Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
Fig. 1 is the schematic diagram arranging detection switch on active foldable earphone in the embodiment of the present invention.See Fig. 1, the left detection that when a left side arm is folded state, disconnection, left side arm close when being open mode is set in the arm bending place, left side of active foldable earphone and switchs SW1；The right detection switch SW2 of Guan Bi when disconnection, right arm are open mode when one right arm is folded state is set in the right arm bending place of active foldable earphone.
If two detection switch SW1 and SW2 use "AND" logic, when i.e. two detection switches all close, earphone is just started shooting, and will shut down but as long as there being one to switch off earphone.The situation that when this logic meets that under use state, earphone is worn on the head, two, the left and right side arm of earphone all can be opened, but shortcoming is probably can miss by the bending of one of them side arm the switch of breaking inner when temporarily taking, thus earphone is shut down by mistake.So if it is desired that turn back on also needing to, and if bluetooth etc. need the earphone of pairing to be possible to the operation needing again to match, thus cause unnecessary trouble.
If two detection switch SW1 and SW2 use "or" logic, as long as i.e. two detection switches have a Guan Bi earphone to start shooting, when only two switches all disconnect, earphone just can shut down, the problem of this kind of logic maximum is: when being all likely to result in placement earphone in the case of Hen Duo, one side arm is opened and makes earphone open by mistake machine, thus earphone may be constantly in work power consumption state in the case of user is ignorant.
Therefore, give in the present invention a kind of more meet user use logical relation to control the switching on and shutting down of earphone, specific as follows:
1. start logic
Fig. 2 a, Fig. 2 b, Fig. 2 c and Fig. 2 d are the start logical specification schematic diagrams in the embodiment of the present invention.In the present invention, it is off-mode when earphone is in state shown in Fig. 2 a, is off-mode when being in state shown in Fig. 2 b, when being in state shown in Fig. 2 c, is still off-mode, until earphone just enters open state when being in that shown in Fig. 2 d, state can be worn on the head.
Why Fig. 2 b and Fig. 2 c two states are the side arm by mistake opening folding that off-mode is because that this two states is likely to artificial, do not want to open earphone, if this two state is put into open state and is likely to user and does not use earphone, simply earphone is opened by mistake and cause meaningless power consumption.
2. shutdown logic
Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 3 d are the shutdown logical specification schematic diagrams in the embodiment of the present invention.In the present invention, it is off-mode when earphone is in state shown in Fig. 3 a, when being in state shown in Fig. 3 b or Fig. 3 c, is still open state, until being in earphone when earphone is accepted by state completely shown in Fig. 3 d just enter off-mode.
Why Fig. 3 b and Fig. 3 c two states be open state be to prevent artificial merging from folding a side arm by mistake, but be not intended to close earphone, if this two state is put into off-mode and is likely to cause user to need to do the process action turned back on.
Use the above-mentioned start logic of the present invention and the logic method as the switching on and shutting down of active foldable earphone of shutting down, the people that press close to that can be maximum use the custom state of earphone, use and i.e. start shooting, do not use to pack up and i.e. shut down, avoid because forgeing shutdown and the puzzlement that causes, thus the inconvenience that causes because of power depletion of more efficiently solution and the saving that realizes the energy.
The concrete scheme realizing above-mentioned start logic and shutdown logic in the present invention given below.

Describe for convenience, marked tetra-points of A, B, C, D in Figure 5.
The concrete logic that controls of circuit shown in Fig. 5 is:
1, time initial, the left and right side arm of earphone is all that folded state, i.e. SW1 and SW2 all disconnect, and now A point and B point logic level are VBAT high level.C point is high level, and Q1 turns on, and Power_OFF signal is low level.D point is high level, and Q2 ends, this low level of Power_ON signal.Here Q1 is NMOS tube, and high level turns on, and Q2 is PMOS, and low level turns on.
2, open when a side arm of earphone, such as when left side wall is opened, SW1 closes, then A level point is become GND low level from VBAT high level, causes C point logic level to be become low from height, Q1 ends, Power_OFF is become high level, D point logic level constant holding high level from low level, and Q2 keeps by state, Power_ON signal keeps low level, does not produce starting-up signal.
3, same, if simply right arm is opened, i.e. SW2 closes, and B level point is become GND low level from VBAT high level, causes C point logic level to be become low from height, Q1 ends, Power_OFF is become high level, D point logic level constant holding high level from low level, and Q2 keeps by state, Power_ON signal keeps low level, still without producing starting-up signal.
4, if earphone left and right sides arm is opened simultaneously, i.e. SW1 and SW2 all closes, now A, 2 logic levels of B are become GND low level by VBAT high level, causing C level point is low level, Q1 ends, Power_OFF is high level, D point is then become low level from original high level, Q2 conducting makes Power_ON be become high level from low level, producing starting-up signal makes Q4 moment open by C2 and D5, again Q3 conducting is produced Power power supply signal to control unit, control unit work produces HOLD high level signal to the positive pole of D6, keep Power power supply signal, enter start duty.Here control unit can be a control module in the processor of earphone.
5, under the open state that earphone two side arms is all opened, if arm on the left of Zhe Dieing, then SW1 disconnects, A point logic level is become high from low, and B point logic level keeps low level constant, and C point logic level keeps low level constant, D point logic level is become high from low, Q2 ends, and Power_ON logic level is become low from height, and Q1 ends, Power_OFF logic level keeps high level, not producing the low level representing shutdown, therefore HOLD level is remained height by control unit, duty of persistently starting shooting.
6, same, after start, only Guan Bi right arm allows SW2 switch off, and result is with result the same will not produce Power_OFF low level signal is described above, and HOLD keeps high level, keeps start duty.
7, under the open state that earphone two side arms is all opened, if respectively left and right sides arm all being folded, i.e. SW1 and SW2 all disconnects, then 2 logic levels of A, B all become high level, making D level point is high level, Q2 ends, Power_ON is low level, C point is become high level from low-level logic, Q1 turns on, making Power_OFF be become low level from high level, control unit detects that Power_OFF is HOLD high level to be become low level after low level, makes Q3, Q4 power entrance off-mode by halt system.
