Abstract
The utility model discloses an electricity saving device-equipped microphone. The electricity saving device-equipped microphone comprises a microphone, a microphone body and a battery, wherein the microphone is arranged at the front end of the microphone body; a switch is arranged on the outer wall of the microphone body; the battery is controlled by the switch to supply power to the microphone; an energy-saving device is arranged inside the microphone body; when the microphone is not used, the energy-saving device can be used for disconnecting a circuit where electricity is supplied to the microphone by the battery. The electricity saving device-equipped microphone described in the utility model can automatically cut off electricity supply of the battery after the microphone does not receive voice signals for a certain time; and at the moment, a metal contact can be triggered again for enabling the microphone to work normally, and therefore the phenomenon that unnecessary power quantity consumption is caused because a user forgets to turn off a power source of the microphone can be prevented.
Description
Technical field
The utility model relates to a kind of improvement of microphone, refers in particular to a kind of power supply of closing microphone because forgetting of can preventing, causes the microphone with battery saving arrangement of the unnecessary consumption of electric weight.
Background technology
The appearance of microphone is carried out and is brought great convenience to our meeting, the annual quantity of ad hoc meeting room is also increasing gradually, and after meeting adjourned, particularly give lessons for student in instructors after end, the environment that speaker Chang Yinwei is numerous and disorderly and forget the power supply of closing microphone, causes the unnecessary consumption of electric weight; And dry cell is difficult to obtain correct recovery after being finished, excessive use, will be unfavorable for the improvement of environment; For this reason, we have researched and developed a kind of power supply of closing microphone because forgetting of can preventing, cause the microphone with battery saving arrangement of the unnecessary consumption of electric weight.
Utility model content
The utility model object is that a kind of power supply of closing microphone because forgetting of can preventing is provided in order to overcome the deficiencies in the prior art, causes the microphone with battery saving arrangement of the unnecessary consumption of electric weight.
For achieving the above object, the technical solution adopted in the utility model is: a kind of microphone with battery saving arrangement, comprises microphone, microphone, battery; Described microphone is arranged on the front end of microphone; On the outer wall of described microphone, be provided with switch; Described battery is microphone power by switch control; In described microphone, be provided with energy saver, described energy saver can cut off the circuit of the power supply that battery is microphone in the time that microphone does not use.
Preferably, described energy saver, comprises controller, metal contact piece, relay, capacitor C 1; Described metal contact piece is arranged on the outer wall of microphone, and is connected with controller by capacitor C 2; Described relay is connected with controller, and can control the power supply of battery; One end of described capacitor C 1 is connected with relay with controller respectively, and is connected with one end of battery, and the other end of capacitor C 1 is connected with the other end of battery by resistance R, and is connected with controller simultaneously.
Preferably, described resistance R is variable resistor.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The microphone with battery saving arrangement described in the utility model, can not receive after voice signal a period of time at microphone, automatically cut off the electric weight supply of battery, now, triggering metal contact piece can make microphone normally work again, prevent the power supply of closing microphone because forgetting thereby can reach, cause the situation of the unnecessary consumption of electric weight to occur.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The circuit theory diagrams of the battery saving arrangement that accompanying drawing 1 is the microphone with battery saving arrangement of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of microphone with battery saving arrangement described in the utility model, comprises microphone, microphone, battery; Described microphone is arranged on the front end of microphone; On the outer wall of described microphone, be provided with switch; Described battery is microphone power by switch control; In described microphone, be provided with energy saver, described energy saver can cut off the circuit of the power supply that battery is microphone in the time that microphone does not use; Described energy saver, comprises controller, metal contact piece, relay, capacitor C 1; Described metal contact piece is arranged on the outer wall of microphone, and is connected with controller by capacitor C 2; Described relay is connected with controller, and can control the power supply of battery; One end of described capacitor C 1 is connected with relay with controller respectively, and is connected with one end of battery, and the other end of capacitor C 1 is connected with the other end of battery by resistance R, and is connected with controller simultaneously.In the present embodiment, described controller adopts 555 chips; Described resistance R is variable resistor, controls microphone switching duration to facilitate.
In the time using microphone, open switch S 1, with hand touching sheet metal P, the noise signal of human body is added to the trigger end of 555 chips by capacitor C 2, make the output of 555 chips become high level from low level, relay K 1 adhesive, battery starts to microphone power; When battery is to microphone power, battery also starts to charge to capacitor C 1, and when the voltage of capacitor C 1 rise to battery voltage 2/3 time, the 7th pin conducting of 555 chips, discharges capacitor C 1.Now, the output of the pin 3 of 555 chips becomes low level from high level, and relay K 1 discharges, and the power supply of microphone is closed, and microphone quits work.
In the time that speaker need to continue to use, only need touch again sheet metal, just can make the power supply circuits of microphone again connect, microphone is worked on.The charging interval of capacitor C 1 is that microphone opens and closes duration, and time T=1.1R*C1.
For adapting to occasion demand, select variable resistor R, can control the microphone length of switching duration.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The microphone with battery saving arrangement described in the utility model, can not receive after voice signal a period of time at microphone, automatically cut off the electric weight supply of battery, now, triggering metal contact piece can make microphone normally work again, prevent the power supply of closing microphone because forgetting thereby can reach, cause the situation of the unnecessary consumption of electric weight to occur.
Below be only concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
