Noise detection device

The invention relates to a noise detection device. The noise detection device comprises a soundproof box, a loading mechanism and a noise detection module, the loading mechanism comprises a first driving source and a chuck, the chuck is arranged in the soundproof box, the first driving source is arranged outside the soundproof box, the chuck is used for being connected with an output part of a to-be-tested product, and the first driving source is used for driving the chuck to reciprocate in the first horizontal direction; when the driving element of the to-be-tested product drives the output part of the to-be-tested product to reciprocate along the first horizontal direction, the output part bears a load; the noise detection module is at least partially arranged in the soundproof box and is used for collecting noise generated by the driving element and judging whether the noise is within a specified range or not; therefore, vibration noise data of the to-be-tested product in the load state can be obtained, no
