Embodiment
Below in conjunction with Figure of description, embodiment of the present utility model is described in detail.Obviously, described embodiment is only a part of embodiment of the present utility model, and other embodiment that those skilled in the art obtains under the prerequisite of not paying creative work, belongs to protection range of the present utility model.
The ultra-low power standby blue-tooth device that the utility model provides as Figure 1-3, comprise bluetooth earphone 1 and headset base 2, described bluetooth earphone comprises Bluetooth chip, the magnetic switch 13 being connected with Bluetooth chip communication, MCU_chargerPIN contact 11, GND contact 12, described headset base includes the stopper slot 21 of placing bluetooth earphone, this stopper slot 21 is a kind of " U " font groove, the magnetic switch 13 arranging on the corresponding bluetooth earphone of stopper slot 21, MCU_chargerPIN contact 11, GND contact 12 is provided with corresponding with it base magnet 24, charger_5v contact 22, GND contact 23.Wherein contact the signal producing with base magnet 24 be pulse signal to magnetic switch 13, described Bluetooth chip comprises the reset call module that the deep sleep module that triggered by low level and high level trigger, described deep sleep module is contacted and triggers with the base magnet of headset base by the magnetic switch on bluetooth earphone, the magnetic switch of described reset call module on bluetooth earphone do not trigger while not contacting with the base magnet of headset base, described charger_5v contact 22 contacts the charging circuit that forms bluetooth earphone with MCU_chargerPIN contact 11, described Bluetooth chip is provided with the first contact jaw that is subject to magnetic switch and the control of base magnet, at contact jaw rear, be provided with the ON/OFF interface of Bluetooth chip, the ON/OFF interface other end is directly connected to the start pin position of Bluetooth chip, on Bluetooth chip, be still provided with the second contact jaw that produces pulse signal, described the second contact jaw is subject to magnetic switch and base magnet is controlled, the second contact jaw is connected with Bluetooth chip communication by input/output end port, described headset base is provided with contact indicator light group 25, on these contact indicator light group 25 corresponding Bluetooth chips, respectively contact port.
The utility model operation principle circuit as shown in Figure 4, when earphone is put into base, two contact MCU_charger PIN of earphone, GND, with two contact charger_5v of base, GND contacts respectively; Simultaneously the normally closed magnetic switch of earphone is subject to the work that affects of base magnet, and wherein charger5V is just to headset batteries charging use.
When earphone is wanted penetration depth sleep pattern.Bluetooth earphone is put on base, after earphone and base contact.Earphone magnetic switch on schematic diagram is subject to the work that affects of base magnet (magnetic line of force), and magnetic switch is disconnected, and makes Q4 cut-off, and the ON/OFF interface of Bluetooth chip is in electronegative potential.The G pin of Q2 is also electronegative potential simultaneously, thereby makes the GPIO-1 of Bluetooth chip send a positive pulse, and GPIO-1 directly links main bluetooth IC.When bluetooth IC receives that, after the positive pulse that PIO8 sends here, main IC can automatic penetration depth sleep pattern.Standby current is now 0.5uA.
When needs are normally used earphone, need only earphone after base takes up, the magnetic switch of earphone loses the effect of magnet (magnetic line of force), magnetic switch conducting, thereby the G of Q4 is high level very, this Q4 conducting, thus ON/OFF end is high level, because ON/OFF end is the start pin position that is directly connected to bluetooth IC.Bluetooth IC receives that after the high potential pulse from ON/OFF end, IC can wake deep sleep mode up automatically, enters the function of normal start connected call.
Above; it is only preferred embodiment of the present utility model; but protection range of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
