This invention discloses an intelligent aging cabinet for an automatic aging system in the audio industry, relating to the field of aging equipment technology. The aging cabinet body has an inlet and an outlet on opposite sides. A first and second isolating component intermittently unblocks either the inlet or outlet. During the process from when the audio product enters the aging station to when the aging cabinet body outputs the audio product that has completed the aging test, at least one of the first and second isolating components, together with the aging cabinet body, isolates the internal environment of the aging cabinet body from the external environment. This reduces noise pollution to the surrounding environment. Thus, while some audio products are still undergoing aging tests inside the aging cabinet, some audio products that have completed the aging test can be output from the aging cabinet body, while simultaneously inputting some audio products awaiting aging tests into the aging cabinet body. This shortens the waiting time for inputting and outputting audio products, resulting in higher overall efficiency when aging tests are performed on batches of audio products.
