Abstract: An abnormal sound detection device for detecting a peripheral interface device includes a vibration simulation mechanism, an audio collecting device with plural audio collectors, and a controlling and analyzing device. The peripheral interface device generates a vibration sound wave in response to a vibration force from the vibration simulation mechanism. The plural audio collectors are used to collect the vibration sound wave and generate a vibration audio signal. The plural audio collectors are divided into at least two audio collection units. The controlling and analyzing device generates an abnormal sound detection signal. The vibration audio signal is inputted into the controlling and analyzing device. The controlling and analyzing device detects and identifies whether there is an abnormal sound phenomenon in the vibration audio signal. The abnormal sound detection signal contains at least two abnormal sound detection sub-signals in serial sequence.

Abstract: A time synchronization method is provided. Firstly, an update time of a second playing device is calculated according to a first system time of transmitting a first packet from a first playing device and a second system time of receiving the first packet by the second playing device. Then, a first difference value is calculated according to the first system time of transmitting a second packet from the first playing device and the update time corresponding to the reception of the second packet by the second playing device. If plural first difference values are all smaller than a first predetermined value, a second difference value is calculated. If the second difference value is smaller than a second predetermined value, a synchronization time is obtained according to the second difference value and the update time.

Abstract: A method for synchronizing audio playback includes following steps. Firstly, a first playing device is set as a master playing device. Then, a second operation status of a second playing device is switched to a first operation status of the first playing device. In response to an action command, a first time information of the first playing device is transmitted to the second playing device. By comparing the first time information with a second time information of the second playing device, the second playing device and the first playing device start the audio playback. The first time information and the second time information are continuously compared with each other, and a playback progress of the second playing device is correspondingly adjusted. Consequently, the audio playback of the second playing device and the first playing device are synchronized.
