Circuit system 11 is the main circuit of bluetooth earphone, circuit system 11 has a processor 111, processor 111 can be central processing unit (Central Processing Unit, CPU), microprocessor (Microcontroller Unit, MCU) or system single chip (System on a Chip) etc.Battery 13 is the main circuits being used in bluetooth earphone powering.Normal open switch (Normally Open Switch) 15 is electrically connected battery 13, and keep open circuit in the ordinary course of things, but when normal open switch 15 is triggered by pressed by external force or characteristic signals, normal open switch 15 can be formed closed, and when pressed by external force or characteristic signals trigger disappearance, normal open switch 15 reverts back to open circuit again.The power switch of aforementioned normal open switch 15 normally bluetooth earphone.
Reset cell 17 electrical connection system circuit 11, battery 13 and normal open switch 15, and there is Resetting Switching 171 and a control circuit 173.Control circuit 173 is electrically connected Resetting Switching 171.In normal open switch 15 conducting continuously, when making electric energy to threshold level of control circuit 173 accumulation battery 13 of reset cell 17, Resetting Switching 171 ends and battery 13 is stopped power supply can to circuit system 11, so, portable electronic devices 10 can cut off the path of battery 13 confession electric energy to circuit system 11 by reset cell 17.
When opening portable electronic devices 10, user can short depression normal open switch 15, makes the of short duration conducting of normal open switch 15, and allows the electric energy of battery 13 supply power to circuit system, carried out start.After having started shooting, control circuit 173 does not operate, represent the electric energy of control circuit 173 not accumulation battery 13, now, the electric energy accumulated due to control circuit 173 does not reach threshold level, therefore, the conducting of processor 111 meeting Sustainable Control Resetting Switching 171, and allow the electric energy sustainable supply of battery 13 to circuit system.
When portable electronic devices 10 completes start, and under general service condition, if the careless short depression of user is to normal open switch 15, when the electric energy of namely control circuit 173 accumulation battery 13 does not reach threshold level, Resetting Switching 171 still continues conducting, to make battery 13 continued power can to circuit system 11.
It is significant to note that, when portable electronic devices 10 completes start, but crash, when representing that portable electronic devices 10 cannot normally be used, user just can press normal open switch 15 continuously, to make control circuit 173 accumulation electric energy to threshold level, now, Resetting Switching 171 can be cut off, and forms open circuit to make path between battery 13 and circuit system 11, and no longer supply electric energy to circuit system 11, reach the object resetting portable electronic devices 10.In addition, to restart, short depression normal open switch 15 is more only needed.
Figure 2 shows that a circuit diagram of portable electronic devices, this figure only represents the wherein circuit composition diagram realizing portable electronic devices 10 of the present invention, but not portable electronic devices 10 is construed as limiting, therefore, the built-up circuit of portable electronic devices 10 is not depicted as limit with this figure.
Control circuit 173 has an energy-storage units 175, in this embodiment, energy-storage units 175 is made up of a resistance R and two shunt capacitance C1, a C2, is used for receiving and the electric energy of storage batteries 13, so, control circuit 173 just can utilize this two electric capacity C1, C2 to carry out accumulation electric energy.
In addition, threshold level is the voltage quasi position of this two electric capacity C1, C2, threshold level is along with the actual appearance resistance value change of two electric capacity C1, C2 and resistance R, therefore, threshold level can adjust with actual demand, namely electric capacity C1, C2 quantity system of energy-storage units 175 can be changed, but minimum needs electric capacity and a resistance.
Referring again to Fig. 2, control circuit 173 also has releases energy unit 177.Release and can be electrically connected energy-storage units 175 by unit 177, discharge electric energy for energy-storage units 175.So, the electric energy that energy-storage units 175 stores just can discharge by unit 177 by releasing, and to avoid portable electronic devices 10, misoperation occurs.Particularly, when normal open switch 15 is by repeatedly short depression, the electric energy that energy-storage units 175 is accumulated also can discharge by unit 177 by releasing, to avoid energy-storage units 175 repeatedly accumulation electric energy and reach threshold level, therefore, portable electronic devices 10 of the present invention has preferably degree of stability.
