A vibration gyroscope (10) includes a vibrator (12). The vibrator (12) has a vibration member (14) formed in a regular triangular prism shape. On side faces of the vibration member (14), three piezoelectric elements (16a, 16b, 16c) are formed, respectively. Two of the piezoelectric elements (16a, 16b) are connected to the input terminal of an oscillation circuit (20) through resistors (18a, 18b) which serve as the loads of the two piezoelectric elements (16a, 16b), respectively. The output terminal of the oscillation circuit (20) is connected to the other piezoelectric element (16c). The former piezoelectric elements (16a, 16b) are also connected to the non-inverting input terminal and the inverting input terminal of a differential amplifier circuit (22), respectively. By changing the impedances of the resistors (18a, 18b), the characteristics of the vibration gyroscope (10) is adjusted. <IMAGE> |
