A touch control apparatus, a control method thereof and an electronic device having the touch control apparatus are disclosed, which belong to the technical field of touch control. The touch control apparatus comprises: a panel (); a transmitting antenna () arranged on the panel () and configured to transmit a detection wave for detecting whether the panel () is being touched; at least three resonant circuits arranged on the panel and configured to sense the detection wave and generate resonant waves; and a control processing unit () configured to control to process the resonant waves and position information of the resonant circuits to obtain corresponding touch information comprising at least a touch pressure and a touch position. The touch control apparatus, the control method thereof and the electronic device enable touch control of the panel by a general object through utilizing the resonant circuits. The present disclosure can be advantageously implemented by simple process at low cost and have wide usage prospect in the touch control field.

A method for measuring a distance between a coordinate indicator and a coordinate input device, which belongs to the technical field of computer peripheral equipments. The method comprises the steps of measuring an actual amplitude of an output signal of a receiving coil in the electromagnetic induction plate by a measurement circuit in the electromagnetic induction plate; determining a distance between the coordinate indicator and the coordinate input device in accordance with the actual amplitude of the output signal, a nominal amplitude of the output signal, and a preset reference amplitude of signal. In the present invention, the distance between the coordinate indicator and the coordinate input device is determined by converting an actual amplitude of the output signal of the receiving coil at one time to a nominal amplitude of the output signal normalized by a reference amplitude of signal, which overcomes the defect of the prior art which can not indicate a distance between the coordinate indicator and the coordinate input device.
