PURPOSE:To realize a generation of a larger alarm voice according to approach a set time, by controlling the amplification degree of a sound volume amplifier in accordance with the difference between the set time and the present time. CONSTITUTION:The alarm time set by a setter 6 is read into a storage element 7 and compared with the present time obtained via a watch-use LSI2 through a comparator 8. Then a control is given so that the lower amplification factor of a variable amplifier 4 is obtained through the comparator 8 the larger the difference obtained through said comparison. As a result, a higher level is ensured for the alarm tone which is generated through a speaker 5 and via a synthesizer LSI, the amplifier 4 or the like according to approach the alarm set time. |
