PURPOSE:To reduce the quantity of effective power consumption for the remote control device using the voice of the TV picture receiver, the radio receiver and the like, by controlling the power source of the aural recognition group with the detection output of the aural detecting circuit within the remote controller. CONSTITUTION:The switch circuit 11 is turned on and off by the output of the aural detecting circuit 14, and the circuit 14 is always driven by the DC power source 9. Then an aural command given to the remote controller 10 is detected by the circuit 14. With this detection output, the circuit 11 is turned on to give an electric conduction to the remote controller 10. Then the aural recognizing action is carried out by the controller 10 to secure a remote control via an aural command. As a result, the effective power consumption can be reduced. |
