Abstract
A distance detection system in an electronic device includes a vibration prompt circuit and a prompt module. The vibration prompt circuit includes a distance sensor, a processor, and a comparison module. The distance sensor is coupled to the processor. The processor is coupled to the comparison module. The comparison module is coupled to the prompt module. The distance sensor sends a distance value as to the distance between itself and a detected object to the processor. The processor converts the distance value to a current value and the current value is compared with a reference value. The prompt module activates a vibration device if the current value is greater than the reference value. A vibration prompt circuit and a vibration prompt method are also provided.
