Claim:
1. A touch-sensing apparatus, installed in a periphery of a sensing surface and configured to sense a position of a touch object operated on the sensing surface, the touch-sensing apparatus comprising: a signal-receiving module, comprising: a control unit electrically connected to the mechanical wave-receiving unit and the electromagnetic wave-receiving unit and configured to decide an azimuth angle of the touch object on the sensing surface with respect to the signal-receiving module according to the electromagnetic wave signal received by the electromagnetic wave-receiving unit, decide a distance of the touch object on the sensing surface with respect to the signal-receiving module according to a time difference between time of the mechanical wave signal being received by the mechanical wave-receiving unit and time of the electromagnetic wave signal being received by the electromagnetic wave-receiving unit, and decide the position of the touch object on the sensing surface according to the azimuth angle and the distance.
