Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of working method of earphone.
Referring to Fig.1, Fig. 1 is the flow diagram of the working method first embodiment of earphone of the present invention.
In the first embodiment, the working method of the earphone includes:
Step S10 controls the micro-control in earphone when detecting that playing relevant operational module to audio in earphone opens
Unit processed enters default low-power consumption mode；
In the present embodiment, earphone includes various functional modules, if headset system may include bluetooth module, microcontroller
Unit (Microcontroller Unit, abbreviation MCU), noise reduction module, embedded rechargeable battery, audio assist import and export
(AUX) module etc., AUX mouthfuls external, external key etc. all pass through general input/output port (General Purpose Input
Output, abbreviation GPIO) it is connected on MCU, battery provides power supply for the work and detection of earphone system modules, it is not
Detachable and interchangeable, therefore, the endurance of battery determines the working time of earphone system.
Wherein, control centre of the MCU as earphone system controls the on and off and external key of modules
Detection, outside AUX plug detection etc. are related to audio broadcasting realizing although MCU is the control centre of entire earphone system
Function such as Bluetooth music play, telephony feature and AUX music playback function etc. whens, MCU does not need to participate in the tool of function
Body executes in operation, only needs bluetooth module, noise reduction module, audio auxiliary output module etc. are independent to realize respective Bluetooth music
Broadcasting, noise reduction, audio auxiliary output input function.Therefore, relevant to audio broadcasting in earphone when detecting in the present embodiment
When operational module such as bluetooth module, noise reduction module, audio auxiliary output module etc. is opened, the MCU in earphone can control to enter
Default low-power consumption mode, in this way, can't be played to bluetooth module, noise reduction module, audio auxiliary output module etc. with audio
Relevant operational module realizes that respective Bluetooth music broadcasting, noise reduction, audio auxiliary output input function have any impact, and
And MCU can reduce the operating current of MCU in default low-power consumption mode, to reduce the operating current of system, extend earphone system
The working time of system.It should be noted that the default low-power consumption mode of MCU can be deep power down mode, either shallow suspend mode
