Abstract
A hard disk device includes a main body and a temperature alarm circuit. The temperature alarm circuit includes a temperature detecting module detecting an internal temperature of the hard disk device, a control chip electrically coupled to the temperature detecting module to receive the internal temperature and configured to compare the internal temperature with a first preset temperature and a second preset temperature, a voltage pull-up module electrically coupled to the control chip, and an alarm module electrically coupled to the voltage pull-up module. The control chip outputs a control signal to the voltage pull-up module, the voltage pull-up module pulls up voltage of the control signal, and transmits the voltage pulled up control signal to the alarm module, and the alarm module alarms, in event that the internal temperature is higher than or equal to the first preset temperature or less than or equal to the second preset temperature.
