Step 1: wireless microphone is inserted on the cradle, and by described induction coil induction alternating current;
Step 2: described alternating current enters charging management chip through after shaping, filtering and the step-down;
Step 3: described charging management chip charges to described rechargeable battery;
Step 4: when the charging pin of described charging management chip detects setting voltage value, stop charging.
Preferably, the setting voltage value in the described step 4 is 4.2 volts.
Preferably, described charging management chip is chip TP4056-42-SOP8-PP.
The present invention also proposes a kind of wireless microphone charging circuit, and it comprises control chip, is connected with power supply module, charging circuit on the described control chip, and described charging circuit is connected with the induction charging module that is provided with induction coil.
Preferably, described control chip is charging management chip TP4056-42-SOP8-PP.
Preferably, described induction charging module comprises induction coil and rectification filtering module.
Preferably, described charging circuit comprises voltage reduction module.
Wireless charging microphone of the present invention can adopt contactless wireless charging technology that it is charged, and has following beneficial effect:
1. reduce the human cost that the detachable charging modes brings;
But 2. charge complete after the automatic disconnection charge mode, stop charging, energy savings has also prolonged useful life of battery;
3. can stop the potential faults that contact reed charging modes brings fully.

Fig. 2 is the circuit theory schematic diagram of wireless charging microphone preferred embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
As shown in Figure 1, wireless charging microphone of the present invention comprises pick-up head 1 and the hand holding handle that links together, rechargeable battery 3 and induction coil 4 that described hand holding handle inside is provided with circuit board 2 and is electrically connected with described circuit board 2; Described pick-up head 1 is electrically connected with described circuit board 2, is used for gathering sound.Described induction coil 4 is arranged on the bottom of described hand holding handle, so that the convenient charging when inserting in the cradle of wireless charging microphone.
Be provided with power supply circuits and charging circuit on the described circuit board 2, described power supply circuits are used for to described pick-up head 1 power supply, and described charging circuit is used for to described rechargeable battery 3 chargings.Hand holding handle is the handgrip part of wireless microphone, and inside is provided with the parts such as voicefrequency circuit, rechargeable battery 3, power supply circuits, charging circuit and induction coil 4.Voicefrequency circuit is that the sound that pick-up head 1 collects is processed; Rechargeable battery 3 and power supply circuits are for powering to microphone; Induction coil 4 will carry out electromagnetic induction with the charging base that matches and generation current charges, and in Fig. 2, coil L namely is the induction coil 4 among Fig. 1.
Charging method of the present invention is by in wireless microphone inside induction coil being set, and charging circuit charges to the rechargeable battery in the wireless microphone.It specifically comprises the steps:
Step 1: wireless microphone is inserted on the cradle, and by described induction coil induction alternating current;
Step 2: described alternating current enters charging management chip through after shaping, filtering and the step-down;
Step 3: described charging management chip charges to described rechargeable battery;
Step 4: when the charging pin of described charging management chip detects setting voltage value, stop charging.
According to the method, wireless microphone charging circuit of the present invention comprises control chip, is connected with power supply module, charging circuit on the described control chip, and described charging circuit is connected with the induction charging module that is provided with induction coil.As shown in Figure 2, described control chip is charging management chip TP4056-42-SOP8-PP.Described induction charging module comprises induction coil 4 and rectification filtering module (being rectifier diode D1 shown in Figure 2 and filter capacitor C1, C2, C3 part).Described charging circuit comprises voltage reduction module (being chip IC 1 shown in Figure 2).This voltage reduction module adopts the existing step-down chip commonly used in market to get final product, so do not repeat them here.
