Description
Technical field
The utility model relates to a kind of Wireless microphone device, relates in particular to a kind of Wireless microphone device that uses the wireless charging mode.
Background technology
The power supply of wireless microphone is all generally with dry cell or storage battery power supply at present, if use dry cell, need to change continually battery, not only cause energy waste, old and useless battery also can serious environment pollution, if use storage battery power supply, in the process of electric power storage, microphone generally need to be fixed on charger, can not use, only after charging is complete, could normally use, can not be with using with filling, very inconvenient.
Summary of the invention
The purpose of this utility model has been to provide a kind of Wireless microphone device that uses the wireless charging mode, and it has advantages of easy to use, energy-conserving and environment-protective.
The utility model is achieved like this, it comprises charging device and wireless microphone, it is characterized in that charging device is the horn-like structure of flared end sealing, charging device also comprises oscillating circuit, amplifying circuit and transmitting coil, oscillating circuit is connected with amplifying circuit, and amplifying circuit connects transmitting coil; Wireless microphone also comprises receiving coil, rectification circuit and charging circuit, and rectification circuit is connected with charging circuit, and rectification circuit connects receiving coil.
Technique effect of the present utility model is: the utility model takes full advantage of and charges the standby time of microphone, and with filling with use, charging operations is convenient, greatly facilitates the user, and safety and environmental protection.
Description of drawings
Fig. 1 is the functional-block diagram of charging device of the present utility model.
Fig. 2 is the functional-block diagram of wireless microphone of the present utility model.
Fig. 3 is structural representation of the present utility model.
Wireless microphone 2, charging device in the drawings, 1.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model is achieved like this, it comprises charging device 2 and wireless microphone 1, its structural principle is that charging device 2 is horn-like structures of flared end sealing, charging device 2 also comprises oscillating circuit, amplifying circuit and transmitting coil, oscillating circuit is connected with amplifying circuit, and amplifying circuit connects transmitting coil; Wireless microphone 1 also comprises receiving coil, rectification circuit and charging circuit, and rectification circuit is connected with charging circuit, and rectification circuit connects receiving coil; In charging device 2, voltage stabilizing circuit, oscillating circuit, amplifying circuit and transmitting coil consist of transmitting terminal.Wireless microphone 1, receiving coil, rectification circuit and charging circuit are connected, and consist of receiving terminal.When charging, as long as wireless microphone 1 is put into charging device 2, according to electromagnetic induction principle, transmitting coil and receiving coil consist of mutual inductor, electric energy passes to receiving coil by transmitting coil, then after passing through rectification circuit and charging circuit, completes the charging to wireless microphone 1.
