Description
Technical field
A kind of electric power controller and method for managing power supply refer to electric power controller and the method for managing power supply of a kind of use in the computer system with audio frequency output especially.
Background technology
General portable computer system (portable computer system) all uses the supply of battery as its power supply, because the function of portable computer system is increasing, the demand of its power supply also improves relatively, do not influencing under the normal operation of computer function, power management is very important for the portable computer system.
With reference to figure 1, be known portable computer system configuration diagram.Traditional portable computer system 1 has a central processing unit 12 (CPU), a hard disk 13 (Hard Drive), an audio board 14 (AudioBoard), a power supply unit 15 (Power Supply) and an electric power management circuit 17 (PMIC), and portable computer system 1 more is coupled with a display unit 2 (Monitor), as the usefulness of operation demonstration.
The electric power management circuit 17 of known portable computer system 1 is the situation that obtains hard disk 13, audio board 14 and display unit 2 work, when its working condition was in idle (idle status), electric power management circuit 17 promptly produced low electric source modes signal and gives central processing unit 12.According to low electric source modes signal, central processing unit 12 promptly works in a low electric source modes (Low Power Mode), and then reduces waste of electric energy, and reaches effective power management.Yet, this kind pattern is being saved on the electric energy, and its effect is quite limited, is in low electric source modes though reason is portable computer system 1, but power supply unit 15 is still also given hard disk 13, audio board 14 and display unit 2 at the supply electric energy, and forms power consumption.
So a known technology is arranged in addition, it improves with regard to the part of the audio board in the portable computer system separately, imitates to reach the fruit of saving electric energy.With reference to figure 2, be known portable computer system sound intermediate frequency plate circuit box synoptic diagram.Shown in Figure 2, audio board 3 has a power supply decline circuit 32 and couples an audio amplifier circuit 34 and a switching switch 36.In addition, audio amplifier circuit 34 more is coupled with an audio amplifier 4.When electric power management circuit 5 produces normal power supply, 32 meeting control its switch 36 conductings (ON) of power supply decline circuit, allow the supply voltage vcc that is coupled to change-over switch 36 can offer audio amplifier circuit 34, make its operate as normal, produce music and see through audio amplifier 4.When electric power management circuit 5 produced low power supply, power supply decline circuit 32 can control its switch 36 end (OFF), exports a block signal MUTE simultaneously and gives this audio amplifier circuit 34, makes it enter the sound blocking, and this moment, audio amplifier 4 stopped to produce music.
As shown in Figure 2, in traditional portable computer system, system takes to close the action of voice output and shutdown system when its power supply descends, and with the minimizing waste of electric energy, and reaches effective power management.Yet this kind power save mode system can influence the user when listoning music, and the shortcoming of suddenly complete staccato makes the user very inconvenient, and has reduced the quality of sound playing.
Summary of the invention
