Claim Text:
1. A temperature alarm circuit for a hard disk device, the temperature alarm circuit comprising: a temperature detecting module configured to detect an internal temperature of the hard disk device; a control chip electrically coupled to the temperature detecting module and configured to receive the internal temperature and 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, wherein the control chip outputs a control signal to the voltage pull-up module; and an alarm module electrically coupled to the voltage pull-up module, wherein 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; wherein the voltage pull-up module pulls up voltage of the control signal, and transmits the voltage pulled up control signal to the alarm module.
