An audio vibration apparatus using a USB port as a power inlet primarily comprises a housing, a circuit board, an electromagnetic converting device and a soft pad. Therein the electromagnetic converting device is constructed from an electromagnetic converting coil assembly, an upper metal element and a lower metal element. Thereby, an external signal can be transmitted through the USB port settled on the circuit board to a processing unit of the circuit board so as to drive the electromagnetic converting device to generate a vibration frequency that resonates a soft pad to impact a plane object and therefore give off a sound.
