に鳴るため、使用者が気が付かないことはない。As the electronic device is used, the battery voltage gradually decreases as shown in FIG. At time t1, the battery voltage is vL
When the voltage reaches this voltage, the voltage detection section 2 detects this voltage and activates the alarm generation section. In this case, the second
In the configuration shown in the figure, since the speaker 5 is operated continuously, the battery voltage drops rapidly as shown by the broken line in FIG. 3 and reaches the device operating limit voltage vT at an early stage. When the alarm control section 3 is provided as shown in FIG. 3 and the alarm generation section 4 is operated intermittently at the time and interval determined by the alarm control section 3, the battery voltage gradually decreases as shown by the curve in FIG. These situations are shown enlarged in FIGS. 4a and 4b. According to the configuration of the present invention shown in FIG.
Since the device is operated intermittently, the battery voltage gradually decreases and reaches the device operating limit voltage VT at time 1a. In this case, since the alarm sound emitted from the speaker 5 is sounded intermittently, the user will not notice it.
