Abstract
The utility model microphone relates to a kind of rocking type wireless microphone, comprises the compositions such as microphone casing body, miaow head, circuit board, permanent magnet, spring, conductor piece, Li ion cells unit.When electric quantity of lithium ion batteries is sufficient, by lithium ion battery, powered, when electric quantity of lithium ion batteries is not enough, can rock microphone, by electromagnetic induction, producing electromotive force is lithium ion cell charging.
Description
Technical field
The utility model relates to a kind of microphone, relates in particular to a kind of wireless microphone that electric power is provided by electromagnetic induction.
Background technology
Wireless microphone is widely used in various places, as KTV, auditorium etc.The wireless microphone using at present is mainly divided into two kinds of moving-coil type and Electret Condencer Microphones, and supply power mode is all almost powered battery.Because wireless microphone power consumption is larger, use general powered battery, the service time of wireless microphone is shorter, uses inconvenience, and can consume a large amount of batteries, causes the pollution to environment.
Summary of the invention
The utility model provides a kind of rocking type wireless microphone, can solve the problem that general microphone service time of battery is too short, supply of electric power is not enough.
The utility model solves the technical scheme that its technical problem adopts: rocking type wireless microphone comprises microphone casing body, miaow head, controller, conductor piece, permanent magnet, spring, Li ion cells unit part.Miaow head is fixed on microphone casing body top; Controller is fixed on housing middle part; Conductor piece two ends are linking springs respectively, is fixed on lower housing portion, two blocks of permanent magnets of the corresponding placement in conductor piece both sides; Lithium ion battery is fixed on microphone casing body bottom.Controller comprises audio amplifier circuit, high-frequency oscillating circuits, voltage stabilizing circuit, rectification circuit, charge-discharge protection circuit etc.Wireless microphone under normal circumstances, is powered by lithium ion battery.When lithium ion battery electricity shortage, can rock microphone, allow conductor piece move therein, produce electric weight, thereby supplement because of the not enough electric weight lacking of powered battery.
The beneficial effects of the utility model are can extend the service time of wireless microphone, the consumption of reduction battery, energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram.
Embodiment
The utility model comprises microphone casing body 1, miaow head 2, controller 3, microphone switch 4, conductor piece 5, spring 6, permanent magnet 7, lithium ion battery 8.Miaow head 2 is fixed on microphone casing body 1 top; Controller 3 is fixed on the middle part of microphone casing body 1; Conductor piece 5 two ends are linking springs 6 respectively, is fixed on microphone casing body 1 bottom, two permanent magnets 7 of the corresponding placement in conductor piece 5 both sides; Lithium ion battery 8 is fixed on the bottommost of microphone casing body 1.Generally, when electric quantity of lithium ion batteries is sufficient, by lithium ion battery, be that whole system is powered.When lithium ion battery electricity shortage, now rock microphone, by the electric weight being produced by microphone bottom, be system power supply.
