Power supply 103 of the present invention can be independent power interface or power circuit.
Power supply 103 of the present invention can also be the One function module of main control unit 101.
Fig. 3, Fig. 4, Fig. 5 show three kinds of feasible embodiments of first switch circuit.
In the various embodiments shown in Fig. 3 to Fig. 5, first switch circuit 104 has two connection branch roads of branch road first
1041 and second connect branch road 1042, and first switch 1043；First connection branch road 1041 end is port P1, the second connection
The end of branch road 1042 is port P2；The port P1 communicates mould through the first switch 1043 and first near field magnetic induction
During the power input VIO connections of block, define the first switch 1043 and be in first state；The port P2 is through described first
When switch 1043 is connected with the power input VIO of the first near field magnetic induction communication module, the first switch is defined
1043 are in the second state；The outward appearance of first switch 1043 can be button, knob, button, toggle switch etc., its corresponding circuit
It can be the on-off circuit of simple single-pole double-throw switch (SPDT) or a transistor, as long as playing optionally by
One connection branch road 1041 or second connects the voltage input end VIO phases of branch road 1042 and the first near field magnetic induction communication module 102
Even.
In a kind of embodiment of first switch circuit shown in Fig. 3, tie point 1041 is a wire, when user's choosing
Selecting makes first switch 1043 that tie point 1041 to be connected with the voltage input end VIO of the first near field magnetic induction communication module 102
When, the normal working voltage of the first near field magnetic induction communication module 102 of the power supply output end VO outputs of power supply 103 is directly provided
Voltage input end VIO to the first near field magnetic induction communication module 102.
When user needs to close the first near field magnetic induction communication module 102, after toggle switch to port P2, control source
End VIO input voltage falls, and the power management chip 106 inside the first near field magnetic induction communication module 102 can detect confession
Voltage drop, the work of the first near field magnetic induction communication module 102 is cut off by internal control circuit, closes the first near field magnetic induction
Communication module 102.
Meanwhile, the power management chip 106, which to be detected, can be triggered after pressure drop in the first near field magnetic induction communication module 102
Portion's control subsystem link 107 feeds back to main control unit 101 by I2C communication links, and triggering main control unit 101 is no longer with first
Near field magnetic induction communication module 102 is communicated.
When recovering port P1 connections, voltage input end VIO ports recover normal, and the power management chip starts first
The near field magnetic induction communication module 102 and feedback of the information that has been turned on the first near field magnetic induction communication module 102 is to master control
Unit 101, the driving normal work of the first near field magnetic induction communication module 102 of main control unit 101.
Electric capacity 1042a in second branch road so that when closing the first near field magnetic induction communication module 102, its voltage is defeated
0V, protection circuit will not be reduced at once by entering to hold VIO voltage.
Inductance 1042b in second branch road is played a part of being also pressure drop buffering so that when the first near field magnetic strength of closing
When answering communication module 102, its voltage input end VIO voltage will not be reduced to 0V, protection circuit at once.
In a kind of embodiment of first switch circuit 104 shown in Fig. 4, the tie point 1041 can also be voltage
Mu balanced circuit, it is therefore intended that be supplied to the first near field magnetic induction communication module 102 voltage stabilization for exporting VO ends.
In a kind of embodiment of first switch circuit 104 shown in Fig. 5, the tie point 1041 can also be voltage
Conversion equipment, the voltage conversion that power supply 103 is exported is the normal work electricity needed for the first near field magnetic induction communication module 102
Pressure.
In actual applications, as long as providing normal work to the first near field magnetic induction communication module 102 through tie point
It is not depart from present inventive concept as voltage.
Second branch road can also not have electric capacity 1042a, port P2 to be grounded by inductance 1042b, as shown in Figure 4；Institute
Show that port P2 can also be directly grounded, as shown in Figure 5.
In addition, for needing pleasant sports earphones, volume is especially small, and corresponding magnetic induction coil is especially small, and radiation signal is micro-
It is weak, cause first earphone 100 can not perceive second earphone 200, it is impossible to which voice signal is passed into second ear
Machine 200.
To increase the magnetic field energy that first earphone 100 is radiated, to ensure that it is communicated between second earphone 200
It is smooth, the invention allows for a kind of prioritization scheme, as shown in Figure 6.
First near field magnetic induction communication module 102 passes through coil radiation field signal, in this embodiment, output frequency
10.58MHz or other setpoint frequencies.
Increase magnetic core 109 in the magnetic ring coil 108 of the first magnetic induction communication module 102, enhanced rad intensity increases spoke
Penetrate distance.
The port of the antenna 105 of first magnetic induction communication module 102 is LA and LB, and the port is connected 15nH magnetic beads respectively
The two ends of 110 and 111 connection magnetic ring coils 108, are allowed to turn on, the optional model of magnetic bead 110 and 111：0201 encapsulation, Japan is too
Yang You electricity manufacturers, HK060315NJ-T.
Magnetic bead 110 and 111 arrives two, 108 end of magnetic ring coil cabling, walks differential pair cabling, line width, line length is as far as possible identical.
Add magnetic core 109 in the middle of magnetic ring coil 108, the parameter of magnetic core 109 is adapted to 10MHz high frequency characteristicses, and increase magnetic flux is strong
Degree, increases radiation length, and present case magnetic core 109 adds up to material, the production of ISE companies, model 90001977D using high crystal silicon.
Those skilled in the art can make according to prior art without departing from the spirit of the invention
Various change, for example, one low-tension supply of port P2 connections, the low-tension supply can trigger first near field magnetic induction and lead to
The power management chip 106 for interrogating module 102 closes the work of the first near field magnetic induction communication module 102, and ensures described the
One near field magnetic induction communication module 102 can notify that main control unit 101 stops communicating.
Although some specific embodiments of the present invention are described in detail by example, the skill of this area
Art personnel are it should be understood that example above is merely to illustrate, the scope being not intended to be limiting of the invention.The skill of this area
Art personnel to above example it should be understood that can modify without departing from the scope and spirit of the present invention.This hair
