KR970071775A - Power-saving power control method and apparatus for audio system - Google Patents

Abstract

The present invention relates to a power consumption reduction type power supply control method and apparatus, and more particularly, to an audio system constituted by blocks, such as a tuner, a compact disc player and a cassette tape recorder, And more particularly, to a power-saving power control method and apparatus for an audio system for minimizing power consumption by supplying power only to a corresponding apparatus.

That is, the power supply unit 100 supplies power to the tuner 120, the kesset tape recorder 121, the compact disc player 122, the amplifier 130, and the turntable 123, A main input unit 160 connected to the main control unit 150 to select a system and a control unit 150 connected to the main control unit 150. The main control unit 150 controls the devices 120-123, And a display unit 170 connected to the display unit 170 for displaying a control state of the main controller 150. The audio system includes a plurality of devices for turning on and off the power applied to the devices 120-123 from the power supply unit 100 A main controller 150 for controlling the switches 110-114 and an amplifier 130 for controlling the sound of each device 120-123 under the control of the main controller 150, So that unnecessary power consumption can be minimized, and the power consumption of each device can be reduced. Which will remove the wait state to enhance the reliability of the audio system sikimeuro minimize deterioration or change in the component characteristics of each device.
