ABSTRACT:
An electronic apparatus with a vibration informing function comprises a vibrating device capable of vibrating for providing information. A reference signal generation circuit outputs a reference signal for producing an operation timing signal. A vibration control device judges whether to vibrate the vibration device and outputs a vibration alarm ON signal in synchronism with the reference signal output by the reference signal generating circuit when it is judged to vibrate the vibration device. A vibrating device control circuit stores predetermined intermittent driving patterns and outputs one of the predetermined intermittent driving patterns in synchronism with the reference signal output by the reference signal generating circuit when the vibration alarm ON signal output by the vibration control device is input thereto. A vibrating device driving circuit outputs a driving signal for vibrating the vibrating device intermittently in response to the predetermined intermittent pattern output by the vibrating device control circuit.
