Problems solved by technology
[0005] However, the design of the current HOLD key only solves the problem of the user's misoperation of the keyboard, but in actual conditions, after the user uses the key to lock, the user generally puts the multimedia terminal device in a pocket, bag, or hangs it on the chest. Do not look at the display screen, which will cause the power consumption of the display screen in vain
[0006] In addition, since users sometimes use these devices before going to bed and often forget to turn off the power, it will also cause a large drain on the battery
[0007] None of the functions provided by the existing HOLD key can solve the above problems, so providing a power management system and method for power saving mode has become a necessary research topic

Embodiment Construction
[0025] The preferred embodiment of the present invention is an MP3 player 1 that is provided with a HOLD key on it, with reference to Fig. 1, comprises controller 11, HOLD key 12, state detection module 13, timer 14, button device 15, OLED display screen wherein 16. Display power controller 17, power controller 18 and an electronic circuit device 19.
[0026] The controller 11 is provided with a state detection module 13 for detecting the state of the HOLD key 12 , and the controller 11 responds to the key device 15 through the detection signal of the state detection module 13 . As shown in FIG. 1 , the user can set the HOLD key 12 into two states, one is the locked state when the HOLD key 12 is connected to a high level, and the other is an unlocked state when the HOLD key 12 is connected to a low level. When the user HOLD key 12 is set to the unlocked state, the controller 11 sends instructions to the electronic circuit device 19, and then the electronic circuit device 19 pe...

A power supply management system of mobile terminal device comprises display screen, power supply controller of display screen, key unit, power supply controller, selection unit of key state, timer and controller for locking key unit when locking state of said selection unit is detected by controller and for switching display screen to be low power consumption state through power supply controller as well as for starting up time and switching power supply off through power supply controller if nonlocking state of said selection unit is detected by controller before timer is stopped.
Description
technical field [0001] The invention relates to a multimedia mobile terminal device, in particular to a power supply management system and method for a multimedia mobile terminal device. Background technique [0002] Along with the rise of the multimedia mobile terminal equipment with digital music (audio) playing function, various light and small mp3 players, music mobile phone equipment are used in a large number like mushrooms after rain. These multimedia mobile terminal devices can be placed in backpacks and pockets at will, which means that they can be activated by the buttons on them at any time, and sometimes the user activates them by accidentally touching the buttons without intention , which can cause unnecessary drain on the battery power of these devices. [0003] As an audio playback device, longer playback time is an important indicator of the product. Therefore, how to improve the working time of equipment through reasonable power management scheme design ha...
