Abstract

Embodiments provide a method for transmitting data between a user terminal and another apparatus. The method has a step of generating a signal for driving an electromagnetic functional unit, the electromagnetic functional unit being an actuator of a loudspeaker of the user terminal or the electromagnetic functional unit being an electromagnetic oscillating circuit connected to the user terminal. Additionally, the method has a step of driving the electromagnetic functional unit by the generated signal to produce, by the electromagnetic functional unit, a magnetic signal which carries first data to be transmitted from the user terminal to the other apparatus. Additionally, the method has a step of detecting another signal output by the other apparatus, the other signal carrying second data to be transmitted from the other apparatus to the user terminal. Thus, the magnetic signal and the other signal differ in the physical signal type.
