Abstract

타이머 기능을 갖춘 음성신호 출력기기에 있어서, 타이머 '온'시 음성신호 레벨이 낮을 경우 사용자가 인식하지 못하게 되는 불편을 해소시키도록 한 것으로 타이머 기능을 갖춘 마이콤(IC1)에서 타이머 '온'시 제어신호와 일정레벨 이상의 알람신호를 출력시키게 구성하고 상기 마이콤(IC1)의 제어신호로 스위칭 소자(IC2)의 구동을 스위칭 시켜 마이콤(IC1)의 알람신호 및 음성신호 출력부(10)의 음성신호를 선택적으로 스피커(SP)에 인가시키도록한 것으로서 타이머 '온'시 일정레벨 이상의 알람신호가 출력되어 자면종을 대신하여 기상시간을 충분히 인식할 수 있게 된다.Voice signal output device with a timer function, to solve the inconvenience that the user does not recognize when the voice signal level is low when the timer 'on', control when the timer 'on' from the microcomputer (IC1) equipped with the timer function Signal and an alarm signal of a predetermined level or more and outputs the alarm signal of the microcomputer IC1 and the audio signal of the audio signal output unit 10 by switching the driving of the switching element IC2 with the control signal of the microcomputer IC1. As it is selectively applied to the speaker (SP), when the timer 'on' is output an alarm signal of a certain level or more, it is possible to sufficiently recognize the wake up time in place of the sleeping species.

Claims

In a voice signal output device for driving a timer 'on' time set in a microcomputer IC1 having a timer function to output a voice signal of the voice signal output unit 10 to a speaker SP, the timer in the microcomputer IC1 An output terminal P2 for outputting an alarm signal when it is 'on' and an output terminal P1 for outputting an alarm signal output control signal, and the alarm signal output of the microcomputer IC1 and the voice of the audio signal output unit 10 are provided. And a switching element IC2 for switching the signal output to the alarm signal output control signal of the microcomputer IC1 and applying it to the speaker SP.

The alarm operation circuit of claim 1, wherein the alarm signal of the microcomputer IC1 is configured to be output at a level that is recognizable by the user.
