Abstract

The invention relates to an alarm device comprising one buzzer, one fan, one detector and one fan controller. The buzzer is provided with a signal input end which is used for receiving a buzzing signal so that the buzzer is enabled to emit warning sound. The fan is used for heat radiation. The detector is connected with the signal input end so as to detect inputting of the buzzing signal to the buzzer and output a detection result. The fan controller receives the detection result and a working signal from a control device, and drives the fan to rotate according to the working signal and controls rotating speed of the fan according to the detection result. When the detection result indicates that there is no buzzing signal inputted to the buzzer, the fan controller controls the fan to rotate normally. When the detection result indicates that there is the buzzing signal inputted to the buzzer, the fan controller controls the fan to rotate in a deceleration way. The invention also relates to an alarm system comprising the alarm device.

Description

technical field [0001] The present invention relates to an alarm device and an alarm system with the alarm device. Background technique [0002] Electronic devices such as desktop computers or servers often use buzzers to sound an alarm when an internal system error or failure occurs. However, when the rotating speed of the fan used for heat dissipation is too fast and the noise is too high, the warning sound from the buzzer will be weakened, sometimes even causing the warning sound from the buzzer to be unable to be heard, which is not conducive to The user discovers the error or failure of the internal system in time. Contents of the invention [0003] In view of this, it is necessary to provide an alarm device capable of overcoming the above defects and an alarm system with the alarm device. [0004] An alarm device is used for alarming when a control device of electronic equipment generates a buzzer signal. The alarm device includes a buzzer, a fan, a detector and a...
