Alarm sounding apparatus for computer. |
摘要 |
<p>When a drop of the voltage of a battery is detected, a detector outputs two kinds of alarm signals in accordance with the degree of voltage drop. PALs 10 and 11 input the respective alarm signals to a selector 15. To the selector 15 are also supplied an alarm signal from a PAL 12 which generates an alarm signal in accordance with the state of a panel switch 4 and a sound signal from a speaker data generator 7. The selector 15 selects one from these signals so as to drive a speaker 8. Since a means for generating an alarm signal is provided exclusively for this purpose, an alarm sounding operation is ensured. <IMAGE></p> |
