Abstract
The utility model proposes a charging base for a wireless microphone. The charging base includes a casing. Charging insert slots used for connecting the microphone in a plugging manner are arranged in the casing. Charging coils are wound outside the charging insert slots. The charging coils are connected with a charging circuit board. The charging base of the wireless microphone charges a battery of the wireless microphone through adoption of a non-contact wireless charging technology and enables manpower cost brought by a dismounting-type charging method to be reduced. The charging base is capable of automatic power off so that energy is saved and service life of the battery is prolonged and is also capable of eliminating completely hidden danger of faults brought by a contact-type reed charging method.
Description
Technical field
The utility model relates to mechanical field, refers to especially a kind of wireless microphone charging base.
Background technology
Current wireless microphone battery on the market has two kinds of charging modes.A kind of be by battery from microphone, splitting out, utilize seat to be charged into the row charging.Charging need to split microphone and battery like this, troublesome poeration; And, after battery is full of electricity, also be difficult to accomplish timely deenergization, and not only cause the waste of the energy, also can shorten the useful life of battery.Another kind of charging modes is the contact charging, and generally by the contact reed power taking of microphone hand holding handle bottom, and this reed is after repeatedly using, or gets rusty easily in the middle of moist environment, thus initiating failure.
Above problem is all because the design defect of the charging modes of wireless microphone battery causes.The energy waste brought due to the traditional charge mode of wireless microphone battery and be easy to initiating failure, therefore be necessary its charge mode is improved.
The utility model content
The utility model proposes a kind of wireless microphone charging base, solved the energy waste that traditional charging method brings and the problem that is easy to initiating failure.
The technical solution of the utility model is achieved in that
A kind of wireless microphone charging base, it comprises housing, on described housing, is provided with the charging slot of grafting wireless microphone, and described charging slot is around with charge coil, and described charge coil is connected with charging circuit board.
Preferably, on described charging circuit board, be provided with the control switch chip, the induction charging module that is connected with power supply module, charging circuit on described control switch chip and is provided with described charge coil.
Preferably, described control switch chip is chip STC11F04.
Preferably, on described housing, also be provided with charge switch.
Preferably, on described housing, be provided with the charging slot of a plurality of grafting wireless microphones.
Preferably, a side of each described charging slot is provided with charging indicator light.
Preferably, on described housing, be provided with supply hub.
The utility model adopts the charging of contactless wireless charging technology to the wireless microphone battery, has following beneficial effect:
1. reduce the human cost that the detachable charging modes brings;
But automatic disconnection charge mode after the charging, stop charging, energy savings, also extended useful life of battery;
3. can stop the potential faults that contact reed charging modes brings fully.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective structure schematic diagram of a kind of wireless microphone charging base of the utility model preferred embodiment;
Fig. 2 is the plan structure schematic diagram of wireless microphone charging base preferred embodiment shown in Figure 1;
Fig. 3 is the circuit theory diagrams of the utility model wireless microphone charging base charging circuit board.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, wireless microphone charging base of the present utility model comprises housing 1, on described housing 1, is provided with the charging slot 2 of grafting wireless microphone, and described charging slot 2 is around with charge coil 3, and described charge coil 3 is connected with charging circuit board 4.Described charging circuit board 4 also is connected with an external power supply jack 5, to access external power supply.Charge coil 3 in Fig. 1 is namely the coil L1 in Fig. 3.
When the hand holding handle of wireless microphone was inserted in wireless microphone charging base of the present utility model, the charge coil 3 in the wireless microphone charging base passed through the induction generation current with the induction coil in wireless microphone, and the battery in wireless microphone is charged.
On described charging circuit board, be provided with the control switch chip, the induction charging module that is connected with power supply module, charging circuit on described control switch chip and is provided with charge coil 3.As shown in Figure 3, in preferred embodiment of the present utility model, described control switch chip is chip STC11F04.Because chip STC11F04 is existing product, its each pin definitions can, referring to its databook, not repeat them here.
The components and parts E2 and the C7 that with the VCC pin of chip STC11F04, are connected are the power filter effects, and LED3-R is power supply indicator; Because chip STC11F04 electric current and voltage out is all little, therefore need between chip STC11F04 and coil L1, increase drive circuit, i.e. illustrated amplifier Q2, the components and parts circuit such as Q3, Q3.
Described control switch chip can be controlled following charge mode: when the battery of wireless microphone was full of electricity or wireless microphone hand holding handle and leaves charging base, charging base of the present utility model can stop charging automatically.In conjunction with illustrated circuit diagram, its detailed process is: when the battery of wireless microphone is full of electricity, the P10 pin of chip STC11F04 can detect 5 volts of high level of long period, chip STC11F04 is set to 0 volt of low level to P10,3 radio waves that no longer send fixed frequency of charge coil, stop charging; When the wireless microphone hand holding handle leaves charging base, the P10 pin of chip STC11F04 also can detect long 5 volts of high level, chip STC11F04 also is set to 0 volt of level to P10, and coil namely no longer sends the radio wave of fixed frequency, and charging process will be interrupted automatically.
On described housing 1, also be provided with charge switch 6.To control the break-make of charging circuit.On described housing 1, also be provided with the charging slot of a plurality of grafting wireless microphones, namely can to a plurality of wireless microphones, fill simultaneously and in a side of each charging slot, charging indicator light 7 is set, to show respectively the charged state of each wireless microphone.
The utility model adopts the charging of non-contact type wireless charging technique to the wireless microphone battery, can reduce the human cost that the detachable charging modes brings, but and the auto-breaking energy savings, extend useful life of battery; Also can stop the potential faults that contact reed charging modes brings fully.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
