Problems solved by technology

[0004] However, due to the limitation of the packaging process, winding the coil in the small space of the SIM card or SD card limits the available area and number of turns of the low-frequency coil, reduces the performance of the low-frequency coil, and may affect the distance in practical applications. The control has a certain impact, and at the same time, this method will indirectly increase the user's cost of use, thus directly affecting the user's experience

Embodiment 1

[0058] Please refer to figure 1 , is a schematic structural diagram of the mobile terminal in this embodiment. This embodiment is a mobile terminal, including: a control unit, a magnetic signal sending unit, a magnetic signal receiving unit, a radio frequency communication unit, a first coil, and a second coil; the control unit controls the sending and receiving of the magnetic signal and The received magnetic signal determines whether to turn on the radio frequency communication unit; the magnetic signal sending unit is used to convert the signal generated by the control unit into a magnetic signal according to the sending parameters set by the control unit; the first The coil sends out the magnetic signal generated by the magnetic signal sending unit; the second coil receives the external magnetic signal and transmits it to the magnetic signal receiving unit, and the magnetic signal receiving unit is used to set the magnetic signal according to the control unit Receiving pa...

Embodiment 2

[0064] Please refer to Figure 4 , Figure 4 It is a schematic structural diagram of the mobile terminal system of this embodiment. The mobile terminal system in this embodiment includes: at least two mobile terminals as described in Embodiment 1, where the mobile terminals exchange magnetic signals through the first coil and the second coil, and exchange radio frequency signals through the radio frequency communication unit. Such as Figure 4 The mobile terminal system shown in includes a first mobile terminal and a second mobile terminal. The first mobile terminal first performs magnetic signal interaction with the second mobile terminal to determine whether the two parties are within the preset range. If it is determined to be within the preset range, the two mobile terminals establish a radio frequency communication connection, and exchange large-capacity data through the radio frequency communication unit.

[0065] Further, the mobile terminal system of this embodiment...

Embodiment 3

[0067] refer to Figure 5 , is a framework flowchart of the mobile terminal signal transmission method in this embodiment. In this embodiment, any one of the communication mobile terminals is the active communication party, and the other is the passive communication party. The first coil comes from the speaker, and the second coil comes from the microphone. The performance parameter of the magnetic signal is the strength of the magnetic signal. The specific steps of the mobile terminal signal transmission method of the embodiment are as follows:

[0068] Step A1, the active communication party selects the magnetic signal transmission function, sets transmission parameters such as the frequency point, encoding and modulation mode, and transmission power of the magnetic communication, and sends the magnetic signal to be transmitted through the speaker;

[0069] Step A2, the passive communicating party selects the magnetic signal receiving function, sets receiving parameters suc...

Abstract

The invention discloses a mobile terminal, a mobile terminal system and a mobile terminal transmission method. The mobile terminal comprises a control unit for controlling sending and receiving of a magnetic signal and judging whether a radio frequency communication unit is started or not based on the received magnetic signal, a magnetic signal sending unit for converting a signal produced by the control unit to be a magnetic signal according to a sending parameter set by the control unit, a first coil for sending out the magnetic signal produced by the magnetic signal sending unit, a second coil for receiving an outside magnetic signal and transmits the outside magnetic signal to a magnetic signal receiving unit, the magnetic signal receiving unit for receiving the magnetic signal received by the second coil based on a receiving parameter set by the control unit, processing the magnetic signal and transmitting the magnetic signal to the control unit, and the radio frequency communication unit for performing data communication of a large capacity with the outside. According to the mobile terminal, the mobile terminal system and the mobile terminal transmission method, bidirectional magnetic communication connection is built up according to the first coil and the second coil brought by the mobile terminal, and therefore both sides of communication can transmit data and information safely and reliably within a limited communication distance.

Description

technical field [0001] The invention relates to a mobile terminal, a mobile terminal system and a mobile terminal signal transmission method. Background technique [0002] With the development of wireless communication technology and the popularization of mobile terminals in recent years, mobile terminals play an increasingly important role in people's lives, and there are more and more demands for short-distance communication using mobile terminals, especially in the security Payment fields with high requirements. Several short-distance wireless communication schemes currently popular in mobile terminals include NFC (Near Field Communication, near field communication), RFID-SIM card (Subscriber Identification Module, subscriber identification module) and RFID-SD card (Secure Digital , digital security) and other programs. The NFC solution achieves short-distance communication between each other by adding a near-field communication module in the mobile terminal; the RFID-S...
