Abstract
A touch control device, electronic apparatus and control method thereof. The touch control device includes a processor and a plurality of transceivers disposed in an array. The transceivers is used to transmit ultrasonic waves and receive ultrasonic waves that are reflected back, and directions in which the plurality of transceivers transmits the ultrasonic waves are parallel to one another. The processor is connected to each transceiver and used to determine a touch control signal in accordance with at least one of a time difference between time at which each transceiver transmits the ultrasonic waves and time at which each transceiver receives the ultrasonic waves and an intensity difference between the transmitted and received ultrasonic waves, and to control the touch control device in accordance with the touch control signal, in which the touch control signal comprises at least one of an operation instruction and user fingerprint information.
