Abstract
A sound box control system includes a controller, a memory and an audio interface. The controller is used for determining whether the audio interface has any audio signal access or not. When the time in which the audio interface does not have any audio signal access reaches a preset time, the controller controls a power supply circuit to stop output power. The invention further provides a sound box control method. The sound box control system and the sound box control method are helpful to control energy saving of the system.

Embodiment
Please refer to Fig. 1, whether audio amplifier control system 10 of the present invention is for controlling a power circuit 40 for audio amplifier provides working power, and wherein this power circuit 40 is for being converted to the external power source of access the required power supply of audio amplifier.The better embodiment of this audio amplifier control system 10 comprises a controller 20 and a memory 30.This controller 20 can be the element with data-handling capacity, as microprocessor.In present embodiment, this controller 20 is connected with an audio interface 50, and to receive the audio signal of a computer output, also for controlling this power circuit 40, whether out-put supply is audio amplifier power supply.
In this memory 30, store a flag bit 300.This flag bit 300 has one first value.
This controller 20 comprises a detecting unit 200, a recognition unit 202 and a control unit 204.
Whether this detecting unit 200 has audio signal access for detecting this audio interface 50.In present embodiment, the first value of this flag bit 300 is set by this detecting unit 200.When there being audio signal when access, 200 of this detecting units value by this flag bit 300 changes to one second value, and this detecting unit 200 is also exported one first and controlled signal to this control unit 204 simultaneously; When there is no audio signal access, these detecting unit 200 output one first triggering signals are to this recognition unit 202.
When receiving the first triggering signal of these detecting unit 200 outputs, 202 of this recognition units judge the value of this flag bit 300 is duration of the first value whether to be greater than a Preset Time, when the duration that this flag bit 300 is the first value is not more than this Preset Time, these recognition unit 202 output one second control signals; When the duration that this flag bit 300 is the first value is greater than this Preset Time, this detecting unit 200 continues to judge whether this audio interface 50 has audio signal access.
This control unit 204 is for receiving the first control signal of these detecting unit 200 outputs and the second control signal of this recognition unit 202 outputs.When this control unit 204 receives the first control signal of these recognition unit 202 outputs, 204 of this control units are controlled these power circuit 40 out-put supplies, thereby make to control audio amplifier when having audio signal access, start working.Meanwhile, this control unit 204 is also exported one second triggering signal to this detecting unit 200, so that the value that this detecting unit 200 is reset this flag bit 300 is this first value.When this control unit 204 receives the second control signal of these recognition unit 202 outputs, 204 of this control units are controlled this power circuit 40 non-transformer outputs,, when audio amplifier absence of audio signal accesses, control audio amplifier and quit work, thereby reach energy-conservation object.
Please refer to Fig. 2, the better embodiment of audio amplifier control method of the present invention comprises the steps:
Step S1, this flag bit 300 of these detecting unit 200 initialization is one first value.
Step S2, this detecting unit 200 judges whether this audio interface 50 has audio signal access, when having audio signal access, execution step S3; When absence of audio signal accesses, these detecting unit 200 output first triggering signals, and perform step S5.
Step S3, the value that this detecting unit 200 arranges this flag bit 300 is the second value, and exports this first control signal, afterwards, execution step S4.
Step S4, controls this power circuit 50 out-put supplies after this control unit 204 receives this first control signal.
Step S5, this recognition unit 202 receives and judges this flag bit is duration of the first value whether to be greater than this Preset Time after these first triggering signals; When the time that this flag bit 300 is the first value is not more than Preset Time, return to step S2.
Step S6, when the time that this flag bit is the first value is greater than Preset Time, output second controls signal to this control unit 204; This control unit 204 receives after this second control signal, controls power circuit 40 and stops out-put supply.
Above-mentioned audio amplifier control system and method access by having judged whether audio signal, when absence of audio signal access or the access of absence of audio signal reach Preset Time, control the output of power circuit non-transformer, thereby have reached energy-conservation object.
