• 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;
• an audio collecting device with plural audio collectors, wherein the plural audio collectors are located near the mechanism body to collect the vibration sound wave, and the audio collecting device generates a vibration audio signal in response to the vibration sound wave, wherein the plural audio collectors are divided into at least two audio collection units, and the at least two audio collection units are respectively distributed and located near at least two different regions of the peripheral interface device;
• and
• a controlling and analyzing device electrically connected with the vibration simulation mechanism and the 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 at least two abnormal sound detection sub-signals in serial sequence, and the at least two audio collection units of the audio collecting device are selectively enabled in turn at different time points in response to the at least two abnormal sound detection sub-signals, and the vibration simulation mechanism is controlled to generate the vibration force in response to the at least two abnormal sound detection sub-signals, and the peripheral interface device generates the vibration sound wave in response to the vibration force,
• wherein when the at least two audio collection units are enabled at the different time points, the enabled audio collection units generate corresponding vibration audio unit signals to the controlling and analyzing device, so that corresponding abnormal sound analysis processes are performed, wherein the vibration audio unit signals are arranged in serial sequence and formed as the vibration audio signal.
