System, for the ordinary skill in the art, can understand the concrete meaning of above-mentioned term as the case may be.
Fig. 1 is the structural schematic diagram of the charging assembly of the utility model embodiment, as shown in Figure 1.
The utility model embodiment provides a kind of charging assembly, comprising: input terminal 10, use for connecting with charging source
In output end 20, charging circuit 30, battery 40 and the switch unit 50 of output electric energy.
Wherein, input terminal 10 is connect with one end of charging circuit 30.The charging of the other end and battery 40 of charging circuit 30
End connection.The discharge end of battery 40 is connect with one end of switch unit 50.The other end of switch unit 50 is connect with output end 20.
When switch unit 50 is acted on by external magnetic force, switch unit 50 disconnects logical between battery 40 and output end 20
Road, input terminal 10 can be that battery 40 charges through overcharge circuit.When external magnetic force disappears, switch unit 50 is connected to battery 40
With the access between output end 10, battery 40 can be powered outward by output end 20.

For one of magnet, magnet steel or electromagnet.When conductive armature 54 is magnet or magnet steel, magnetic force is played to conductive armature 54 and is made
It can be one of opposite polarity magnet, magnet steel or electromagnet.
In the utility model embodiment, the implementation of elastic component 53 includes a variety of, for example, elastic component 53 is to include but not
It is limited to tension spring.Tension spring structure is simple, facilitates operation, reduces production cost.Certainly, elastic component 53 can also be elasticity
Rubber, elastic slice etc..
In a kind of achievable embodiment of the utility model, the other end of charging circuit 30 also connects with switch unit 50
It connects, with reality there are currently no external magnetic force effect, charging source exports electric energy by output end.For example, the earphone with charging assembly
It can directly be connect by input terminal with terminal device, the output end of charging assembly is connect with earphone system.Terminal device is charging
Battery charging in component, while powering for earphone system.When outside has magnetic force, in switch unit 50 by external magnetic force
When effect, switch unit 50 disconnects the access between charging circuit 30 and output end 20；When external magnetic force disappears, switch unit 50
The access being connected between charging circuit 30 and output end 20.
Further, in the utility model embodiment, charging circuit 30 includes power supervisor and current-limiting resistance.Switch is single
The charging end of member 50 and battery 40 is connect with power supervisor.Current-limiting resistance one end is connect with power supervisor, the other end with
Ground wire connection.Power supervisor is used to for the electric energy that charging source exports to be converted into the applicable electric energy of battery.Specifically, pass through earphone
When charging box is that earphone charges, the voltage of earphone charging box output may be greater than or less than the voltage being suitable for as battery charging,
Greater than when can to battery at damage, less than when cannot complete to charge.Meanwhile earphone charging box output voltage it is possible that
Fluctuation, causes charging voltage unstable, equally will cause damage to battery.Earphone charging box can be exported by power supervisor
Voltage be adjusted to be suitable for the voltage for battery charging, while power supervisor can also ensure that output at the voltage of battery
In stable state.Guarantor is provided for battery when being battery charging operation by using earphone charging box by power supervisor
Shield effect.Current-limiting resistance is that power supervisor carries out Current limited Control.Current-limiting resistance at least two.
