002] At present, after the notebook computer is assembled, abnormal sound detection is required; before the inspection, the abnormal sound will be defined. If the notebook computer makes an abnormal sound when it is working, it is a defective product. If the notebook computer does not emit abnormal sounds when it is working Sound is a good product. [0003] Existing methods for abnormal sound detection of notebook computers are as follows: The first test method is to place the notebook computer in a silent environment and directly test the decibels of the product’s sound. This detection method has high environmental requirements and is easily affected by external conditions. The second test method is through the human ear, and it is judged as a bad product when it hears the abnormal sound of...

[0003] Existing methods for abnormal sound detection of notebook computers are as follows: The first test method is to place the notebook computer in a silent environment and directly test the decibels of the product’s sound. This detection method has high environmental requirements and is easily affected by external conditions. The second test method is through the human ear, and it is judged as a bad product when it hears the abnormal sound of the laptop. This detection method requires a lot of manpower. Giving the final judgment, and people who concentrate on listening to abnormal sounds for a long time will consume a lot of energy, cause people to be tired, and then lead to misjudgment
