Abstract
PURPOSE:To reduce power consumption of the receiver, by discriminating the emergency alarm broadcast to control the operation of the voice output circuit and by detecting the receiving state to switch the alarm discriminating circuit to the operation state or the stop state. CONSTITUTION:When the emergency alarm broadcast is detected, alarm discriminating circuit 4 discriminates this broadcast, and voice amplifying circuit 2 is controlled by alarm discriminating circuit 4 so that the alarm broadcast is outputted from speaker 3 surely. Signal detecting circuit 5 detects the level of the intermediate- frequency signal from signal receiving part 1, and this circuit 5 operates to supply power to alarm discriminating circuit 4 only when the broadcast wave is detected or a prescribed intermediate-frequency signal level or more is detected.
