Vibration noise collector

Abstract

The invention provides a vibration noise collector. The vibration noise collector comprises a mounting frame used for limiting a product to be tested, noise collection devices used for collecting vibration noise of the product to be tested and a power connecting and disconnecting device used for connecting and disconnecting power of the product to be tested, wherein the noise collection devices are opposite to the product to be tested; each noise collection device comprises an elastic sheet and an acceleration sensor; each acceleration sensor is mounted on each elastic sheet. According to thevibration noise collector, the noise collection devices and the power connecting and disconnecting device respectively act on the product to be tested, so that the vibration noise information of theproduct to be tested is automatically collected; the vibration noise collector is simple in structure and compact and reasonable in layout; the testing results can be transited from artificial feelingto testing quantification; the accuracy and the controllability of the testing results are improved; meanwhile, the elastic sheets and the acceleration sensors of the noise collection devices cooperate with each other; the accuracy of the testing data collected by the acceleration sensors is ensured; and the accuracy of the testing results is further improved.

Description

technical field [0001] The invention relates to the technical field of automatically testing the noise of electronic appliances, in particular to a vibration and noise collection machine. Background technique [0002] The existing vibration and noise tests in the electronic and electrical industry are all manual tests. Manually hold the product by hand, then switch on and off the corresponding voltage of the product, feel the vibration degree of the product with the hand, and listen to the sound made during the product test with the ear. Then judge whether the product is qualified. Since the test results are completely dependent on subjective perception and judgment, all tests cannot be quantified, which will lead to many uncertain factors in the judgment results. It is impossible to intuitively and accurately judge whether the product is qualified, and the test results are not accurate. At the same time, the way of manual testing, Time-consuming and labor-intensive, increa...

Since the test results are completely dependent on subjective perception and judgment, all tests cannot be quantified, which will lead to many uncertain factors in the judgment results. It is impossible to intuitively and accurately judge whether the product is qualified, and the test results are not accurate. At the same time, the way of manual testing, Time-consuming and labor-intensive, increasing labor costs
