1. An abnormal sound detection device for detecting a peripheral interface device, the abnormal sound detection device comprising:
a vibration simulation mechanism comprising a mechanism body, wherein the peripheral interface device is accommodated within the mechanism body, the vibration simulation mechanism generates a vibration force, and the peripheral interface device generates a vibration sound wave in response to the vibration force;
a movable-type audio collecting device located near the mechanism body, wherein the movable-type audio collecting device collects the vibration sound wave, and the audio collecting device generates a vibration audio signal in response to the vibration sound wave; and
a controlling and analyzing device electrically connected with the vibration simulation mechanism and the movable-type audio collecting device, wherein the controlling and analyzing device generates an abnormal sound detection signal to control the vibration simulation mechanism to generate the vibration force, the vibration audio signal from the audio collecting device is inputted into the controlling and analyzing device, and the controlling and analyzing device detects and identifies whether there is an abnormal sound phenomenon in the vibration audio signal,
wherein the abnormal sound detection signal contains a movement control sub-signal and a test sub-signal, the movement control sub-signal is transmitted to the movable-type audio collecting device, and the test sub-signal is transmitted to the vibration simulation mechanism,
wherein in response to the movement control sub-signal, the plural movable audio collection units are moved along plural movement trajectory segments and plural stopping points over the peripheral interface device in a go/stop mode, wherein when the movable-type audio collecting device is moved to the plural stopping points, plural effective identification vibration audio sections of the vibration audio signal are generated, wherein the plural movement trajectory segments are separated from each other by the plural stopping points.
