ALARM AUDIO OUTPUT APPARATUS

摘要

An alarm audio output apparatus is provided to output audio signals through a sound generator equipped inside a television in case the audio signals are not outputted in the currently selected channel. A synchronization separator(10) separates a vertical synchronization signal and a horizontal synchronization signal from an image signal. A sound generator(30) outputs a stored audio signal through a speaker. A microcomputer(20) controls the power supply at a preset alarm time. If the horizontal and vertical synchronization signals are not separated from the current channel, the microcomputer controls the sound generator so as to output the audio signal through the speaker.
