The cathode of the other end of resistance R2, the anode and diode D2 of diode D1, the other end of the cathode connection capacitance C3 of diode D1,
1 pin of resistance R3,4 pins of chip IC 1,8 pins of chip IC 1 and chip IC 2, the other end connection capacitance C4 of resistance R3
The other end, 2 pins of chip IC 1 and 2 pins of chip IC 2, the other end and two of the 3 pins connection relay J of chip IC 1
The cathode of pole pipe D3, the other end of another fixing end connection bluetooth headset of potentiometer RP1.
Preferred embodiment as the utility model：The relay J is HF32FA type normally opened relays.
Preferred embodiment as the utility model：The chip IC 1 is 555 time base circuits, and chip IC 2 is that TX982 types are micro-
Wave induction controller.
Preferred embodiment as the utility model：The dry cell or accumulator of the power supply E.
Compared with prior art, the utility model has the beneficial effects that：The detection mode of circuit is that TX982 types are microwave induced
Controller, it utilizes microwave Doppler effect, as long as will be reflected back when someone enters electric field in certain distance spatial dimension
Wave triggers the electric loop of bluetooth headset, and circuit is through incuding after a period of time less than microwave signal meeting after people leaves induction range
It is automatically closed, therefore use, on bluetooth headset, when people, which take earphone, not to be used, earphone can automatically power off, will not
Because forgetting to turn off the switch and cause the loss of electricity.
Description of the drawings
Fig. 1 is the circuit diagram of bluetooth sports earphones；
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, a kind of bluetooth sports earphones, including bluetooth headset, power supply E, chip IC 1 and relay J；The electricity
The anode connection resistance R2 of source E, the contact J-1 of capacitance C2 and relay J, the anode of the cathode connection diode D2 of power supply E, two
The anode of pole pipe D3,3 pins of capacitance C3, capacitance C4, relay J, chip IC 1,3 pins and bluetooth headset of chip IC 2, after
The sliding end of the fixing end and potentiometer RP1 of the other end connection potentiometer RP1 of the contact J-1 of electric appliance J, the other end of capacitance C2
The cathode of the other end of resistance R2, the anode and diode D2 of diode D1 is connected, the cathode connection capacitance C3's of diode D1
The other end of 1 pin of the other end, resistance R3,4 pins of chip IC 1,8 pins of chip IC 1 and chip IC 2, resistance R3 connects
2 pins of the other end of capacitance C4,2 pins of chip IC 1 and chip IC 2 are connect, the 3 pins connection relay J's of chip IC 1 is another
The cathode of one end and diode D3, the other end of another fixing end connection bluetooth headset of potentiometer RP1.
Relay J is HF32FA type normally opened relays.Chip IC 1 is 555 time base circuits, and chip IC 2 is TX982 type microwaves
Induction controller.The dry cell or accumulator of power supply E.
The operation principle of the utility model is：After people takes bluetooth headset, human body chance enters the microwave induced control of TX982 types
