Abstract

A vibration frequency adjusting system and method measures energy of a vibration generated by a vibrator of an electronic device, and converts the vibration energy to a level of electric charge. The system and method further compares the level of electric charge with preset electric charge thresholds, and adjusts the level of electric charge to a preset level of electric charge according to the comparison. Then, the system and method converts the adjusted preset level of electric charge to a voltage, and outputs the voltage to vibrator, so as to adjust the frequency of the vibration according to the voltage.
